hello,
On page load event i am generating a report in an aspx file and then
capturing the html and saving it as html file to be sent as emil attachemt. This has to be done multiple times for different users.
I am overriding the render method of the page to get the html. It works okay for the first time but i need to create the report multiple time. When the below code is called for second time on page load event to capture the newly created report, it gives the error '"A page can have only one server-side Form tag"'. Following the code.

Dim sb As New System.Text.StringBuilder
Dim sw As New System.IO.StringWriter(sb)
Dim hWriter As New HtmlTextWriter(sw)
MyBase.Render(hWriter)
' *** store to a string
Dim PageResult As String = sb.ToString()
' *** Write it back to the server
writer.Write(PageResult)
str = PageResult

i get error on MyBase.Render(hWriter). Remember its working okay for the first. So how can i get the html of the page multiple times????
Thanks,
Safvi

Don't post the same question (even if you change a few words) more than once.

It depends on what browser you are using. If its IE8 hit F12. For earlier IE versions get the developer toolbar.

Yes, you can get IE developer Toolbar http://www.microsoft.com/downloads/details.aspx?familyid=e59c3964-672d-4511-bb3e-2d5e1db91038&displaylang=en[^]

Or can view the source of page and search for the control.

What do u mean by embedding? Do u mean creating a PDF file on any user control event. Like Print button, when hit should create a PDF control.
Let me know if i understand you correctly

Just use <iframe src="yourPDFfilenamewithPath.pdf" width="500" height="500" /> and the web browser will automatically load the pdf in the iframe.

or you can create a user control[^]

Maintaining Scrollbar Position and Div Tag State on PostBack

Hi
I have a web page that regularly refreshes on post back, and all of this works fine.

However, a user has made some suggestions to enhance the page, which I need some help with:

1) There are 3 asp.panels on the page, which are scrollable vertically. When the page refreshes, the scroll position returns to the top. The enhancement is to maintain the position of where ever the scrollbar is on postback. How do I keep the scrollbar position on post back?

2) Within each of the panels are dynamically added web controls. These web controls contain gridviews, which are themselves contained inside div tags. These div tags can be hiddened and made visible by an image button. This hidden and visible state is actioned by some javascript on the page. Again, the user has asked how it is possible to maintain the state of these div tags on post back, i.e. those that are closed and those that are visible. Currently, the state is on postback for all the div tags to be visible. How do I maintain the state of the visibility of a div tag during postback?

Thanks

You need to enable smart navigation and maintain scroll position on your page such that after complete postback it maintains the scroll.
If its a AJAX requst then you need to handle it in Ajax BeginRequest handler and EndRequest handler, where you track the scroll position before partial update and restore it after partial update is complete.

In order to maintain the states of Div tags, you have to maintain 'hidden' field. Update the hidden field and store the values such that you can track which div tag needs to be visible. Restore the state of div tag during postback based on the hideen value field.
