Default How can i change the textbox into a dropdownlist

 Hi guys:

i was trying to change the text box in the Edit template in the form control to a dropdown list. However, when i tried to press the Edit Button to test it, an error page came with a message saying:

Server Error in '/ECBS' Application.

'DepaNameTextBox' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

what i did is the following change from text box to dropdown list:


<asp:dropdownlist ID="DepaNameTextBox" runat="server" text='<%# Bind("DepaName") %>' Width="137px"></asp:dropdownlist><br />

as you can see the dropdownlist is binded to 'depaName' column. so my next question is, how can i let the dropdown list display the name of the record that was first inserted when i press the edit button to edit that record.

many thanks to any helper

You cannot convert a textbox into a dropdownlist. You need to add a dropdownlist to the template. Then on the RowDataBound event get a reference to the textbox and a reference to the dropdownlist. Then you can do a findbytext to set the ddl.
