Having a bit of trouble here. I know that if you want to use a fileupload control inside an AJAX update panel then you need to create a trigger for the control that performs the uploading postback to the updatepanel, but the problem is, I have an update panel that contains web usercontrols. I therefore can't add a trigger to the control(FileUpload) directly because it exists in the web control.

This control works fine in a normal page, but once I put it inside an update panel it doesn't work. Is there a work around or simply I can't use JQuery inside update panel?
I am hosting a Windows User Control in my web page using <object> tag. Everything works fine when the control is outside the updatepanel and is independent of other web controls but when I move the control inside the update panel, it doen't load the user control properly.
<object id="myBrowser" classid="http:MyBrowser.dll#MyBrowser.UserControl1" height="20" width="400" VIEWASTEXT></object>
why it doesn't render the control properly and what can I do to fix it?
I tried moving the user control outside the update panel but since this user control is shown/hidden dynamically and is rendered based on other web controls which are inside an Update Panel, the user control is not shown at all.

View 4 RepliesI have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)

I have a webpage which I would like the ability to upload files to be stored in a database. Here's the layout of the page:
[code]....
The update panel is configured as such:
ChildrenAsTriggers="True" EnableViewState="True" RenderMode="Block" UpdateMode="Always" Visible="True" Runat="Server"
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.
