How to prevent that 2 LinkButtons get separeted by line break in Repeater? - html

I have a Repeater with 2 LinkButtons that need to be displayed next to each other to build a graphical unit. Depending on the window size the line break would break that unit. How can I tie these 2 elements together? I was fiddling with div but the result was that each result of the repeater is displayed in a new row, while I need them to be displayed horizontal.
<asp:Repeater runat="server" id="RepeaterUsers" >
<ItemTemplate>
<div style="display:inline;">
<div style="white-space:nowrap;">
<asp:LinkButton ID="LB1" runat="server" OnClick="SelectUser"><asp:Label runat="server" Text='<%# Bind("Name") %>' ID="RepeaterName"/>
</asp:LinkButton><asp:LinkButton ID="LB2" runat="server" OnClick="EliminateUser"><img src="img/close33.png"></asp:LinkButton></div><asp:Label runat="server" Text=" " Height="24px" ID="LabelSpace"/></div>
</ItemTemplate>
</asp:Repeater>
The final solution is:
<asp:Repeater runat="server" id="RepeaterUsers" >
<ItemTemplate>
<div style="float:left">
<table class="RepeaterTable">
<tr>
<td class="RepeaterTD">
<asp:LinkButton ID="ButtonHWReminderAudit" runat="server" OnClick="SelectUser" Font-Size="11px" CommandArgument='<%# Bind("Name") %>' CssClass='<%# Eval("CSSName") %>' ><%# Eval("DisplayName") %></asp:LinkButton></td>
<td class="RepeaterTD">
<asp:LinkButton ID="LinkButton4" runat="server" CommandArgument='<%# Bind("Name") %>' OnClick="EliminateUser" Font-Size="11px" CssClass='<%# Eval("CSSX") %>'>
<img src="img/close33.png" border="0" style="vertical-align:text-bottom;height:21px"></asp:LinkButton></td>
<td class="RepeaterTD">
<asp:Label runat="server" Text=" " Height="25px" ID="LabelSpace"/></td>
</tr>
</table>
</div>
</ItemTemplate>
</asp:Repeater>
and CSS:
.RepeaterTable {border-spacing:0;border-collapse:collapse;float:left;}
.RepeaterTD {padding: 0px;}
The column "Name" carries white spaces which occasionally might lead to a line break within one cell. Therefore I had to replace whitespace with a non-breakable-space (nbsp;) first.
In order to avoid gaps between the cells, you have to set spacing and padding to 0. This would provoke that no distance is kept between the tables. To set horizontal and vertical distances I added an additional cell.

I think you are looking for float: left
<asp:Repeater runat="server" ID="RepeaterUsers">
<ItemTemplate>
<div style="float: left; margin-bottom: 24px; clear: both">
<asp:LinkButton ID="LB1" runat="server"><%# Eval("Name") %></asp:LinkButton>
<asp:LinkButton ID="LB2" runat="server"><img src="img/close33.png"></asp:LinkButton>
</div>
</ItemTemplate>
</asp:Repeater>
Update
You could also use a table to align items, that always works. Although that is a bit old-school and against HTML-purists.
<table cellspacing="0" cellpadding="3" border="0">
<asp:Repeater runat="server" ID="RepeaterUsers">
<ItemTemplate>
<tr>
<td>
<asp:LinkButton ID="LB1" runat="server"><%# Eval("Name") %></asp:LinkButton>
</td>
<td>
<asp:LinkButton ID="LB2" runat="server"><img src="img/close33.png"></asp:LinkButton>
</td>
</tr>
</ItemTemplate>
</asp:Repeater>
</table>

There are 2 solution for you to remove redundant <td> </td>
Javascript version
var table = document.getElementById("mytable");
for (var i = 0; i < 3; i++) {
for (var k = 0; k < 5; k++) {
var str = table.rows[i].cells[k].innerHTML;
str = str.replace(/( )*/g, '');
if (str.length) alert(str);
}
};
How to remove with javascript this case?
Jquery version
$(function() {
$("table tr").each(function() {
var tds = $(this).find("td"); //find all td
var descriptionTD = tds.eq(1); //get the td for the description
//get the remaining tds that only contain " "
var emptytds = tds.not(descriptionTD).filter(function() {
return $(this).html() === " ";
});
//if all the remaing tds are empty
if (emptytds.length === tds.length - 1) {
emptytds.remove();
descriptionTD.prop("colspan", tds.length).prop("width", "100%");
}
});
});
remove <td> that has and make sub header
<td> </td>
Its the recommended pattern, cause it works on every browser. Try to run your table without &nbsp in Edge Browser, you will see that breaks the table layout.
<td>/td>
Without '&nbsp'
<td> </td>
With '&nbsp'

How do I hide/show a DIV inside a grid ItemTemplate?

I want to set individual DIVs inside a grid visible/hidden programmatically like so, but it isn't working. How would you fix this code?
foreach (DataGridItem dgItem in dgW.Items)
{
HtmlGenericControl dvGoodRow =
(HtmlGenericControl)dgItem.FindControl("dvGoodRow");
HtmlGenericControl dvBadRow =
(HtmlGenericControl)dgItem.FindControl("dvBadRow");
dvGoodRow.Visible = true;
dvBadRow.Visible = false;
}
Debug sessions show that the Visible attribute I set above does take effect at least in my watch window, but visually on the browser I see no change. I have a grid like the one below:
<asp:datagrid id="dgW" AutoGenerateColumns="False" ShowHeader="False" ShowFooter="False" runat="server" DataKeyField="SID" CellPadding="0" GridLines="None" AllowSorting="True" OnItemDataBound="dgW_ItemDataBound">
<HeaderStyle />
<FooterStyle>
</FooterStyle>
<Columns>
<asp:TemplateColumn HeaderText="SID" SortExpression="SID">
<ItemTemplate>
<asp:Label ID="lblSID" Runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "SID") %>'></asp:Label>
</ItemTemplate>
<FooterTemplate>
</FooterTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn HeaderText="Extension" SortExpression="ExtensionStopDate">
<ItemTemplate>
<asp:Label id="lblExtensionStopDate" Runat="server" text='<%# String.Format("{0:MM/dd/yyyy}", DataBinder.Eval(Container.DataItem, "ExtensionStopDate"))%>'></asp:Label>
</ItemTemplate>
<FooterTemplate>
</FooterTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn>
<ItemTemplate>
<div id="dvGoodRow" runat="server" hidden>
<div>
<asp:Label runat="server" ID="lblGoodRow">
<i id="icnGoodRow" runat="server"></i>
</asp:Label>
</div>
</div>
<div id="dvBadRow" runat="server" hidden>
<div>
<asp:Label runat="server" ID="lblBadRow">
<i id="icnBadRow" runat="server"></i>
</asp:Label>
</div>
</div>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:datagrid>
Remove that 'hidden' property and use visible
<div id="dvGoodRow" runat="server" visible="false">
<div id="dvBadRow" runat="server" visible="false">
Here's what I ended up doing to fix the code: I switched to showing/hiding ASP.NET Panels instead of DIVs!
<asp:TemplateColumn>
<ItemTemplate>
<asp:Panel runat="server" ID="pnlGoodRow" Visible="False">
<div id="dvGoodRow">
<asp:Label runat="server" ID="lblGoodRow">
<i id="icnGoodRow" runat="server"></i>
</asp:Label>
</div>
</asp:Panel>
<asp:Panel runat="server" ID="pnlBadRow" Visible="False">
<div id="dvBadRow">
<asp:Label runat="server" ID="lblBadRow">
<i id="icnBadRow" runat="server"></i>
</asp:Label>
</div>
</asp:Panel>
</ItemTemplate>
</asp:TemplateColumn>
So in the code, I now hide/show the Panel elements instead of DIVs:
foreach (DataGridItem dgItem in dgW.Items)
{
System.Web.UI.WebControls.Panel pnlGoodRow =
(System.Web.UI.WebControls.Panel)dgItem.FindControl("pnlGoodRow");
System.Web.UI.WebControls.Panel pnlBadRow =
(System.Web.UI.WebControls.Panel)dgItem.FindControl("pnlBadRow");
pnlGoodRow.Visible = true;
pnlBadRow.Visible = false;
}
This works!

UpdatePanel does not update data, some of the time. Sometimes there are long delays

I have an UpdatePanel that has another Panel inside to mimic a simple pop-up window.
Inside the Panel I have a HTML Table, with several rows and a few columns, and a GridView in one row and a DetailsView further down.
There is also an SUBMIT and a CANCEL button on the HTML table side.
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

<asp:PostBackTrigger ControlID="ButtonSubmit" />
<asp:PostBackTrigger ControlID="ButtonCancel" />

The problem is that when ever I SUBMIT a new tenant into the GridView gvAllocations, sometimes the server does a PostBack, other times it does nothing and the page is refreshed without the new entry shown in the Gridview. However, in the later case the page is refreshed properly after about 15-20 seconds and I can see the new tenant added into the GridView. Other times, it happens instantly.
I've tested the SQL server side-by-side with this, and the INSERT is working and I can see the new row immediately, but for some reason the ASP.net page does not register this, but only after 15-20 seconds. And as I said, this happens some of the time, which is even more frustrating.
Strangely, when ever I delete a tenant from the gvAllocations GridView, the whole thing works perfectly.
I am not sure if it's the UpdatePanel the issue here, or that this is perhaps poor design on my part and I should have used a FormView for the entire thing. Can you have FormViews inside UpdatePanels? Do I even need an UpdatePanel?
I've read this, and putting the ScriptManager RegisterPostBackControl() did not change anything for me.
Incidentally, the SUBMIT button renders as follows ...
<input type="submit" name="ctl00$ContentPlaceHolder1$ButtonSubmit" value="Submit" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$ContentPlaceHolder1$ButtonSubmit", "", true, "vg1", "", false, false))" id="ctl00_ContentPlaceHolder1_ButtonSubmit">
The CANCEL button does not have the WebForm_DoPostBackWithOptions(). Why?
Thank you for your time.
Well it looks like no one could help me out here and I was about to place a Bounty, but I found the culprit!
Yep - you've guessed it - Parameter Sniffing! It took me 4 days to figure it out.
The dvRoomCheckIn DetailsView had three parameters pre-designed into the control by myself, as you can see in the above code - the parameters were DateCheckedIn, CheckedINby, and ExpectedCheckOut.
The Stored Procedure was like this ...
CREATE PROCEDURE [dbo].[spBoardingCheckIN]
#StudentID CHAR(10),
#TenantID VARCHAR(20) = NULL,
#BedID INT,
#BoardingRoomID INT,
#BoardingTypeID INT,
#StaffID VARCHAR(10),
#ExpectedCheckOut DATETIME,
#Notes VARCHAR(5000)
AS
BEGIN
INSERT INTO tblBoardingCheckins(StudentID,
TenantID,
BedID,
BoardingRoomID,
BoardingTypeID,
DateCheckedIn,
CheckedINby,
ExpectedCheckOut,
Notes,
IsActive)
VALUES (#StudentID,
#TenantID,
#BedID,
#BoardingRoomID,
#BoardingTypeID,
GETDATE(),
#StaffID,
CONVERT(DATETIME, #ExpectedCheckOut, 121),
#Notes,
1)
END
GO
So what happened was that since I did not specify those three parameters into the Stored Procedure (I've defaulted the values and only mentioned one of them), the ASP.net (or SQL server?) went to find the values for the other two parameters that I mentioned in the DetailsView.
The way I fixed it was to specify all the Parameters that ASP.net expected, and therefore I changed the Stored Procedure and the parameter list in ASP.net to reflect the exact number of parameters expected, so as to avoid the program going into "sniffing" mode for those values.
ie
CREATE PROCEDURE [dbo].[spBoardingCheckIN]
#StudentID CHAR(10),
#TenantID VARCHAR(20) = NULL,
#BedID INT,
#BoardingRoomID INT,
#BoardingTypeID INT,
#DateCheckedIn DATETIME,
#CheckedINby VARCHAR(10),
#ExpectedCheckOut DATETIME,
#Notes VARCHAR(5000)
AS
BEGIN
INSERT INTO tblBoardingCheckins(StudentID,
TenantID,
BedID,
BoardingRoomID,
BoardingTypeID,
DateCheckedIn,
CheckedINby,
ExpectedCheckOut,
Notes,
IsActive)
VALUES (#StudentID,
#TenantID,
#BedID,
#BoardingRoomID,
#BoardingTypeID,
#DateCheckedIn,
#CheckedINby,
CONVERT(DATETIME, #ExpectedCheckOut, 121),
#Notes,
1)
END
GO
And the SqlDataSource in ASP.net is thus ...
<asp:SqlDataSource ID="sdsCheckinEntries" runat="server" ConnectionString="<%$ ConnectionStrings:ATCNTV1ConnectionString %>"
InsertCommand="spBoardingCheckIN" InsertCommandType="StoredProcedure" EnableCaching="false">
<InsertParameters>
<asp:ControlParameter ControlID="dvRoomCheckIn$ddlTenant" Name="StudentID" Type="string" />
<asp:Parameter Name="TenantID" Type="string" DefaultValue="" ConvertEmptyStringToNull="true" />
<asp:ControlParameter ControlID="dvRoomCheckIn$ddlBeds" Name="BedID" Type="int16" />
<asp:ControlParameter ControlID="lblSelectedRoomID" Name="BoardingRoomID" Type="Int16" />
<asp:Parameter Name="BoardingTypeID" Type="int16" DefaultValue="2" />
<asp:ControlParameter ControlID="dvRoomCheckIn$lblCheckedIN" Name="DateCheckedIn" Type="DateTime" />
<asp:ControlParameter ControlID="dvRoomCheckIn$lblCheckedINby" Name="CheckedINby" Type="string" />
<asp:ControlParameter ControlID="dvRoomCheckIn$txtCheckOUT" Name="ExpectedCheckOut" Type="DateTime" />
<asp:ControlParameter ControlID="dvRoomCheckIn$txtNotes" Name="Notes" Type="String" />
</InsertParameters>
</asp:SqlDataSource>
So yeah lessoned learnt! Don't assume that just because a parameter exists in a control that it's automatically and directly linked to the datasource. Sometimes, the program may not "find it" and has to go looking for values in relation to the parameters missing.
A great resource - if not the best I've found so far is this. It explains everything.
I hope this will help someone else out there pulling their hair out!

how to make the content inside div to display in one line

I have 4 labels inside a div, it looks like this:
I want them to display in one single line, how do I do this?
The code for labels:
<div style="float:left; width:50%">
<asp:UpdatePanel ID="loginPanel" runat="server" UpdateMode="Always">
<ContentTemplate>
<asp:Label ID="LoginLabel" runat="server" CssClass="label-info" Font-Bold="true" ForeColor="White" Width="300px"/>
</ContentTemplate>
</asp:UpdatePanel>
<%--Login ID--%>
<asp:UpdatePanel ID="RolePanel" runat="server" UpdateMode="Always">
<ContentTemplate>
<asp:Label ID="ShowRole" runat="server" CssClass="label-info" Font-Bold="true" ForeColor="White" Width="300px"/>
</ContentTemplate>
</asp:UpdatePanel>
<%-- role --%>
<asp:UpdatePanel ID="timePanel" runat="server" UpdateMode="Always">
<ContentTemplate>
<asp:Label ID="ShowTime" runat="server" CssClass="label-info" Font-Bold="true" ForeColor="White" Width="300px"/>
</ContentTemplate>
</asp:UpdatePanel>
<%--<br />--%>
<asp:UpdatePanel ID="projPanel" runat="server" UpdateMode="Always">
<ContentTemplate>
<asp:Label ID="ProjCount" runat="server" CssClass="label-info" Font-Bold="true" ForeColor="White" Width="300px"/> <%--project counter--%>
</ContentTemplate>
</asp:UpdatePanel>
</div>
I don't know with asp.net, but with a single css :
.label-info{
display : inline-block;
float : left;
}
It appears the part that has
<%--<br />--%>
is breaking the line apart. Once changing that, the CSS bit display: inline-block; will do the trick.
Please use following css property, because <asp:label/> gets rendered as <div>.
div.lable-info{
display:inline;
}

How do I fix the button's position?

<table>
<tr>
<td>
<div style="margin-left: 220px;">
<asp:Button ID="btn1" Text="Edit" CommandArgument='<%#Eval("UserID") %>'
CausesValidation="false" CommandName="Edit" Visible="false" runat="server" />
</td>
</div>
<td>
<div style="margin-left: 370px;">
<asp:Button ID="btn2" Visible="false" Text="Edit" CommandArgument='<%#Eval("UserID") %>'
CausesValidation="false" CommandName="Edit" runat="server" />
</div>
</td>
</tr>
</table>
The problem is when both buttons are made visible dynamically..the second button shifts right wards..how do I fix their position so they appear exactly where I want them ?
[edit]
Do I need to use span or something instead of those divs ? IS there an HTML property that lets u fix a position of an element on page ? How do u do it ? I hv been googling but nothing came up..plz help
[edit 2]
I just added position:fixed in style attribute in the two buttons..when I ran the code again..both buttons didn't even appear!
how do u do it if not even this way ?
[edit 3]
I removed the divs and set both "td's" align property to centre..now the edit buttons are both appearing on the left together :/
Set a fixed width on the columns.
Also you need to fix the ordering of your td and div tags
<table>
<tr>
<td width="200px">
<asp:Button ID="btn1" Text="Edit" CommandArgument='<%#Eval("UserID") %>' CausesValidation="false" CommandName="Edit" Visible="false" runat="server" />
</td>
<td width="200px">
<asp:Button ID="btn2" Visible="false" Text="Edit" CommandArgument='<%#Eval("UserID") %>' CausesValidation="false" CommandName="Edit" runat="server" />
</td>
</tr>
</table>
Will make the column 200px wide, just replace it with whatever width that suits your needs.
Edit:
And well you don't really need the div tags for what you are doing.
