[Solved] CellTemplate for ChildTable

[Martin]

Hi,

I would like to have a cell template for the ChildTable to display the color like in the "main" table.

How can I archive this?

Thanks,

Martin

Here is my code:

<telerik:RadGridView.ChildTableDefinitions>
               <telerik:GridViewTableDefinition>
                    <telerik:GridViewTableDefinition.Relation>
                        <telerik:PropertyRelation ParentPropertyName="Relation"/>
                    </telerik:GridViewTableDefinition.Relation>
                </telerik:GridViewTableDefinition>
            </telerik:RadGridView.ChildTableDefinitions>
         <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="Color" DataMemberBinding="{Binding Color}">
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <Border Width="30" Height="20" Background="{Binding Color}"/>
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellTemplate>
                </telerik:GridViewDataColumn>
                       <telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name}">
                </telerik:GridViewDataColumn>
                 </telerik:RadGridView.Columns>
        </telerik:RadGridView>

Hello Martin,

You can define a CellTemplate for child tables using Custom Hierachy Template.
If you need any further assistance, please let me know.

Thank you - that helped me alot.

But I have another question. When I select a Item in the ChildTable - how can I get the SelectedItem?
If I use radGridview.SelectedItem I get "null".

Thanks,

Martin

Hello Martin,

As you defined a HierachyChildTemplate,  you can use the RowLoaded event to access rows in child grids-please use the following forum thread for a reference.

Hello Vanya,

thanks for your answer. That does not help me getting the SelectedItem from the ChildRow. I need the Selected Item of the Child Row when it's selected by the costumer.

Thanks,

Martin

Hi Martin,

You can use the SelectionChanged event of the child gridview to get the selected item. You can store it in a variable and use it later when you need it.

I tried it. But sometimes I get no result. Do you have any examples?

[Vanya Pavlova]

Hello Martin,

You may use the following code:

private void childGrid_SelectionChanged(object sender, Telerik.Windows.Controls.SelectionChangeEventArgs e)
{
     var item = this.childGrid.SelectedItem as MyObject;
     MessageBox.Show(item.ID.ToString());
}

That does not work either - for some childGrids I don't get the selected item, its "null".

Is this a bug ?

Hi Martin,

Everything works fine on my side, please submit a support ticket and send us a small application that reproduces this behavior, because obviously there is something specific in your scenario.
