I have a user control that will basically be a header in most of my pages, but not all. I want some code in the user control to be run before the page load event of the page that holds the user control, but the page load event fires before the events in my user control. Is there a way around this?
how to load user control dynamically on asp.net page? I am loading user control in my page_Init() event under if(!IsPostBack) but when user post the with any button click then my user control is disapper?

I have a page called "EDIT.ASPX" on that page it has come TextBoxes, Label and 3 User Controls. When the Edit.aspx page is loaded all the correction form Controls are loaded properly, even the User Controls loads with no problem. The problem that I am expericing is that on the User Control I have a CHECKBOX with AutoPostBack="true". Each time the user click the CheckBox the User Control disappear. NOTE: How do I fix this problem and eliminate my page control from vanshing. The user control needs to keep the same state as the Edit.aspx page when the checkbox is clicked. I need to be able to click the checkbox without loosing any data on the page rather it's the Edit Page or the User Control.

I created a user control, then use LoadControl to call the user control in a web form. Everything is working fine on my computer. When my work is copied to another developer's computer, the content of the user control does not show. All other pages are working fine.
The only difference I could think of between my computer and another computer is the other computer use ajax-created master page. But this web form that calls the user control does not use any master page.
I have an EDIT.ASPX page and on that page I have some labels and textboxes and a user control. I listed all the related codes you can have a clear picture - not all of the codes are given me a problem. ONLY ONE.
HELP ---> On the Uer control (SiteTemplate2.ascx) I have a DataList that is being populated by the database and that works fine. I have a CHECKBOX on the user control page each time the user check the CHECKBOX the user control content totally disappears from the EDIT.ASPX page. There is no error message -- I believe this is a post back error but I don't know how to fix it.
Goal: Each time the checkbox called (CHKBSideBar) is clicked on the user control page all of the page content should stay in place that include
EDIT.ASPX Page and the refeneced USER CONTROL. I should be implement a CheckedChanged Function without either of the pages lossing DATA. I need to be able to access post back event from the user control of the Edit.aspx page. When the user click a box on the user control page how do I keep the same Page_Load event on the edit page. I need to reference the Edit page from the user control.
Note: The edit page loads the user control (SiteTemplate2.ascx)SEE CODES BELOW
I know this is a lot and thank you in advanced for your help. I tried to include all the pages that are key players. I must user the user control bacuase the user can select different template so eliminating the user control is not an option.

I have a tab control on my page and on click of tab user control is loaded dynamically.I need to load the javascript file of that user control dynamically. I don't want to add the reference of my js file on parent page.so in my .ascx page load event i added:
Im working with asp.net web application,I need to get multiple gridviews dynamically based on the count (which i get from database) for that i took a web user control and i added a gridview there . iwant to load that usercontrol in aspx.cs based on the count..
Is there a way to instantiate and use a usercontrol (.ascx) if given you have its Type (ie. typeof(MyUserControl))?With regular asp.net controls like a textbox or a dropdownlist you can just make a new instance and add it to a controls collection. This doesnt appear to work for User controls. While you can make a new instance and add it to a collection, and have all of its events fire, it will not actually render to the page. Typically you would call Page.LoadControl() with the path to the .ascxThis presents a problem if all you have is its type. How can you get the path to the .ascx to give to the LoadControl method. Ideally I would also like to not have to have a reference to the Page object
I just want to call a user control using AJAX and get the rendered html of the control. However, when I try and fetch the control I get the following error message:
This type of page is not served.
Description: The type of page you have requested is not served because it has been explicitly forbidden. The extension '.ascx' may be incorrect. review the URL below and make sure that it is spelled correctly.
Requested URL: /Controls/ClientFormControl.ascx
Is it possible to make this type of page servable, or is there a specific way you need to call it? I know such things are easy in MVC frameworks...
Im working with Sitefinity and I'm developing a Control Designer - however i dont think my question is specific to SiteFinity.
I have a class such as:
public class CaseStudyFeaturedItem : CaseStudySelectorControlDEsignerBase
The class it is inherriting from is itself inheriting from UserControl, like so:
public class CaseStudySelectorControlDesignerBase : System.Web.UI.UserControl {
Within CaseStudyFeaturedItem is it possible to load a template which is an embedded resource and then access the controls on that control?
So essentially, I have usercontrol.ascx which is an embedded resource so has a string like:
mynamespace.myclass.usercontrol.ascx;
And from within CaseStudyFeaturedItem I want to be able to load that usercontrol and then modify the controls (i.e. literals/labels) that are within it?
I have this GridView that have it's DataSource as a list of previously selected products. For every item on it, I need to Eval it's ID and load a specifc form that the user must fill, then after that i've got to update the GridView.
I have made those specific forms as User Controls, is this the best approach for this scenario?
If yes, how can I dynamically load them, in a way that I can make queries/postbacks then update back my gridview?
I have a page that contains radioButtons. Each click on a radio button loads a user control (.ascx) in the page.
What I am doing is loading all controls at the same time, but set their visibility to false. When a user clicks a radiobutton I set the visibility of the specific user control to true.
As a result I am loading all the user controls on each postback.
Part of a web application we have uses an in-house web control assembly. This assembly contains several web user controls where several of these are used by other web controls within the same assembly.
The assembly is built as a website with a web deployment project.
The main web application's pages are dynamically compiled through a service into a single assembly and placed into the appropriate bin folder. In our development server the old assemblies aren't always tidied up and removed, meaning the folder gets full of old assemblies.
When the page that uses the in-house web control assembly (mentioned above) runs, the asp.net instance throws an out of memory as it loads all the old assemblies in an attempt to determine which assembly houses the reference to the user control being used by the other user control inside the same assembly.
We've been using the following inside the top level user controls to register the other controls
Of course when the application runs this gives no information as to which assembly it can find it in.
Is there anyone that's come across this problem before? It's not really a problem as our live servers use a clean up tool to remove old assemblies, but there are still potential situations where we could get out of memory caused by this (for example the tool stops working!), so it would be nice to resolve this problem.
