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...

Custom Web Control inside another Custom Web Control

I also created a custom webcontrol (CustWebButton) that inherts from Button control, and overrided the OnClick function.

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. ...

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 ...
