Controlling web control instances on Web Form
I have created a composite control, extending functionality of the Hidden Control. However, I would like to prevent the user from adding this control to the page multiple times. I only want one instance of the control on the Web Form. What setting in my project to I adjust to enable this functionality? I can not find it in any of the books that I have referenced. Is this a setting or is this code that has to be added to the inheriting class.
Looks like there is no standard apporach. But I'd consider using static field to count number of created objects and throw exception if second object ...controlling an object in a web control from the page the web control is placed in
I have created a web control in vb.net that has an image button and an image. when it loads the image button is visible and the image is not.
I want to be able from the page which "includes" the web control to set the image button to invisible and the image to visible.
When I tried this, the main page didn't recognise the image button or the image (both < asp: objects).
help would be gratefully appreciated.
oh yeah, it's inline code so any code behind stuff will just confuse me ;)

Below is a block of code in my .aspx form named default.aspx. In this form I load a web user control. I then add it to a place holder control.(Lines 3 and 4 below) So how do I access the individual controls in my web user control? I want to set the properties on those controls, but I am baffled as to how to access the control. For example I have a text label control named "label3". How do I access this control.
Because for example, under certain situations I want to hide that control. ( Label3.Visible = false;)

Hi,There are two simple web user controls A and B, where B contains A. They just display the bunch of text boxes, so I do not need them even in tool pane. They sit in the same project next to web form.I noticed that web user control put on ASPX page does not appear in code behind, but if I create it with protected keyword and name being exactly the same as id it works fine. I can access such a web control from code behind and see the value assigned in IE. The problem is that the same routine does work for my A web control in B. When I assign the value IE, I keep getting null reference. ...how to call controls of web control form in coding of other forms?

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?
...How do I control one control from another control?
I have a page page1.aspx which is within a master page.
On page I have a table with two cells. Within each cell I have placed two controls (ascx) that I have developed.
Now I'd like to be able to get these two controls to interact. One needs to update the other. One has some search criteria that the other one needs to update its gridview. One needs to make the other visible/not visible at certain times. Out of the box neither control can see each other at all.
Is there a good article or someplace I can find some information on how to do this?
