Cant drag-and-drop Web Custom Control to Web Form!


I'm going insane here, I've read countless articles how to create a Web Custom Control and add it to the Toolbox and then just Drag-and-Drop it to a Web Form.

And I have done exactly that except for the last step, any Web Custom Control I create refuses to be Drag-and-Dopped to the Web Form.

What happens is the following, after I have added the Web Custom Control to the ToolBox I click it and drag it to the Web Form designer area. First I can see the icon of the Web Custom Control and I see a Referance being created but just after that the icon changes to one of those "you cant park here signs" (round circle with a line across from top right to lower left) appears and does not allow me to add the control to the Web Form?

I've checked the HTML section of the Web Form and nothing is added there, but I can if I like add the control in code and it will show up after I build the project, but refuses to be bound to the Designer so that I can tell it where to display the control if created in code it always displays in the upper left corner.

I have tried everything I can think of and even compiled projects I downloaded to get it to allow me to Drag-and-Drop the controls and it just wont let me. The example project compile without a problem and the Web Custom Controls can easily be added to the Toolbox but cant be dragged onto a Web From.

I even created a new Web Control Library and changed the inheritance to inherit the DataGrid Web Control and removed all other code which should mean that my new Web Custom Control is a clone of the DataGrid Web Control and it still didnt work.

Is there anybody that has experianced this behaviour before?

Or am I doing something wrong?

Ok this is what I have found out so far after looking into some alternats.

I have a laptop so what I did was installing Visual Studio .NET 2003 on it and made a simple Web Application project and a Web Control Library - compiled the Custom Control and added it to the Toolbox and drag-and-dropped it to the Web Form without any problem.

So basically on another system I dont get the same problem so I guess the problem has to be system specific, so the following is my setup:

OS:           Windows Server 2003
Services:   Terminal Services, SQL Server 2000, IIS 6

The biggest differance is of course that I use Terminal Services to login to the server, I dont know how much this could have to do with it but seems very wierd as everything else works perfectly. Also recently I migrated from another server with the exact same setup and on that Server the Custom Controls could be dragged to a Web From.

I guess the question is what the designer in VS is doing when a Custom Control is dragged to a form, is there any security involved on the IIS?

Also to end my post here I have re-installed Visual Studio from scratch, now I'm just in the process of re-installing the IIS services.

Let see if that helps as re-installing VS didnt help.

I would appriciate any input no matter how crazy it might sound. :o)

I cannot drag web custom controls from toolbox to web form
I have created some web custom controls (both composite controls or derived/inherited controls).  I successfully added them to the toolbox. However, when I try to drag them onto the form, the cursor changes into a black circle with a diagonal line, and cannot drag them.  I also tried double-clicking them from the toolbox but it still won't work. I sent the Control Library (DLL) to a friend, and he managed to use it properly.  I am assuming this is a problem with my Visual Studio. Has anyone encountered such a problem?  Any suggestions or solutions?   Thanks. I...

Custom Web Control inside another Custom Web Control
Hi I created a custom web control (CusWebNew) that displays some textboxes by adding them to the ControlCollection of the webcontrol. I also created a custom webcontrol (CustWebButton) that inherts from Button control, and overrided the OnClick function. When I use CustWebButton on a regular web form, it seems to function correctly. However, when I added to be part of the ControlCollection of CustWebNew, it stops to work.   Any ideas why?

I thought I could make a control that will display a folder and if this folder contains subfolders then for each the control will include itself. Is this even possible? What would you suggest me to do to? Thanks in advance. TomTom Hagen If the control can have child controls, then I s...

Controlling web control instances on Web Form
I have created a composite control, extending functionality of the Hidden Control. However, I would like to prevent the user from adding this control to the page multiple times. I only want one instance of the control on the Web Form. What setting in my project to I adjust to enable this functionality? I can not find it in any of the books that I have referenced. Is this a setting or is this code that has to be added to the inheriting class. Looks like there is no standard apporach. But I'd consider using static field to count number of created objects and throw exception if second object ...

Server Web User Control or Web Custom Control
Ok, I made a DataGrid I like, stuck it in a Web Control Lib, and then to my toolbar. Now I want to take my nice little control and add it to a greater control, maybe place some buttons around it etc. I could always inherit from it in a new custom control and dynamically add the buttons, but I thought about using a Web User Control. I thought I could easily create a Web User Control, drop on my grid and the buttons on a form, and expose some properties and events, but once I got into it, I got a feeling that this isn't what a Web User Control is for. When designing a control li...

Use Web Custom control or Web User control?
Friends,  I have a generic aspx page and its functions which is used in many .NET web application. The generic page contains a HTML Div control, server drop down list, server buttons, server textbox and it have different server and client functions to do its tasks for calling aspx pages in web applications. My problem is I do not know whether I should make that generic page as a web user control (but this is tedious because all other application folders must store frontpage aspx and code behind files of the generic page) or as a web custom control (This seems to be good beca...

Web control in web control
Hi,There are two simple web user controls A and B, where B contains A. They just display the bunch of text boxes, so I do not need them even in tool pane. They sit in the same project next to web form.I noticed that web user control put on ASPX page does not appear in code behind, but if I create it with protected keyword and name being exactly the same as id it works fine. I can access such a web control from code behind and see the value assigned in IE. The problem is that the same routine does work for my A web control in B. When I assign the value IE, I keep getting null reference. ...
