You can handle the GridView_RowBound event and make the cell of which the column need to hide invisible like followin

protected void gdvAgency_RowDataBound(object sender, GridViewRowEventArgs e)
{
e.Row.Cells[1].Visible = false;
}

Here my first column was select button and second one agency Id I am hiding autoid column here.

Thanks alot.

I was using the ObjectDataSource with my gridview.

I was tring to 'hide' the visibility of the gridview column after databound ... that was not working.

I was just about to give up on using the ObjectDataSource and do the databinding in code.

Your solution works great.

Thanks alot.

//Sorry some of the code was missing
protected void ExpandCol(object sender, EventArgs e)
{
GridView1.Columns[0].Visible = true;

for (int i = 0; i < GridView1.Rows[i].Cells.Count; i++)
{
for (int j = 0; j < GridView1.Rows[i].Cells.Count; j++)
{
GridView1.Rows[i].Cells[j].Visible = true;
}
}
}

Thanks for your solution.
Another approach ist to databind first and then hide columns in the code behind page
...
GridView1.DataBind();
GridView1.Columns[0].Visible = false;
...
//function (codebehind) which shows the data
//called from any asp.net-control)
protected void ExpandCol(object sender, EventArgs e)
{
GridView1.Columns[0].Visible = true;
}

on page load event

myGridView.Column[0].Visisble = false;

Row Created event will be called upon each row.. however there are some cases where we may need to use this event

Nelson,
Select the GridView control on you page. Bring up the properties window. Click on the "Events" botton (looks like flash/thunder symbol). You will get a list of events from where you double-click "RowCreated" event.

Further, since you are new to ASP.NET, I suggest you take some help from your colleagues.

I kept getting an Argument Out of Range exception so I put the code in a Try block and it solved all my problems. Thanks!
