Can I hide Data errors in edit mode

[Jason]

I have a gridview that has some errors using DataErrorInfo. When in edit mode, I use cell_validating to potentially set an edit error. However, I then get 2 error controls (red border) overlapping each other. Is it possible to hide or switch off the data layer errors whilst in edit mode?

Hi Jason,

Setting the ValidatesOnDataErrors property of RadGridView to "InViewMode" should disable the Error message that comes up from the IDataErrorInfo interface and only the validation error related to the CellValidating event. Can you please test setting it and update the thread whether this is the functionality you aim for?

I had the grid set up in that manner already. My actual issue was that the custom editor had the ValidateOnDataErrors property set to true (which was the default). Switching this off on construction of the editor hid the data errors as I wanted.

 

Thanks

Hello Jason,

Great to hear that you have resolved the validation duplication. I am adding a code snippet on setting the ValidatesOnDataErrors property in CellEditTemplate in case some other member experiences a similar issue:

<telerik:GridViewDataColumn.CellEditTemplate>
                        <DataTemplate>
                            <TextBox Text="{Binding SomeProperty, ValidatesOnDataErrors=False}"/>
                        </DataTemplate>
</telerik:GridViewDataColumn.CellEditTemplate>

In case your scenario is different, you can also add the approach from your end.
