How To rename Column in Grid where AutoGenerateColumns=True

[johnson lim]

HI,
I have a grid that serves multi purpose. The data pass to the grid is dynamic. And hence i set AutoGenerateColumns="True"
I need to change the column header text to different different text in  different situation based on column index.
All the resources found online manage to change the header text of a particular column based on column Unique name.

Does anyone has idea on this?
Help Please!!

Hello Johnson,

protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        foreach (GridColumn column in RadGrid1.MasterTableView.AutoGeneratedColumns)
        {
            if (column.OrderIndex == 1)
            {
                column.HeaderText = "Your Text";
            }
        }
    }

Thanks,
Jayesh Goyani

Hi Jayesh, is it possible to set it in  ItemDataBound event?
 I had already use NeedDataSource event.
The use of PreRender event seems not pratical, because this event will be execute whenever there is a post back.

Hi Johnson,

You can try using ItemDataBound with a check if(e.Item is GridHeaderItem). However, the control rendered there depends on whether you have sorting enabled, so you should have this in mind when accessing it.

Also, you could use the ColumnCreated server event. It fires for each autogenerated column and you could modify the column properties there.

For more information on working with autogenerated columns, see this link:
