enter image description here

(this question buttons working scrollview)

have ideas how create control this?

it's vertical representation, idea understood: hide scrollbars , manipulate them manually. more responsive ui you'll need subscribe mousedown event instead of click, nullreference exceptions possible on every line of grid_click().

xaml:

        <listview.template>             <controltemplate>                 <grid buttonbase.click="grid_click">                     <grid.rowdefinitions>                         <rowdefinition height="16"/>                         <rowdefinition height="*"/>                         <rowdefinition height="16"/>                     </grid.rowdefinitions>                     <button content="^" grid.row="0"/>                     <button content="v" grid.row="2"/>                     <scrollviewer grid.row="1" verticalscrollbarvisibility="hidden">                         <itemspresenter/>                     </scrollviewer>                 </grid>             </controltemplate>         </listview.template>

code:

    private void grid_click(object sender, routedeventargs e) {         bool down = (e.originalsource button).content string == "v";         var scroller = visualtreehelper.getchild((e.originalsource button).parent, 2) scrollviewer;         scroller.scrolltoverticaloffset(scroller.verticaloffset + (down ? 1 : -1));     }

magical number 2 in getchild() index of scrollviewer inside parent (grid).
