Try this..working fine.
string passstr = string.Empty;
passstr = "I Love My India";
tag_label.Attributes.Add("onmouseover", "tooltip.show('"+ passstr +"')");
What I tried, because
tooltip
is unassigned for me.
string passstr = string.Empty;
passstr = "I Love My India";
tag_label.Attributes.Add("onmouseover", "alert('"+ passstr +"')");
Thanks
