slider - WPF Zoom Control implement MiniMap -

i have implemented simple zoom control in project using slider control:

<grid grid.row="1" grid.column="0" margin="5,5,5,5">             <grid.rowdefinitions>                 <rowdefinition height="auto"/>                 <rowdefinition height="*"/>                 <rowdefinition height="auto"/>             </grid.rowdefinitions>             <button name="zoomincbutton" content="+" margin="2" grid.row="0" click="zoomincbutton_click"/>             <slider x:name="zoomctrl" orientation="vertical" grid.row="1"                 minimum="0.0" maximum="8.0" largechange="0.15" smallchange="0.01"  value="1.0"/>             <button name="zoomdecbutton" content="-" margin="2" grid.row="2" click="zoomdecbutton_click"/>         </grid>
