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.
