TreeGrid and ComboBox

[Urkman]

Hello,

is it possible to have a ComboBox in a column of a TreeGrid or perhaps of a ColumnTree?

Thanks for your help,

I think there is not a EditorTreeGrid in ExtJs but yes in ExtGWT.If you want a combobox in the treegrid you have to make a EditorTreeGrid extending of the TreeGrid.

Hello,

thanks for your answer.

I don't need a EditorTreeGrid, I just want do display a comboBox in a column.
Perhaps this can be done using a renderer or something else...

I need this to edit the rights in an application. My rights are displayed using a tree and each right can be "read", "read/write" or "none"...
So I want to display these comboBoxes and after editing is ready, I want to iterate over these comboBoxes and send the values to the server...

Greetings,
Urkman

Yes, you can render comboboxes to the nodes after they are rendered, but you have to watch for memory leaks (you have to destroy the combobox when the node is removed).
