I have a gridview control with a template column that has a dropdown list.
I am trying to set the selected value with the code below but it does not
seem to work. It runs ok, no error but the value "minor" is not showing up
as selected, any ideas, thanks.

(e.Row.Cells[3].FindControl("drdnSeveritygv") as DropDownList).SelectedValue
= "minor";
 
Hi,

at which point in code (Page_Load, Prerender, Button's click,RowDataBound
etc) are you trying to do this? Is it sure that databinding doesn't clear it
e.g that you set it first and call DataBind() immediately after?
 
Hi it is in the rowdatabound event. The actual code is

(e.Row.Cells[2].FindControl("ddrlist") as DropDownList).SelectedValue =
Convert.ToString(discSubCatnew.ID);
discSubCatnew.ID = an integer and this integer corresponds to the data value
field in the dropdown. Would you have to set it after you call databind?
