In this article I will explain with an example, how to bind GridView using Stored Procedure and Dapper in MySQL and ASP.Net with C# and VB.Net.
 
 

Installing Dapper package using Nuget

In order to install Dapper library using Nuget, please refer my article Install Dapper from Nuget in Visual Studio.
 
 

Database

I have made use of the following table Customers with the schema as follows.

I have already inserted few records in the table.

HTML Markup

The HTML Markup consists of following control:
GridView – For displaying data.
The GridView consists of three BoundField columns.
<asp:GridView ID="gvCustomers" runat="server" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField DataField="CustomerId" HeaderText="Customer Id" />
        <asp:BoundField DataField="Name" HeaderText="Name" />
        <asp:BoundField DataField="Country" HeaderText="Country" />
    </Columns>
</asp:GridView>
 
 

Namespaces

You will need to import the following namespaces.
C#
using Dapper;
using System.Data;
using System.Configuration;
using MySql.Data.MySqlClient;
 
VB.Net
Imports Dapper
Imports System.Data
Imports System.Configuration
Imports MySql.Data.MySqlClient
 
 

Selecting using Dapper from MySQL Database in ASP.Net

Inside the Page Load event handler, first the connection is read from Web.Config file.
Note: For more details on how to read connection string from Web.Config file, please refer my article Read or Write Connection Strings in Web.Config file using ASP.Net using C# and VB.Net.
 
Then, a connection to the database is established using the MySqlConnection class.
Then, using ExecuteReader method of Dapper library, the records are fetched from the Customers Table and copied to DataTable object using Load method.
Note: For more details on how to use ExecuteReader, please refer my article Using Dapper ExecuteReader in MySQL in C# and VB.Net.
 
Finally, the DataTable is assigned to the DataSource property of GridView and DataBind method is called.
C#
protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        string sql = "SELECT CustomerId, Name, Country FROM Customers";
        string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
        using (MySqlConnection con = new MySqlConnection(constr))
        {
            using (IDataReader sdr = con.ExecuteReader(sql))
            {
                using (DataTable dtCustomers = new DataTable())
                {
                    dtCustomers.Load(sdr);
                    gvCustomers.DataSource = dtCustomers;
                    gvCustomers.DataBind();
                }
            }
        }
    }
}
 
VB.Net
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    If Not Me.IsPostBack Then
        Dim sql As String = "SELECT CustomerId, Name, Country FROM Customers"
        Dim constr As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
        Using con As MySqlConnection = New MySqlConnection(constr)
            Using sdr As IDataReader = con.ExecuteReader(sql)
                Using dtCustomers As DataTable = New DataTable()
                    dtCustomers.Load(sdr)
                    gvCustomers.DataSource = dtCustomers
                    gvCustomers.DataBind()
                End Using
            End Using
        End Using
    End If
End Sub
