Removing and adding a MultiPage for a tab

[Felix]

Hey!

I want to remove the PageView of a tab and give the tab a new PageView. Currently I'm doing it like this:

// Delete PageView from tab
RadTab tabToReset = TabStripBookings.FindTab(t => Convert.ToInt32(t.Attributes["bookingId"]) == bookingId);

if (tabToReset == null)
{
    System.Diagnostics.Debug.WriteLine($"Tab with booking id {bookingId} not found.");
    return;
}

// Remove old PageView
MultiPageBookings.PageViews.Remove(tabToReset.PageView);

// Add new PageView to tab
AddPageView(tabToReset);

 

The "AddPageView" Method looks like this:

RadPageView pageView = new RadPageView();
pageView.ID = "PageView_" + tab.Attributes["bookingId"] ;      // set the id of the pageview depending on the booking ID (0 for new booking)
pageView.CssClass = "contentWrapper" + tab.Index;
pageView.Attributes.Add("bookingId", tab.Attributes["bookingId"]);
pageView.Attributes.Add("day", tab.Attributes["day"]);
tab.PageViewID = pageView.ID;
MultiPageBookings.PageViews.Add(pageView);

 

And finally my PageViewCreated Event:

BookingControl userControl = (BookingControl) Page.LoadControl("BookingControl.ascx");

// PageView ID is: PageView_BookingId -> split in PageView & BookingId
// Set UserControl id to UserControl_BookingId
userControl.ID = "UserControl_" + e.PageView.ID.ToString().Split('_')[1];
userControl.BookingDeleted += UserControl_BookingDeleted;       // Subscribe to event when a booking is deleted
userControl.FormReset += UserControl_FormReset;                 // Subscribe to event when the form shall be reseted

if (e.PageView.HasAttributes)
{
    userControl.ValuesSet = true;
    userControl.BookingId = Convert.ToInt32(e.PageView.Attributes["bookingId"]);
    userControl.SelectedDay = DateTime.ParseExact(e.PageView.Attributes["day"], "dd.MM.yyyy", null);
}

e.PageView.Controls.Add(userControl);

 

How it shall work:

The first method is called via an event. The MultiPage should be removed and a new one (basically the same one as before, but freshly initialized from the database) is added to the MultiPage.

What it actually does:

At first I don't see the new Tab where it should be. Instead the content of the next tab is shown, but when I switch to another tab and then switch back, the correct PageView is shown.

 

Is there any solution for this problem? Am I missing something? Can I maybe tell the TabStrip to reload its PageView?

Hello Felix,

Would you please check if selecting the newly created PageView after adding it to the MultiPage solves the issue? The selection could be achieved by setting the Selected property of the PageView to true.
