Combobox is locked during validation

[Maciej]

Hi Telerik's Support

I've got ComboBox in GridView's EditTemplate and I've got not null validation on selected item on client side. But when I delete value from ComboBox and it is empty it is also locked, so I can't select other record from GridView or click on button from other part of window, until I select some value from locked ComboBox.

This is my xaml code:

<!-- Style for EditCell not based on other styles-->
<Style TargetType="telerik:GridViewEditorPresenter"/>

<!-- My ComboBox -->
<telerik:GridViewDataColumn.CellEditTemplate>
    <DataTemplate DataType="models:BookkeepingSchemaModificationObject">
           <telerik:RadComboBox ItemsSource="{Binding Path=BookkeepingAccounts}"
                                 SelectedValuePath="Guid"
                                 SelectedValue="{Binding Path=CreditBookkeepingAccountId, Mode=TwoWay}"
                                 telerik:TextSearch.TextPath="AccountFullName"
                                 IsEnabled="{Binding Path=IsSelected}">

                     <telerik:RadComboBox.ItemTemplate>
                           <DataTemplate>
                                 <Grid>
                                     <Grid.ColumnDefinitions>
                                          <ColumnDefinition Width="Auto"/>
                                               <ColumnDefinition Width="15"/>
                                               <ColumnDefinition Width="*"/>
                                         </Grid.ColumnDefinitions>
                              <TextBlock Grid.Column="0" Text="{Binding Path=AccountNumber}" Margin="4,4,0,4" VerticalAlignment="Center"/>
                               <TextBlock Grid.Column="1" Text="-" HorizontalAlignment="Center" Margin="0,4" VerticalAlignment="Center"/>
                               <TextBlock Grid.Column="2" Text="{Binding Path=AccountName}" TextWrapping="Wrap" Margin="0,4" VerticalAlignment="Center"/>
                                     </Grid>
                                </DataTemplate>
                       </telerik:RadComboBox.ItemTemplate>
                </telerik:RadComboBox>
         </DataTemplate>
</telerik:GridViewDataColumn.CellEditTemplate>

What can I do, to make ComboBox not locking other controls though the validation.

I've found the solution. Only thing is setting ValidatesOnDataErrors="InViewMode" in GridView properties. Hope it will be helpfull to someone else ;)
