Hi All,
I am getting an Unhandled Exception when I try to move / close a popup [I am not sure whether the exception occurs in popup, since it is an application unhandled exception].
The scenario is as follows,
I have a popup which has a Textbox in it
<
Popup x:Name="popComments">
<Canvas x:Name="canCommentsPop" Height="80" Width="220" Canvas.ZIndex="4">
<Border BorderBrush="Black" BorderThickness="2" CornerRadius="4">
<TextBox x:Name="txtNotesView" ScrollViewer.VerticalScrollBarVisibility="Auto" Width="220" Height="80" IsReadOnly="True" BorderThickness="0" MouseLeave="txtNotesView_MouseLeave"/>
</Border>
</Canvas>
</Popup>
The Code behind for Mouse Leave is as follows
private void txtNotesView_MouseLeave(object sender, MouseEventArgs e)
{
try
{
if (dtN != null)
{
dtN.Stop();
dtN = null;
}
dtN = new System.Windows.Threading.DispatcherTimer();
dtN.Interval =
new TimeSpan(0, 0, 0, 1, 0); dtN.Tick += new EventHandler(dtN_Tick);
dtN.Start();
}
catch
{
}
}
---------------------------------------------------------------------------------
void dtN_Tick(object sender, EventArgs e)
{
try
{
if (popComments.IsOpen)
Dispatcher.BeginInvoke(
delegate() { popComments.IsOpen = false; });if (dtN != null)
{
dtN.Stop();
dtN = null;
}
}
catch
{
}
}
The popup is opened when a Listbox Item [in DataTemplate] is clicked (<Border Width="180" Cursor="hand" MouseLeftButtonDown="Border_MouseLeftButtonUp">) ;
The Poblem occurs when i move the mouse after activating the popup!
The Exception is as follows
e.ExceptionObject
{System.ArgumentException: Value does not fall within the expected range.

What could be the possible reason for this!
Please help me solving this.
