Using a user control in a custom server control.
I've created a custom server control and am trying to add a user control to the rendering of the server control. Is this possible? If so, hints as to how this is done would be GREATLY appreciated! Thanks in advance for considering an answer to this question.
Use the LoadControl method. For example: Controls.Add(LoadControl("~/controls/login.ascx"))Steven BeyRecursion: see Recursion
My server control renders a table with x number of rows. I want to add a user control to each row of the table, last column. I do not know how ...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?
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 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...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
...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 ajax control (CollapsiblePanelExtender) in custom server control
I'm trying to write a server control that contains the collapsiblePanelExtender from the ajax toolkit. But I have the following error when i try to show this control:
Extender control 'ctl00$contentHolder$ctl00$Ant_baseModule1_cpeDemo' is not a registered extender control. Extender controls must be registered using RegisterExtenderControl() before calling RegisterScriptDescriptors().
I have no idea what i must add or change to make it working. Anyone who has an idea? Or maybe I'm doing it all wrong?

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.

Can we use the existing ASP.Net Server Controls to create Custom Controls?
I am able to use HtmlTextWriter to make my Custom Controls. I want to be able to add regular ASP.Net server controls to create my Custom Controls. Is this possible? Can anyone provide a sample?
Basically, you just need to inherit the control you want to use, like this:
Public Class MyControl Inherits System.Web.UI.WebControls.TextBox
Then you can override the methods you want and add code as needed.

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.

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 do I use an embedded resource image in an imagebutton control in a custom server control?
I have a custom server control that I am building that includes an imagebutton control. I want to be able to use an image that I have included in the control as an embedded resource. Am I missing something here.... How do I get the imagecontrol to use the embedded resource image instead of the imageurl? Note : I'm still on 1. - not 2. yet....I build the the image control as follows....
