I've made a web-application with 2 webforms, let me call them A and B

When A loads for the very first time a connection to a database is made, data added in DataSet, and some dataTables added to the DataSet
and everything is bound to a dataGrid
By clicking on some buttons, B is loaded, where i manipulate the data in the DataTables
Then there is a redirection to A again

There i just want to do a dataBind of the changed dataTables in my DataSet...

Which construction do i have to make for this situation
I've done smth like this code, but this doesn't work...
The part between If not ispostback then and else may just be done once, on the very first time

How can i do that?


For A:

Sub Page_load

        If not ispostback then

            ... 
            get data in dataSet
            add some dataTables
            Databind to datagrid
            ...           

        Else

        Bind dataGrid

        End if

End sub
