Adding WPF controls with VB

Question

I'm new here!

My problem is the following piece of XAML:

<ScrollViewer>
    <Label x:Name="MainText">
        <TextBlock x:Name="DefaultText">
            Application launched successfully!
        </TextBlock>
    </Label>
</ScrollViewer>
<TextBox x:Name="EntryText" KeyDown="EntryText_KeyDown" />

I want to add TextBlocks from EntryText_KeyDown inside MainText. Although it's able to access both MainText and DefaultText I don't know how I can add an element. Googling seems to provide the C# solution of MainText.Add which doesn't seem to be usable(?) in VB.

Any help would be much appreciated!

Label can have only one child, so if you want to have multiple textblocks use layout containers like panels, grid

<ScrollViewer>

    <StackPanel x:Name="MainText">
        <TextBlock x:Name="DefaultText">
            Application launched successfully!
        </TextBlock>
    </StackPanel >
</ScrollViewer>

Then in code behind you can do:

MainText.Children.Add(new TextBlock());

If you want to add just one textblock in label then you can do:

TextBlock textblock = new TextBlock();
textblock.Text = "My Text";
MainText.Content = textblock ;
