Dynamically create datable and bind to gridview in asp.net

Mar 22, 2012
Introduction:

In this article I will explain how to create datatable and bind data to columns in datatable dynamically using asp.net.


Description:

In Previous posts I explained lot of articles regarding
Asp.net, Gridview, SQL Server, Ajax, JavaScript etc. In many of articles I used datatable to bind data from database but in one situation I got requirement like dynamically build and bind data to datatable in asp.net.

To implement this requirement we need to create one new datatable after that add columns and bind data to columns after that add those columns to datatable before that first create new website open Default.aspx page and write the following code 

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Dynamically create datatable and bind data to it in asp.net</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="gvDetails" runat="server">
</asp:GridView>
</div>
</form>
</body>
</html>
After that open code behind page and add the following namespace references


using System;
using System.Data;
After add namespaces write the following code in code behind

C# code


protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
BindGridviewData();
}
}
/// <summary>
/// Dynamically create & bind data to datatable and bind datatable to gridview
/// </summary>
protected void BindGridviewData()
{
DataTable dt = new DataTable();
dt.Columns.Add("UserId", typeof(Int32));
dt.Columns.Add("UserName", typeof (string));
dt.Columns.Add("Education", typeof (string));
dt.Columns.Add("Location",typeof(string));

DataRow dtrow = dt.NewRow();    // Create New Row
dtrow["UserId"] = 1;            //Bind Data to Columns
dtrow["UserName"] = "SureshDasari";
dtrow["Education"] = "B.Tech";
dtrow["Location"] = "Chennai";
dt.Rows.Add(dtrow);

dtrow = dt.NewRow();               // Create New Row
dtrow["UserId"] = 2;               //Bind Data to Columns
dtrow["UserName"] = "MadhavSai";
dtrow["Education"] = "MBA";
dtrow["Location"] = "Nagpur";
dt.Rows.Add(dtrow);

dtrow = dt.NewRow();              // Create New Row
dtrow["UserId"] = 3;              //Bind Data to Columns
dtrow["UserName"] = "MaheshDasari";
dtrow["Education"] = "B.Tech";
dtrow["Location"] = "Nuzividu";
dt.Rows.Add(dtrow);

dtrow = dt.NewRow();              // Create New Row
dtrow["UserId"] = 4;              //Bind Data to Columns
dtrow["UserName"] = "Mahendra";
dtrow["Education"] = "CA";
dtrow["Location"] = "Guntur";
dt.Rows.Add(dtrow);
gvDetails.DataSource = dt;
gvDetails.DataBind();
}
VB.NET Code


Imports System
Imports System.Data
Partial Class Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load

If Not IsPostBack Then
BindGridviewData()
End If
End Sub
' Dynamically create & bind data to datatable and bind datatable to gridview
Protected Sub BindGridviewData()
Dim dt As New DataTable()
dt.Columns.Add("UserId", GetType(Int32))
dt.Columns.Add("UserName", GetType(String))
dt.Columns.Add("Education", GetType(String))
dt.Columns.Add("Location", GetType(String))

Dim dtrow As DataRow = dt.NewRow()
' Create New Row
dtrow("UserId") = 1
'Bind Data to Columns
dtrow("UserName") = "SureshDasari"
dtrow("Education") = "B.Tech"
dtrow("Location") = "Chennai"
dt.Rows.Add(dtrow)

dtrow = dt.NewRow()
' Create New Row
dtrow("UserId") = 2
'Bind Data to Columns
dtrow("UserName") = "MadhavSai"
dtrow("Education") = "MBA"
dtrow("Location") = "Nagpur"
dt.Rows.Add(dtrow)

dtrow = dt.NewRow()
' Create New Row
dtrow("UserId") = 3
'Bind Data to Columns
dtrow("UserName") = "MaheshDasari"
dtrow("Education") = "B.Tech"
dtrow("Location") = "Nuzividu"
dt.Rows.Add(dtrow)

dtrow = dt.NewRow()
' Create New Row
dtrow("UserId") = 4
'Bind Data to Columns
dtrow("UserName") = "Mahendra"
dtrow("Education") = "CA"
dtrow("Location") = "Guntur"
dt.Rows.Add(dtrow)
gvDetails.DataSource = dt
gvDetails.DataBind()
End Sub
End Class
