GridView

[bbawa1]

I have a GetData methd which is returning a table using
sqldataadapter. I bound that datasource with GridView but now I want
to invisible Gridview's first column but it gives me following error
although I have 5 columns in my datatable.

Index was out of range. Must be non-negative and less than the size of
the collection.
Parameter name: index

GridView1.DataSource = GetData();

GridView1.DataBind();
GridView1.Columns[1].Visible = false;
Thanks for help me in advance

What do you get back when you call:

GridView1.Columns.Count();

Yes. Count = 0 . But I don't know why

Hi there,

Autogenerated columns are not included in the Columns collection. You have to
handle RowDataBound event instead:

protected void GridView1_RowDataBound(object sender,
GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow ||
e.Row.RowType == DataControlRowType.Header ||
e.Row.RowType == DataControlRowType.Footer)
{
e.Row.Cells[1].Visible = false;
}
}

hope this helps
