How to access individual controls from a form containing the web user control containing those controls
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 All, I have a control I've created, which can have a number of child controls - also user controls - stored as an ArrayList, which can be added wither a design time or programmatically.My problem is when I add to the list programmatically, it doesn't persist them. So if I add 3 child controls in step 1 of a wizard, with the aim that those three will be visible inside the parent in step 3, what happens is that the parent has no child controls and the item count is 0.Can anyone help?

Hi, I have 2 User controls on a page and want Control1 to call a method of Control2. Is this Possible?

When I click on the button on the DataList in Con1 it adds the item into the Session based Cart. However it does not update the Cart Preview. I need to call BindPreview() in Con2 in order to update the Cart Preview...

I have a usercontrol on my page which displays a running marquee text. It makes use of an UpdatePanel (within the user control) to refresh the marquee text (within the updatepanel) at periodic intervals. For this I added a timer control and its tick event as an async postback trigger for the UpdatePanel.
I have a lot of textboxes and dropdown list boxes (all with runat=server) on the page outside the above user control. These are also contained in different UpdatePanels.
Problem is, when the user control does a postback to refresh the marquee text, it causes some of...User Control Within UserControl

User Control A has a panel defined (cpeNewUser) that I want to manipulate from the code behind of User Control B based on some event that happens.So putting this in my code behind of User Control B won't work as it has no idea of cpeNewUser:cpeNewUser.Collapsed = true;So is it because only at runtime they are married up and because of this you cannot access each other's objects at compile time?
