HI

I have the same problem as Keltyx. I tried it with the solution from Mike but it didn't work. Is there a other solution for this problem.

GetPopupGalleryTool(KEY_PG_DATAINPUT_TEMPLATESELECTION).SelectedItemKey = m_oRibbonMenuViewModel.Template

If Not GetPopupGalleryTool(KEY_PG_DATAINPUT_TEMPLATESELECTION).UIElement Is Nothing Then
      GetPopupGalleryTool(KEY_PG_DATAINPUT_TEMPLATESELECTION).SelectedItem.BringIntoView(GetPopupGalleryTool(KEY_PG_DATAINPUT_TEMPLATESELECTION).SharedProps.ToolInstances(0), Nothing, GalleryArea.Preview)

End If

Private Function GetPopupGalleryTool(ByVal i_strKey As String) As PopupGalleryTool

    Return CType(tbChannelPreCalc.Tools(i_strKey), PopupGalleryTool)

End Function

It might be in the UltraToolbarsManager.MergedTools collection if it only exists on the child. Did you try there?

Hello Mike

your soulution works fine but sometimes i get a InvalidOperationException "The item to bring into view does not exist in the gallery preview.". Is it possible to check if a Item exists in the gallery preview ?

The PopupGalleryTool.Items collection has a Contains method which you could call to see if the item is present in the gallery.

I tried i with the contians Function of the gallery i get true back but i also get the InvalidOperationException.

Can you post a sample which reproduces the problem?

Hi,

Today I have installed the newest version an this issue still exists. Do you have any plans to fix it ? I think it should be possible to fix at a time span of 5 years.

regards,

Christian

This issue has been submitted to our development team for review and you will receive more information regarding the issue from the support case that has been opened for you.

Ok, after looking into this some more, it looks like an item can be hidden from the preview area if your gallery uses groups and the item doesn't belong to any group. It can also be hidden if the gallery contains filters and a filter is selected which doesn't include the item. Unfortunately, it doesn't look like there's an easy way to determine the visible items in the preview area. This can be considered a bug. I have forwarded this post to the Developer Support Manager and a DS engineer will be contacting you about this issue.

Hello Mike,

I have a a function in my Project wich is called WritePropertiestoScreen. This Function is called if i change somthing in my UI. In this this function i clear all the items from the PopUpGallery after that i fill it new.  After that i check if a Item with the key xy existis in the Gallery.

 If GetPopupGalleryTool(KEY_PG_CALCULATION_FIXPOINT).Items.Count > 0And Not IsNothing(m_oRibbonMenuViewModel.Fixpoint) Then
      GetPopupGalleryTool(KEY_PG_CALCULATION_FIXPOINT).SelectedItem = (From i As GalleryToolItem In GetPopupGalleryTool(KEY_PG_CALCULATION_FIXPOINT).Items _
                                                                       Where i.Key = m_oRibbonMenuViewModel.Fixpoint).FirstOrDefault()
      m_bDoAgain = Not BringIntoViewSelectedPopUpGalleryItem(KEY_PG_CALCULATION_FIXPOINT)
    End If

Private Function BringIntoViewSelectedPopUpGalleryItem(ByVal i_strPopUpGalleryKey As String) As Boolean
    Dim bRet As Boolean = True
    If Not tbFixpoint.MdiParentManager Is Nothing Then
      Dim rootTool As PopupGalleryTool = CType(tbFixpoint.MdiParentManager.MergedTools.Item(i_strPopUpGalleryKey), PopupGalleryTool)
      For Each instanceTool As ToolBase In rootTool.SharedProps.ToolInstances
        If Not instanceTool.UIElement Is Nothing And TypeOf instanceTool Is PopupGalleryTool Then
          Try
            If GetPopupGalleryTool(i_strPopUpGalleryKey).Owner.Visible And CType(instanceTool, PopupGalleryTool).Items.Contains(rootTool.SelectedItem) Then
              rootTool.SelectedItem.BringIntoView(instanceTool, Nothing, GalleryArea.Preview)
            Else
              bRet = False
            End If
          Catch ex As Exception
            bRet = False
          End Try
        Else
          bRet = False
        End If
      Next
    End If
    Return bRet
  End Function

The m_bDoAgain is for the timer. I have a timer and if m_bDoAgain is true i call the function BringIntoView again.
