Cross Page question

Basically, what I am trying to do is send information via PreviousPage somehow, but can't figure out how. Let me explai:

On One page (FirstPage.aspx) I have a DataList(Id = "DataList") which contains Labels(Id = "Label") ImageButtons (Id = "ImageButton"). Now when I press an ImageButton with PostbackUrl to second page, I need a way to get the Text from the label, but from the label from the selected item.
I've tried:

                        DataList idDataList = (DataList)(Page.PreviousPage.FindControl("DataList"));
                        Label idLabel = (Label)idDataList.SelectedItem.FindControl("Label");
                        string id = idLabel.Text;

but I get null on idDataList.

Also read that you can put an OnClick event on the ImageButton and the server executes both OnClick and PostBackUrl, but in vain. I mention that OnCLick event is on server. My next try is to put OnClick on client with javascript and will post back. Thanks in advance!!!

yes, thank you for the reply. Using query strings is the best approach. Next step is to do this using javascript to avoid unnecessary page events. Now what I have in mind is:

give up labels and use ImageButton with onbuttonclick="" and get the redirect directly. Is this a good method?

Hi George
You can do it using ItemCommand event set commnadname property of image button
In itemcommnd event
Label idLabel = (Label)idDataList.SelectedItem.FindControl("Label");
If(e.CommandName=="ImagebuttonCommandName")
{
Response.Redirect("NewPage.aspx?Label="+idLabel);
}
In your new page pageload event
string labelvalue=Request.QueryString["Label"].ToString();
