Hello,

If you go to the Smart Tag for the control, then you can set which buttons you would like to see in the RadPageView using the StripButtons property. There is a screenshot in this help topic

hope that helps

Is there a way to disable/remove the close icon/button on the page view programatically?

Hello David,

Thank you for your question.

In order to hide the close buttons, you should consider setting the following properties:

(radPageView1.ViewElement as RadPageViewStripElement).ShowItemCloseButton = false;
(radPageView1.ViewElement as RadPageViewStripElement).StripButtons = StripViewButtons.Scroll;

I hope this helps. If you have any further questions, feel free to ask.

All the best,

Is it possible to display the close button on selected tabs only?  I want to allow users to close some tabs, but not others.  Thanks.

Hello Brendan,

You can do that by using the following code in the SelectedPageChanging event:

void radPageView1_SelectedPageChanging(object sender, RadPageViewCancelEventArgs e)
{
    radPageView1.SelectedPage.Item.ButtonsPanel.CloseButton.Visibility = ElementVisibility.Collapsed;
    e.Page.Item.ButtonsPanel.CloseButton.Visibility = ElementVisibility.Visible;
}

I hope this helps.

Thank you Stefan, it works fine.  I'm trying to figure out how to have the close button appear when I hover over a page, the same as VS 2012 does.  How would I achieve that - in the MouseEnter or MouseHover event?

Here is the code I used for when a tab is changed, I would still need this.  I wasn't sure how to identify the page I never want closed, so I used the name (pgmain).  I also had to add the On Error part as I was getting an error when starting the project. "An error occurred creating the form. See Exception.InnerException for details.  The error is: Object reference not set to an instance of an object."

Private Sub pageViewDocs_SelectedPageChanging(sender As Object, e As RadPageViewCancelEventArgs) Handles pageViewDocs.SelectedPageChanging
     On Error Resume Next
    pageViewDocs.SelectedPage.Item.ButtonsPanel.CloseButton.Visibility = ElementVisibility.Collapsed
    If e.Page.Name.ToLower <> "pgmain" Then
        e.Page.Item.ButtonsPanel.CloseButton.Visibility = ElementVisibility.Visible
    End If
End Sub

Hello Brendan,

Thank you for writing back.

To show the close button, only when the item is hovered, you can use the MouseMove event of the control:

Private previouslyHoveredItem As RadPageViewStripItem
Private Sub radPageView1_MouseMove(sender As Object, e As MouseEventArgs)
    If previouslyHoveredItem IsNot Nothing Then
        previouslyHoveredItem.ButtonsPanel.CloseButton.Visibility = ElementVisibility.Collapsed
    End If

    Dim hoveredItem As RadPageViewStripItem = TryCast(radPageView1.ElementTree.GetElementAtPoint(e.Location), RadPageViewStripItem)
    If hoveredItem IsNot Nothing Then
        hoveredItem.ButtonsPanel.CloseButton.Visibility = ElementVisibility.Visible
        previouslyHoveredItem = hoveredItem
    End If
End Sub

As to the exception that you are getting, it is caused by the fact that the first time the event is fired, the control still does not have its SelectedPage set, so it is null and throws an exception when you try to access it. You can overcome this with a simple check:

Private Sub RadPageView1_SelectedPageChanging(sender As System.Object, e As Telerik.WinControls.UI.RadPageViewCancelEventArgs) Handles RadPageView1.SelectedPageChanging
      If RadPageView1.SelectedPage IsNot Nothing Then
          RadPageView1.SelectedPage.Item.ButtonsPanel.CloseButton.Visibility = ElementVisibility.Collapsed
      End If
      If e.Page.Name.ToLower <> "pagepageviewpage2" Then
          e.Page.Item.ButtonsPanel.CloseButton.Visibility = ElementVisibility.Visible
      End If
  End Sub

I hope that you find my answer useful.

Thank you for the help Stefan!

In Desing Mode:

You can select ViewElement Option and then Search Strip Buttons Option and set it to None.

RadPageView >> ViewElement >> Strip Buttons >> None

You can see the image attached.

Hi!

I would like to show everything except the close button.
I would like to show both the scroll and the item list, but not the close button.

Is that possible?
The answers in this thread does not seem to solve this problem.

Hi Odne,

Thank you for writing.

To show everything but the close button you can use this code:

((RadPageViewStripElement)radPageView1.ViewElement).StripButtons |= ~StripViewButtons.Close;

To have just Scroll and ItemList:

((RadPageViewStripElement)radPageView1.ViewElement).StripButtons = StripViewButtons.Scroll | StripViewButtons.ItemList;

I hope this helps.
