hideColumn gives error.

[Sneha]

Microsoft JScript runtime error: 'this.get_columns()[...]' is null or not an object is the error if I try to hide a column and then bind the grid,

The binding is on the clientside.

Hello Sneha,

You can try the following code snippet in PreRender event to hide the columns and then Rebind the grid:

protected void gvCktMap_PreRender(object sender, EventArgs e)
   {
       gvCktMap.MasterTableView.GetColumn("sid").Visible = false;
       gvCktMap.MasterTableView.GetColumn("customername").Visible = false;
       gvCktMap.MasterTableView.GetColumn("marketname").Visible = false;
       gvCktMap.Rebind();
   }

All the best,

Hi Maria,

Thanks!
Acutally I was looking for a solution that I can do in javascript writing serverside code is the last thing I'd have to do
