How to load a user control dynamically in a page?
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.
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?
If i am loading control without if(!IsPostBAck) then its fine, but each time a page is posted loading of control is not good because it will slow my web site?

is there any particular setting in IIS for is there any particular method in classic asp for doing that?

View 3 RepliesI am working on a project which creates controls dynamically for a form in the page_load event, loads in their current values from the database and saves their values (using FindControl) when the user clicks the continue button. When I added a control statically in the .aspx page and followed their same procedure of loading the value in the page load and saving it on the button press I found that the value would not save correctly. It seems that it wouldn't save because the click event fires after the page_load, so the page_load of the post back reverted the value and the user entered value was not saved.
The strange thing is that by changing the control to be dynamically created just as all the other controls on the page and keeping the loading and saving the same it now works. Even though the page load still creates the control with the old database value. It seems like a very fundamental asp .net feature here but i'm just unclear as to what is going on. I suspect it is to do with the timing of creation and maybe when the view state kicks in.
I want to create a user control that will again contain a user control that will be dynamically generated and can be repeated N times with respect to data present in data table.
View 2 RepliesI work now in a huge project that we build all interface as Web User Controls .. every time I want to view & test one i should add it in web page and then view ..

Is it possible to develop such a thing ?
View 1 RepliesI am hosting a Windows User Control in my web page using <object> tag. Everything works fine when the control is outside the updatepanel and is independent of other web controls but when I move the control inside the update panel, it doen't load the user control properly.
<object id="myBrowser" classid="http:MyBrowser.dll#MyBrowser.UserControl1" height="20" width="400" VIEWASTEXT></object>
why it doesn't render the control properly and what can I do to fix it?
I tried moving the user control outside the update panel but since this user control is shown/hidden dynamically and is rendered based on other web controls which are inside an Update Panel, the user control is not shown at all.
