[Solved] Cannot set focus on child Grid when expand second time (scenario of hierarchical RadGrid).

[Manas]

Hi,

 

I have hierarchical Grid View (Parent and child grid), child grid allows user to enter new row by hitting <INSERT> key. Child grid bind with Loaded event (Loaded="RadGridView_Loaded").

 

When load control first time and expand any parent row by click on pulse (+) sign then fire child grid Loaded event and set focus on child but if I collapse parent row and expand again then does not fire Loaded event, so I can’t set  focus on child grid to add new row by hitting <INSERT> key.

 

If anybody has any way out regarding that, then please guide me.

 

 Thanks.

 

Regards,

Manas

Hello Manas,

I may suggest the following approach :

Subscribe to ExpanderRowStateChangedEvent the following way:

this.AddHandler(GridViewExpandableRow.ExpanderRowStateChangedEvent, new RoutedEventHandler(OnExpanderRowStateChangedEvent), true);

This event will fire after the user has pressed the expand button .
Within the event handler you may get acces to the expandableRow this way :

void OnExpanderRowStateChangedEvent(object sender, RoutedEventArgs args)
        {
            GridViewExpandableRow expandableRow = ((RadRoutedEventArgs) args).Source
        }

After you have got the reference to the expandableRow , you may manipulate it the way you need.
