How to change the color of button in ButtonEdit cell while clicking in WinForms GridControl or GridDataBoundGrid?

ButtonEditStyleProperties sparam; 
// Adding new ButtonEditCell model to grid.
this.gridDataBoundGrid1.Model.CellModels.Add("ButtonEdit", new ButtonEditCellModel(this.gridDataBoundGrid1.Model));
// Gets ProductName column style. 
GridStyleInfo styleparam = this.gridDataBoundGrid1.Binder.InternalColumns["ProductName"].StyleInfo;
// changing Celltype for ProductName column.
styleparam.CellType = "ButtonEdit";
//Geting ButtonEditStyleProperties for ProductName column style.
sparam = new ButtonEditStyleProperties(styleparam);
sparam.ButtonEditInfo.BackColor = Color.Orange;
sparam.ButtonEditInfo.Text = "Edit-Method";
sparam.ButtonEditInfo.TextColor = Color.White;
//Hooking CellMouseUp event.
this.gridDataBoundGrid1.CellMouseUp += new GridCellMouseEventHandler(gridDataBoundGrid1_CellMouseUp);    
//Hooking MouseDown event.
this.gridDataBoundGrid1.MouseDown += new MouseEventHandler(gridDataBoundGrid1_MouseDown);
void gridDataBoundGrid1_MouseDown(object sender, MouseEventArgs e)
{
    int rowindex, colindex = 0;
    this.gridDataBoundGrid1.ViewLayout.PointToClientRowCol(e.Location, out rowindex, out colindex,true);
    if (this.gridDataBoundGrid1[rowindex, colindex].CellType == "ButtonEdit")
    {
        // Used to change the color while clicking on it.
        sparam.ButtonEditInfo.BackColor = Color.Red;
    } 
}

{
    if (this.gridDataBoundGrid1[e.RowIndex, e.ColIndex].CellType == "ButtonEdit")
    {
