Hi Jpark,

This is a known issue and has been fixed on Silverlight 3 RTW. I have tested it on a internal siverlight 3 version.

Best regards,

Jonathan,

Here's your repro....

<UserControl

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

x:Class="TestSilverlight.Page"

Width="640" Height="480">

</Grid>

</UserControl>

***Code Behind***

using System;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Documents;

using System.Windows.Ink;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Animation;

using System.Windows.Shapes;

using System.Windows.Browser;

namespace TestSilverlight

{

public partial class Page : UserControl

{

public Page()

{

// Required to initialize variables

InitializeComponent();

}

private void Button_Click(object sender, RoutedEventArgs e)

{

HtmlPage.Window.Alert("close me");

}

If you want you can replace the HtmlPage.Window.Alert to Messagebox.Show It doesn't happen as consistently, but it does happen if you continue to press the enter button.

Steps to reproduce:

launch app

click button

dismiss modal popup by pressing the enter key

press enter again

repeat pressing the enter key until exception is thrown.

Hi Satyajit,

I got your empty reply. Did your problem persist there? How about add your MessageBox to deleteFunction block.

public void deleteFunction(object obj)
{

MessageBox.Show(strMsg);
}

If it doesn't work, please share a tiny repro here.

Best regards,

Jonathan

hello Jonathan

The error is arise for

MessageBox.Show(strMsg);

When someone press enter more than two time when this messagebox show message

It show the exception .

We are handle the exception by focus on other controls for any keydown event.

thank you for your suggestion

Hi Satyajit,

I guess you call this on its KeyDown event. Please take a look at this thread. Please use the below code snippet and have a try.

Dispatcher.BeginInvoke(new AsyncDelete(deleteFunction), new object[]{ids});
public delegate void AsyncDelete(object obj);
public void deleteFunction(object obj)
{
HtmlPage.Window.Invoke("DeleteAnnotationsById", (string)obj);
}
If it doesn't work, please feel free to let me know with a tiny repro.

Best regards,

Jonathan
