title: How to change the background color of the tooltip for a control available inside gridview on hover
body: <p>I have a <code>linkbutton</code> control inside <code>gridview itemtemplate</code>. </p>
  
  <p>i want to customize the default <code>tooltip</code> view of that <code>linkbutton</code> control. How can i achieve this ?
  Here is my Grid and already it is binded data from another function.</p>
  
  <pre><code>&lt;asp:GridView ID="GridReports" runat="server" 
                OnRowDataBound="GridReports_RowDataBound"
                DataKeyNames="SubmitID" ShowFooter="true" 
                AutoGenerateColumns="false"&gt;
  
   &lt;asp:TemplateField&gt;
        &lt;HeaderTemplate&gt;Department Lead&lt;/HeaderTemplate&gt;
        &lt;HeaderStyle CssClass="HeaderStyleWidth100" /&gt;
        &lt;ItemTemplate&gt;
            &lt;asp:HiddenField ID="LabelDepartmentLead" 
                 Value='&lt;%#DataBinder.Eval(Container.DataItem, "DepartmentLead")%&gt;'
                 runat="server" /&gt;
            &lt;asp:LinkButton ID="LinkButtonView" Text="View" 
                 Font-Underline="false" Font-Bold="true" ForeColor="Blue" 
                 runat="server"&gt;&lt;/asp:LinkButton&gt;
        &lt;/ItemTemplate&gt;
        &lt;ItemStyle HorizontalAlign="Center" CssClass="EditItemStyle" /&gt;
    &lt;/asp:TemplateField&gt;
  &lt;/asp:GridView&gt;
  </code></pre>
  
  <p>And here is my DataBound where i am assigning the tooltip for the LinkButton control (which is the default tooltip style).</p>
  
  <pre><code>protected void GridReports_RowDataBound(object sender, GridViewRowEventArgs e)
  {
      if (e.Row.DataItem != null)
      {
          HiddenField LabelDepartmentLead = 
                     (HiddenField)e.Row.FindControl("LabelDepartmentLead");
          LinkButton LinkButtonView = 
                     (LinkButton)e.Row.FindControl("LinkButtonView");
          if (LabelDepartmentLead.Value == string.Empty)
          {
              LabelDepartmentLead.Value = "No Department Leads";
          }
          LinkButtonView.ToolTip = LabelDepartmentLead.Value;
      }
  }
  </code></pre>
  
  <p>How can i identify the tooltip style and customize it. Please help!</p>
