HierarchyChildTemplate expanded

[Calin Calin]

Hi,

I have a grid defined like this:

<Controls:RadGridView ItemsSource="{Binding Path=DishTypes}" ShowGroupPanel="False" CanUserDeleteRows="False" CanUserInsertRows="False" CanUserFreezeColumns="False"
                                      AutoGenerateColumns="False" RowDetailsVisibilityMode="Visible" IsReadOnly="True" ShowColumnHeaders="False"
                                      RowIndicatorVisibility="Collapsed" GridLinesVisibility="Horizontal">
                    <Controls:RadGridView.ChildTableDefinitions>
                        <Controls:GridViewTableDefinition />
                    </Controls:RadGridView.ChildTableDefinitions>
                    <Controls:RadGridView.Columns>
                        <Controls:GridViewComboBoxColumn DataMemberBinding="{Binding Path=Id}"
                                                         DisplayMemberPath="Name"
                                                         SelectedValueMemberPath="Id"
                                                         ItemsSource="{Binding Source={StaticResource dishTypeData}}" />
                    </Controls:RadGridView.Columns>
                    <Controls:RadGridView.HierarchyChildTemplate>
                        <DataTemplate>
                            <Controls:RadGridView ItemsSource="{Binding Path=MenuItems}" ShowGroupPanel="False" CanUserDeleteRows="False" CanUserInsertRows="False" CanUserFreezeColumns="False"
                                                  AutoGenerateColumns="False" RowDetailsVisibilityMode="Visible" IsReadOnly="False" ShowColumnHeaders="False"
                                                  RowIndicatorVisibility="Collapsed" GridLinesVisibility="Horizontal">
                                <Controls:RadGridView.Columns>
                                    <Controls:GridViewComboBoxColumn DataMemberBinding="{Binding Path=FoodId}"
                                                                     ItemsSource="{Binding Source={StaticResource foodData}}"
                                                                     DisplayMemberPath="Name"
                                                                     SelectedValueMemberPath="Id" />
                                    <Controls:GridViewDataColumn DataMemberBinding="{Binding Path=PortionSize}" />
                                </Controls:RadGridView.Columns>
                            </Controls:RadGridView>
                        </DataTemplate>
                    </Controls:RadGridView.HierarchyChildTemplate>
                </Controls:RadGridView>

What  is the property to make all the tree children expanded (similar to clicking the + sign on all) ?

Thank you,

Calin

Hello Calin Calin,

There is no property you can set to achieve this. Instead you can use RadGridView.ExpandAllHierarchyItems() method on DataLoaded event. 
It should do the trick.

Hi Kalin Milanov,

This is the solution I have so far, I was hoping I can avoid writing code behind.

Are you planning to add such a property in the near releases ?

Thank you,

Hi Calin,

Alternatively you can use row-details instead hierarchy and set RowDetailsVisibilityMode="Visible"
