Visual Studio :: Unable To Add Custom Control To Toolbox
Jul 20, 2010
I have project A, which is a class library project. I compile it and it creates a dll. In my project B which is a web application project, I add a reference to the A.dll, and I click on toolbox and select choose item, navigate to dll, and click on it. The control does not show up on my toolbox. When I right click my toolbox and select "show all", the control is there, but it's grayed out. I have been searching for an answer to this for a couple of days now, nothing changes.
I have developed a User Control in inline code model and convert this into dll and try to add it into Visual Studio ToolBox. It shows error "There is no component found in the object.". It is showing actually because i have not added ToolBoxData attribute just before the class declaration, because there is no class declaration in the inline code model. I don't know where i have to add ToolBoxData attribute.

I'm using Visual Studio 2008 SP1 for ASP.NET 3.5 development.But the SqlDataSource control is not visble in the Toolbox - Data section.When I drag in a GridView control, the smart task list asks me to configure the SqlDataSource control, so it is "in there somewhere"
I have a simple HttpHandler that generates a dynamic image based on query string parameters and a custom web control that renders an image tag pointing to the handler as its 'src' attribute. All works fine when run in the web server, but at design timethe control displays as the "missing image" icon (red x in a box). The handler is registered in the web.config with a ".ashx" extension. The RenderContents method in the control looks like this:

I notice when I create a project the common controls menu which includes the webbrowser control is available. When creating a web application in either vb.net or c# the controls are NOT available. Why is this? How can I get them to appear in my web application. I want to use the webbrowser control in vb.net .

I have vs08 running on window 7 which comes with .net 3.5 SP1. how can I add the new feature that comes with it to my vs08 toolbox. I am assuming sp1 is the same as 3.5 extension.
I am trying to use one of the componets of the WPF Toolkit,[URL] but when I look for the component in my Toolbox it's not there, so when I set the Toolbox to ShowAll, the components are listed but they are grayed out. I right click on the Toolbox > Choose Items and look for the component in my list and ensure that the component is selected, but it still shows up as grayed out. If I turn off ShowAll the components are not listed. How do I get these grayed out components available for use?
My toolbox has begun filling up with duplicates of the controls. A set of controls under a standard tab may be repeated as many as two dozen times. This is driving me crazy. I tried reseting the toolbox (which required me to reinstall the two cusom tabs I had), but that only reduced the number of duplicates--it didn't entirely eliminate them. Also, I keep getting a strange, orphan tab created with the label "#13119" . It has no controls, and I can't delete it, and it didn't go away when I reset the toolbox. It almost seems like it's adding another set of controls every time I open Visual Studio, or perhaps every time I reopen my project.
