How to disable tree panel while data loading

[marxan]

Hello,

I've got a tree panel and a grid. When I tick a checkbox, data are loading into the grid.

I want to prevent the user to tick another check box until data are loaded.

I've tried to disable my tree component while loading, the component is in grey but you still can tick another box even if it is in grey.

Anyone has an idea how I could avoid that?

Thanks,

Regards,

What if you mask the treepanel's el?

treepanel.getEl().mask(); // unmask() to remove the mask once the load operation is complete.

Hi,

Thanks for your answer, unfortunately it does the same behaviour, I still can click on another checkbox while the component is grey.

I've finally found a workaround, I do a setVisible(true) of the treepanel and a setDisabled(true) of his main component. Now I'm sure the user won't click on anything.
