Hi,

I have a problem with getting the child row that is selected.

I have a grid with in the first column of the child grid a checkbox to select/deselect. When the check changed i handle the event. But i get the parentrow in the selected row and not the child row

How can i get the selected child row?

Little info on how i fill the childcolumn

    
              radGridResubmit.TableDefinition.ChildTableDefinitions[0].AutoGenerateFieldDescriptors = false;  
        
                                Telerik.Windows.Controls.UI.GridViewDataColumn desc = new Telerik.Windows.Controls.UI.GridViewDataColumn();  
        
                                desc.HeaderText = "";  
        
                                desc.UniqueName = "IsSelectedForResubmit";  
        
                                desc.IsAutoGenerated = true;  
        
                                desc.CellStyle = new Style();  
        
                                desc.CellStyle.Setters.Add(new Setter(TemplateProperty, FindResource("CheckBoxColumnTemplateAction")));  
        
                                radGridResubmit.TableDefinition.ChildTableDefinitions[0].FieldDescriptors.Add(desc);  
        
                                desc = new GridViewDataColumn();  
        
                                desc.IsReadOnly = true;  
        
                                desc.HeaderText = "ActionName";  
        
                                desc.UniqueName = "ActionName";  
        
                                desc.IsAutoGenerated = true;  
        
                                radGridResubmit.TableDefinition.ChildTableDefinitions[0].FieldDescriptors.Add(desc);

Hello NS,

Unfortunately our beta 2 ships with no public API that can return the selected child row in a hierarchical GridView. In order to get it you will have to use the GetParent() method of the VisualTreeHelper class. For example in your event handler you can use something like this:

    
            DependencyObject gridViewRow = e.OriginalSource as DependencyObject; 
        
            while (!(gridViewRow is GridViewRow)) 
        
            { 
        
                gridViewRow = VisualTreeHelper.GetParent(gridViewRow); 
        
            }

Now that you have accessed the selected GridViewRow you can use its DataContext.Data property to access the selected GridViewRow data.

All the best,
