How to show Tooltip with latest updated row details on mouse hover of GridView column using jQuery in ASP.Net

Hi mangusiva,

You need to add "ontick" event in your code.I have given below example so please refer the below code and implement as per your requirement.

HTML

   <asp:Timer ID="Timer1" runat="server" Interval="3000" ontick="Timer1_Tick">
</asp:Timer>

C#

protected void Timer1_Tick(object sender, EventArgs e)
{
    GetData();
}

private void GetData()
{
    //Get your Data here... 
}

I hope works for you.
