Feb 18, 2011
I have a webusercontrol with a flash control. I want to assign the movieurl from codebehind when the webusercontrol is registered in a new page.
<uc1:PopVideo
ID="PopVideo1"
runat="server"
/>
inside this webusercontrol I have a flash movie player that I can assign the movieurl in codebehind on the webusercontrol. The problem is that I need to assign the value from the new page the control is registered under. How can I access the flash control from the new page and assign the value?
I have a webusercontrol with a asp.net flash player. I need to be able to find the control and assign the movieurl from codebehind in the new registered page. How can I find the control that is inside a webusercontrol and is registered in new form and assign the value?
