I am using "MultiView", "GridView", "DetailsView" and many others controls in my page.I am also using session. when i run my page no problem happen. but after few minutes when i click any button (any postback) this error show :
"Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request."
pls help me. this problem also happen in my others pages.

This means that you are adding controls dynamically so that the control tree is different on postback.

Could anybody help me out what might be the problem.
I have developed an ASP Project using VB.Net 2005. Earlier the project was running fine with a SQL Server 2005 server that was installed in a different server. When i change the server to the local Server it is not running. If i run the project directly from the VB.Net environment it is running with an additional port address in the address bar of Internet Explorer. But when i try to run it derectly from Internet Explorer the firt page is displayed i.e., the login page. And when i click on the Login button it show connention not available.
Could anybody help me out what might be the problem.
Thanks in advance.

The problem is that your site ( which is NOT ASP, but ASP.NET, I am willing to bet ), is not configured to use the local SQL Server.

Hi I need some help with the drop down list in Visual Web Developer 2005. My problem is as such:
1.) I have a total of 50 categories in my DB.
2.) When I use a drop down list , it displays all 50 entries at once. I want to limit the number of displayed entries to 10, so that the user will have to scroll down to view the rest. Plus the fact that the 50 entries practically covers up 1/4 of the screen.
Please help.
Thank You.

You could try writing your own control that shows a scrolling div, I guess.

That's what I thought too, but I dun really have a idea of how to do it.

Yeah, it's a bit of work. You'd need to have the div, toggle if it was shown by a click, then set your textbox text based on a selection.

The way I'd do it is this:
write a base class for all your pages.
Add a property there that returns your specific Master page class, not the generic class you get from the base page.
To the master page, add a public propery to get the text from the textbox.
FindControl is just nastiness, why go searching when you can specify where it is ?

add this direcvtive in html

and you can access the master pages text box like
MasterPage pg = new MasterPage();
TextBox tb = (TextBox)pg.FindControl("Text1");

Can anyone recommend excellent courses, seminars, or training for ASP.net developers?
Our firm has a junior-level developer who has some Java experience and is learning C# and ASP.net on the job. But we'd like to make sure she learns smart practices and not just the standard Microsoft Kool-aid.
Who are the best companies providing courses & training?
Any recommendations would be VERY much appreciated!

You need to use URL rewriting to do this.
Don't you just hate coming up with something to put here?

hi friends..
i used the following code to disable the browser back button.
but its not working, until i clicked any button.
Code i used :
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Response.Cache.SetExpires(DateTime.Now.AddDays(-1))
Response.Cache.SetAllowResponseInBrowserHistory(False)
Thanks in advance..
cheers..

This won't kill the back button, it will just force the page to reload when you go back.
