[CLOSED] mixed ext.net asp.net cotnrols and postback

[marco.morreale]

Hi,

I am using an aspnet datalist to place data in multiple columns.
I would like reading user values when user presses "send data" button but my datalist has no item on postback.

Is there a way to get datalist hold his values on postback? Is there a different kind of postback I can use?



Here is my code

markup

          <ext:Window 
            ID="wGrigliaPoteri"
