Introduction:
In this post I will tell you how to bind the Listview data control in Asp.net.
Description:
I have created
a table name STUDENT_DETAIL.
STUDENT_ID
|
int
|
STUDENT_NAME
|
varchar(50)
|
STUDENT_ADDRESS
|
varchar(50)
|
STUDENT_CLASS
|
varchar(50)
|
STUDENT_ID is primary key.
Now open the Visual Studio>Go to File>New>Website. Add
the Connectionstring in web.config file of website.
<configuration>
<connectionStrings>
<add name="connection" connectionString="Data Source=SYS-1F78031ED0A;Initial
Catalog=TestBlog;Integrated Security=True"/>
</connectionStrings>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
</configuration>
After that add new web form to website, drag and drop the
Listview Data control from Toolbox.
<asp:ListView ID="liststudent"
runat="server"
DataKeyNames="STUDENT_ID">
<LayoutTemplate>
<table style="margin:0px auto;border:1px solid #c1c1c1;">
<tr style="background-color:#E5E5FE;font-weight:bold">
<td align="left"><asp:Label ID="lblstudent"
runat="server">Student
Name</asp:Label></td>
<td align="left"><asp:Label ID="lblstudentaddress"
runat="server">Student
Address</asp:Label></td>
<td align="left"><asp:Label ID="lblstudentclass"
runat="server">Student
Class</asp:Label></td>
</tr>
<tr id="itemPlaceholder" runat="server"></tr>
</LayoutTemplate>
<ItemTemplate>
<tr style="background-color: #E0FFFF; color: #333333;font-style:italic;text-align:center;">
<td> <asp:Label ID="lblstudentname"
runat="server"
Text='<%#Eval("STUDENT_NAME")%>'></asp:Label></td>
<td><asp:Label ID="lbladdress" runat="server" Text='<%#Eval("STUDENT_ADDRESS") %>'></asp:Label></td>
<td><asp:Label ID="lblclass" runat="server" Text='<%#Eval("STUDENT_CLASS") %>'></asp:Label></td></tr>
</ItemTemplate>
<EmptyDataTemplate>
<table border="1">
<tr style="color:Red;"><td
align="center">
<asp:Label ID="lblmessage" runat="server" Text="No Data Found"></asp:Label></td></tr></table>
</EmptyDataTemplate>
</asp:ListView>
After that go to
.aspx.cs page and add namespace.
using
System.Data;
using
System.Data.SqlClient;
using
System.Configuration;
Create a function to
bind Listview.
SqlConnection con
= new SqlConnection(ConfigurationManager.ConnectionStrings["connection"].ToString());
protected void Page_Load(object
sender, EventArgs e)
{
if
(con.State == ConnectionState.Closed)
con.Open();
if
(!IsPostBack)
{
bindListview();
}
}
private void bindListview()
{
try
{
SqlDataAdapter
adp = new SqlDataAdapter("select * from STUDENT_DETAIL", con);
DataTable
dt = new DataTable();
adp.Fill(dt);
if
(dt.Rows.Count > 0)
{
liststudent.DataSource = dt;
liststudent.DataBind();
}
else
{
liststudent.DataSource = null;
Response.Write("No Records Available");
}
}
catch (Exception ex)
{
}
}
In VB
Go to .aspx.vb page
and add namespace.
Imports
System.Data
Imports
System.Data.SqlClient
Imports
System.Configuration
Private con
As New SqlConnection(ConfigurationManager.ConnectionStrings("connection").ToString())
Protected Sub Page_Load(ByVal
sender As Object,
ByVal e As
System.EventArgs) Handles
Me.Load
If
con.State = ConnectionState.Closed Then
con.Open()
End If
If Not IsPostBack Then
bindListview()
End If
End Sub
Private Sub bindListview()
Try
Dim
adp As New SqlDataAdapter("select
* from STUDENT_DETAIL", con)
Dim
dt As New DataTable()
adp.Fill(dt)
If
dt.Rows.Count > 0 Then
liststudent.DataSource = dt
liststudent.DataBind()
Else
liststudent.DataSource = Nothing
Response.Write("No Records Available")
End
If
Catch
ex As Exception
End Try
Now debug the project
and check the result.
