Dynamic column problem

[Art]

Hello,

I am dynamically adding a GridTemplateColumn to the grid. The column is added as required the first page load but on each following postback I am getting a new empty columm with header "Action". Any Idea?

 protected void Page_Init(object sender, EventArgs e)
        {
   
              var col = this.requestGrid.MasterTableView.Columns.FindByUniqueNameSafe("ActionId");
               
                GridTemplateColumn actionColumn = new GridTemplateColumn();
                this.requestGrid.MasterTableView.Columns.Add(actionColumn);
                actionColumn.ItemTemplate = new ActionTemplate("actionID");                
                
                actionColumn.DataField = "ActionID";
                
                actionColumn.HeaderText = "Action";
               
        }

Hi,

When generating a grid in the Page_Init event handler, grid columns should be added to the Columns collection of the MasterTableView after their attributes are set.

C#:

protected void Page_Init(object sender, EventArgs e)
  {
    GridTemplateColumn actionColumn = new GridTemplateColumn();
    actionColumn.ItemTemplate = new ActionTemplate("actionID");
    actionColumn.DataField = "ActionID";
    actionColumn.HeaderText = "Action";
    this.requestGrid.MasterTableView.Columns.Add(actionColumn);
  }

Thanks,
Shinu
