Hi,

I'm trying to add/edit some data in a GridView and need to access the SelectedValue of a drop downlist that is in the grid.

My code is this:

GridViewRow gvRow = this.grdPhones.Rows[e.RowIndex];
Guid PhoneType = new Guid(((DropDownList)(gvRow.Cells[1].Controls[0])).SelectedValue.ToString());

And the error I get is this:

System.InvalidCastException was unhandled by user code
Message="Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.DropDownList'."
