[Solved] LeftClick Context Menu not Firing

[Ben]

I'm having an issue with upgrading my existing application to use the latest release of the GridView.  The following sample shows my issue.  Essentially, I'm trying to show a ContextMenu using the Ctrl+Left Click Modifier.  I cannot get the context menu to show on the rows or headers, it seems like there is another control handling the event.

<UserControl x:Class="Telerik_Q2_2010_Samples.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:c="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"
    xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"
    xmlns:grid="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
    mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">

    <Grid x:Name="LayoutRoot" Margin="30">

        <grid:RadGridView ItemsSource="{Binding}" AutoGenerateColumns="False">
            <c:RadContextMenu.ContextMenu>
                <c:RadContextMenu ModifierKey="Control" EventName="MouseLeftButtonDown">
                    <c:RadMenuItem Header="Test" />
                </c:RadContextMenu>
            </c:RadContextMenu.ContextMenu>
            <grid:RadGridView.Columns>
                <grid:GridViewDataColumn Header="FirstName" Width="*" IsReadOnly="True" DataMemberBinding="{Binding FirstName}" />
                <grid:GridViewDataColumn Header="LastName" Width="*" IsReadOnly="True" DataMemberBinding="{Binding LastName}" />
            </grid:RadGridView.Columns>
        </grid:RadGridView>
    </Grid>
</UserControl>

And here is my code-behind.

using System.Collections.Generic;
using System.Windows.Controls;

namespace Telerik_Q2_2010_Samples
{
    public partial class MainPage : UserControl
    {
        public List<Customer> Customers { get; set; }

        public MainPage()
        {
            InitializeComponent();

            Customers = new List<Customer>()
                            {
                                new Customer { FirstName = "John", LastName="Doe" }
                            };
            DataContext = Customers;
        }
    }

    public class Customer
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
    }
}

Hi,

 Generally grid elements responsible for something on MouseLeftButtonDown will handle the event internally. Data rows for selection, headers cells for sorting, etc. Can you explain a bit more about your scenario and why you need to menu on left click?

Kind regards,

Vlad,

We are running SL3 and don't have the right mouse button support.  This is what we used in the older version.  Do you have any key modifier recommendations that don't include the right moust button?

Thanks,

[Vlad]

Hi,

 Our context menu will work on Silverlight 3 as well if you set windowless=true for your plug-in. You can check this demonstrated on our Silverlight 3 demo.

Best wishes,
