Error Creating Control in design view #2

 Hi All,

 I try to use autocomplete with a textbox in vs2008 for a web application. I have included AjaxControlTookkit35.dll in my bin folder and I can also see it in the reference folder.

In the webconfig, I have <add tagPrefix="ajaxToolKit" assembly="AjaxControlToolkit35" namespace="AjaxControlToolkit"/>

 When I drop a textbox on the design view and "add extender" to add the autocomplete, I get the following error:

"Error Creating Control - TextBox1_AutoCompleteExtender

Failed to create designer 'AjaxControlToolkit.AutoCompleteExtender, AjaxControlToolkit35, Version=3.0.20229.26123, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' "

 However, I can still build the project and run it just fine even it is showing the error in the design view. Any suggestion?

If you are using VS 2008 SP1, then there is a bug

but I'm not sure if this is somewhat related to yours!!!  Can you try with other controls, do they give you the same error???

 Thanks for the reply. I haven't upgraded to SP1 yet, but just to make sure...this is what I see under "About Microsoft Visual Studio", Version 9.0.21022.8 RTM.

Also, all the AJAX toolkit control is giving me similar error, calendar extender, round corner extender...etc.

Error Creating Control
Very new to ASP.NET and VS so hopefully someone here can staighten me out.  I'm trying to convert some html templates we have over to the ASP.NET environment in Visual Studio.  I'm very used to Dreamweaver so not sure how this master page thing will work in my situation.  There are navigation items at the top like home - skills - services - clients, etc.  Then depending on what you select, the sub page will have nav items on the left.  So if you click services, the services page will come up with all our service options in the left nav.  I'...

"Error creating control" in design view
Hello, I have a page with some home-grown user controls and a 3rd party control on it and I changed a few colours on the 3rd party control. Now I get "error creating control" boxes in the design view for my user controls. The tooltip says it can't create the control "" - like as if it's looking in the 3rd party assembly to find my control. Why? What I am doing wrong? Thanks for any help, ..pd.

How Do I: (1) Show an image in the design time view of my control? (2) Have a controls property be a drop down list at design time?
I'm currently writing my first custom server control and could use a couple of pointers:First off I would like to have my control show an image in its design time view rather than the generic grey box with text in it.Secondly I have a property for my control that can be changed at design time via the properties menu.... at the moment the designer types in a value under the controls properties... I would like a drop down list displayed in the properties with all the available options in it, Any pointers in these directions would be greatly appreciated.    Cheers. ...

navigate from Edit control back to the view control when the view control needs parameter in the url ( ver 2.1.2)
Hi, I am writing a module for 2.1.2. The view control is loaded based on a "&itemId=" parameter appended to the url. The module has Edit and Add controls. I use the same ascx page for both (register the same page twice as Add and Edit). Navigation to the Edit is done by using EditUrl("itemId", itemId, "Edit") and navigation to the Add is done by using EditUrl("itemId", -1, "Add"). This goes well. The problem is going back from both Edit and Add to the view, when clicking update, delete or cancel. I've tried EditUrl("itemId",itemId, "") going back from the Edit, but I get the "mid=...

create webuser controls from html view not design view

Control design details and Collection items keep disappearing from VS.Net 2003 design view
This is a major nuisance. I don't know for how long, but for quite some time, I have experienced most (sometimes all) design work in certain controls like Farpoint Spread View, Component Arts Suite, DotnetCharting and possibly others simply vanish from VS.Net 2003. It seems to happen when switching between html and desing view, and/or when closing/reopening projects.I have contacted the different Component vendors, but according to them, this behaviour cannot be reproduced. Does it have something to do with a previous install of Whidbey Beta 1? Only yesterday I tried to reinstall VS.Net...

Can't drag any control INTO a view control... places new control at top right of design view.
VS 2005 created new web site.On default.aspx design view I added a Multiview control. I then added a View control within that.Here's the problem.  I can't place any controls inside of the view control.  If I drag a new button from the toolbox into the view control that I have in place, the button ends up in the top left of the design view. If I then Cut and paste the button into the View control, the button still ends up outside of the view control in the top left corner of the design view. What's causing this?  I have seen this done in many of the w...
