This example demonstrates how to add the ASPxValidationSummary control to ASPxGridView's EditForm:
- Specify a custom EditFormTemplate;
- Replace auto-generated EditForm editors via the ASPxGridViewTemplateReplacement (ReplacementType=EditFormEditors);
- Add the ASPxValidationSummary control to collect EditForm Template validation errors;
- Perform the client-side EditForm Template validation via the client-side ASPxClientEdit.ValidateEditorsInContainer method.
