Apply this style sheet to your gridview

CSS

 .HeaderStyle
{
font-family:verdana;
font-size:x-small;
width:100%;
position:relative;
top:expression(this.offsetParent.scrollTop-1);
margin-left:0;
}

Hi,
Its working at my side. Do as follows:
1) Add following stylesheet in your page under <style> tag
.HeaderStyle
{
font-family:verdana;
font-size:x-small;
position:absolute;
margin-left:0;
}

2) Now, following is gridview declaration in .aspx page.
<asp:GridView ID="GridViewSRL" runat="server" AutoGenerateSelectButton="True" OnLoad="GridViewSRL_Load" AllowSorting ="true" OnSorting="GridViewSRL_Sorting" HeaderStyle-CssClass="HeaderStyle" AutoGenerateColumns="true" OnRowDataBound="GridViewSRL_RowDataBound">

3) Add rowdatabound event in .cs file
protected void gvDistricts_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.RowIndex == 0)
e.Row.Style.Add("height", "50px");
}
}
now check.
