GridSplitter

GridSplitter lets you offer the user a way to adjust the layout of your application, by changing the size of a column or row in a grid. This lets you provide a similar feature to Windows Explorer, where if you turn on the folder view, or one of the other panels that can appear on the lefthand side of a window, you can change the amount of space available to the panel by dragging on the vertical bar between the panel and the main area. You can use GridSplitter only to rearrange a Grid panel (see Example 5-28).

Example 5-28. GridSplitter

<Grid Height="100" Width="400">
  <Grid.ColumnDefinitions>
    <ColumnDefinition Width="1*" />
    <ColumnDefinition Width="6" />
    <ColumnDefinition Width="2*" />
  </Grid.ColumnDefinitions>

  <Ellipse Grid.Column="0" Fill="Red" />
  <GridSplitter Grid.Column="1" HorizontalAlignment="Stretch" />
  <Ellipse Grid.Column="2" Fill="Blue" />
</Grid>

This puts a GridSplitter into the middle of the three columns. As Figure 5-29 shows, if the user moves the mouse over the GridSplitter, the mouse pointer changes to the horizontal resize arrow. Dragging the slider resizes the columns on either side.
