Programattic GridCheckBoxColumn

[Keith]

I have a radgrid that is entirely created programatically and I'm trying to add a GridCheckBoxColumn.  I want the checkboxes to be editable upon load but they are stuck in read only mode.  I can't figure out how to make them checkable. 

ASPX:

<asp:PlaceHolder ID="phRadGrids" runat="server" />

C#:

RadGrid newGrid = new RadGrid();
newGrid.ID = "grdTesting";
newGrid.MasterTableView.AutoGenerateColumns = false;

GridCheckBoxColumn col_Assign = new GridCheckBoxColumn();
col_Assign.HeaderText = "Assign";
col_Assign.UniqueName = "Assign";
newGrid.MasterTableView.Columns.Add(col_Assign);

phRadGrids.Controls.Add(newGrid);

The checkbox column shows up fine but it's greyed out and cannot be checked.  Is there an easy way to push this into an editable mode on load?

foreach (GridDataItem dataItem in thisGrid.Items)
{
    foreach (GridColumn col in thisGrid.Columns)
    {
        if (col.UniqueName == "Assign")
        {
            CheckBox chkAssigned = (CheckBox)dataItem["Assign"].Controls[0];
            chkAssigned.Enabled = true;
        }
}

This did the trick.  I found it inside another thread about a different topic.
