Show / Hide Context menu items in dxgrid per row

Hi,

I'm using dxg:GridControl for my WPF application, which is binding the bank details which status will be active or deleted, for active banks, I would like to have Edit and Delete action when I right click the row, but for deleted banks, I only would like to have Edit action, may I know if there is any approach to only show Edit for those deleted banks. Thanks a lot!

C#
<dxg:GridControl ItemsSource="{Binding BankSource">  
                        <dxg:GridControl.View>  
                            <dxg:TableView AutoWidth="True" AllowPerPixelScrolling="True" ShowGroupPanel="False" AllowFilterEditor="False" ShowGroupedColumns="True"  
                                    BestFitMode="Smart" BestFitArea="All" ShowHorizontalLines="False" AllowEditing="False" NavigationStyle="Row" AllowHorizontalScrollingVirtualization="False" FadeSelectionOnLostFocus="False"  
                                    ShowIndicator="False" FocusedRow="{Binding Path=SelectedBank, Mode=TwoWay}">  
                            </dxg:TableView>  
                        </dxg:GridControl.View>  
                        <dxg:GridControl.ContextMenu>  
                            <ContextMenu>  
                                <MenuItem Name="mnuEdit" Header="Edit ..." Command="{Binding UpdateBankCommand}" CommandParameter="{Binding SelectedBank}"/>  
                                <Separator/>  
                                <MenuItem Name="mnuDelete" Header="Delete" Command="{Binding DeleteBankCommand}" CommandParameter="{Binding SelectedBank}"/>  
                            </ContextMenu>  
                        </dxg:GridControl.ContextMenu>  
                        <dxg:GridControl.Columns>  
                            <dxg:GridColumn FieldName="name" Header="Bank Name" Width="80" />  
                            <dxg:GridColumn FieldName="acctNum" Header="Card Number" Width="250" />  
                            <dxg:GridColumn FieldName="acctName" Header="Holder Name" Width="90" />  
                            <dxg:GridColumn FieldName="StatusDesc" Header="Status" Width="70" />  
                        </dxg:GridControl.Columns>  
                    </dxg:GridControl>

Hello,

We suggest using the TableView.RowCellMenuCustomization property to create a context menu for GridControl rows. You can read more here: Context Menus.

With this approach you can bind the BarButtonItem.IsVisible property to a property of an object in the row. I have created a simple example to show this approach. Try it and let me know your results.

Thanks,
Andrey

I have unbound column with type bool.

I wanted to show context menu only if that unbound field value is true.

I have set xaml as follows:

XAML
<dxg:GridControl.View>  
                <dxg:TableView ShowGroupPanel="False"  AllowEditing="False">  
                    <dxg:TableView.RowCellMenuCustomizations>  
                        <dxb:BarButtonItem Content="Delete this Time from SR"  
                                           Command="{Binding View.DataContext.DeleteTimeCommand}"  
                                           CommandParameter="{Binding Row.Row}" >  
                            <dxb:BarButtonItem.Style>  
                                <Style TargetType="dxb:BarButtonItem">  
                                    <Style.Triggers>  
                                        <DataTrigger Binding="{Binding Row.Row.GeneratedSR}" Value="True">  
                                            <Setter Property="IsVisible" Value="False"/>  
                                        </DataTrigger>  
                                    </Style.Triggers>  
                                </Style>  
                            </dxb:BarButtonItem.Style>  
                        </dxb:BarButtonItem>  
                    </dxg:TableView.RowCellMenuCustomizations>  
                </dxg:TableView>  
            </dxg:GridControl.View>  


 <dxg:GridColumn FieldName="GeneratedSR" x:Name="GeneratedSR" UnboundType="boolean" HorizontalHeaderContentAlignment="Center"  Width="1*"/>

But it is not working, could you please review it

Hi Bosko,

This doesn't work because your are binding to the GeneratedSR property that is not present in your data items. To get access to a property provided by an unbound column, use the RowData.DataContext property which contains an ICustomTypeDescriptor object:

XAML
<DataTrigger Binding="{Binding Row.DataContext.GeneratedSR}" Value="True">

Regards,
Alex

Using the RowCellMenuCustomization and the DataTrigger with Row.DataContext.Property worked for me. Would be nice if a "Visibility" property was available instead of having to jump through this hoop :)

Hello,

I created a separate ticket on your behalf: T1040947: It would be nice if a "Visibility" property was available for the RowCellMenuCustomizations items. We placed it in our processing queue and will process it shortly.
