DockPanel in WPF
As the name says you can dock your controls in to either Top, Left, Right or Bottom of the panel. Placing a control to a location can be done using the Dock property with the values Left, Top, Right and Bottom.
ln1: <DockPanel>
ln2: <Button DockPanel.Dock="Top" Content="Button1" />
ln3: <Button DockPanel.Dock="Bottom" Content="Button2" />
ln4: <Button DockPanel.Dock="Left" Content="Button3" />
ln5: <Button DockPanel.Dock="Right" Content="Button4" />
ln6: <Button Content="Button5" />
ln7: </DockPanel>This will dock the button1 to the top of the container, button2 to the bottom and so on.
The order in which we dock the controls matters in here. If we move ln4 to ln3 and ln3 to ln4, the layout will look different.
If you dock a control to a location, the control will remain docked to that location irrespective to the size of the container. Take a look at the schreenshot shown below (with the container maximised).
Although this allows us to fix some controls to any edge of the container, we cannot position controls explicitly using this panel.
