How to Bind FormView control using Sqldataadapter, Datatable and Query in Asp.net(C#, VB)?


Introduction: In this post I will explain you how to bind the FormView 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 FormView Data control from Toolbox.
<asp:FormView ID="formviewstudent" runat="server" DataKeyNames="STUDENT_ID" AllowPaging="True"
            onpageindexchanging="formviewstudent_PageIndexChanging">
             <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
        <RowStyle BackColor="#EFF3FB" />
        <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
        <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
            <ItemTemplate>
            <table style="border:1px solid #c1c1c1;">
            <tr style="background-color:#E5E5FE;font-weight:bold"><td>Student Detail</td></tr>
              <tr><td><b>Student Name:-</b></td><td><asp:Label ID="lblstudentname" runat="server" Text='<%# Eval("STUDENT_NAME") %>'></asp:Label></td></tr>
              <tr><td><b>Student Address:-</b></td><td><asp:Label ID="lblstudentaddress" runat="server" Text='<%# Eval("STUDENT_ADDRESS") %>'></asp:Label></td></tr>                <tr><td><b>Student Class:-</b></td><td><asp:Label ID="lblstudentclass" runat="server" Text='<%# Eval("STUDENT_CLASS") %>'></asp:Label></td></tr>
                            </table>
            </ItemTemplate>
              <EmptyDataTemplate>
            <table style="border:1px solid #c1c1c1;">
            <tr style="background-color:#E5E5FE;font-weight:bold"><td><b>Student Details</b></td></tr>
            <tr><td><b>Student Name:-</b></td><td style="color:Red;">No Records Aviable!</td></tr>
            <tr><td><b>Student Address:-</b></td><td style="color:Red;">No Records Aviable!</td></tr>
            <tr><td><b>Student Class:-</b></td><td style="color:Red;">No Records Aviable!</td></tr>
           
            </table>
            </EmptyDataTemplate>
                 </asp:FormView>
After that go to .aspx.cs page and add namespace.

using System.Data;
using System.Data.SqlClient;
using System.Configuration;

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)
        {
            Bindformview();
        }
    }
    public void Bindformview()
    {
        try
        {
            SqlDataAdapter adp = new SqlDataAdapter("Select * from STUDENT_DETAIL", con);
            DataTable dt = new DataTable();
            adp.Fill(dt);
            if (dt.Rows.Count > 0)
            {
                formviewstudent.DataSource = dt;
                formviewstudent.DataBind();
            }
            else
            {
                formviewstudent.DataSource = null;
                formviewstudent.DataBind();
            }
        }
        catch (Exception ex)
        {
        }
    }
protected void formviewstudent_PageIndexChanging(object sender, FormViewPageEventArgs e)
    {
        formviewstudent.PageIndex = e.NewPageIndex;
        Bindformview();
    }


In VB:
Go to .aspx.vb page and add namespace.

Imports System.Data
Imports System.Data.SqlClient
Imports System.Configuration

Dim 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
            Bindformview()
        End If
    End Sub
    Public Sub Bindformview()
        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
                formviewstudent.DataSource = dt
                formviewstudent.DataBind()
            Else
                formviewstudent.DataSource = Nothing
                formviewstudent.DataBind()
            End If
        Catch ex As Exception
        End Try
    End Sub

    Protected Sub formviewstudent_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewPageEventArgs) Handles formviewstudent.PageIndexChanging
        formviewstudent.PageIndex = e.NewPageIndex
        Bindformview()
    End Sub
Now debug the project and check the result.
