Formview itemupdating newvalues empty
If you use Eval as shown above then you will have to set the value when it changes in the Form View Ittem Update event (see Listing 1). NET showing all of the elements generated by the designer (or added by you) is provided in Listing 2.If you switch Eval to Bind for the Selected Value then no code-behind is required. It took me a couple of hours to work out the details in a manner I was happy with.For me, I have found that enterprise applications and applications of even modest complexity require a lot of business rules and control, and managing everything from scratch supports that from the get go.I do use Bind, Eval, and User Controls heavily though.Here are the steps: The last steps require that you bind the Data Text Field and Data Value Field properties to the Customer IDData Source and the Selected Value to the original source's Customer ID.The Drop Down List should be configured to look like the ASP. The Data Source ID for the Drop Down List points at Customer IDData Source.
A friend of mine actually asked me about this particular problem: what is a good way to bind a Drop Down List in a Form View.
Since this particular challenge wasn't on my radar I provided him with a workable solution, but thought a better solution was possible.
This article provides a comprehensive solution for defining an edit template in a Form View. The Form View is a binding control like the Grid View, except where the Grid View shows multiple rows of data and the Form View shows one record at a time in a form layout.
To demonstrate data binding for a Drop Down List in a Form View switch the Form View to the Edit Item Template.
You can use the Smart tags menu or switch to the ASP.
