I have the following Gridview which I am trying to pass a search parameter, to update the results based on that search -
<ContentTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Search" />
<asp:Label ID="Label1" runat="server" Text="Grid not refreshed yet."></asp:Label><br />
<asp:Label ID="Label4" runat="server" Text="(Grid Will Referesh after Every Second)"Font-Bold="true"></asp:Label>
<br /><br />
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:MyDbConn %>"
SelectCommand="SELECT * FROM [table] WHERE BODYTEXT LIKE='"+TextBox1.text+"></asp:SqlDataSource>
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
BackColor="Black" DataSourceID="SqlDataSource1" Font-Names="Arial Black"
Font-Size="Small" ForeColor="White" Height="650px" Width="930px">
</asp:GridView>
</ContentTemplate>
However I cant seem to get the SQL statement to accept the TextBox1 text that the user is entering, how can I resolve this?
You must do this in code behind.
SqlDataSource1.SelectCommand = "SELECT * FROM [table] WHERE BODYTEXT LIKE='"+TextBox1.Text;
You can do this when clicking on the search button.

When I click to edit the txtHours box, I get this error when I click the submit button:
Procedure or function UpdateWish has too many arguments specified.
I'm fairly new to all this so I've probably made a simple error somewhere. It's code which was written for me and I have changed it for a different application. Should all work if I can sort this error. I use ASP.NET, VB.Net and SQL Server. There is no code in the VB file which should affect this so I haven't included that. Any help appreciated.

SQL Server stored procedure:

#wishID int,
#dailyHours decimal(10,2)
AS
BEGIN
SET NOCOUNT ON;
UPDATE tblWishes
SET dailyHours = #dailyHours
WHERE wishID = #wishID
END
As per your code, it looks perfect for passing 2 update parameter and in stored procedure also there is 2 parameters.
Also for select and delete working fine with CommandType.StoredProcedure?
Otherwise, you should first try without stored procedure as per the following way.
Removing UpdateCommandType="StoredProcedure" and set update query in UpdateCommand
Code:
<asp:SqlDataSource ID="DSMyWishes" runat="server"
ConnectionString="<%$ ConnectionStrings:DBConnectionString %>"
DeleteCommand="RemoveWish" DeleteCommandType="StoredProcedure"
SelectCommand="SelectFullWishesByAccount"
SelectCommandType="StoredProcedure"
UpdateCommand="UPDATE tblWishes SET dailyHours = #dailyHours WHERE wishID = #wishID">

How to set my columns like above format?
Please Help.
I am using ASP.net and at some point I have a gridview that doesn't show up in my browser when I debug my project. On that same page do I use a textbox and that one does show up.
This is the HTML.
<%# Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/MasterPages/SvShop.Master" CodeBehind="Mijnoverzicht.aspx.vb" Inherits="SvShop.Mijnoverzicht" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<h1>Mijn Artikelen</h1>
<table>
<tr>
<td>Email</td>
<td>
<asp:TextBox ID="txtMijnEmail" runat="server" CssClass="tekstvak" Width="190px"></asp:TextBox>
</td>
</tr>
</table>
<div class="OverzichtMijn">
<asp:GridView ID="GridViewMijn" runat="server" AllowPaging="True" AutoGenerateColumns="False" DataSourceID="MijnDataSource" AllowSorting="True" Width="845px">
<Columns>
<asp:BoundField DataField="ArtikelBeschrijving" HeaderText="Beschrijving" SortExpression="ArtikelBeschrijving" />
<asp:BoundField DataField="ArtikelPrijs" HeaderText="Prijs" SortExpression="ArtikelPrijs" />
<asp:BoundField DataField="ArtikelAankoopdatum" HeaderText="Aankoopdatum" SortExpression="ArtikelAankoopdatum" />
<asp:BoundField DataField="ArtikelTekoopgezet" HeaderText="Tekoopgezet" SortExpression="ArtikelTekoopgezet" />

<asp:BoundField DataField="GebruikersGSM" HeaderText="GSM" SortExpression="GebruikersGSM" />
</Columns>
<EditRowStyle CssClass="GridViewEditRow" />
</asp:GridView>
<asp:SqlDataSource ID="MijnDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:SvShopInternString %>" ProviderName="<%$ ConnectionStrings:SvShopInternString.ProviderName %>" SelectCommand="SELECT tblArtikel.ArtikelBeschrijving, tblArtikel.ArtikelPrijs, tblArtikel.ArtikelAankoopdatum, tblArtikel.ArtikelTekoopgezet, tblGebruiker.GebruikersNaam, tblGebruiker.GebruikersVoornaam, tblGebruiker.GebruikersEmail, tblGebruiker.GebruikersGSM FROM ((tblArtikel INNER JOIN tblGebruiker ON tblArtikel.GebruikersID = tblGebruiker.GebruikersID) INNER JOIN tblRubriek ON tblArtikel.RubriekID = tblRubriek.RubriekID) WHERE (tblGebruiker.GebruikersEmail = '#Email')"></asp:SqlDataSource>
</div>
</asp:Content>
This is the browser view.
The problem should be in this line of code.
<asp:SqlDataSource ID="MijnDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:SvShopInternString %>" ProviderName="<%$ ConnectionStrings:SvShopInternString.ProviderName %>" SelectCommand="SELECT tblArtikel.ArtikelBeschrijving, tblArtikel.ArtikelPrijs, tblArtikel.ArtikelAankoopdatum, tblArtikel.ArtikelTekoopgezet, tblGebruiker.GebruikersNaam, tblGebruiker.GebruikersVoornaam, tblGebruiker.GebruikersEmail, tblGebruiker.GebruikersGSM FROM ((tblArtikel INNER JOIN tblGebruiker ON tblArtikel.GebruikersID = tblGebruiker.GebruikersID) INNER JOIN tblRubriek ON tblArtikel.RubriekID = tblRubriek.RubriekID) WHERE (tblGebruiker.GebruikersEmail = '#Email')"></asp:SqlDataSource>
The parameter
#Email
gets his value from the textbox above with this code:
Protected Sub txtMijnEmail_TextChanged(sender As Object, e As EventArgs) Handles txtMijnEmail.TextChanged
MijnDataSource.SelectCommand.Replace("#Email", txtMijnEmail.Text)
GridViewMijn.DataBind()
End Sub
Overkill - just add a Control Parameter to the SelectParameters:
<asp:SqlDataSource ID="MijnDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:SvShopInternString %>"
ProviderName="<%$ ConnectionStrings:SvShopInternString.ProviderName %>"
SelectCommand="SELECT <snip> WHERE (tblGebruiker.GebruikersEmail = '#Email')">
<SelectParameters>
<asp:ControlParameter
ControlID="txtMijnEmail"
PropertyName="Text"
Name="Email">
</asp:ControlParameter>
</SelectParameters>
</asp:SqlDataSource>
And obviously make sure your Select command returns a dataset when a valid email is provided.
Also consider temporarily setting GridViewMijn.ShowHeader="true" and GridViewMijn.EmptyDataText="No Data returned" for debugging purposes
I am trying to add a DropDownList into the DataGrid so the location column can be easily changed. I am getting an error with TemplateField, itemtemplate, label and DropDownList. I get the build error:

<asp:DataGrid runat="server" CssClass="tblResults" OnItemDataBound="dgList_ItemCreated" AllowSorting="true" OnSortCommand="dgTrailer_Sort" ID="dgTrailers" DataKeyField="ID" AutoGenerateColumns="false">

<asp:BoundColumn DataField="TrailerOwner" HeaderText="Owner" SortExpression="TrailerOwner"></asp:BoundColumn>
<asp:BoundColumn DataField="TrailerMake" HeaderText="Trailer Make" SortExpression="TrailerMake"></asp:BoundColumn>
<asp:TemplateField HeaderText="Trailer Location">

</asp:TemplateField>
<asp:BoundColumn DataField="Year" HeaderText="Year" SortExpression="Year"></asp:BoundColumn>

</asp:DataGrid>
TemplateField, itemtemplate, label and DropDownList all have green lines under them and which means its not a known element.
You should use TemplateColumn, when it comes to DataGrid as it is inherited from System.Web.UI.WebControls.DataGridColumn.
TemplateField is inherited from System.Web.UI.WebControls.DataControlField, which make sense with GridView.
I have a list view to show products with prices. I put an updatePanel in ItemTemplate.
When I Click the button in contentTemplate, the Eval fields do not update, By definition the
update panel do a partial post back but it does not reflect database changes.
<ContentTemplate>
<asp:ImageButton ID="productPic" runat="server" Height="270" Width="202" ImageUrl='<%# Eval("ImageUrl") %>' />
<asp:Table ID="ColorTable" runat="server" EnableViewState="true"></asp:Table>
<asp:Button ID="Button1" runat="server" Text="Button" />
<asp:Literal ID="LitProductId" runat="server" Text='<%# Eval("ProductId") %>' EnableViewState="true"></asp:Literal>
<asp:Label ID="Label2" runat="server" Text='<%# Eval("Name") %>' Font-Size="8"
Font-Bold="False" Font-Names="tahoma" />
<br />
<asp:Label ID="Label3" runat="server" Text='<%# Eval("Price","{0:0,0}") %>' Font-Size="8" Font-Bold="False" Font-Names="tahoma"
Font-Strikeout='<%# Eval("DiscountedPrice")!=DBNull.Value %>' />
<br />
<asp:Label ID="Label4" runat="server" Text='<%# Eval("DiscountedPrice","{0:0,0}") %>' Font-Size="10" Font-Bold="True" Font-Names="tahoma" ForeColor="Red"
Visible='<%# Eval("DiscountedPrice")!=DBNull.Value %>' />
<br />
</ContentTemplate>
</asp:UpdatePanel>

I appreciate any help.
It's because you are dynamically adding them in. When you post back, it loses that state and if you aren't adding them back in at that point (i.e. saving them to viewstate and adding them back in on load), it no longer knows they exist.
I found the solution.
If you want to use update panel inside a listview, you should bind the data source in code - page load.
ListView1.DataSource = new ProductFacade().GetCat3ProductListSpec(cat3Id);
ListView1.DataBind();
When you use sqlDataSource attribute, the update panel does not function as you expect.
