This is very common problem in Web development that we need to freeze the GridView header at the time of scrolling, Here is one simple tips:
Step 1 : Create a CSS class as following
  1. .HeaderFreez  
  2. {  
  3. position:relative ;   
  4. top:expression(this.offsetParent.scrollTop);  
  5. z-index10;  
  6. }   

Step 2 Set Gridview’s HeaderStyle CssClass as follows
CssClass="HeaderFreez"
That’s all. Some times we need also maintain the scroll positions while selecting any data from GridView, and quite difficult to maintain the position while we are using AJAX, I have written a complete article on that, hope this will help Maintain GridView Scroll Position inside updatepanel

hi abhijit,

Thanks for the asking question becuase i got to know that expression is some thing where you can write your javascript code and save effort of writing long javascript.

top: expression(document.getElementById("AdjResultsDiv").scrollTop-2);
left: expression(parentNode.parentNode.parentNode.parentNode.scrollLeft);

Above line of code Gives the Top and Left coordinates of the TH tag which will be generated for the Header inside the Grid. We are using the expression tag to dynamically assign the values through JavaScript.

and For more deatil dom is

parentNode.parentNode.parentNode.parentNode.scrollLeft
=
parentNode- divgridpanel
parentNode- div
parentNode- table
parentNode- tr
