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...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

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...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 Made of Custom Controls?
I'm giving myself a crash course in custom server controls, and I have a quick general question.
Can I have a custom server control that is composed of other server controls I created.
I'm pretty sure the answer is yes, but I want to be positive.

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?

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

I have two individual custom controls say custom cc1 and cc2. cc1 is communicating to cc2 using event delegate mechanism.I have tested the behaviour by dropping cc1 and cc2 onto a Web Page and it works fine.

I'm a little new to server controls so this question may seem silly, but has anyone had trouble with events from custom server controls that are embedded in other custom server controls?
I'm trying to create a composite control that creates a list of items and creates an instance of another composite control for each item. So for example the list could be a collection of addresses that has an editor composite control for each item.
The editor composite control allows the user to edit the item and click on a save button. This works fine if it is on it's own (ie not part of the list ...How do you expose the event of a child server control from within a custom 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...
