How to: Position the Child Elements of a Grid
This example shows how to use the get and set methods that are defined on Grid to position child elements.
Example
The following example defines a parent Grid element (grid1) that has three columns and three rows. A child Rectangle element (rect1) is added to the Grid in column position zero, row position zero. Button elements represent methods that can be called to reposition the Rectangle element within the Grid. When a user clicks a button, the related method is activated.
<StackPanel Grid.Column="0" Grid.Row="0" HorizontalAlignment="Left" Orientation="Vertical">
<Button Click="setCol0">Move Rectangle to Column 0</Button>
<Button Click="setCol1">Move Rectangle to Column 1</Button>
<Button Click="setCol2" Margin="0,0,0,10">Move Rectangle to Column 2</Button>
<Button Click="setRow0">Move Rectangle to Row 0</Button>
<Button Click="setRow1">Move Rectangle to Row 1</Button>
<Button Click="setRow2" Margin="0,0,0,10">Move Rectangle to Row 2</Button>
<Button Click="setColspan">Span All Columns</Button>
<Button Click="setRowspan">Span All Rows</Button>
<Button Click="clearAll">Clear All</Button>
</StackPanel>
</Grid>

<TextBlock FontSize="15" HorizontalAlignment="Right" VerticalAlignment="Bottom" Grid.Column="0" Grid.Row="1" Margin="5">Column 0, Row 1</TextBlock>
<TextBlock FontSize="15" HorizontalAlignment="Right" VerticalAlignment="Bottom" Grid.Column="1" Grid.Row="1" Margin="5">Column 1, Row 1</TextBlock>
<TextBlock FontSize="15" HorizontalAlignment="Right" VerticalAlignment="Bottom" Grid.Column="2" Grid.Row="1" Margin="5">Column 2, Row 1</TextBlock>
<TextBlock FontSize="15" HorizontalAlignment="Right" VerticalAlignment="Bottom" Grid.Column="0" Grid.Row="2" Margin="5">Column 0, Row 2</TextBlock>
<TextBlock FontSize="15" HorizontalAlignment="Right" VerticalAlignment="Bottom" Grid.Column="1" Grid.Row="2" Margin="5">Column 1, Row 2</TextBlock>
<TextBlock FontSize="15" HorizontalAlignment="Right" VerticalAlignment="Bottom" Grid.Column="2" Grid.Row="2" Margin="5">Column 2, Row 2</TextBlock>
</Grid>
The following code-behind example handles the methods that the button Click events raise. The example writes these method calls to TextBlock elements that use related get methods to output the new property values as strings.
Private Sub setCol0(ByVal sender As Object, ByVal e As RoutedEventArgs)
Grid.SetColumn(rect1, 0)
txt1.Text = "Rectangle is in Column " + Grid.GetColumn(rect1).ToString()
End Sub
Private Sub setCol1(ByVal sender As Object, ByVal e As RoutedEventArgs)
Grid.SetColumn(rect1, 1)
txt1.Text = "Rectangle is in Column " + Grid.GetColumn(rect1).ToString()
End Sub
Private Sub setCol2(ByVal sender As Object, ByVal e As RoutedEventArgs)
Grid.SetColumn(rect1, 2)
txt1.Text = "Rectangle is in Column " + Grid.GetColumn(rect1).ToString()
End Sub
