R – Silverlight Button Click Event

silverlightsilverlight-2.0vb.net

I have a silverlight page with a textblock and button on it. Like this:

<TextBlock x:Name="txbNote" Margin="50,50" Text="Hello"/>        
<Button x:Name="btnCheck" Height="40"  Click="btnCheck_Click" ClickMode="Press" Margin="50,50,50,50" Content="Check Service"/>

Here is the handler for the click event:

Private Sub btnCheck_Click(ByVal sender As Object, ByVal e As EventArgs) 'Handles btnCheck.Click
  txbNote.Text = "I Was Clicked"
End Sub

It works… but…
Why doesn't this work?

<Button x:Name="btnCheck" Height="40"  Click="btnCheck_Click" ClickMode="Press" Margin="50,50,50,50" Content="Check Service"/>
<TextBlock x:Name="txbNote" Margin="50,50" Text="Hello"/>

The only change is the relative position of the textblock and button. The button's click event (and every other event I tried) just doesn't fire unless the textblock is before the button in the xaml.

You may need to post more code as this could be an issue with the surrounding tags, such as the container that these controls are in.

If you're unable to paste it all to StackOverflow, use www.dpaste.com or www.pastebin.com.

.net – How to automatically select all text on focus in WPF TextBox

We have it so the first click selects all, and another click goes to cursor (our application is designed for use on tablets with pens).

You might find it useful.

public class ClickSelectTextBox : TextBox
{
    public ClickSelectTextBox()
    {
        AddHandler(PreviewMouseLeftButtonDownEvent, 
          new MouseButtonEventHandler(SelectivelyIgnoreMouseButton), true);
        AddHandler(GotKeyboardFocusEvent, 
          new RoutedEventHandler(SelectAllText), true);
        AddHandler(MouseDoubleClickEvent, 
          new RoutedEventHandler(SelectAllText), true);
    }

    private static void SelectivelyIgnoreMouseButton(object sender, 
                                                     MouseButtonEventArgs e)
    {
        // Find the TextBox
        DependencyObject parent = e.OriginalSource as UIElement;
        while (parent != null && !(parent is TextBox))
            parent = VisualTreeHelper.GetParent(parent);

        if (parent != null)
        {
            var textBox = (TextBox)parent;
            if (!textBox.IsKeyboardFocusWithin)
            {
                // If the text box is not yet focussed, give it the focus and
                // stop further processing of this click event.
                textBox.Focus();
                e.Handled = true;
            }
        }
    }

    private static void SelectAllText(object sender, RoutedEventArgs e)
    {
        var textBox = e.OriginalSource as TextBox;
        if (textBox != null)
            textBox.SelectAll();
    }
}

R – Silverlight button style

The binding would look like this:

<TextBlock Text="{TemplateBinding Content}"/>

The problem is when I try to set the content to something other than text:

    <Button>
        <Button.Content>
            <Rectangle Fill="#FFB51111"/>
        </Button.Content>
    </Button>

In this case using the ContentPresenter would work better. It uses the same binding expression, but can display more than text. But all that is really up to you.
