Capture SelectedIndexChanged in RadGrid

[Pat]

How do I setup RadGrid.SelectedIndexChanged programatically?  I get the following error

"No overload for 'RadGrid1_SelectedIndexChanged' matches delegate 'System.EventHandler' "

I am trying to capture when the user clicks the "Go" button

:
:
:
RadGrid RadGrid1 = new RadGrid();

RadGrid1.DataSourceID = "SqlDataSource1";

RadGrid1.MasterTableView.DataKeyNames = new string[] { "Jobnumber" };

RadGrid1.Skin = "Default";

RadGrid1.Width = Unit.Percentage(100);

RadGrid1.PageSize = 5;

RadGrid1.AllowPaging = true;

RadGrid1.AllowSorting = true;

RadGrid1.AutoGenerateColumns = false;

RadGrid1.MasterTableView.PageSize = 15;

RadGrid1.GridLines = GridLines.Both;

RadGrid1.SelectedIndexChanged +=new EventHandler(RadGrid1_SelectedIndexChanged);  // Not work Generates error
:
:
:
       GridButtonColumn buttonColumn = new GridButtonColumn();
       buttonColumn.HeaderText = "Select File";
       buttonColumn.CommandName = "Select";
       buttonColumn.ButtonType = GridButtonColumnType.PushButton;
       buttonColumn.Text = "Go";
       buttonColumn.ItemStyle.HorizontalAlign = HorizontalAlign.Center;

       RadGrid1.MasterTableView.Columns.Add(buttonColumn);
:
:
:
:



    protected void RadGrid1_SelectedIndexChanged(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "Select")
        {
 
        }

    }

Hello Pat,

I amo not quite sure about your exact requirement. The RadGrid SelectedIndexChanged event  fired when a different item is selected in a data listing control between posts to the server.
 If you want to check for the commandName the better approach is to attach ItemCommand and there check for the command name.
C#:

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
   {
     if (e.CommandName == "Select")
       {
         //your code.
       }
   }

Thanks,
Shinu.
