    Hello I am having one issue on RadGrid. I have a simple Employee list which I am binding in Page_Load inside !IsPostBack check.

    As soon as, a postback happens (whether it is due to a button click or due to allowsorting (automatic sort)); the grid disappears. This is because NeedDataSource is not executed on postback.

    However, if I write RadGrid1.Rebind() then NeedDataSource is executed.

    Does this means everytime when a postback happens, I have to call RadGrid1.Rebind() to bind the grid (whether it is due to a button click or due to allowsorting (automatic sort))?

    I remember in earlier version we did not needed to call Rebind() method to make NeedDataSource execute.

    Please help.

    Hello Johney,

    When using advanced data binding through NeedDataSource you do not need to bind the grid initially on Page_Load event handler. I would recommend you to check out the following help article which elaborates more on this binding type.
