.net - Add button control(s) to SplitContainer Splitter -

is there way display controls (like buttons) on adjustable splitter displays between 2 panels in .net splitcontainer?

example:

i don't think splitcontainer natively supports this, overriding control functionality seems omni-present in numerous applications seems bit me - feel i'm over-thinking or missing obvious.

here's example uses tablelayoutpanel simulate splitcontainer.

using system; using system.diagnostics; using system.drawing; using system.windows.forms;  class form1 : form {     [stathread]     static void main()     {         application.enablevisualstyles();         application.setcompatibletextrenderingdefault(false);         application.run(new form1());     }      tablelayoutpanel rootpanel;     float originalwidth;     int splitpointx;      public form1()     {         controls.add(rootpanel = new tablelayoutpanel         {             columncount = 3,             columnstyles =             {                 // notice use of absolute here control 'splitting'                 new columnstyle(sizetype.absolute, 120f),                 // size of button panel                 new columnstyle(sizetype.autosize),                 // remaining size                 new columnstyle(sizetype.percent, 100f),             },             dock = dockstyle.fill,             rowcount = 1,             rowstyles = { new rowstyle(sizetype.percent, 100f) },         });          panel buttonpanel;         rootpanel.controls.add(buttonpanel = new panel         {             anchor = anchorstyles.top | anchorstyles.bottom,             backcolor = systemcolors.controldark,             margin = new padding(0),             minimumsize = new size(80, 0),             size = new size(80, 0),             controls =             {                 // usevisualstylebackcolor = true because altered container's backcolor                 new button { text = ">>", location = new point(19, 112), size = new size(40, 23), usevisualstylebackcolor = true },                 new button { text = ">", location = new point(19, 83), size = new size(40, 23), usevisualstylebackcolor = true },                 new button { text = "<", location = new point(19, 54), size = new size(40, 23), usevisualstylebackcolor = true },                 new button { text = "<<", location = new point(19, 25), size = new size(40, 23), usevisualstylebackcolor = true },             },         }, 1, 0);          buttonpanel.mousedown += (s, e) =>             {                 if (e.button == mousebuttons.left)                 {                     // capture mouse mouse move messages go control                     (s control).capture = true;                      // record original column width                     originalwidth = rootpanel.columnstyles[0].width;                      // record first clicked point                     // convert screen coordinates because window moving target                     point windowpoint = (s control).pointtoscreen(e.location);                     splitpointx = windowpoint.x;                 }             };         buttonpanel.mousemove += (s, e) =>             {                 if ((s control).capture)                 {                     point windowpoint = (s control).pointtoscreen(e.location);                      // calculate distance of mouse splitpoint                     int offset = windowpoint.x - splitpointx;                      // apply originalwidth                     float newwidth = originalwidth + offset;                      // clamp it.                     // control in left pane's minimumsize.width more appropriate 0                     newwidth = math.max(0, newwidth);                      // update column width                     if (math.abs(newwidth - rootpanel.columnstyles[0].width) >= 1)                         rootpanel.columnstyles[0].width = newwidth;                 }             };         buttonpanel.mouseup += (s, e) =>             {                 if (e.button == mousebuttons.left)                 {                     // release mouse capture                     if ((s control).capture)                         (s control).capture = false;                 }             };     } }
