Need help with storing dataset in session variable

I have developed a windows application in VB.NET and now want to take parts of it and put it on the web, so although I understand all about datasets etc, I know little about web development

My issue is that I have a grid bound to a dataset, and I have a text box under the grid where users can enter a new value. They then click the ADD button and I want the result to be added to the dataset and thus appear in the grid. When the user first opens the page the grid is empty. Unfortunately each time I add a new item, it forgets all the other items that have been enetered so I can only ever have one line in the grid

I know that I can store a dataset in the session by using Session.Add but how can I firstly make the grid use the session variable as its datasource and secondly how do I add or modify the dataset stored in the session variable

Any tips, or advise would be much appreciated.
 
you will have to do that in code

not tested but should be somthing like this

in the page load

ds = Session.Item("yoursessionDS")

DataGrid1.DataSource(ds)



hope it helps

Because I thougth someone has once fight with that never forget anymore
DataGrid1.databind after that (not that I know where it is for, however when
you forget that it does nothing)

(Not important, just some prickling however it missed because you did not
use that datatagrid, I expected you would see that direct).
