    [CLOSED] Rowexpander Component Items update from Code-Behind

    Hi,

    In the following code there are 2 issues :

    1) I am trying to update txtName from code-behind. It does not return anything.
    2) I have checkbox selection model. I dont want checkbox to enable when I expand the Row.
    3) Click anywhere inside the expanded Row, and the Checkbox will toggle. Thus not allowing me to edit the textfield.

    Markup

    setting value in Page_load for txtName works... so guessing its something to do with BeforeExpand Event. Even Expand Event does'nt return any value...
