Column Resizing in GridView

The ASP.NET GridView does not support column resiziing. You must use a third party server control like:

http://demos.telerik.com/aspnet-ajax/grid/examples/client/resizing/defaultcs.aspx
http://demos.devexpress.com/aspxgridviewdemos/Columns/ColumnResizing.aspx
http://ideasparks.codeplex.com/

I recommend using coolgrid control of irespaks.
CoolGridView is a web control that extends or enhances an ASP.NET GridView control to deliver the following features:

Display fix column headers, footer and pager
Supports scrollable content
User-resizeable column widths (New!)
Maintains scroll position and column widths after a postback or callback (New!)

You can also make a resizable GridView using jQuery colResizable-1.3.min.js.You can download it from http://quocity.com/colresizable/

Step 1: Your .aspx page like:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <link href="css/main.css" rel="stylesheet" type="text/css" />
    <script src="Scripts/jquery.js" type="text/javascript"></script>
    <script src="Scripts/colResizable-1.3.min.js" type="text/javascript"></script>
</head>
<body>
    <form id="form1" runat="server">
    <div class="center">
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Width="100%"
            border="0" CellPadding="0" >
            <Columns>
                <asp:BoundField DataField="Empid" HeaderText="Empid">
                    <ItemStyle CssClass="left" />
                </asp:BoundField>
                <asp:BoundField DataField="Empname" HeaderText="Empname">
                    <ItemStyle CssClass="left" />
                </asp:BoundField>
                <asp:BoundField DataField="City" HeaderText="City">
                    <ItemStyle CssClass="left" />
                </asp:BoundField>
            </Columns>
        </asp:GridView>
    </div>
    </form>
    <script type="text/javascript">
       $(function () {
             $('#<%=GridView1.ClientID %>').colResizable({
                liveDrag: true,
                gripInnerHtml: "<div class='grip'></div>",
                draggingClass: "dragging",
            });
        });
    </script>
</body>
</html>

Step 2 : Your .cs page:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
/// <summary>
/// Summary description for DataHelper
/// </summary>
public class DataHelper
{
    Employee employee = new Employee();
         public DataHelper()
         {
                 //
                 // TODO: Add constructor logic here
                 //
         }
    public List<Employee> GetEmployeeData()
    {
        List<Employee> emplist = new List<Employee>();
        for (int i = 1; i <= 25; i++)
        {
            employee = new Employee();
            employee.Empid = i;
            employee.Empname = "Employee " + i.ToString();
            employee.City = "City Name " + i.ToString();
            emplist.Add(employee);
        }
        return emplist;
    }
}
