.NET bug. How to fix?

In my complex program TextBox.Text is interconnected with Grid.Width. When I clear TextBox, .NET is crashed.

The problem is that inside TextBox.TextChanged I set Grid.Width and inside Grid.SizeChanged I set TextBox.Text. Thus, TextBox.Text is set inside two nested event handlers.

Could anyone help to fix this bug without Timer or Binding?

The runtime has encountered a fatal error. The address of the error was at 0x6c05e4ad, on thread 0x2844. The error code is 0x80131623. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.

I created a test WPF app to check this bug separately.

XAML:

<Grid Height="350">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="350" />
        <ColumnDefinition Width="350" />
    </Grid.ColumnDefinitions>
    <Grid Grid.Column="0"
          x:Name="grid"
          Width="300"
          Height="300"
          HorizontalAlignment="Center"
          VerticalAlignment="Center"
          Background="Red"
          SizeChanged="grid_SizeChanged" />
    <TextBox Grid.Column="1"
          x:Name="text"
          Text="300"
          TextChanged="text_TextChanged" />
</Grid>

Code behind:

private void grid_SizeChanged(object sender, SizeChangedEventArgs e)
{
    text.Text = grid.Width.ToString();
}

private void text_TextChanged(object sender, TextChangedEventArgs e)
{
    if (text.Text == "")
        grid.Width = double.NaN;
}

I solved this problem by using the Dispatcher:

private void grid_SizeChanged(object sender, SizeChangedEventArgs e)
{
    //text.Text = grid.Width.ToString();
    Dispatcher.BeginInvoke(new Action(() => text.Text = grid.Width.ToString()));
}

Thank you all for "help" and negative rating.
