cannot refer to data table

[Joe Au]

In the Page_Load event of web form, I create a DataSet and fill up by a
DataAdapter. Then I can retrieve data by the following command :
ds1.Tables(0).Rows(0).Item("accno")
However, when I issue the same command in DataGrid1_SelectedIndexChanged,
error occurs, Tables(0) cannot be reference. How can I fix it? Thanks.

Your dataset will need to get repopulated on postback if you want to access
it (or store it in a viewstate *shrug*)...

Where do you store the dataset?
How do you reference it from within the event?

Thanks to Karl and Miha. Karl is right. I populate the DataSet only when
the web form is first loaded.
