[Solved] Binding data to a RadgridView on a Child

[Karim]

Hi, I have a WCF Service, my main grid is assigned thru 

ObservableCollection
<CRM_CommissionBuilder.CRMWCFServiceLocal.new_commission> commission = new ObservableCollection<CRM_CommissionBuilder.CRMWCFServiceLocal.new_commission>(e.Result.OrderBy(q => q.new_appid));

            rgvMonthlyCommission.ItemsSource = commission;

 however, I have child data for selected ids, i have created ChildTaleDefinition, 

<telerik:RadGridView.ChildTableDefinitions>

                           <telerik:GridViewTableDefinition />

                       </telerik:RadGridView.ChildTableDefinitions>

                       <telerik:RadGridView.HierarchyChildTemplate>

                           <DataTemplate>

                               <telerik:RadGridView  ItemsSource="{Binding _commissionEmployee}" x:Name="childGrid" ShowGroupPanel="False">

                                   <telerik:RadGridView.Columns>

 

                                       <telerik:GridViewDataColumn UniqueName="Name"  IsFilterable="False" Header="Name" Width="60" DataMemberBinding="{Binding new_employeename}" />

                                       <telerik:GridViewDataColumn UniqueName="Type"  IsFilterable="False" Header="Type" Width="60" DataMemberBinding="{Binding new_employeetype.Value}" />

                                       <telerik:GridViewDataColumn UniqueName="Commission"  IsFilterable="False" Header="Commission" Width="60" DataMemberBinding="{Binding new_commissionamount.Value}" />

 

                                   </telerik:RadGridView.Columns>

                               </telerik:RadGridView>

                           </DataTemplate>

 

                       </telerik:RadGridView.HierarchyChildTemplate>

The data for _commissionEmployee is for the child grid, however, nothing is populated for the child grid. 
Can I assign value to child grid thru code?  Please advice.  Thanks.

Hello,

Please note that the data context of the hierarchical GridView is the parent row. Is the _commissionEmployee collection available for the business object bound for the parent row?

You could also subscribe for the Loaded event of the hierarchical RadGridView and assign the ItemsSource there.

Hi, thanks for your prompt response.  _commissionEmployee is not part of the main grid, its another source, however, the grid datasource and _commissionEmployee share ID together.

Is there a way to connect thru an ID?

You mentioned about subscribing to the Loaded event, in the code behind, can I assign the itemSource property of the child gird, the name of the child gird is, "childGrid".  Thank You.  Karim.

Hi, do you have any feedback to my last response, any help is appreciated.

Hello,

As _commissionEmployee is not part of the main grid's bound objects, you cannot link through the ID property. You should specify a valid Source for the ItemsSource of the hierarchical GridView.

For more information on how to configure the Binding, please check this msdn article.
