Its very simple. On row data event You can add tooltip to a Cell.


Step1: Create a new Application:

Add a page name: gridTooltip

Step2: Add the following code inside the gridTooltip.aspx page:
ASP
<asp:gridview id="GridView1" runat="server" onrowdatabound="GridView1_RowDataBound" xmlns:asp="#unknown">
        </asp:gridview>


Step3: Inside gridTooltip.aspx.cs page add the following code:
C#
protected void Page_Load(object sender, EventArgs e)
   {
       if (!IsPostBack)
       {
           BindGrid();
       }
   }
   public class Data
   {
       public string Name
       {
           get;
           set;
       }
       public int Age
       {
           get;
           set;
       }
   }

   public void BindGrid()
   {
       Data obj = new Data();
       obj.Name = "Kabir";
       obj.Age = 28;

       Data obj1 = new Data();
       obj1.Name = "Safiul";
       obj1.Age = 28;

       List<Data> olist = new List<Data>();
       olist.Add(obj);
       olist.Add(obj1);

       GridView1.DataSource = olist;
       GridView1.DataBind();
   }

   protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
   {
       if (e.Row.RowType == DataControlRowType.DataRow)
       {
           e.Row.Cells[0].ToolTip = "My Name is: " + e.Row.Cells[0].Text;
           e.Row.Cells[1].ToolTip = "My age is: " + e.Row.Cells[1].Text;
       }
   }



---- Now run the application.
--- Hope it will help you
