[Solved] ListView, UserControl, RadWindow

[Andrew Thompson]

I've created a userControl that has an imagebutton. Attached to that is a RadWindow via the OpenerElementID of the imagebutton. That popups a window with the required aspx page (in this case ImageSelector.aspx). When that form is closed it returns the path of the image selected. And then updates the image in the imagebutton.

All works great. Except when I had another usercontrol. Then when I click on the imagebutton of the second control does not fire.

When I check out the rendered HTML i see two identical usercontrl rendering including the same openerElementID and JavaScript callback function.

I think what I need is a method to supply the 'calling' control id to the imageselector.aspx so that it can return it in the arguments coming back.

(note I've used both ASP.NET ImageButton and HTML img element and have the same problem).

Thanks.

Hello Andrew,

You should use RadWindow's client-side API instead of OpenerElementID - OpenerElementID is intended to be used in simple scenarios only (more information on the subject is available in this demo's description). You can check the Opening Windows help article for more information on how to open RadWindow in different scenarios. The Using RadWindow as a Dialog help article will also help you get started.
