RadMulti page not retaining content (Urgent))

[Francis Frank]

Hello Telerik Team,

Please am trying to do a search and open the result on a new tab and a new pageview but the search result clears up each time i navigate back to it and if i try another search on a giving opened tab, it show me error:

Multiple controls with the same ID 'ctl03' were found. FindControl requires that controls have unique IDs.

I have tried to enable view state but it did not help.

RadTab newTab1 = new RadTab();

newTab1.Text = Session["session_newtab"].ToString();

newTab1.Width = Unit.Pixel(150);
RadTabStrip1.Tabs.Add(newTab1);

  (RadTabStrip1.FindTabByText(Session["session_newtab"].ToString())).Selected = true;
RadPageView newwindow = new RadPageView();
newwindow.ID = newTab1.Text;
newwindow.ContentUrl = "search/search_judges.aspx?name=" + item;
newTab1.PageViewID = newwindow.ID;
newwindow.Width = Unit.Pixel(878);
newwindow.Height = Unit.Pixel(785);
newwindow.EnableViewState = true;

RadMultiPage2.PageViews.Add(newwindow);

Please this is urgent on my timeline

 Thanks

Hi,

Please refer to the following help article here  where it's discussed the common causes for such error.  The error message is also self explanatory, a control with the same ID as the one that you are dynamically adding already exists on the page. If you want to add tabs and pageviews dynamically,  please follow the approach from the following demo here.

Thanks for the reply

But the link you sent is working with Usercontrol not a webpage

Please i want to display content in .aspx not ascx

Still needing help urgently for my timeline

Thanks

Hi,

The important aspect of the demo which I've provide is the approach on how to add RadTabs and RadPageViews dynamically. The fact that you are loading the content of your pageview using its ConentUrl property should not make any difference. My suggestion is to open a support ticket and provided a runnable sample page so we could examine your exact implementation.

All the best,
