Textblock on my Silverlight StackPanel

Textblock on my Silverlight StackPanel

That may be happening because the internal Stack Panel, and every other Stack Panel that is in use does not constraint its children to the "visible" space that is found in the Stack Panel. And for that reason, the scroll viewer  for the application feels like having unlimited space, and the text block too has an unlimited space. You will need to use the Grid itself to correct that and the following is the code that you will need for that:

<StackPanelName="panel">

    <Grid>

        <Grid.RowDefinitions>

            <RowDefinition/>

        </Grid.RowDefinitions>

        <Grid.ColumnDefinitions>

            <ColumnDefinition/>

            <ColumnDefinition/>

        </Grid.ColumnDefinitions>

        <TextBlock Text="Text:"/>

        <ScrollViewerGrid.Column="1"

                                    BorderThickness="0"

                                    Height="33"

                                    VerticalScrollBarVisibility="Auto"

                                    HorizontalScrollBarVisibility="Disabled">

            <TextBlockTextWrapping="Wrap"

                                    Text="YourText"/>

        </ScrollViewer>

    </Grid>

</StackPanel>
