How to get UnboundColumn to show validation error when the input is invalid
posted 



 


                        <igGrid:UnboundColumn Key="UNBOUND" ValueConverter="{StaticResource ConvertValue}">
                            <igGrid:UnboundColumn.EditorTemplate>
                                <DataTemplate>
                                    <TextBox Text="{Binding RowData.Value, Mode=TwoWay}"/>
                                </DataTemplate>
                            </igGrid:UnboundColumn.EditorTemplate>
                        </igGrid:UnboundColumn>


 

Above is my column definition. The Value's type is Decimal. If I enter some garbage in the text box, such as "ASdf" I expect to see some validation error. The error is shown for a TextColumn.

I am using a ValueConvertor because the displayed value is dependent on the value in a different column.

    Hi,

    You should enable validation on your editor binding:

     

    <DataTemplate>
    <TextBox Text="{Binding RowData.Value, Mode=TwoWay, NotifyOnValidationError=True, ValidatesOnExceptions=True}"/>
</DataTemplate>

     

     Hope this helps,
