I'm trying to set the DataNavigateUrlFormatString property of the Hyperlink column in a DataGrid at run-time, but don't seem to be able to access it like this: grdDatagrid.Columns(0).DataNavigateUrlFormatString = "../hardware/hw-edit.aspx?asset_id={0}". The error I'm getting is: "The name 'DataNavigateUrlFormatString' is not a member of 'System.Web.UI.WebControls.DataGridColumn'." However, it is possible to access the HeaderText property of the Hyperlink Column in the same manner. I understand that the HeaderText property is inherited from the DataGridColumn class, but the DataNavigateUrlFormatString is not.<BR><BR>Thanks,<BR><BR>Sacha
