How to change multiple GridViews Row Color on Mouseover using jQuery and CSS in ASP.Net

Hi robertrack,

Provide a common class for all the GridView and use class selector to apply for all the GridView like below.

<asp:GridView ID="GridView1" CssClass="highlight" runat="server" AutoGenerateColumns="false">
    <Columns>
    </Columns>
</asp:GridView>

<asp:GridView ID="GridView2" CssClass="highlight" runat="server" AutoGenerateColumns="false">
    <Columns>
    </Columns>
</asp:GridView>

<asp:GridView ID="GridView3" CssClass="highlight" runat="server" AutoGenerateColumns="false">
    <Columns>
    </Columns>
</asp:GridView>

 Use the below code to apply hover effect for all the gridview.

$(".highlight td").hover(function () { });
