How to hide column of DataGrid

Question

I am making a web part in which I am using System.Web.UI.WebControls.DataGrid control.
It's AutoGenerateColumns property is set to TRUE.
I am trying to hide a column at run time. I have written the following code on this controls ItemCreated event but it only works if I e.Item.Cells[0] and it doesn't work for any other value for e.g. e.Item.Cells[1] and e.Item.Cells[6].
There are 9 columns in my DataGrid control.
Code
protected void grd1_ItemCreated(object sender, DataGridItemEventArgs e)
{ e.Item.Cells[0].Visible = false; //works fine
e.Item.Cells[1].Visible = false; //gives error e.Item.Cells[2].Visible = false; //gives error
Error
Specified argument was out of the range of valid values.
Parameter name: index

Answer 1

Hi Frank,
You can try something similar to the below in 'RowCreated' event Instead
protected void gridView_RowCreated(object sender, GridViewRowEventArgs e)
e.Row.Cells[1].visible =false;
OR I would say hiding column is not something that is to be done at row level, so you can hide columns outside any of the grid view event after binding.
e.g.
gridview1.columns[1].visible=false;
I am using DataGrid control in which there is no RowCreated event.
I have tried second approach but it also doesn't work.
