asp.net - How to do a count on table's <tr> and make some andother background-color in vb.net -


in asp.net i'm having in frontend, , in backend(vb) want count on <tr>'s on page , every other (so 2nd, 4th, 6th,...) has have background color.

how count <tr>'s on page , how can tell them give every other 1 background-color?

this frontend:

<p class="title"><asp:label id="label1" runat="server" text="title 1"></asp:label></p>      <table class="table">         <tr><td>person 1</td><td>bestuurder</td></tr>          <tr><td>person 2</td><td>zaakvoerder</td></tr>     </table>      <p class="title"><asp:label id="label3" runat="server" text="title 2"></asp:label></p>     <asp:button id="btn_add_beheerder" runat="server" text="beheerder toevoegen" class="btn_add"/>      <table class="table">         <tr><td>person 3</td><td>beheerder</td></tr>         <tr><td>person 4</td><td>beheerder</td></tr>     </table>

the backend going on page_load. think best way putting every <tr> in array , every array[i] that's dividable 2 give background-color? best way work?

you of course in gazillion different ways. here 1 suggestion.

<asp:gridview id="gv" runat="server" datasourceid="ds">             <columns>                 <asp:boundfield datafield="person" />                 <asp:boundfield datafield="something else"/>             </columns>             <alternatingrowstyle backcolor="blue" />         </asp:gridview>         <asp:sqldatasource runat="server" id="ds"             connectionstring="your connectionstring"             selectcommand="--select stuff">         </asp:sqldatasource>
