RadGrid headers disappearing on select command

[Zachary]

I have a RadGrid that is being configured dynamically at run time. The purpose is create a custom grid based on an arbitrary sql query. I'm adding a gridbuttoncolumn at runtime that has a select command. When this button is clicked, all the select links disappear and the column headers disappear as well. Any thoughts on what this issue may be?

As a follow up, my Select button is not firing off  the selectedindexchanged. The itemcommand event is firing, but the CommandName property is an empty string.

here is the code I'm using to set up my grid:

RadAjaxManager1.AjaxSettings.AddAjaxSetting(DropDownList1, RadGrid1);
RadAjaxManager1.AjaxSettings.AddAjaxSetting(RadGrid1, RadGrid1);
RadAjaxManager1.AjaxSettings.AddAjaxSetting(RadGrid1, Label1);
Query q = query;

RadGrid1.MasterTableView.Columns.Clear();
RadGrid1.MasterTableView.DataKeyNames = GetPKArray(q.PrimaryKeys);

RadGrid1.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric;
RadGrid1.AutoGenerateColumns = false;

GridButtonColumn col = new GridButtonColumn();
col.CommandName = "Select";
col.Text = "Select";
RadGrid1.MasterTableView.Columns.Add(col);

foreach (QueryColumns qCol in q.QueryColumns)
{
    GridBoundColumn bCol = new GridBoundColumn();
    bCol.HeaderText = qCol.ColumnName.Replace("[", "").Replace("]", "");
    bCol.DataField = qCol.ColumnName;

    RadGrid1.MasterTableView.Columns.Add(bCol);
}

I have to run this code everytime the grid is rebound or I get the Columns full of "System.Data.DataRowView"

So it appears I have to run Rebind() on every postback. Can someone telerik confirm if this is the intended behavior for this control?

Hello Zachary,

If you have declared RadGrid in the ASPX page and use the Page_Load event handler to adding columns to grid, then the columns should be added to the corresponding collection first, before the values for their properties are set.

C#:

GridButtonColumn col = new GridButtonColumn();
RadGrid1.MasterTableView.Columns.Add(col);
col.CommandName = "Select";
col.Text = "Select";

Please check out the following documentation.
