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;
}
}
Output:
