There are sometimes where we need to highlight data for user when he is interacting with the Web application.In this article we will be using A Grid view and highlight its rows when the user moves its pointer to different rows.

Pre-Requisite for Article

  2. Basic knowledge of CSS.


  1. Highlight GridView Rows using JQuery on Mouse Over

Using the code

  1. Create a New Website in VS 2010 -> Add a Web Form.
  2. Create 2 New Folder by right clicking in the website name and name both the folder as Jquery and CSS respectively.
  3. Now follow the steps for adding Jquery File from the article link pasted above.
  4. Now Right Click on the Folder named CSS and Select Add New Item -> StyleSheet.css ->  Name it as Main.css. The Solution Explorer should be like (screen 1)

Let us start Implementation

// CSS File for Color Change background of Gridview Rows on Mouse Over
        font-family::Bookman Old Style;
        font-size: 15pt;
        cursor: pointer;

Explanation of CSS

  1. The Body class is by default added and we have set the Font as Bookman Old Style and size to 15
  2. Now since we want to change the gridview color we will use the td element of table and set the cursor property to pointer.
  3. We then create a Class named Hover_row and change the color to Lime.

// JQuery function to change the Color of GridView rows
<script type="text/javascript">
       $(document).ready(function () {
           $('#xdata tr:has(td)').mouseover(function () {
           $('#xdata tr').mouseout(function () {
Explanation of Jquery Function

  1. We first load the document.ready function and then we go ahead and declare a function and get the id of gridview using the # Tag and then find the td tag of table and append mouse over function and once we append to mouse over function we add the cssclass that we have wrote in CSS file.
  2. To bring back the Color to normal we find the TR element and assign the Mouse out function and use the remove class method to bring back the color to normal.

        <br />
        <div align="center">
        <asp:GridView ID="xdata" runat="server">
