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.
Description:
In previous articles I explained insert selected gridview rows into database in asp.net, take database backup in sql server 2008, encrypt and decrypt passwords in sql server 2008, Google Map show info windows when click on marker in asp.net, Delete multiple rows in gridview using checkbox in asp.net and many articles relating to gridview, asp.net, c#,vb.net and jQuery. Now I will explain how get data from gridview to datatable in asp.net using c#, vb.net.

Now I will explain how get data from gridview to datatable in asp.net using c#, vb.net.
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 Ã
Select Add New Item à Select XML file Ã
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
