This article describes how to apply hover effects on GridView rows using CSS.

Introduction

Last week, I learned a technique of applying a hover effect to an HTML table’s rows with the help of pure CSS, without using a single line of JavaScript code. Great! Isn’t it? Before that, I’ve been doing this using JavaScript, as in my previous article: Hotmail-like Mouse Over and Mouse Out Effects on GridView. I thought it might be interesting to implement this technique on a GridView in order to create a hover effect on the GridView rows. So, I’ve quickly created a sample application and decided to share it. Below is the implementation details of this technique for applying hover effect to GridView rows using CSS.

The GridView HTML Code

The HTML code for the GridView in this article will looks like:

<asp:GridView ID="gvHover" BackColor="WhiteSmoke" runat="server" AutoGenerateColumns="False"
              GridLines="Vertical" CssClass="grid-view" OnRowCreated="gvHover_RowCreated">
   <Columns>
      <asp:BoundField HeaderText="n" DataField="n">
         <HeaderStyle Width="25px" />
         <ItemStyle Width="25px" />
      </asp:BoundField>
      <asp:BoundField HeaderText="sqrt(n)" DataField="sqrtn">
         <HeaderStyle Width="150px" />
         <ItemStyle Width="150px" />
      </asp:BoundField>
      <asp:BoundField HeaderText="qbrt(n)" DataField="qbrtn">
         <HeaderStyle Width="150px" />
         <ItemStyle Width="150px" />
      </asp:BoundField>
   </Columns>
</asp:GridView>

Styling the GridView

In order to style the Gridview, attach a CSS class to it, like so:

<asp:GridView ... CssClass="grid-view" ... > ... </asp:GridView>

Styling the GridView’s Header Row, Normal Row, and Alternate Row

In order to style the GridWiew’s header, normal, and alternate rows, attach the CSS classes to these rows through the RowCreated event of the GridView, as:

//Add CSS class on header row.
if (e.Row.RowType == DataControlRowType.Header)
   e.Row.CssClass = "header";

//Add CSS class on normal row.
if (e.Row.RowType == DataControlRowType.DataRow && 
          e.Row.RowState == DataControlRowState.Normal)
   e.Row.CssClass = "normal";

//Add CSS class on alternate row.
if (e.Row.RowType == DataControlRowType.DataRow && 
          e.Row.RowState == DataControlRowState.Alternate)
   e.Row.CssClass = "alternate";

The CSS Classes

Below are the CSS classes that have been used above to style the GridView and its header, normal, and alternate rows:

.grid-view
{
   padding: 0;
   margin: 0;
   border: 1px solid #333;
   font-family: "Verdana, Arial, Helvetica, sans-serif, Trebuchet MS";
   font-size: 0.9em;
}

.grid-view tr.header
{
   color: white;
   background-color: #FF5600;
   height: 25px;
   vertical-align: middle;
   text-align: center;
   font-weight: bold;
}

.grid-view tr.normal
{
   color: black;
   background-color: #FDC64E;
   height: 25px;
   vertical-align: middle;
   text-align: center;
}

.grid-view tr.alternate
{
   color: black;
   background-color: #D59200;
   height: 25px;
   vertical-align: middle;
   text-align: center;
}

Adding a Hover Effect to the GridView rows

Finally, to apply the hover effect to the GridView rows, the following CSS is used:

.grid-view tr.normal:hover, .grid-view tr.alternate:hover
{
   background-color: white;
   color: black;
   font-weight: bold;
}

Note that the hover effect has been applied to the normal and alternate rows only, not on the header row. You can also use different color schemes for the normal and alternate rows separately, for the hover effect.

Using the CSS Classes

Put all the corresponding CSS classes in a stylesheet and give its reference on the web page’s head section, as:

<link href="StyleSheet.css" rel="stylesheet" type="text/css" />

Conclusion

That’s all about this technique. Just download the sample application and happy CSS! I have tested this application on various browsers and it worked fine. Below is the list of those browsers:
