I have an strange problem on a TreeView. Some of the nodes are being populated dynamically setting PopulateOnDemand = true and using the corresponding method for the OnTreeNodePopulate event. Everything works perfectly on Firefox and Chrome but does not work on Internet Explorer.
It seems that callbacks for this node populations are not working on IE. My site uses .Net 4.0
how to show UpdateProgress content while PopulateNodesFromClient is going?

Two text boxes on a formview need to be prefilled with data (coming from session variables) on page load. The formview is in Insert mode by default. Is that the reason why it shows blank fields...
How do I get two fields filled in with data on page load.. the user will enter the rest of the fields and Click on Insert.
[Code]....
I put break points and saw that the data was coming in as expected...but when the page loads with formview, the text boxes do not show any data.
the page can be seen here [URL]
the client side validation is working for the adding date and time, but there is no validation firing for the count and room fields, I think i have coded them all the same, see sample for time and room below, maybe somebody see's something i missed? the validation group fires when the add button is clicked. also if possible I would like to get validation messages to appear in a validationsummary control that I already have coded and that is working when using the edit/update the rows presented with existing data.

Now, what happens is I get *all* rows from the DB, even though I specified only the top 10. The worst part is that if I run the query from the query builder, or even directly on the DB, it only gives me the rows I want. In addition, it doesn't sort :S
