RadDragDropService for ChildGrid in RadGridView

[Vincent]

Hello,

 

I have a RadGridView built with a relationship like that

GridViewTemplate childTemplate = CreateChildTemplate();
            m_testAlarmLibRelation = new GridViewRelation(this.gridTest.MasterTemplate, childTemplate);
            m_testAlarmLibRelation.ChildTemplate = m_alarmTemplate;
            m_testAlarmLibRelation.RelationName = "TestName";
            m_testAlarmLibRelation.ParentColumnNames.Add("Name");
            m_testAlarmLibRelation.ChildColumnNames.Add("TestName");
            gridTest.Relations.Add(m_testAlarmLibRelation);
            
            RadDragDropService svcTest = gridTest.GridViewElement.GetService<RadDragDropService>();
            svcTest.PreviewDragStart += svcTest_PreviewDragStart;
            svcTest.PreviewDragDrop += svcTest_PreviewDragDrop;
            svcTest.PreviewDragOver += svcTest_PreviewDragOver;

I get the service on the main grid . But it doesn't work.

How can i access to service on childGrid ?

 

Thanks.

Hello Vincent,

Thank you for writing.  

Please refer to the following help article demonstrating how to achieve drag and drop functionality in RadGridView: http://docs.telerik.com/devtools/winforms/gridview/rows/drag-and-drop

Note that the service is started on mouse down left which is handled by the GridDataRowBehavior. Depending on the row type RadGridView uses different row behaviors. Additional information is available here: http://docs.telerik.com/devtools/winforms/gridview/rows/row-behaviors

I have attached a sample project for your reference where the drag and drop operation is started from the master and child templates.

I hope this information helps. Should you have further questions I would be glad to help.
