Custom header row in .NET datagrid?

How do I insert a row of identical drop-down lists into the top of my .NET datagrid?

I have a DataGrid whose source is an excel spreadsheet. My GUI needs to allow a user to select an option from a drop-down above each column. I'd like this row to be a part of the grid so that everything lines up all pretty-like.

The best option I've found is to manually create all the rows and columns and bind that to the grid. Another option was to use a repeater of datalists instead. Is there a simpler or better way? (I'm using C#)

Response by poster: I should clarify that the loaded spreadsheet is different every single time. The solution needs to dynamically apply to spreadsheets of arbitrary size and with arbitrary column names.

Best answer: You'll have to use a gridview for this, but it should work (adds a dropdown after the header row.)

protected void foo_DataBound1(object sender, EventArgs e)

GridViewRow row = new GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Normal);
for (int i=0; i<2> {
DropDownList ddl = new DropDownList();
TableCell tc = new TableCell();

(sender as GridView).Controls[0].Controls.AddAt(1, row);

 for (int i=0; i<2>  { 
should read
for (int i=0; i<2; i++) { // need to determine col. ct... Columns.Count returns 0
