Introduction:
Here I will explain how to bind data from datatable to gridview in asp.net using c#, vb.net with example or display data from datatable to asp.net gridview from database in c#, vb.net with example.
Description:
In previous articles I explained gridview examples in asp.net, bind dropdownlist in asp.net gridview using dataset, validate textbox controls inside gridview in asp.net, cascading dropdownlist in gridview using asp.net, change gridview header dynamically 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 to bind gridview in asp.net using datatable in c#, vb.net with example.

Now I will explain how to bind gridview in asp.net using datatable in c#, vb.net with example.
Before
implement this example first design one table productinfo in your database as
shown below
Column Name
|
Data Type
|
Allow Nulls
|
productid
|
Int(IDENTITY=TRUE)
|
Yes
|
productname
|
varchar(50)
|
Yes
|
price
|
varchar(50)
|
Yes
|
Once
table created in database enter some dummy data to test application now open
your aspx page and write the code like as shown below
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"
runat="server">
<title>Bind data to gridview
in asp.net using c#, vb.net</title>
<style type="text/css">
.GridviewDiv {font-size: 100%; font-family: 'Lucida
Grande', 'Lucida Sans Unicode', Verdana, Arial, Helevetica, sans-serif;
color: #303933;}
.headerstyle
{
color:#FFFFFF;border-right-color:#abb079;border-bottom-color:#abb079;background-color:
#df5015;padding:0.5em 0.5em 0.5em 0.5em;text-align:center;
}
</style>
</head>
<body>
<form id="form1"
runat="server">
<div class="GridviewDiv">
<asp:GridView runat="server"
ID="gvDetails"
AllowPaging="true"
PageSize="10"
AutoGenerateColumns="false"
Width="420px"
OnPageIndexChanging="gvDetails_PageIndexChanging">
<HeaderStyle CssClass="headerstyle"
/>
<Columns>
<asp:BoundField DataField="productid"
HeaderText="Product
Id" />
<asp:BoundField DataField="productname"
HeaderText="Product
Name" />
<asp:BoundField DataField="price"
HeaderText="Price"
/>
</Columns>
</asp:GridView>
</div>
</form>
</body>
</html>
|
After completion of aspx page add following namespaces in
codebehind
C#
Code
using System;
using
System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;
|
After completion of adding namespaces you need to write the
code like as shown below
protected void Page_Load(object
sender, EventArgs e)
{
if (!IsPostBack)
{
BindGridview();
}
}
protected void BindGridview()
{
DataSet ds = new DataSet();
using (SqlConnection con = new
SqlConnection("Data
Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB"))
{
con.Open();
SqlCommand cmd = new SqlCommand("select * from productinfo", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
con.Close();
gvDetails.DataSource
= dt;
gvDetails.DataBind();
}
}
protected void gvDetails_PageIndexChanging(object sender, GridViewPageEventArgs
e)
{
gvDetails.PageIndex = e.NewPageIndex;
BindGridview();
}
|
VB.NET
Code
Imports
System.Web.UI.WebControls
Imports System.Data
Imports System.Data.SqlClient
Partial Class VBCode
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal
sender As Object,
ByVal e As EventArgs) Handles
Me.Load
If Not
IsPostBack Then
BindGridview()
End If
End Sub
Protected Sub BindGridview()
Dim ds As New DataSet()
Using con As New SqlConnection("Data
Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB")
con.Open()
Dim cmd As New SqlCommand("select
* from productinfo", con)
Dim da As New SqlDataAdapter(cmd)
Dim dt As New DataTable()
da.Fill(dt)
con.Close()
gvDetails.DataSource
= dt
gvDetails.DataBind()End Using
End Sub
Protected Sub gvDetails_PageIndexChanging(ByVal sender As Object, ByVal e As GridViewPageEventArgs)
gvDetails.PageIndex = e.NewPageIndex
BindGridview()
End Sub
End Class
