how to call a c# wewbmethod on mouseover of linkbutton in asp.net?

is it possible to call a c# webmethod on mouseover on Linkbutton ? what i want is to call a webmethod in which i am binding a repeater control with datatable. How? in aspx:

<asp:LinkButton Text='<%#Eval("SNA")%>' ID="lnkpro1" runat="server"
CssClass="linkbutton" servicemethod="GetRecords"
OnClick="btn_Click1" CommandArgument='<%# Eval("Sets") %>'></asp:LinkButton>
in aspx.cs:

[System.Web.Script.Services.ScriptMethod()]
[System.Web.Services.WebMethod]
public void GetRecords(object sender, EventArgs e)
{

}
I am not getting the point that is how is it possible to call a webmethod on linkbutton mouseover. I have used a webmethod in textbox autocomplete extender but it has a propperty of calling a webmethod but is it so in this case also? Thank you.
