Usercontrol vs Custom Server Controls, Any need for Custom Server Controls
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...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). I am able to get a reference to the AddBookmark control and add a listener to it on the BookmarkList control on the OnPrender of BookmarkList. 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...Custom Server Control Vs Web Parts, Any need for Custom Server Control
I've just posted a similar question on why you need server controls when you can pre-compile usercontrols and redistribute them.
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...Custom Server Control Made of Custom Controls?

ASP.NET so rocks! Making page components extensible objects is such a great idea! I love it....Custom Server Control With Child Control
I am currently putting together a very simple control. The new control outputs a table with two rows. The top row contains a heading and the bottom row will contain any other content. The control as it stands works perfectly well and I can place text into the content row no problem.
Now, to the problem. Once I'd completed the control I figured it would be neat to enable the developer to add controls directly into the bottom row (content row) of the outputted table. As you probably know the WebControl class has a Controls collection which the developer can use to add any other...how to have both server controls and html controls rendered in a custom control?
I have a custom control in which there is an html text box.when you click on it , a div containing a table is appeared and according to what you select in that table a text is set to the text box.
It works fine but the problem is: as the text box is an html element it doesn't have viewstate and when a post back occures in the page its value disappeares.I tried a hidden field to keep its value.again there is another problem : I put this custom control in a usercontrol and put the usercontrol in a multiview and by clicking on a button this view is selected and by clicking another bu...How do you expose the event of a child server control from within a custom control?
I am trying to create a custom control that has a server control (dropdownlist) as a child. I need to be able to expose the selectedindexchanged event from the dropdownlist at the page level. How do you do this? Here is a quick abbreviated example I wrote to show what I am trying to do:

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. I created the language control and had it implement IPostBackDataHandler. This control works fine if I drag it on a new web form, but if I tell a header custom control to render it problems occur. The Language Selector custom control does not have a Page member anymore and the event handlers do not work. Does anyone have any experience with doing something similiar? Anyone have any suggestions?

Hi, I am having a problem in using server controls in ASP.Net, with C#. I am trying to create a server control which contains 2 other server controls that I created (Called MyImageButton).

I'm working on creating my own customized datagrid control.

...load user control from server custom control
hi all,i have a 3rd party menu control that consists of a bunch of HyperLinks and a PlaceHolder control (C# v1.1.4) . links to .ascx files are retrieved from a data source, and when the page containing the control is loaded or a link clicked, the control uses this.Page.LoadControl(strLink) to add the .ascx to the PlaceHolder. fine and dandy, probably wouldnt have done it that way myself, but i'm stuck with it :)the problem is events: i can't raise 'em :( if i have for example a Button control on one of the .ascx pages, the Button.Click will go by unnoticed on the post-back. stran...Using a server control in the rendering a custom control
I have a custom control that overrides the Render method to draw itself. Is it possible to use a server control (asp:Image, wwHoverPanel, etc.) inside such a custom control or would I have to rewrite my custom control as a composite control?
I'd like to do something something like:protected override void Render(HtmlTextWriter w)
// somehow place asp:Label here
w.RenderEndTag(); // column
w.RenderEndTag(); // row
