Row validation not changing when valid

[Arthur]

Hi,

I have a grid where I have set the column to valid on property changed which works fine, The red validation appears when invalid and goes when notvalid.

However, a thin red line box persists around the now valid item. I would like to

1) Either remove this secondary validation altogether
2) Would like to align the validation process of this secondary validation so that it also works on property changed



Thanks

Hello,

May I ask you to share some more detailed information on how have you implemented the validatation? What is the invalid value you have entered - is it a value with not the right type or other (not satisfying condition defined by you)?

Hi Didie,

The validation uses IDataErrorInfo and it s checking if the data in a cell is duplicated in another cell.

The columns definition is 

 <telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name}"  Width="Auto" IsReadOnly="{Binding IsReadOnly}>
                            <telerik:GridViewDataColumn.CellEditTemplate>
                                <DataTemplate>
                                    <TextBox Text="{Binding Name, UpdateSourceTrigger=PropertyChanged, NotifyOnValidationError=True, ValidatesOnDataErrors=True}" MaxLength="50" />
                                </DataTemplate>
                            </telerik:GridViewDataColumn.CellEditTemplate>
                        </telerik:GridViewDataColumn>       


When the cell is invalid it immediately has a thick red border without the need to tab. However, if I then change it to a valid value the thick red border disappears and a thin red border remains.
