Restore selected tab in hierarchy child page view after data refresh

Hello,

I have 3 hierarchical levels in my grid. Here is the structure:

Master template

|___tab1: Details (html view)

|___tab2: Orders (standard grid)

|___tab2-1: Clients (standard grid)

|___tab3: Networks (standard grid)

I'am inspired by some posts in the forum to save and restore the expanded rows and selected rows. It works great.

I save the grid state before data refresh, and reset after data refresh. Here is the code.

Dim scrollpos As Integer = -1

Dim CurrentRow As Integer = -1

Dim expandedRows As New List(Of Boolean)()

Dim selectedRows As New List(Of Boolean)()

Private Sub SaveSeletectedAndExpanded()

scrollpos = myGridView.TableElement.VScrollBar.Value

If myGridView.CurrentRow IsNot Nothing Then

CurrentRow = myGridView.CurrentRow.Index

End If

If myGridView.Rows Is Nothing Then

Exit Sub

End If

expandedRows.Clear()

selectedRows.Clear()

For i = 0 To myGridView.Rows.Count - 1

expandedRows.Add(myGridView.Rows(i).IsExpanded)

' How can I remember which page tab is displayed currently?

selectedRows.Add(myGridView.Rows(i).IsSelected)

Next

End Sub

Private Sub RestoreSeletectedAndExpanded()

If scrollpos <> -1 Then

myGridView.TableElement.VScrollBar.Value = scrollpos

End If

If CurrentRow <> -1 Then

myGridView.CurrentRow = myGridView.Rows(CurrentRow)

End If

If expandedRows IsNot Nothing Then

For i = 0 To expandedRows.Count - 1

myGridView.Rows(i).IsExpanded = expandedRows(i)

Next

End If

If selectedRows IsNot Nothing Then

For i = 0 To selectedRows.Count - 1

myGridView.Rows(i).IsSelected = selectedRows(i)

Next

End If

End Sub

But I've found that the current selected tabbed view in the expanded row is reset to default after refresh.

How can I save the current selected tabbled view index for the expanded rows ?

Thank you by advanced.

Edit a Winword file with Protected Parts in the document

Hi,

I was testing the RichTextEditor First Look in Demos and notice that it doesn't allow us to edit any parts of the document when the same document have specific parts of text locked for edition/change.

If I open the same document in Winword I can add or change text in others parts of the document that are not locked, without Word asking me the password or remove the "restrict editing" settings.

Is there any work around to overcome this issue in RichTextEditor?

PS: I don't want leave here any external links, but if you search for "how to lock specific text in word" in google you will see examples how to lock specific parts or sections of a winword document.

Error 2019.1.117 Upgrade Wizard

Hi,

I tried an update to 2019.1.117 (from 2018.3.1016) with the Upgrade Wizard and after the "Upgrade Wizard Information" I'll get an "Telerik VSExtensions Error"

Here the StackTrace:

System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.
   bei Telerik.WinControls.VSX.Wizards.UpgradeProjectWizard.GetShouldEnableHDPI()
   bei Telerik.WinControls.VSX.Wizards.UpgradeProjectWizard.GetPropertyValue(String propertyName)

   bei Telerik.WizardEngine.Helpers.EventHelper.<>c__DisplayClass1_0.<RaiseEvent>b__0()
   bei Telerik.WizardEngine.Helpers.EventHelper.CatchExceptionAndSendReport(Action action)

Does anyone got an idea what's missing?
