İ downloaded gMap.dll and created an userControl which include Map.When i used this userControl in a aspx page directly there is no problem.But When i insert this usercontrol to page dynamically it only gives a gray box.This is my dynamically adding code
Control userControl = LoadControl("kcfinder/upload/userControl/googleMap.ascx");
userControlDiv.Controls.Add(userControl);
So, are some components not loaded with this method ?What is the problem?Thanks.
Add it in the Pre-Init method. Then refer to it as late as possible in the page life cycle, eg: Pre-Prender(...)

Started a new project and first created a MasterPage. Immediately I then created a ContentPage using MasterPage. I then realised I forgot to add ContentPlaceHolder controls in the MasterPage, so I added them. Rebuilding the project did not add these controls to the content page.
As it is a new project, I can easily delete the ContentPage and readd it, but for convenience in the future, especially for larger projects, is there any way to automate this process without having to recreate the ContentPage/manually type the ContentPlaceHolder controls within the ContentPages?
Thanks.
try this,
please have a look at below link.
1st Master Page is created and then it will be applied to aspx Page (ex: Default.aspx) once you applied the master page to aspx, what ever changes done to master page will reflect in the aspx page as well..

I am trying to use existing functionality which is embedded in a asp.net aspx page. So I have controls on this page and code behind for it. What is the best way to reuse this functionality in a new ascx control? Or do I just have to copy everyting into the control?
Can you not just take the controls you want to use from the aspx page and turn those into a control? Then you can use that control wherever you like.
To access the page parent just written this.Page in your control. But for access to these methods, you must apply an interface to the aspx page.
Senario: Masterpage with a UserControl and a child ASPX page
In the past when using this senario I've used an Interface as a way to pass a value from the UserControl (embedded in a
master page) to the masterpage code behind then consume that value in the child aspx page.
My question is now that asp.net 4 have arrived is this still a good way to achieve this or is there another or perhaps better way to do it?
I've read somewhere that perhaps "delegates" is perhaps another route to take.
Any help much appreciated

You could have your Masterpage inheret from a BaseMasterPage class that inherits from System.Web.UI.MasterPage. Then you can have a property on the BaseMasterPage. The user controls and child aspx pages can access the property by ((BaseMasterPage)this.Page).PropertyName
I am building a set of asp.net server controls and in one of them, essentially a container control, I want to add a form control, a script manager and an update panel. Is this possible or will I have to create these in a Page base class that I have for the web project for page/control life cycle reasons?
I am not using master pages.

ASP.NET allows only one form on the page. When you create controls, they are used on a page. You need a Page object to add controls to. This is why controls like the form and ScriptManager (who can only have one instance on a page) are put on the Page itself, or on the masterpage (if you have one). Putting them in a control would provide the opportunity to have two instances on the page, which would not work.
I'm using a Substitution control in my master page, and I want to render a user control content (related to the login area of my website) in the Substitution .
Seems like I must have a reference for the requested page so that it could render the control. But I need to render the control in the master page itself, as it's shared across multiple pages in my website. What are the guidelines to achieve that?
Tks
So you want to render a user control from your MasterPage code-behind, and add it to a Substitution that's also in the master page? Why do you need a reference to the page that's using the master?
Assuming your using VB and that I understand your question, try this in your MasterPage code-behind:
Dim someControl As MyControl = CType((New Page()).LoadControl("~/Path/To/MyControl.ascx"), MyControl)
mySubstitution.Controls.Add(someControl)
