Get Data from Gridview into Datatable in Asp.net using C#, VB.NET

Apr 28, 2015
Introduction

Here I will explain how to get data from
gridview to datatable in asp.net using c#, vb.net or fetch or get gridview data and insert into datatable in asp.net or get gridview data into dataset using c#, vb.net with example.


To get data from gridview and insert into datatable we need to write the code like as shown below

C# Code


DataTable dt = new DataTable();
dt.Columns.Add("userid", typeof(int));
dt.Columns.Add("username", typeof(string));
dt.Columns.Add("firstname", typeof(string));
dt.Columns.Add("lastname", typeof(string));
dt.Columns.Add("designation", typeof(string));
foreach (GridViewRow row in gvDetails.Rows)
{
int userid = int.Parse(row.Cells[0].Text);
string firstname = row.Cells[1].Text;
string lastname= row.Cells[2].Text;
string username = row.Cells[3].Text;
string designation = row.Cells[4].Text;
dt.Rows.Add(userid,username,firstname, lastname, designation);
}

VB.NET Code


Dim dt As New DataTable()
dt.Columns.Add("userid", GetType(Integer))
dt.Columns.Add("username", GetType(String))
dt.Columns.Add("firstname", GetType(String))
dt.Columns.Add("lastname", GetType(String))
dt.Columns.Add("designation", GetType(String))
For Each gvrow As GridViewRow In gvDetails.Rows
'Find checkbox control in gridview for particular row
Dim chkSelect As CheckBox = DirectCast(gvrow.FindControl("chkSelect"), CheckBox)
'Condition to check checkbox selected or not
If chkSelect.Checked Then
Dim userid As Integer = Integer.Parse(gvrow.Cells(1).Text)
Dim username As String = gvrow.Cells(2).Text
Dim firstname As String = gvrow.Cells(3).Text
Dim lastname As String = gvrow.Cells(4).Text
Dim designation As String = gvrow.Cells(5).Text
dt.Rows.Add(userid, username, firstname, lastname, designation)
End If
Next

If you want to check it in complete example first design one table EmployeeInfo in your database as shown below


Now create one new web application and open your aspx page and write the code like as shown below


<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Insert Gridview Data to Database in Asp.net using SQLBulkCopy</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="gvDetails" runat="server">
<HeaderStyle BackColor="#df5015" Font-Bold="true" ForeColor="White" />
</asp:GridView>
</div><br />
<asp:Button ID="btnInsert" runat="server" Text="Insert Gridview Data"
Font-Bold="true" onclick="btnInsert_Click" /><br />
<asp:Label ID="lblMsg" runat="server"/>
</form>
</body>
</html>

Now right click on your application à Select Add New Item à Select XML file à Give name as “sample.xml” and click OK

Once we add xml file open it and write code like as shown below


<?xml version="1.0" encoding="utf-8" ?>
<users>
<user>
<userid>1</userid>
<FirstName>Suresh</FirstName>
<LastName>Dasari</LastName>
<UserName>SureshDasari</UserName>
<Designation>Team Leader</Designation>
</user>
<user>
<userid>2</userid>
<FirstName>Mahesh</FirstName>
<LastName>Dasari</LastName>
<UserName>MaheshDasari</UserName>
<Designation>Software Developer</Designation>
</user>
<user>
<userid>3</userid>
<FirstName>Madhav</FirstName>
<LastName>Yemineni</LastName>
<UserName>MadhavYemineni</UserName>
<Designation>Business Analyst</Designation>
</user>
</users>

After completion of xml file now open aspx page codebehind behind file and add following namespaces

C# Code


using System;
using System.Data;
using System.Web.UI.WebControls;
using System.Data.SqlClient;

After completion of adding namespaces you need to write the code like as shown below


DataTable dt = new DataTable();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
//Bind Data to Gridview
GetXMLData();
}
}
// This method is used to get xml node values and bind to gridview
protected void GetXMLData()
{
DataSet ds = new DataSet();
ds.ReadXml(Server.MapPath("Sample.xml"));
dt = ds.Tables[0];
gvDetails.DataSource = dt;
gvDetails.DataBind();
}
// Insert data in database using SqlBulkCopy
protected void btnInsert_Click(object sender, EventArgs e)
{
String strConnection = "Data Source=Suresh;Initial Catalog=MySampleDB;Integrated Security=True";
DataTable dt = new DataTable();
dt.Columns.Add("userid", typeof(int));
dt.Columns.Add("username", typeof(string));
dt.Columns.Add("firstname", typeof(string));
dt.Columns.Add("lastname", typeof(string));
dt.Columns.Add("designation", typeof(string));
foreach (GridViewRow row in gvDetails.Rows)
{
int userid = int.Parse(row.Cells[0].Text);
string firstname = row.Cells[1].Text;
string lastname= row.Cells[2].Text;
string username = row.Cells[3].Text;
string designation = row.Cells[4].Text;
dt.Rows.Add(userid,username,firstname, lastname, designation);
}
using (SqlConnection con = new SqlConnection(strConnection))
{
con.Open();
SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection);
//Give your Destination table name
sqlBulk.DestinationTableName = "EmployeeInfo";
sqlBulk.WriteToServer(dt);
con.Close();
}
lblMsg.Text = "Details Inserted Successfully";
lblMsg.ForeColor = System.Drawing.Color.Green;
}

VB.NET Code


Imports System.Data
Imports System.Web.UI.WebControls
Imports System.Data.SqlClient
Partial Class VBCode
Inherits System.Web.UI.Page
Private dt As New DataTable()
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
If Not IsPostBack Then
'Bind Data to Gridview
GetXMLData()
End If
End Sub
' This method is used to get xml node values and bind to gridview
Protected Sub GetXMLData()
Dim ds As New DataSet()
ds.ReadXml(Server.MapPath("Sample.xml"))
dt = ds.Tables(0)
gvDetails.DataSource = dt
gvDetails.DataBind()
End Sub
' Insert data in database using SqlBulkCopy
Protected Sub btnInsert_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim strConnection As [String] = "Data Source=Suresh;Initial Catalog=MySampleDB;Integrated Security=True"
Dim dt As New DataTable()
dt.Columns.Add("userid", GetType(Integer))
dt.Columns.Add("username", GetType(String))
dt.Columns.Add("firstname", GetType(String))
dt.Columns.Add("lastname", GetType(String))
dt.Columns.Add("designation", GetType(String))
For Each row As GridViewRow In gvDetails.Rows
Dim userid As Integer = Integer.Parse(row.Cells(0).Text)
Dim firstname As String = row.Cells(1).Text
Dim lastname As String = row.Cells(2).Text
Dim username As String = row.Cells(3).Text
Dim designation As String = row.Cells(4).Text
dt.Rows.Add(userid, username, firstname, lastname, designation)
Next
Using con As New SqlConnection(strConnection)
con.Open()
Dim sqlBulk As New SqlBulkCopy(strConnection)
'Give your Destination table name
sqlBulk.DestinationTableName = "EmployeeInfo"
sqlBulk.WriteToServer(dt)
con.Close()
End Using
lblMsg.Text = "Details Inserted Successfully"
lblMsg.ForeColor = System.Drawing.Color.Green
End Sub
End Class
