Hello.
I use automatic column validation in RadGridView (ValidatesOnDataErrors="InViewMode" in every column). If some row's cell has error, RadGridView show whole row as incorrect. How can I change this behavior and display errors only in the cells themselves, and not in whole rows?

Hello Aleksey,

In order to resolve your problem, may I ask you which method for validation you are using? If you do not have any validation logic (using framework validation) you will get the validation error for a cell.

I can suggest you to check this help article, where you can find information about GridView's validation.

Looking forward to hearing from you!

Thank you for your reply.
I use MVVM pattern and IDataErrorInfo. Here is an example of declaring a column in the View:

<telerik:GridViewDataColumn MinWidth="80" Width="100" Header="Январь" DataMemberBinding="{Binding Month01.V.Fact, Converter={StaticResource DecimalToStringConverter}}" TextAlignment="Right" ValidatesOnDataErrors="InViewMode">
                        <telerik:GridViewDataColumn.CellTemplate>
                            <DataTemplate>
                                <ctrl:ArticleValueCellControl IsChecked="{Binding Month01.V.Formula}" IsCheckable="{Binding Month01.V.HasFormula}" Value="{Binding Month01.V.Fact, Converter={StaticResource DecimalToStringConverter}, NotifyOnValidationError=True, ValidatesOnDataErrors=True}" />
                            </DataTemplate>
                        </telerik:GridViewDataColumn.CellTemplate>
                        <telerik:GridViewDataColumn.CellEditTemplate>
                            <DataTemplate>
                                <ctrl:ArticleValueCellEditControl IsChecked="{Binding Month01.V.Formula, Mode=TwoWay}" IsCheckable="{Binding Month01.V.HasFormula}" Value="{Binding Month01.V.Fact, Mode=TwoWay, Converter={StaticResource DecimalToStringConverter}}" />
                            </DataTemplate>
                        </telerik:GridViewDataColumn.CellEditTemplate>
                    </telerik:GridViewDataColumn>
