Usercontrol vs Custom Server Controls, Any need for Custom Server Controls
Hello I'm new to ASP.Net so this is probably a stupid question but, is there any need to create customer server controls now that you can pre-compile usercontrols into a dll and thus easily share between applications? This blog post from David Ebb describes how to do it and the restrictions he note don't seem that bad (other than being able to embed resources such as images in the dll). http://blogs.msdn.com/davidebb/archive/2005/10/30/487160.aspx His article desribes the techniques for ASP.Net 2.0 and he suggests that there will be further improvements in .Net 3.5 in this ar...

Custom Server Control Vs Web Parts, Any need for Custom Server Control
Hello I've just posted a similar question on why you need server controls when you can pre-compile usercontrols and redistribute them. http://forums.asp.net/p/1397433/3010100.aspx#3010100 I've seen lots of (usercontrol vs web part) but not much on web part vs custom server control. According to the MSDN site you can put web parts onto a normal asp.net page outside of a web part zone and they behave just like custom server controls. So, if you are creating a bunch of controls for redistribution to customer asp.net sites and/or SharePoint sites why don't you just create Web Par...

problems listenening to events on a custom server control from another custom server control
 Hi all,I am having problems listening to events on one of custom server controls(AddBookmark) from another custom server control(BookmarkList). The listener or the BookmarkList control has a property that can be set to the AddBookmark control (string at design but the reference is obtained at run-time).

But the problem is that when the events on AddBookmark gets fired, the listener added from the BookmarkList is no longer present and the listene...

How to switch the visibility of a custom control while still get all the Javascript functionality included with that custom control?
Hello All, I have a custom DatePicker control which works well in the past non-AJAX aspx pages, and it also works in UpdatePanel as long as the initial Visible Property is set to true. But I need to set the initial Visibility to False, make it visible if user want to input a date (such as From XX Date To XX Date in a query ), and make it invisible if the user decide not to enter a date. It looks like the javascript used by the DatePicker control won’t be loaded if the initial Visible Property is set to False.  Here is the scenario: 1. Put a custom DatePicker...

Creating Custom Controls With Custom Controls Inside Of Them
Hello, I am trying to create a custom control for creating tabs. The idea is that our designer can just use the control tags to generate the tabs.  The problem that I am running into is that I want to be able to have a custom control that allows any number of child custom controls. So there would be a TabContainer Control, and within that there would be any number of tabs.  The idea is similar to how an asp:DropDown list can have any number of ListItems within them.  Here is my code, any help is appreciated. 1 <!-- TAB CONTAINER -->2 <%@ Control Language=&...

Custom Control within a Control Control
I am developing a custom controls that will render headers for different web sites. Within these controls, I want to place another custom control that will change the language.

Anyone have any suggestions? Thanks, ...

Get control type for custom control?
For basic controls (text boxes, etc.) it's relatively easy to test for their type.  but how do I reliably test for the type of a custom control?For example, I have a custom control called MyControl and would like to do something similar to this: If Me.FindControl(strControlToFind).GetType = MyControl.GetType Then ... Obviously this example doesn't work, as there is no GetType for MyControl defined.  Can I setup a Type for my control?  Or is there an easier way?  You could always try:If (TypeOf (Me.FindControl(strControlToFind)) Is MyControl) then ...
