Templated Custom Control not updating host designer.cs file with child server control variables.
Hello, I have a custom web control that acts as a collapsable gradient header and containter all in one. I followed the MS example closly and got a decent control that works well. But then I ran into a problem, if I add another nested server control to the content area of my custom control on any given page, it doesn't add the protected cooresponding variabe in the pages designer code module. Below is an example of the problem, in the page TestPage.aspx the nested control "TextBox1" should show up in the TestPage.aspx.designer.cs but does not. I have a feeling that this ha...Custom Server Control with Child Controls
I have a custom server control <xx.Parent... /> which parses custom child controls <xx.Child... />. In Visual Studio 2008, IntelliSense shows me both when I start typing my control namespace. How can I prevent the child control from showing up in IntelliSense unless I'm adding it within the parent tags?Thanks. --Rudy...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...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...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...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 having a problem with the initialisation of a custom server control when it has controls inside an update panel, when its public properties are modified in the markup on the containing page.
In the code below, you can see that:
The server control contains a label, and exposes a public property, "Text", which simply wraps the text property of the label that it contains.
The page contains a server control, and modifies the server control's "Text" property through the html markup.
An "object is null" error occurs at line 7. The error can be fixed if eithe...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. 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?
