Checkbox check higlight gridview not working

I want a functionality where I want where, If I select one row, that particular row should get highlighted. I have written the javascript code, but it is not working properly

function Check_Click(objRef) {
      var row = objRef.parentNode.parentNode;
      if (objRef.checked) {
          row.style.backgroundColor = "#FFF6BD";
      }
      else {
          if (row.rowIndex % 2 == 0) {
              row.style.backgroundColor = "#FFF6BD";
          }
          else {
              row.style.backgroundColor = "white";
          }
      }
      var GridView = row.parentNode;
      var inputList = GridView.getElementsByTagName("input");
      for (var i = 0; i < inputList.length; i++) {
          var headerCheckBox = inputList[0];
          var checked = true;
          if (inputList[i].type == "checkbox" && inputList[i] != headerCheckBox) {
              if (!inputList[i].checked) {
                  checked = false;
                  break;
              }
          }
      }
      headerCheckBox.checked = checked;
  }

Also see the gridview code for ref:-

<asp:TemplateField HeaderText="Select" ItemStyle-Width="30">
    <ItemTemplate>
        <asp:CheckBox ID="chkDelete" runat="server" onClick="Check_Click(this)" />
    </ItemTemplate>
</asp:TemplateField>
