RadGridView and the DataFormValidationSummary

[Steve]

Hi,
Is there any way to integrate the DataFormValidationSummary control with the RadGridView?
Thanks in advance,
Steve

Hello Steve,

Will it be possible to carify what the exact behavior you want to get is ? Do you want just to display the errors in a separate control below the grid for example ?

Yes, in as a separate control under the grid, as it is with the data form.  The main thing is how to map the grid validation to it.
Thanks,

Hello Steve,

You will need to expose a collection property to keep track of the errors in the grid and bind it to the validation summary. However, you can just create an ItemsControl for example and bind it to those errors without the need to work with DataFormValidationSummary.

I assume that for validating user input, the best course of action is to handle the CellValidated event and add the ValidationResult to a collection, but if existing data (from a data source) is invalid (exceeds valid string length), how can I get at that ValidationResult?
Thanks in advance,
Steve

Hello Steve,

Will it be possible to clarify how you get this error ? Do you work with DataAnnotation and set Length restriction or you perform check in the property setter for example ?

I use DataAnnotations.

Hello Steve,

In this case my recommendation is to take a look at one of those articles (link 1, link 2, link 3).
