how to make SynchCallback<T> , i need to make RPC before render .
Because if i use AsyncCallback<T> after the render of the grid and display the value (which is wrong), the value of the RPC (right value that i need) returned and i can't use it any more .

There is no build in way in GWT to may a sync rpc call.

What is the exact need for a sync call? I only know of one and thats probably not the one you have.
