I have added new tab for ajax control toolkit ,
I can use for exemple AccordionPane control but there are some controls didn't work when I drag them in the designer view like "Calendar control and many ...." that ' s mean that this control can't be added in the designer
for mor information , I use Visuel studio 2008 and I installed AjaxControlToolkit-Framework3.5-NoSource.
I have an Error in the design view when I use the ajax toolkit. it says rendering Control Accordion - An unhandled exception has occurred. Collection was modified; enumeration operation may not execute. I have the relevant service pack, download ajax toolkit and I have used the appropriate declerations on the top of the page, I hope. I haven't yet even put anything on the page and the designer view shows the above error.

I'm working on a page that uses a master page. In the master page, I have a drop-down and when a value is selected I generate an evenIn the web page, I have this statement "Addhandler Master.FilterChanged, AddressOf FilterChangedFromMasterPage"Everything works fine, and can edit the page as much as I want, but only with the Source view - because if I look at the design view, the entire MainContent section is reduced to this error; "Error Creating Control- MainContent / Object Reference not set to an instance of an object"But if I debug it locally, or FTP it to the server, it works just fine!
View 1 RepliesI'm trying to develope a collapsible panel control with designer.
I have the following two classes:
[Code]....
and this one:
[Code]....
In fact, the designer class is a copy of a sample class in MSDN and I only tried to customize it to work for me. I'm not sure if all methods are necessary or not.
I have the following two questions:
1- When I use this contrl in design mode, I can add or delete controls to it, in the html view, tags are not updated. so when I close the page and open it again, all changes are lost.
2- I have added this control to the same asp.net project that is using this control. Isn't there any way to have this controil in tool box?
when I try to open the view designer in my windows application project I get an error msg - there is no editor available for 'C:documents and setting....Form1.vb' Make sure the application for the file type (.vb) is installed.
View 1 RepliesHow do i post html markup? instead of it showing as the controls that dont show on MY PAGE! I took the code directly from the sample website, i am not useing a master page so made a few changes. I cant figure what i missed i am guessing something to do with the commonpage that the page inherits from in the sample site or the fact that it had a masterpage and i didnt clean it up enough

It doesn't seem to matter what I try to make the animation do, I keep getting this shown in the designer. No one else on google seems to be getting that problem either. Note: it doesn't cause debugging or runtime issues... in fact, the only negative thing it does is make it extremely annoying when I look at the designer... I'm going to have about 12 of these updatepanelanimations firing everytime the timer ticks too :(.MasterPage file has the toolkitscriptmanager on it.Here is my designer code for the page I'm having the issue on:

This is my first silverlight Application. I am trying to use Rating Control from 3.0 Toolkit with VisualStudio 2008 Here are the problems: I am unable to see designer view after adding Rating Control and few other controls. I am not getting any errors or warnings on markup or while compiling. Trying to access Property window for any control is giving me this message " Property Editing not available". Is this the way silverlight was made available with Visual Studio or is there something I am missing here?
View 1 RepliesI created a custom server control. The control works perfectly when added into a project. The issue I have though, is that in the designer - it shows the error --> "Error creating control - MyControl1 Object Reference not set to an instance of an object" The error is because I am using this code to load startup scripts
Dim pg As Page = HttpContext.Current.Handler
if i comment it out then the designer does not throw the object reference error so I know this is where the problem is. So here is my question: How can I get the designer to ignore the HttpContext.Current.Handler object for rendering puroposes?

When I format an accordion control using a skin file (as opposed to entering the formatting as attributes on each <asp:Accordion> tag), the control renders as expected when the website is run. However, in the VS2010 designer, the control won't display but instead shows the generic "Error Rendering Control" box which hasthe exception, "Collection was modified; enumeration operation may not execute."

View 5 RepliesI'm just getting started in ASP.net and am building a site. I made a change to a style sheet to change the color of the links in my menu control on my master page. It looks great in the designer and is just the way I want it. Although, if I view default.aspx in the browser it is back to how it was before I made the change. Can anyone give me some suggestions on places to look to figure out why it isn't right in the browser?

View 1 RepliesI'm working on building a an ASP.NET composite control that is a wrapper for a GridView object. I have been able to figure out how compose the control in order for the markup to appear correctly when added to an ASPX page. Now the issue I'm having is that when I drop an instance of the control on a form from the toolbox, I can't interact with the control using the functionality exposed by a GridView (e.g. columns editor, data source selector, etc.), and I don't see any design-time rendering of the child GridView control. What I would like to do is to basically forward the designer behavior of my composite control down to its child GridView control. I have experimented with implementing a custom designer class that inherits from GridViewDesigner that simply initializes itself using the GridView child of my composite control. However, this doesn't seem to work, as I encounter an "object reference not set to an instance of object" error at design time; I'm wondering if this is even the appropriate strategy to achieve what I'm looking for. how to enable GridView-like design time behavior in composite controls. I have scoured the Web looking for articles on how this is accomplished, but I've surprisingly found virtually no resources on the topic.
