I have two tables - one called Contract, one called Sow. Contract has a foreign key that points to SOW. What I'd like to do is to be able to edit the Contract details and provide a drop down list of different SOW records to choose from. The current code:
In my Contract Controller:
public ActionResult Edit(int id)
{
Contract contract = contractRepository.GetContract(id); [code]...
The list populates with values, but when I change them and update, the foreign key does not change.

I have a listbox in the formview. The listbox has selectionmode = multiple. The previous programmer has setup such a way when a user selects multiple items in the listbox, the data are stored with comma delimiter. For example, Listbox have values A, B, C, D, E. If user selected A, C, E and the data are stored in a field as A,B,C. Now the business requirement has changed and the user should be able to edit the data they entered. I want to able to show user which data they selected when they inserted data i.e. In the edit mode, the listbox should have A,C,E as highlighted. How can I do that? I can not use Eval("fieldname") because the listbox can not find the data "A,C,E" in the available listitems.

I have a transaction table with a field called product. There is a limited number of choices for product so I also have a product table. I am showing the transactions in a ListView with a dropdownlist for Product. The field Product can be blank (all works well then). The user can leave the field blank or they can choose from the dropdownlist. I am running into a problem with the dropdownlist in the Edit Template. No matter what the product is in the transaction file, I get a page error of "ddlEditProduct has a SelectedValue which is invalid because it does not exist in the list of items". I have verified the product does exist in the product table.
<asp:DropDownList ID="ddlEditProduct" runat="server"
DataSourceID="dsProduct"
DataTextField="Product"
DataValueField="Product"
AppendDataBoundItems="true"
SelectedValue='<%# Bind("Product") %>' >
<asp:ListItem Selected="True"></asp:ListItem>
</asp:DropDownList>

In my edit template I want a dropdownlist containing a list of possible customers. The list is populated from a database table containing existing customers. If the main record has customer "XYZ", then I want that customer to be the default in the dropdown. I'm using VS 2008 and C# My markup for the dropdownlist is currently:
[Code]....
The dropdownlist is populated but the problem is it shows the first customer in the list. I don't want the user to have to rechoose customer if that is not what they are changing.

I have create a grid view with a dropdownlist for one of the columns. This works fine, but when I click edit and then update I get an error saying it cant update due to null value. I'm sure it because the parameter in the update of SqlDataSource1 is not referring to the value select in the edit item template, but I cant figure out how to do this.
My code is below.
<asp:SqlDataSource
ID="SqlDataSource1"
runat="server"

ConnectionStrings:BlazeBillzConnectionString %>"

[Prod_Sold_ID], [Order_Date], [Billing_Period] FROM [ProductsSoldTable] where Prod_Sold_ID < 130"

I have created a Gridview (using ObjectDataSource) for Edit/Updates. I am getting an error on my DropDownList which is configured with the list items Yes and No only for both text and values.
Most of my data in my SQL table has values of either Yes or No, however there are some records that are BLANK or even NULL sometime.These rows fail in my GridView when attempting to Edit.
I tried going into the DDL Edit List items and adding a Blank with and empty value however each time i try to save the page VWD removes it.
How do i account for reverse lookups of all possible values Yes/No/Blank or Empty/NULL in my DDL?

I have created two dropdown lists. The 2nd DDL depends for values on the 1st DDL. I have written code on the SelectedIndexChanged event of 1st DDL to change values of 2nd DDL. also i have used detailsview. In the template field i have used 2 DDL mentioned above. they are having SelectedValue='<%# Bind("") %>' property. Everything works fine but when i tried to edit record in detailsview & select value from 1st DDL then it gives me following error.
Server Error in '/' Application. Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. 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.

I read your article on ASPSnippets and everything worked great. I am having one problem and this is preventing me from moving forward. When I select the edit for a row (I only have two columns), the drop down comes back blank (no records). I have looked at the code multiple times and can't see where I made a mistake. is it possible to control the width of the drop down list? I can't tell if the column automatically adjusts because I am not returning any records.

using System.Collections.Generic;
