Styling header text in asp.net gridview - asp.net

Question

Q1. I have a hyperlink field in a grid view as below :
<asp:HyperLinkField Text="Analyze" />
I want it to be underlined at all times and not only when I hover. How do I do this ?
Q2. I want the header texts of the gridView to be center alligned.
I tried: HeaderStyle-HorizontalAlign="Left" but it doesn't work.
I also tried making a css class with :
<style type="text/css">
.header-center{
text-align:center;}
</style>
but this also doesn't work.
I am basically trying to center the header text,nothing fancy,but it is not happening.

You have to replace your code in BodyContent with the below.
Note: you can add your own colors to the grid
<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
<style type="text/css">
#MainContent_GridView2 tbody tr th {
text-align: center;
background: #808080;
height: 40px;
}
#MainContent_GridView2 tbody tr {
height: 20px;
background-color: #CCC;
}
#MainContent_GridView2 tbody tr:hover {
background-color: #808080;
}
#MainContent_GridView2 tbody tr td {
text-align: center;
height: 30px;
}
.linkfield {
text-decoration: underline;
text-align: center;
}
</style>
<asp:GridView ID="GridView2"
runat="server"
AutoGenerateColumns="False"
AllowPaging="True"
AllowSorting="True"
PageSize="25"
Height="800px"
Width="1200px"
OnPageIndexChanging="GridView2_PageIndexChanging">
<Columns>
<asp:HyperLinkField DataNavigateUrlFields="runId" DataTextField="runId" HeaderText="RunID" DataNavigateUrlFormatString="RunAnalysis.aspx?runId={0}" ItemStyle-Width="10%">
<ItemStyle Width="10%" CssClass="linkfield"></ItemStyle>
</asp:HyperLinkField>
<asp:BoundField DataField="prodDate" HeaderText="Date" DataFormatString="{0:MM/dd/yy}" ItemStyle-Width="10%">
<ItemStyle Width="10%"></ItemStyle>
</asp:BoundField>
<asp:BoundField DataField="buildNumber" HeaderText="Build Number" ItemStyle-Width="10%">
<ItemStyle Width="10%"></ItemStyle>
</asp:BoundField>
<asp:HyperLinkField DataNavigateUrlFields="PercentAnalysed" DataTextField="PercentAnalysed" HeaderText="Percent Analysed" ItemStyle-Width="10%">
<ItemStyle Width="10%"></ItemStyle>
</asp:HyperLinkField>
</Columns>
<PagerSettings FirstPageText="First" LastPageText="Last" NextPageText="Next" PreviousPageText="Previous" />
</asp:GridView>
</asp:Content>
Hope this helps.
