I had used dropdown list in datagrid. At first when the grid is shown then the data is shown in a label but after click on the edit button of the datagrid, the data is shown in dropdownlist using edit item template.here i dont know how to display the selected value same as that of the label's value.Please suggest me how can i display the selected value.
I am working in Visual studio 2005(ASP.Net c#) and backend as ms-access.

my problem solved by inserting the following in datagrid properties in html i.e. in source phase of designer

SelectedValue=' <%# DataBinder.Eval (Container.Data Item,"fieldname ")%>'>
