In this example, we define a CSS class “gridview-header” and apply it to the HeaderStyle of the GridView. The position property is set to “fixed” to keep the header row fixed at the top of the page. The top property is set to 0 to position the header row at the top, and the height property is set to 50px to specify a fixed height for the header row. The background-color property can be customized to match the design of your application.

If you prefer a more dynamic solution, you can use JavaScript to freeze the title header. This approach involves attaching an listener to the scroll event of the window and updating the position of the header row accordingly. Here's an example:





    

In this example, we attach an event listener to the scroll event of the window using JavaScript. Inside the event listener, we retrieve the header row element using its ClientID and calculate the scrollTop value to determine the scroll position. If the scroll position is greater than the height of the header row, we set the position property to “fixed” and position the header row at the top of the page. Otherwise, we set the position property to “static” to restore the default behavior.
