View Full Version : Master Detail Nested Grid

16 Aug 2010, 7:48 AM

I'm looking to create a master detail nested grid similar to one demoed below:
http://demos.devexpress.com/ASPxGridViewDemos/MasterDetail/DetailTabs.aspx (http://demos.devexpress.com/ASPxGridViewDemos/MasterDetail/DetailTabs.aspx)

I have looked at various options including the RowExpander and the live grid grouping examples. But I wasn't sure if these examples really point me in the right direction.

In short, how can one create a page similar to the one in the link above using Ext GWT?

Thanks in advance.

You can do this with a custom RowExpander. You will need to add widgetsupport to the RowExpander (there is already a userextension for this).

Wow, thanks for the super quick reply. Much appreciated, could you please point me to this user extension?

Thanks again!

You can look at this http://www.sencha.com/forum/showthread.php?76921-ExtendedRowExpander&p=424451#post424451

But you should not use it, as it leaks memory. You should fix it first.

Do you know a custom RowExpander, with widget support, with no memory leaks?
What exactly the problem with the current implementation?
Do you intend to support it as part of Ext GWT?
