Remarks
If Model data is invalid or an error occurs during data changes, you can use the grid’s SetEditErrorText method to display a common error text in a special row at the bottom of the grid’s edit form.
This method can be used together with the automatic Model error visualization feature controlled by the grid’s MVCxGridViewEditingSettings.ShowModelErrorsForEditors property.

Note
When GridView functions in the batch edit mode, the SetEditErrorText method doesn’t work. To show edit errors in batch edit mode, use the MVCxBatchUpdateValues<T, S>.SetErrorText method. Refer to the Batch Editing topic to learn more.
