I have two identical pages that list out the contents of two different folders with hyperlinks to each file. One works, the other doesnt. On the one that doesnt I get this error:
"Control dgFiles__ctl24__ctl1 of type DataGridLinkButton must be placed inside a form tag with runat=server"
There are 29 files in the folder with the page that doesnt work. If I set the page size to "20" I get the error above, if I set it to "15" I get the same error but the Control is dgFiles__ctl19__ctl1. If I set the page size to "30" (one more than the number of files in the folder) - it works.
The other folder with the same type of page has hundreds of files in it and the paged datagrid works fine. I dont get it.
Here is all of my code:
Code:
<%@ Import Namespace = "System.Web" %>
<%@ Import Namespace = "System.Data" %>
<%@ Import Namespace="System.IO" %>

I dont see anything glaring other than you arent accepting the changes on your dataset or disposing your resoruces, but nothing that glares at me as something that would cause the problem. Maybe try accepting changes at the end of your custom Fill method you wrote... also trying doing an indexed loop instead of a for each and see if that is causing some sort or reference issue - shouldnt be, but Ive seen stranger.
