Rowvalidating aspxgridview

New Values should populate with the new value that was updated, for the Field Name passed to it. For that, you need to check your datasource and make sure the field name is what you expect it to be. I changed the Field Name to a different name, "Shale Play", just to test. And it actually said, "A field or property with name ' Shale Play' was not found in the selected data." For issue one, the data source is being bound at design time. I'm changing the value of the Shale Play field and the Row Validating event is firing as expected. Note that that might be different than, for instance, the name of the column in your database (depending on how your Grid View is populated).

To manually force row validation, call the ASPx Grid View. Data columns provide various validation settings available via the Edit Properties. This allows you to define the validation logic for individual edit cells. Required Field property to force an editor to require input, and specify an error message if input is not received.
