GridView Group Dragging in the menu

[Nick Wood]

Hi There

I have a menu which contains a gridview, I cant seem to drag column headers to the group header though when in that menu. The menu just dissappears. Code for the grid below:

<telerikGridView:RadGridView x:Name="radGridAssets" Grid.Column="0" Grid.Row="0"
                                             Margin="0" ShowGroupPanel="True" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
                                             ShowInsertRow="False" RowIndicatorVisibility="Collapsed"
                                             AutoGenerateColumns="False"
                                             ItemsSource="{Binding FullAssetList}">

            <!--<telerikGridView:RadGridView.GroupDescriptors>
                <telerikData:GroupDescriptor Member="SiteName" />
            </telerikGridView:RadGridView.GroupDescriptors>-->
            <telerikGridView:RadGridView.SortDescriptors>
                <telerikData:SortDescriptor Member="SiteId" SortDirection="Ascending" />
                <telerikData:SortDescriptor Member="OrderByProcessType" SortDirection="Ascending" />
            </telerikGridView:RadGridView.SortDescriptors>
            <telerikGridView:RadGridView.Columns>
                <telerikGridView:GridViewDataColumn Header="" Width="Auto">
                    <telerikGridView:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <CheckBox x:Name="chkSelectedAsset" IsChecked="{Binding IsSelected, Mode=TwoWay}"
                                      Unchecked="chkSelectedAsset_Unchecked" Checked="chkSelectedAsset_Checked" />
                        </DataTemplate>
                    </telerikGridView:GridViewDataColumn.CellTemplate>
                </telerikGridView:GridViewDataColumn>
                <telerikGridView:GridViewDataColumn Header="Site" DataMemberBinding="{Binding SiteName}" IsReadOnly="True">
                    <telerikGridView:GridViewDataColumn.GroupHeaderTemplate>
                        <DataTemplate>
                            <StackPanel Orientation="Horizontal" >
                                <TextBlock Text="{Binding Group.Key}" />
                                <Button x:Name="buttAssetGridSelectAll" Margin="5,0,0,0" Content="All" FontSize="10" Tag="{Binding Group}" Click="buttAssetGridSelectAll_Click"  />
                                <Button x:Name="buttAssetGridSelectNone" Content="None" FontSize="10" Tag="{Binding Group}" Click="buttAssetGridSelectNone_Click" />
                            </StackPanel>
                        </DataTemplate>
                    </telerikGridView:GridViewDataColumn.GroupHeaderTemplate>
                </telerikGridView:GridViewDataColumn>
                <telerikGridView:GridViewDataColumn Header="Asset Name" DataMemberBinding="{Binding AssetName}" />
                <telerikGridView:GridViewDataColumn Header="Process" DataMemberBinding="{Binding ProcessType}" />
                <telerikGridView:GridViewDataColumn Header="SiteId" DataMemberBinding="{Binding SiteId}" IsReadOnly="True" IsVisible="False" />
                <telerikGridView:GridViewDataColumn Header="OrderBy" DataMemberBinding="{Binding OrderByProcessType}" IsReadOnly="True" IsVisible="False" />
            </telerikGridView:RadGridView.Columns>
        </telerikGridView:RadGridView>

Hi Nick,

 
Thank you for sending this snippet. I have just tested it with our latest binaries and everything works fine by my side. Can you please check the attached project and let me know how it differs from yours. In addition to this you can open a new support ticket where you can attach a sample project which could help us to investigate the issue and to provide you with an appropriate solution.

Hi Vanya

Thanks for the demo, but the issue is that the grid is within a RadMenu it the content of a menu item

telerik:RadMenuItem


So as soon as I try to drag, the menu disappears.

I have actually modified your code from your example with the menu wrapped around the grid. I tried to attach, but cant from the forum here so the code is below:

<Window

    x:Class="WpfApplication56.MainWindow"
    x:Name="Window"
    Title="MainWindow"
    Width="640" Height="468">


    <Grid x:Name="LayoutRoot" DataContext="{Binding Source={StaticResource SampleDataSource}}">
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>

        <telerikGridView:RadMenu Grid.Column="0" Grid.Row="0">
            <telerikGridView:RadMenuItem Header="Tester">

Hi Nick Wood,

Currently, there is no build in mechanism that will allow the functionality in this scenario. We have spend some time searching for suitable workaround. However, currently there is no available solution.

Please, excuse us for the inconvenience.
