I have a GridView with a HierarchyChildTemplate that has a Grid View. I need a context menu in that ChildTemplate GridView that sees things on the View Model. How do I get it to see the viewmodel for the proper binding?

Code:

<telerik:RadGridView Grid.Row="0"

x:Name="radGridView"

ItemsSource="{Binding Items}"

AutoGenerateColumns="False"

SelectionMode="Extended"

SelectionUnit="FullRow"

ShowGroupPanel="False"

Margin="25,25,25,25"

ui:MultiSelectorBehaviours.SynchronizedSelectedItems="{Binding Path=SelectedItems}"

AllowDrop="True"

IsFilteringAllowed="True">

<telerik:RadGridView.ChildTableDefinitions>

<telerik:GridViewTableDefinition/>

</telerik:RadGridView.ChildTableDefinitions>

<telerik:RadGridView.HierarchyChildTemplate>

<DataTemplate>

<telerik:RadGridView ItemsSource="{Binding ProjectionTasksLink}"

AutoGenerateColumns="False"

SelectionMode="Extended"

SelectionUnit="FullRow"

ShowGroupPanel="False"

AllowDrop="True">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Projection"

UniqueName="Name"

DataMemberBinding="{Binding}"

CellTemplate="{StaticResource CellTemplate.TaskName}"

IsReadOnly="True"/>

<telerik:GridViewDataColumn Header="Run Parameter Set"

UniqueName="RunParametersLink"

DataMemberBinding="{Binding}"

CellTemplate="{StaticResource CellTemplate.RunParameterSetName}"

IsReadOnly="True"/>

</telerik:RadGridView.Columns>

<telerik:RadGridView.ContextMenu>

<ContextMenu>

<MenuItem Header="Run Selected Item(s)"

DataContext="{Binding Path=PlacementTarget.DataContext, RelativeSource={RelativeSource AncestorType=ContextMenu}}"

Command="{Binding RunAllSelectedTasksCommand}"

CommandParameter=

"{Binding Path=PlacementTarget.SelectedContexts, RelativeSource={RelativeSource AncestorType=ContextMenu}, Converter={StaticResource runControllerJobCmdConverter}}"

>

<MenuItem.Icon>

<Image Source="Images/Run16.png" />

</MenuItem.Icon>

</MenuItem>

</ContextMenu>

</telerik:RadGridView.ContextMenu>

</telerik:RadGridView>

</DataTemplate>

</telerik:RadGridView.HierarchyChildTemplate>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Run Page Name"

UniqueName="Name"

CellTemplate="{StaticResource CellTemplate.RunPageName}"

DataMemberBinding="{Binding}"

IsReadOnly="True"/>

<telerik:GridViewDataColumn Header="Target Model Object"

UniqueName="AssociatedTargetModelObjectLink"

DataMemberBinding="{Binding}"

CellTemplate="{StaticResource CellTemplate.TargetModelObjectName}"

IsReadOnly="True"/>

<telerik:GridViewDataColumn Header="InputManager"

UniqueName="AssociatedInputManagerLink"

CellTemplate="{StaticResource CellTemplate.InputManagersList}"

DataMemberBinding="{Binding}"

IsReadOnly="True"/>

</telerik:RadGridView.Columns>

<telerik:RadGridView.ContextMenu>

<ContextMenu>

<MenuItem Header="Run Selected Item(s)"

DataContext="{Binding Path=PlacementTarget.DataContext, RelativeSource={RelativeSource AncestorType=ContextMenu}}"

Command="{Binding RunAllSelectedTasksCommand}"

CommandParameter=

"{Binding Path=PlacementTarget.SelectedContexts, RelativeSource={RelativeSource AncestorType=ContextMenu}, Converter={StaticResource runControllerJobCmdConverter}}"

>

<MenuItem.Icon>

<Image Source="Images/Run16.png" />

</MenuItem.Icon>

</MenuItem>

</ContextMenu>

</telerik:RadGridView.ContextMenu>

</telerik:RadGridView>

The context menu in the parent grid is fine, but the one in the nested grid is not right.

Side question. Is there a better way to do the nested grid thing than the HierachyTemplate? I would like for this to be one grid that does nesting. I tried using ChildTableDefinitions, but I can't specify things like columns and what not.

Thanks,
Greg

Hello,

I have attached a sample project to show you what I mean. In the test project I have bound the Header for the MenuItem to the SelectedItem object in the ViewModel, so when the ContextMenu is shown the Name of the selected item will be displayed.

I hope you can apply this into your solution.
