How to hide ContextMenu display in code?
posted

I put ContextMenu for each row in Xamgrid like:

<XamGrid     ItemsSource="{Binding MyList, Mode=TwoWay}">
<ig:ContextMenuService.Manager>
    <ig:ContextMenuManager ModifierKeys="None" OpenMode="RightClick" >
        <ig:ContextMenuManager.ContextMenu>
            <ig:XamContextMenu Opening="XamContextMenu_Opening">
                <ig:XamContextMenu.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <CheckBox Click="CheckBox_Click"  Tag="{Binding ID}" IsChecked="{Binding IsChecked, Mode=TwoWay}" />
                <TextBlock Text="{Binding MyName}" Margin="5,0,0,0"/>
            </StackPanel>
        </DataTemplate>
                </ig:XamContextMenu.ItemTemplate>
            </ig:XamContextMenu>
        </ig:ContextMenuManager.ContextMenu>
    </ig:ContextMenuManager>
</ig:ContextMenuService.Manager>
<ig:XamGrid.Columns>
.....
</ig:XamGrid.Columns>
</XamGrid>

when user right click the row, ContextMenu popup, when click checked box inside the ContextMenu, the popup is still there. I need to click on somewhere outside of the ContextMenu popup, the popup will be gone.

So I want the ContextMenu popup gone when I click on checkbox inside the ContextMenu, how to implement it in code-behind for CheckBox_Click?

    Hi,

    If you need to close the ContextMenu in the CheckBox_Click method, you'll need to add an x:Name attribute to your grid, and then use code similar to this (assuming your grid is named 'igGrid'):

    private void CheckBox_Click(object sender, RoutedEventArgs e)
    {
        ContextMenuService.GetManager(igGrid).ContextMenu.IsOpen = false;
    }

    The other option is to use the built-in CheckBoxes functionality of the ContextMenu and its IsCheckable / IsChecked properties. Using this approach the context menu will be closed automatically when clicking the checkbox:

    <ig:ContextMenuService.Manager>
    <ig:ContextMenuManager ModifierKeys="None"
                           OpenMode="RightClick">
        <ig:ContextMenuManager.ContextMenu>
            <ig:XamContextMenu Opening="XamContextMenu_Opening">
                <ig:XamContextMenu.DefaultItemsContainer>
                    <DataTemplate>
                        <ig:XamMenuItem IsCheckable="True"
                                        IsChecked="{Binding IsChecked, Mode=TwoWay}"
                                        Header="{Binding MyName}" />
                    </DataTemplate>
                </ig:XamContextMenu.DefaultItemsContainer>
            </ig:XamContextMenu>
        </ig:ContextMenuManager.ContextMenu>
    </ig:ContextMenuManager>
</ig:ContextMenuService.Manager>

    Hope this helps,
