i did see this demo, but its not what i wanted to do. this demo access the preview on the side and change its values. however i wanted to access the next tab dropdown and add data there from the previews tab selection.
here is a sample i used to load data in a dropdown in the second tab from the first tab selection
private void UpdatePreview()
var RadTabStrip = Page.FindControl("RadTabStrip1");
.DataSource = _part.GetPartsCatalog(Convert.ToInt32(package.Text), Convert.ToInt32(version.Text), "USD", 148, 53);
drop here is null.
is there is a way to access the contenct of radpageview.
