Hi,
I am using the PropertyRelation on the RadgridView like so:

<
Telerik:RadGridView.ChildTableDefinitions

 

    <Telerik:GridViewTableDefinition x:Name="gvtd"> 

 

        <Telerik:GridViewTableDefinition.Relation

 

            <telerikData:PropertyRelation ParentPropertyName="MyProperty"/> 

 

        </Telerik:GridViewTableDefinition.Relation
    </Telerik:GridViewTableDefinition>
</Telerik:RadGridView.ChildTableDefinitions>

Which works fine when it autogenerates the columns.. is there an example on how to user define the columns?


My futile tries involve:
AutoGenerateColoumns="False"
or   

AutoGenerateFieldDescriptors

 

="False"

I have tried setting the FieldDescriptors manually.

Tried to use HierarchyChildTemplate like so:

 

 

 

<Telerik:RadGridView.HierarchyChildTemplate

 

    <DataTemplate>

        <Telerik:RadGridView

 

            <Telerik:RadGridView.Columns
                <Telerik:GridViewDataColumn Header="ID" UniqueName="id"/>

                <Telerik:GridViewDataColumn Header="FirstName" DataMemberBinding="{Binding Name}"/>

            </Telerik:RadGridView.Columns>

        </Telerik:RadGridView>

    </DataTemplate>

</Telerik:RadGridView.HierarchyChildTemplate>


With the result of it loosing its binding and going back to the usercontrols dataContext.

Hi Martin,

You can successfully replace  GridViewTableDefinition with PropertyRelation with following HierarchyChildTemplate declaration:
...
<Telerik:RadGridView.ChildTableDefinitions>
    <Telerik:GridViewTableDefinition />
</Telerik:RadGridView.ChildTableDefinitions>
<Telerik:RadGridView.HierarchyChildTemplate>
     <DataTemplate>
        <Telerik:RadGridView ItemSource="{Binding MyProperty}" AutoGenerateColumns="False"
            <Telerik:RadGridView.Columns>
                <Telerik:GridViewDataColumn Header="ID" UniqueName="id"/>
                <Telerik:GridViewDataColumn Header="FirstName" DataMemberBinding="{Binding Name}"/>
            </Telerik:RadGridView.Columns>
        </Telerik:RadGridView>
    </DataTemplate>
</Telerik:RadGridView.HierarchyChildTemplate>
...

Hi Vlad,

What if you still want to enforce the PropertyRelation between the Parent and the Child Items. You example chooses the correct child columns by the relation is lost.

How do you maintain the related master detail relationship.

Thanks

Toby.

Hello,

 Can you post more info about your scenario? How the grid is declared and bound in your case?

Hi Support,

Is it possible to "inherit" the column definition from the parent table?

I have implemented a column picker so the user can pick what columns are visible, i want this to affect the child tables.

Regards,
James

Hi,

 Maybe you should bind columns visibility to all grid definitions if you want your setting to affect all grids including child grids in hierarchy. You can declare your child grids using HierarchyChildTemplate.
