C# - BindData To ITemplate For GridView In Code Behind?
May 8, 2010
How do I programmatically bind data to a custom item template column for a GridView? So far, I've done something similar to this:
TemplateField foo = new TemplateField();
foo.ItemTemplate = new bar();
this.GridView1.Columns.Add(foo);
where bar is like this:
[code]....
But ITemplate doesn't contain any kind of data binding properties to implement, and the TemplateField class doesn't seem to have any either...
What do I do?
Edit: The other half is being able to handle the updates to get back to the original datasource. If I just handle the rowupdate events, I don't see my TemplateColumn in the oldvalues/newvalues lists.

I've added an ITemplate to Telerik's RadGrid control called SearchMenuTemplate ala:
[code]...
And the Template class looks something like (mandatory override methods like createchildcontrol have been omitted for brevity):
[ParseChildren(true)]
class searchBar : CompositeControl, INamingContainer
{
public string rbStartsWithText { get; set; }
}
Now, in the source control window the RadGrid control sees the Template. But rbStartsWithText isn't an attribute on the node.
I want to see something like this (note: abs prefix is registered in the markup):
<abs:AbsRadGrid ID="rg" runat="server">
<SearchMenuTemplate rbStartsWithText="Starts With" />
</abs:AbsRadGrid>
Instead rbStartsWithText is throwing a green squiggly and telling me it's not a valid attribute of SearchMenuTemplate.

I want to have a control with template supporting so I can put a control on it and I can access them just by their name( just the way Updatepanles do)for instance:
<uc1:FramePanel ID="FramePanel1" runat="server">
<MessageTemplate>
<asp:Button ID="Button1" runat="server" Text="Button"></asp:Button>
</MessageTemplate>
</uc1:FramePanel>
and the in my code could access Button1 like that:
Button1.Text="dsdsdsds";
for now I can access it using find control and Im not happy with it
if you look at updatepanel you can access its control directly
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:Button ID="Button1" runat="server" Text="Button"></asp:Button>
</ContentTemplate>
</asp:UpdatePanel>
ucan access button1 just easily:
Button1.Text="dsdsdsds";

I've created a custom control in ASP.NET for showing a pop-up message box. In my MessageBox class, I have a Content property as ITemplate like the following:
[PersistenceMode(PersistenceMode.InnerProperty)]
[TemplateContainer(typeof(MessageBoxContent))]
[TemplateInstance(TemplateInstance.Single)]
public ITemplate Content { get; set; }
I used my custom control in my page like this:
<cc1:MessageBox ID="MessageBox1" runat="server">
<Content>
<asp:Button Text="Save" runat="server" ID="B_Save" />
</Content>
</cc1:MessageBox>
Even I set the the Content property's TemplateInstance to Single, I still can't have access to the Button control.
All I want to do is to handle the click event of the button. When I assign an event handler to the button control and run the project, it throws a NullReferenceException.

On the RowDataBound event of a gridview I am setting the name of the HtmlInputRadioButton inside the GridViewRow. The problem is that asp.net automatically makes the name unique therefore ungrouping the radio buttons.
Is there a way that I disable this?
Edit - Here's how I am setting the name:
[code]....
Due to the numbers "106" and "107" in the name of the respective radiobuttons it ungroups them.

I have created a gridview in code behind (as in its not physically present on the page). I want to know how to call it's rowdatabound event - as data is being bound to it. There happens to be a Gv.RowDataBound function, but how do I use it? (I want the same functionality as what the asp:gridview control has for its onrowdatabind attribute...)
GridView Gv = new GridView();
Gv.AutoGenerateColumns = false;
BoundField one = new BoundField();
one.DataField = "one";

I am using Visual Web Developer Express with VB.net and have a website with 2 pages in them called "Tables.aspx" and "Variables.aspx". On the Tables page the user is required to enter a variable name in to a texbox, which I want then to take the user to the Variables page and have the gridview display the sql result. In behind the search button on the "Tables.aspx" page I have the following code.
Code:
' Search button code
Dim search As Char
Search = CChar(txtSearch.Text)
If Search = "" Then
MsgBox("You cannot leave this field blank.")
[code]....
On the "Variables.aspx" page I had decided to use data readers which brought up only one of the columns however I realised using data readers would mean I would have to individually position each textbox which I am not sure how to do.
Basically what I would like to know is how I do get the result of sql= "SELECT dbo.NILS_tables.Table_ID, dbo.NILS_variables.Variable_Name, dbo.NILS_ variables.Variable_Description FROM dbo.NILS_variables JOIN dbo.NILS_tables ON dbo.NILS_tables.Table_ID = dbo.NILS_variables.Table_ID WHERE dbo.NILS_tables.Table_Name LIKE '%' OR dbo.NILS_tables.Table_Description LIKE '%' " on to a gridview on the "Variables.aspx" page? NB the code for the search button is stored in the code behind file on the "Tables.aspx" page.

Dim Application = From AL In db.AnnualLeave _
Where AL.Approval <> True _
Select LeaveID, EmpID, Name
GridView3.DataSource = Application
GridView3.DataBind()
after calling `GridView3.DataBind(), why do i still get Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.
at this line of code GridView3.Columns(1).Visible = False yet the grid has rows and more than 2 columns. i found a thread about similar problem here [URL] Note that the Gridview columns have NOT been defined at design time.
