passing a token from pageA.aspx to pageB.aspx

[Jay]

I am trying to get pageA.aspx gridView to pass a key (say deptID) to
pageB.aspx which will use the value passed as a filter in it's own griView
query.
On pageA gridView I have a hyperlinkField with navigateURL property =
~/pageB.aspx?deptID={0} and it is bound to deptID (which is another column in
the grid). Also, the hyperlinkField it has its dataTextFormatString =
~/pageB.aspx?deptID={0}. PageB datasource has a where clause, where deptID =
{0}.
At runtime, the hyperlink appears to populate correctly with values such as
pageB.aspx?deptID=100, etc., byt when I click on it, pageB appears with the
token still set to deptID={0}.
I am new to webforms, can someone please help? Why doen't the
hyperLinkField pass the deptID value in the url token?
Thanks,
Jay

Apparently, you have two different "run" times here. One where the hyperlink
is properly filled in, and one where it goes to the wrong place.

Perhaps you're looking on the server at the hyperlink control when you see
the correct value? Well, the client has an HTML anchor (<a>) element
instead. You should try to find the <a> on the cliekt-side page using View
Source or the IE Developer Toolbar, and see what the href attribute is set
to. I bet it's set to deptID={0}.

Then, all you'll have to do is figure out why that is. In particular, I'd be
interested to know which property you're looking at on the server where you
saw deptID=100.

John, you were corect, when I looked in the html source, it had deptID={0}
for each row in the gridView. But I had set the hyperLink's dataTextfield =
deptID which is another column in the gridView. Shouldn't this bring in the
department IDs?

I don't know how this works with gridView controls, but that won't work with
a DataGrid. How is your data binding set up? Is deptID in the data source?

For data binding setup, I have deptID in the dataSource for the grid. I
click on the dataTextField property for the grid hyperlink, then select
deptID. I even tried a deptID2 to be sure, but the {0} never gets the data.
How is it that the {0} is supposed to get the values from the dataSource?
Also, if there is another way to do this (thru the desiger), I would be
happy to change to your suggestion.
Thanks
