Dear all,

I try to use DropDownList in DetailsView. First , I set up
a sqlDataSource which is connected to a table named "Shipper". The
table has only two fields named Shipper_Code and
Shipper_Name. When I used Edit Template to edit EditItem Template. and
try to use Edit Databinding , but the Radio Button for Binding
Selected value and other value are all disabled.

So I try to use custom binding code expression, and I type in Bind
("Shipper_Code"). But when I try to run the program to open the
Details View Editing function , it returns the following error:

databinding 'system.data.datarowview' does not contain a property with
the name "Shipper_Code"

I have double check the Database field name and found it is correct.
The following is my code:

Hi,

The data you bind to the DropDownList is assigned to each ListItem
respectively when the DataBind event occurs. However, you are trying to use
"Bind" within the "EditItemTemplate" of the DetailsView. That means that
ASP.NET is looking for that field within the DataItem assigned to the
DetailsView by SqlDataSource2. And SqlDataSource2 does not have such a field
called "Shipper_Code".
