I just installed Ajax Toolkit. The controls are available in my Toolbox, but when I insert them in a page, Visual Studio underlines them with the error message "unknown server tag".
I googled the problem and found several ideas :
check if the DLL is in Bin folder check if ajaxToolKit tags prefix is registered in web.config and make sure I'm not using a different prefix in my pages check if the DLL is registered in the pages with <% @ Register ... %>
Unfortunately all of this is fine, but I still can't get the controls to work. Is something else missing ?
EDIT : My environment is ASP.Net 2.0, Ajax Extensions 1.0, Ajax Toolkit 1.0.20229, Visual Studio 2005
I have got an error "server response error : Unknown server error" while uploading file using Ajax AsyncFileUpload, code behind function is triggered while uploading, but after code behind function executed, we are getting this error.
I am Getting the following error using the Numeric UpDown Control from Ajax Control Toolkit. Assembly 'AjaxControlToolkit, Version=3.0.30512.20315, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' contains a Web resource with name 'AjaxControlToolkit.NumericUpDown.NumericUpDownBehavior.debug.js', but does not contain an embedded resource with name 'AjaxControlToolkit.NumericUpDown.NumericUpDownBehavior.debug.js'.
I'm building a dynamic form using XML and XSLT. Anyway I'm using a custom asp.net control for CKEditor, it's an HTML editor.
When I try to add the controls from the XSLT using Page.ParseControl(<the-string-from-the-xslt-here>), I get a warning saying:
Unknown server tag 'FCKeditor.CKEditor'
And of course, if I remove the control from the XSLT everything is working fine and all the regular asp.net controls like TextBox etc get rendered to the string just fine. Does anyone know what I can do about it?
I don't know what is going on. When I try to add a tab container in my page, it allows me to do that but when I modify the code, the unknown server tag error pops up in the design view of the page.
I checked the source code to see if I had my @register clause in there, and it was there, but still the error shows. I don't know what happened, the last time it worked perfectly.
I have also recently downloaded the cute editor for .net and installed the .dlls to my bin folder and it is showing the same simtoms as well.
In my application i use iframe (to be more specific; Greybox tool). Sometimes i had an unkown error when i open page in iframe. Then i applied this fix : [URL] and that unknown error disseppeared. But i have another problem now:( I am using following script to focus to the first textbox whenever my input pages are opened in iframe.
aField = document.getElementById('txt_PID');setTimeout("aField.focus()", 50); After i applied previous fix, i get this error when i load page in iframe for the first time :
Can't move focus to the control because it is invisible, not enabled, or of type that does not accept focus. Here, txt_PID doesnt contain any ajaxtoolkit things. (also Enabled= true and Visible=true etc.) . Last thing, my current test page contains just 3 controls: txt_PID just plain Asp.TextBox ajaxHTMLEditor another textboxt with MaskedEditExtender. If i remove HTMLEditor from page; i dont get that error( Can't move focus...) and also i dont get first error which i applied that fix in toolkit.
