How to make multiple rows in single cell using GridView - html

here i am facing one task...
In my gridview there are two cols ok, named as user and profile. i need to display profile list related to user in single cell(multiple rows). how do i do that???
This what i tried
<asp:BoundField DataField="UserName" HeaderText="User">
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" />
</asp:BoundField>
<%--<asp:BoundField DataField="ProfileName" HeaderText="Profile">
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" />
</asp:BoundField>--%>
<asp:TemplateField>
<HeaderTemplate>Profile</HeaderTemplate>
<ItemTemplate>
<%#Eval("UserName.ProfileName")%>
</ItemTemplate>
</asp:TemplateField>

You merge the row according to condition. Here is a good example
http://www.codeproject.com/Articles/34337/How-to-merge-cells-with-equal-values-in-a-GridView
public static void MergeRows(GridView gridView)
{
for (int rowIndex = gridView.Rows.Count - 2; rowIndex >= 0; rowIndex--)
{
GridViewRow row = gridView.Rows[rowIndex];
GridViewRow previousRow = gridView.Rows[rowIndex + 1];
for (int i = 0; i < row.Cells.Count; i++)
{
if (row.Cells[i].Text == previousRow.Cells[i].Text)
{
row.Cells[i].RowSpan = previousRow.Cells[i].RowSpan < 2 ? 2 :
previousRow.Cells[i].RowSpan + 1;
previousRow.Cells[i].Visible = false;
}
}
}
}

ASP.NET SQLDataSource SelectParameters default value not working

I wrote a simple ASP.NET form to manage a particular query on my (MySQL) db. Such query is handled by this stored procedure:
CREATE DEFINER=`root`#`localhost` PROCEDURE `noleggio_conducenti`(IN _id_convenzionato INT(10))
BEGIN
IF _id_convenzionato IS NOT NULL THEN
SELECT * FROM
(
SELECT
*
FROM
noleggi AS H
WHERE
id_convenzionato = _id_convenzionato
UNION
SELECT
*
FROM
noleggi AS H
WHERE
id_convenzionato IN (SELECT
id_recipiente
FROM
sosautomotive.transizioni_point
WHERE
id_cedente = _id_convenzionato )
) H
WHERE (H.uscita IS NOT NULL) AND (H.rientro IS NOT NULL);
ELSE
SELECT
*
FROM
noleggi
WHERE (uscita IS NOT NULL) AND (rientro IS NOT NULL);
END IF;
END
As you can see the only parameter can be NULL ... my hope was to use this stored procedure to provide data to the following SQLDataSource object:
<asp:SqlDataSource
ID="_sdsConducenti"
runat="server"
ConnectionString="<%$ ConnectionStrings:sos_db %>"
ProviderName="<%$ ConnectionStrings:sos_db.ProviderName %>"
SelectCommandType="StoredProcedure"
SelectCommand="noleggio_conducenti">
<SelectParameters>
<asp:Parameter Name="_id_convenzionato" Type="Int32" DefaultValue="" ConvertEmptyStringToNull="true" />
</SelectParameters>
</asp:SqlDataSource>
That provides data to a GridView :
<asp:GridView
ID="_gvConducenti"
runat="server"
DataSourceID="_sdsConducenti"
OnSorting="_gvConducenti_Sorting"
OnPageIndexChanging="_gvConducenti_PageIndexChanging"

CommandArgument='<%# Eval("idnoleggio")%>'
CommandName="Link"

</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField HeaderText="Conducente" DataField="conducente" />
<asp:BoundField HeaderText="Via" DataField="conducente_via" />
<asp:BoundField HeaderText="N° Civico" DataField="conducente_num_civico" />
<asp:BoundField HeaderText="CAP" DataField="conducente_cap" />
<asp:BoundField HeaderText="Città" DataField="conducente_residente_in" />
<asp:BoundField HeaderText="Prov." DataField="conducente_residente_in_provincia" />
<asp:BoundField HeaderText="Convenzionato" DataField="convenzionato" />
<asp:BoundField HeaderText="Uscita" DataField="uscita" DataFormatString="{0:dd/MM/yyyy HH:mm}" />
<asp:BoundField HeaderText="Rientro" DataField="rientro" DataFormatString="{0:dd/MM/yyyy HH:mm}" />
<asp:BoundField HeaderText="Tipologia noleggio" DataField="modalita_noleggio" />
</Columns>
</asp:GridView>
of course this form has other fields used to filter the query and those are handled by this couple of functions:

I tested the stored procedure trough MySQL Workbench and I'm sure it works (both with a valid parameter and with NULL).
BUT when I try to use it within the form it works ONLY if the parameter value is provided and when then value is set to NULL (i.e. _sdsConducenti.SelectParameters["_id_convenzionato"].DefaultValue = null) the query did not provide any data (while it should retrieve a large number of records).
Where did I fail? How can I check if the NULL value is correctly set as the parameter value before calling the stored procedure?
Full code available here.
Try specifying below property in SQLDataSource definition -
CancelSelectOnNullParameter="false"
And it is described as
true if a data retrieval operation is canceled when a parameter
contained in the SelectParameters collection evaluated to null;
otherwise, false. The default is true
The similar problem is explained here -
Set SqlDataSource parameter to null

Show/Hide Button depending on stored procedure return value

I'd like to get some help on an issue I'm having. I have a stored procedure that returns a dataset to fill a datagriview. One of the data grid's columns contains 2 manually set buttons, 'View' & 'Add'. These buttons open up a new popup window which displays extra information etc. I would like to be able to hide a 'View' button if 1 of the returned parameter's, POCount, count is equal to 0. i.e. there is nothing to view for that row. What is the best way to make this happen.
My stored procedure is
SELECT PM.ProjectCode,
PM.ProjectDesc,
PM.Active,
PM.Chargeable,
(SELECT COUNT(*) FROM POMaster PO WHERE PO.ProjectCode = PM.ProjectCode) AS POCount
FROM PROJECTMASTER PM
Front End Code
<asp:TemplateField HeaderText="P.O. Number" ItemStyle-Wrap="false" >
<ItemTemplate>
<asp:LinkButton ID="linkPONumber" runat="server" Text="View" CssClass="buttonStyle" OnClick="LinkPONumber_Click" CommandArgument='<%# Eval("ProjectCode") + ";" + Eval("ProjectDesc") %>' ></asp:LinkButton>

</asp:TemplateField>
Code Behind
private void BindGrid()
{
DSProjectDetails = objProjectMasterBL.GetProjectDetails();
GvProject.DataSource = DSProjectDetails;
GvProject.DataBind();
}

{
SqlProcedureName = "USP_GetProjectListWithPO";
SqlConnectionObject = DBConnection.InitializeConnection(SqlConnectionObject);
dsrepeater = SqlHelper.ExecuteDataset(SqlConnectionObject, CommandType.StoredProcedure, SqlProcedureName);
return dsrepeater;

catch (Exception ex)

Apologies if I've sent the wrong sections of code, still residing in the noob ranks
You can use the Visible property of Link Button:-
<asp:LinkButton ID="linkAddPO" runat="server" Text="Add" CssClass="buttonStyle"
OnClick="LinkAddPO_Click" Visible='<%# Convert.ToInt32(Eval("POCount")) == 0 %>'
CommandArgument='<%# Eval("ProjectCode") + ";" + Eval("ProjectDesc") %>'>
</asp:LinkButton>
Whenever your SP returns POCount as 0, you LinkButton will be hidden.

Validate dynamically created fields when one is changed

I have a program that dynamically creates various text boxes / drop down lists. I am trying to figure out how to validate these fields only when one is changed. Basically if someone entered a date in the text box then I need the program to validate that the drop down list was changed or vice versa. If there are no changes to both fields then it should not validate. Any help would be extremely appreciated. Here is the code:
<asp:TemplateField HeaderText="ValidatedDate" SortExpression="ValidatedDate">
<EditItemTemplate>
<asp:TextBox ID="txtValDate" Width="100px" MaxLength="10" runat="server" AutoPostBack="true"
Text='<%# Bind("ValidatedDate","{0:MM/dd/yyyy}") %>'></asp:TextBox>
<asp:RegularExpressionValidator ValidationGroup="g1" ID="RegularExpressionValidator10"
runat="server" ControlToValidate="txtValDate" Display="None" ErrorMessage="Validated Date: ##/##/####"
ValidationExpression="\d{1,2}/\d{1,2}/\d{4}"></asp:RegularExpressionValidator>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="lblValidatedDate" runat="server" Text='<%# Bind("ValidatedDate","{0:MM/dd/yyyy}")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="ProductStatus" SortExpression="ProductStatusDescription">
<EditItemTemplate>
<asp:DropDownList ID="DropDownList4" runat="server" DataSourceID="SqlDataSource6" AutoPostBack="true"
DataTextField="StatusDescription" DataValueField="StatusID" SelectedValue='<%# Bind("Status") %>'>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="lblProductStatus" runat="server" Text='<%# Bind("ProductStatusDescription")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
My apologies, the code can be a bit confusing without the correct context.
ebyrob, thank you for your help. I figured it out however and it works beautifully. Here is the code that fixed it all:
protected void AddError(string errorMessage)
{
cstValidate.IsValid = false;
cstValidate.ErrorMessage = errorMessage;
cstValidate.EnableClientScript = false;
}
protected void GridView2_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
TextBox txtValidatedDate = GridView2.Rows[e.RowIndex].FindControl("txtValDate") as TextBox;
DropDownList ddlStatusCompare = GridView2.Rows[e.RowIndex].FindControl("dropdownlist4") as DropDownList;
if (txtValidatedDate.Text == string.Empty && ddlStatusCompare.SelectedValue == "1")
{
AddError("Please enter a Validated Date");
e.Cancel = true;
}
else if (txtValidatedDate.Text != string.Empty && ddlStatusCompare.SelectedValue == "0"
|| txtValidatedDate.Text != string.Empty && ddlStatusCompare.SelectedValue == "99")
{
AddError("Please remove the Validated Date");
e.Cancel = true;
}
if (!e.Cancel)
Helpers.LogChanges(GridView2, e, _employeeID, "SaleProducts");
}

Partial page updating using update panel

I am creating "edit my profile page" where I have some text boxes and drop down lists.I have a requirement such that when I select a value in my first drop down, the second drop down should fill. But this is not happening.
<asp:UpdatePanel runat="server" ID="updatepanel1" UpdateMode="Conditional">
<ContentTemplate >
<asp:Label runat="server" Id="lbljobIndus" Text="Preferred Job Industry" Font-Names="Calibri" Font-Size="Small" ForeColor="Black"></asp:Label>
<span style="color: black; font-family: Calibri; font-size: small">:</span>
<asp:Label runat="server" ID="lblPreferredJobIndustry" Font-Names="Calibri" Font-Size="Small" ForeColor="Black"></asp:Label>
<asp:DropDownList ID="tbPreferredJobIndustry" runat="server" Height="19px" OnSelectedIndexChanged="ddlTargetedIndustry_SelectedIndexChanged">
<asp:ListItem Selected="True" Value="-1">--Select Industry--</asp:ListItem>
<asp:ListItem Value="1">Administration</asp:ListItem>
<asp:ListItem Value="2">Hospital/HealthCare</asp:ListItem>
<asp:ListItem Value="3">Medical Transcription</asp:ListItem>
</asp:DropDownList>
<br />
<br />
<br />
<asp:Label runat="server" ID="lblJobCat" Text="Preferred Job Category" Font-Names="Calibri" Font-Size="Small" ForeColor="Black"></asp:Label>
<span style="color: black; font-family: Calibri; font-size: small">:</span>
<asp:Label runat="server" ID="lblJobCategory" Font-Names="Calibri" Font-Size="Small" ForeColor="Black"></asp:Label>
<asp:DropDownList ID="tbJobCategory" runat="server">
<asp:ListItem Selected="True" Value="-1">-Position Category-</asp:ListItem>
</asp:DropDownList>
<br />
<br />
</ContentTemplate>
</asp:UpdatePanel>
This is the code to populate the second drop down list :-
protected void ddlTargetedIndustry_SelectedIndexChanged(object sender, EventArgs e)
{
DataSet ds = new DataSet();
SqlDataAdapter myda = new SqlDataAdapter("Select s_CategoryName,FK_TargetedIndustryID FROM [OfinityJobSearch].[dbo].[tm_JobCategory] where FK_TargetedIndustryID='" + tbPreferredJobIndustry.SelectedItem.Value + "'", con);
myda.Fill(ds);
tbJobCategory.DataSource = ds;
tbJobCategory.DataValueField = "FK_TargetedIndustryID";
tbJobCategory.DataTextField = "s_CategoryName";
tbJobCategory.DataBind();
tbJobCategory.Items.Insert(0, new ListItem("--Select Job Category--", "0"));
}
I used update panel so that the values in other text boxes will not get cleared on the post back. But right now, I think the post back is not happening.Can you please check my code and tell me where the error is?
Set AutoPostBack= true for the first ddl
U can use AjaxToolkit CascadingDropDown it's very helpful and useful. But in case of CascadingDropDown u need additional service.
<ajaxToolkit:CascadingDropDown ID="CDD1" runat="server"

updatepanel does not trigger repeater itemcommand

I just want to trigger the LinkButton in a repeater which has a OnItemCommand. But the page do post back. Here is my code:
<asp:UpdatePanel ID="recommendedAdvertsUpPnl" runat="server">

</asp:Repeater>
</div>
<div class="RecommendedAdverts_List">
<asp:Repeater ID="rpRecommendedAdvertList" runat="server" OnItemDataBound="rpRecommendedAdvertList_ItemDataBound">
<HeaderTemplate>
<ul class="content_recommended">
</HeaderTemplate>
<ItemTemplate>
<%# Container.ItemIndex % 4 == 0 ? "<li><div class=advertContainer>": String.Empty%>
<div class="advertPanel">
<div class="rAdvPanel">

</asp:Repeater>
</div>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="rpRecommendedAdvertFacultyList" EventName="ItemCommand" />
</Triggers>
</asp:UpdatePanel>
There is no problem except for triggering. Here is the my server side code:
protected void rpRecommendedAdvertFacultyList_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
{
AdvertFacultyInfo item = (AdvertFacultyInfo)e.Item.DataItem;
LinkButton lbtnAdvertFaculty = (LinkButton)e.Item.FindControl("lbtnAdvertFaculty");
lbtnAdvertFaculty.Text = item.Faculty.name;
}
}
protected void rpRecommendedAdvertFacultyList_ItemCommand(object source, RepeaterCommandEventArgs e)
{
switch (e.CommandName)
{
case "selectFaculty":
List<AdvertFacultyInfo> advFacultyInfoList = EntitiyProvider.GetAdvertFacultyInfoListByFacultyId(Convert.ToInt32(e.CommandArgument));
List<Advert> selectedList = new List<Advert>();
foreach (AdvertFacultyInfo item in advFacultyInfoList)
{
Advert currentAdv = this.recommendedAdvertList.FirstOrDefault(i => i.id == item.advertId);
if ( currentAdv != null)
{
selectedList.Add(currentAdv);
}
}
rpRecommendedAdvertList.DataSource = selectedList;
rpRecommendedAdvertList.DataBind();
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "temp", "<script type='text/javascript'>$('.content_recommended').quickPager()</script>", false);
break;
default:
break;
}
}
I have also tried this code: But it gives error like lbtnAdvertFaculty could'nt find
<asp:AsyncPostBackTrigger ControlID="lbtnAdvertFaculty" EventName="Click" />
I have researched a lot of document written about this problem but I could not find useful examples and solution.
Best Regards.
