Using Multiple ExpandCollapse Buttons

[Troy]

I have a row in a RadGrid that contains three buttons:

<asp:Button ID="Button1" CommandName="ExpandCollapse" CommandArgument="1" Text="Button 1" runat="server" />
<asp:Button ID="Button2" CommandName="ExpandCollapse" CommandArgument="2" Text="Button 2" runat="server" />
<asp:Button ID="Button3" CommandName="ExpandCollapse" CommandArgument="3" Text="Button 3" runat="server" />

In my code-behind, I have the following code:

protected void RadGrid_ItemCommand(object sender, GridCommandEventArgs e)
{
    if ((e.CommandName == RadGrid.ExpandCollapseCommandName) && !e.Item.Expanded)
    {
        // Do stuff here...
    }
}

When I click on a button for the first time, I have a NestedViewTemplate that gets shown. How do I keep the NestedViewTemplate open if I click a different button in the same row? For example, I click button 1 to open the NestedViewTemplate and then I click button 2 to keep the NestedViewTemplate open while showing different data.

Hello,


One suggestion to accomplish this is setting different CommandNames for buttons and explicitly expanding the item based on the CommandName set.

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName == "button1" && !e.Item.Expanded)
    {
        e.Item.Expanded = true;
    }
      . . .
 }

Mark-up:

<telerik:GridTemplateColumn HeaderText="buttons">
          <ItemTemplate>
              <asp:Button ID="Button5" CommandName="button1" CommandArgument="1" Text="Button 1"
                  runat="server" />
                     .   .   .

That works. I found that e.Cancel = true also works. Thank you.
