I have a need to programmatically create a RadGrid based on the number of elements from another table.  So I have the following:

foreach (DataRow customerRow in dtDistinctMonitors.Rows)
                //Get Data
                DataRow[] rowData = dtMonitors.Select("tenantID = '" + tenantID + "'");

                //Add Label
                Label lblName = new Label();
                lblName.Text = "Channel: xxxx";
                lblName.Font.Size = FontUnit.Large;

                //Add RadGrid
                RadGrid RadGrid1 = new RadGrid();
                RadGrid1.ID = customerRow["channelID"].ToString();

                //Add RadGrid to the Controls collection of the placeholder

                RadGrid1.DataSource = rowData;
                RadGrid1.MasterTableView.DataKeyNames = new string[] { "monitorID" };
                RadGrid1.AllowPaging = false;
                RadGrid1.MasterTableView.AutoGenerateColumns = false;
                RadGrid1.Skin = "Silk";
                RadGrid1.RenderMode = RenderMode.Lightweight;
                RadGrid1.Width = Unit.Percentage(100);
                GridBoundColumn boundColumn;
                boundColumn = new GridBoundColumn();
                boundColumn.DataField = "monitorName";
                boundColumn.HeaderText = "Monitor Name";
                GridButtonColumn buttonColumn;
                buttonColumn = new GridButtonColumn();
                buttonColumn.Text = "Delete";
                buttonColumn.ButtonType = GridButtonColumnType.LinkButton;
                buttonColumn.HeaderStyle.Width = Unit.Pixel(100);
                buttonColumn.CommandArgument = "monitorID";
                buttonColumn.CommandName = "lnkDelete_Command";

And below I have lnkDelete_Command as:

public void lnkDelete_Command(object sender, CommandEventArgs e)
        using (SqlConnection sqlConn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["stringvalue"].ConnectionString))
            string ID = e.CommandArgument.ToString();

            //DELETE FROM WHERE ID = ID


Yet, when I click on the LinkButton created it doesn't fire.  It doesn't really do anything at all but creates a second instance of the button.  Am I missing something simple here?

Hello Richard,

If you will be creating the grid programmatically, I advise that you review the following articles. The key points to look for in them are:

  • which events you must create the grid in (generally, using Page_Init is the best option, and Page_Load is the latest option)
  • ensure the grid is re-created after each postback
  • the order of setting the column properties and adding the columns to the grid
  • how to add event handlers dynamically (usually handing the ItemCommand event will be easiest as it is likely you will be using it for other tasks and not just the custom command)
  • that you should add the grid to the page at the end of its settings creation

That said, here are the links:
