How to add new column to asp.net gridview where columns are autogenerated?

Question

How to add new hyperlink column to an asp.net gridview where columns are autogenerated? The columns are not predefined in the gridview.

Answer 1

Just add your column definition the section of the gridview. Your auto-generated columns should show up to the left of this one.

<asp:gridview AutoGenerateColumns="true" ... >
    <columns>
        <asp:hyperlink ... />
    </columns>
</asp:gridview>

Answer 2

I find that autogenerated columns appear to the RIGHT. If you want them to be on the left, you have to add code to the RowCreated event which deletes and re-adds all columns, like so:

  protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
  {
        GridViewRow row = e.Row;
        List<TableCell> columns = new List<TableCell>();

        foreach (DataControlField column in GridView1.Columns)
        {
            TableCell cell = row.Cells[0];
            row.Cells.Remove(cell);
            columns.Add(cell);
        }

        row.Cells.AddRange(columns.ToArray());
    }
