Code:
public Window1()
{
InitializeComponent();
base.DataContext = new DataSource();
var items = new string[] { "A", "B", "C" };
this.tab.ItemsSource = items;
var collView = CollectionViewSource.GetDefaultView(items);
collView.CurrentChanging += this.OnTabItemSelecting;
}
void OnTabItemSelecting(object sender, CurrentChangingEventArgs e)
{
bool allow = this.chk.IsChecked.GetValueOrDefault();
if (!allow)
{
// SelectedContent hasn't changed yet, so use it to figure out
// the index of the previously selected tab
int prevIdx = this.tab.Items.IndexOf(this.tab.SelectedContent);
this.tab.SelectedIndex = prevIdx;
}
}Converted code via http://converter.telerik.com/;
Code:
Public Sub Window1()
InitializeComponent()
MyBase.DataContext = New DataSource()
Dim items = New String() {"A", "B", "C"}
Me.tab.ItemsSource = items
Dim collView = CollectionViewSource.GetDefaultView(items)
collView.CurrentChanging += AddressOf Me.OnTabItemSelecting
End Sub
Private Sub OnTabItemSelecting(ByVal sender As Object, ByVal e As CurrentChangingEventArgs)
Dim allow As Boolean = Me.chk.IsChecked.GetValueOrDefault()
If Not allow Then
Dim prevIdx As Integer = Me.tab.Items.IndexOf(Me.tab.SelectedContent)
Me.tab.SelectedIndex = prevIdx
End If
End SubSo, please somebody explain me how that vb.net code works in WPF.
