How To define child columns

[NS]

Hi,

I have a grid that i declare in xaml but i want to define the child columns of the hierarchy (not autogenarated).

How can you do that?

My code:

Defining the child relation
GridViewTableDefinition detailDefinition = new GridViewTableDefinition();
detailDefinition.Relation = new PropertyRelation("QueueItemActions");
radGridResubmit.TableDefinition.ChildTableDefinitions.Add(detailDefinition);


Grid declaration
       <Telerik:RadGridView HorizontalAlignment="Stretch" Width="Auto" Grid.Column="0" Grid.ColumnSpan="3" x:Name="radGridResubmit" AutoGenerateColumns="False">
                <Telerik:RadGridView.Columns>
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="" UniqueName="IsSelectedForResubmit" >
                        <Telerik:GridViewColumn.CellStyle>
                            <Style TargetType="{x:Type Telerik:GridViewCell}">
                                <Setter Property="Template" Value="{StaticResource CheckBoxColumnTemplate}"/>
                            </Style>
                        </Telerik:GridViewColumn.CellStyle>
                    </Telerik:GridViewDataColumn>
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="JobId" UniqueName="JobId" />
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="ConfiguredBy" UniqueName="ConfiguredBy" />
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="BuildLocal" UniqueName="BuildLocal" />
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="Copies" UniqueName="Copies" />
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="ParentId" UniqueName="ParentId" />
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="StatusId" UniqueName="Status.Description" />
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="QueueItemId" UniqueName="QueueItemId" />
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="ImportId" UniqueName="ImportId" />
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="QueueDescription" UniqueName="Queue.Description" />
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="QueueEnvironment" UniqueName="Environment" />
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="PrinterTray" UniqueName="PrinterTray.Description" />
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="Printer" UniqueName="PrinterTray.Printer.Name" />
                    <Telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="ReportService" UniqueName="PrinterTray.Printer.ReportService.Name" />
                </Telerik:RadGridView.Columns>

            </Telerik:RadGridView>

Hi NS,

I am not sure if you can do this from XAML (yet!), but you can define your columns in your code-behind. The idea is to add columns to the TableDefinition FieldDescriptors collection. Here is a sample:

GridViewTableDefinition definition = new GridViewTableDefinition();
definition.AutoGenerateFieldDescriptors = false;

GridViewDataColumn order = new GridViewDataColumn();
order.UniqueName = "ChildName";
order.HeaderText = "ChildName";

PropertyRelation relation = new PropertyRelation("Children");
definition.Relation = relation;

definition.FieldDescriptors.Add(order);

RadGridView1.TableDefinition.ChildTableDefinitions.Add(definition);

I am attaching a sample project that uses .NET objects with nested collections to define a hierarchy with custom columns.
