Cant drag-and-drop Web Custom Control to Web Form!
Hi,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 s...

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? Thanks Hey, What do you mean by stops to work?  Explain what you are trying to do with it and what it doesn't do.Brian"Trust in the...

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 ...

Reusing custom web control in the same web control
Hello, I'm newbie in web development and of course asp.net. I am actually trying to build my first page and I'd like to know if it is possible to make a custom webcontrol that will contain itself. Let's say I want to draw a folder hierarchy in treeview-like structure. 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 http://thagen.dteam.info If the control can have child controls, then I s...

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.

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. ...

Add .Net Control to Web Custom Control
 I want to add .NET Control (like: TextBox, Button...) to Web Custom Control.How i can do it? Alphavn That's called a composite control -- "Mark As Answer" if my reply helped you -- Hello Guys What gunteman said, that is one approach and in most cases the right one.But its also possible to add child controls to a Control thats inherit from WebControl itself.
