I have a simple program. On the left I have a tree view (obout) very good by the way, and a grid on the right.

In my cs file, I wrote a class for the grid. I pass a value and the grid is populated.

When I click on a "leaf", I want to reopen the grid with the value of the "leaf".

When I click on a "leaf" the control is back to javascript and I have the value of the leaf.

My question now is how can I call the class from javascript ?

Also is there's another solution ?
