Datagrid blank on postback.

[SatishPasala]

Hi

I tried all the things I know am out of ideas now. Can you guys help
me out with this?

I have 4 grids on a page with I load on the Page_Load event. One of
the grids has paging. When I move to different page on one of the
grids, all the other Grids loose data on on postback.

I am binding all the grids on the Page_Load event of the page the
grids are in for each postback.

Does any one have any idea what I am missing?

Which version of DotNet are you using?
Are you using custom paging?
If so, they're not using the same event handlers, are they?

I am using .NET 1.1. I am not using custom paging. I debugged through
the code.

I see the dataview is assigned to the datasource of the DataGrid and
BindData() method being called.

I dont see the data in the grid except for the headers. I also
confirmend that there is data in the dataview that is being assigned.

I am not able to pin point where the error is.

The datagrid is in a user control. If it makes any difference.

Since you're saying the DataGrid is in a User control, you have 4 user
controls on the page, each of which has a DataGrid in it, right?

Do the datagrids share any information with one another (do any of them rely
on one or more of the others)?

All of them have different information from different sources. They
are independent grids and do not share any information. I have paging
enabled in one grid. That particular grid works fine when I page to
different pages. For the first time !IsPostBack all the grids display
data properly. They only go blank when I click on a different page on
the datagrid.

Studio 2003 has a tendency to remove the event registrations in
InitializeComponent() method. I checked this method too to make sure
the event registrations are present.

your paging logic might be repeated?

So if you go to page 2 on AAA.aspx, then go to BBB.aspx the grid looks
for page 2 but only has page 1. happens when you use common session
variables. Try using a ViewState variable instead.

Just a guess.

All the girds are on one page. Paging is referenced to datagrid
paging. I am loosing data on the postback.
