Formview itemupdating e newvalues

As you would if working with a Data Source control, click on the Label's Smart Tag and select Edit Data Bindings.

When the Data Bindings dialog appears, the dropdown lists that normally display the items you can bind to will be empty.

Form View and SQL Datasource is awesome in my opinion. Return sql Return Catch ex As Exception Throw ex End Try End Function The problem is that how does databinding work?

You can just bind your controls to data field in the markup, its great. It won't work the same way as having the sql data source in the markup. Well here is a trick to do it: For example, to Update, handle the Form View's Item Updating event, and then loop through each value in the Update Parameters list in the sqldatasource, and manually assign each value from e. Private Sub frm Data_Item Updating(By Val sender As Object, By Val e As System.

I first check to see if the List is in the Session object and, if it isn't, build it.

I then set the Form View's Data Source to the List: Next, you must add these two lines of code to the page's Pre Render event so they execute after any activity you perform with the Form View elsewhere in the Page.


Anyway, if you want to create your SQLData Source in the code behind, you can easily do that. Update Command Type = Sql Data Source Command Type. However, the Form View (and the rest of the Data Views) will work just as well with any collection of objects: Lists, Arrays, Array Lists, or whatever collection you want to make available to the user for display and update.You won't get automatic generation of the Data View's templates and you'll have to write a little code, but from the user's point of view, everything works as if your Data View was tied to a Data Source.
