Create Data table dynamically using code in asp.net

In this I will explain how we can create a dynamic table in Asp.NET (Server side). Suppose we want to show data in gridview from temporary dynamic table created in server side.

Design Section:

<asp:GridView ID="grdbook" runat="server">

        <HeaderStyle Font-Bold="true"/>

        </asp:GridView>

ASP.NET Code:

using System.Data;

protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            Bindgrid();

        }

    }

    public void Bindgrid()

    {

        try

        {

            DataTable dt = new DataTable();

            dt.Columns.Add("EmpId", typeof(Int32));

            dt.Columns.Add("Emp Name", typeof(string));

            dt.Columns.Add("Salary", typeof(int));

            dt.Rows.Add(1, "Ajay", 12300);

            dt.Rows.Add(2, "Ankush", 15000);

            dt.Rows.Add(3, "Aman", 19900);

            dt.Rows.Add(4, "Vijay", 29900);

            dt.Rows.Add(5, "Mayank", 39900);

            dt.Rows.Add(6, "Aman Sharma", 14900);

            grdbook.DataSource = dt;

            grdbook.DataBind();

        }

        catch (Exception ex)

        {

        }       

    }

VB Code:

Imports System.Data

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) HandlesMe.Load

        If Not IsPostBack Then

            Bindgrid()

        End If

    End Sub

    Public Sub Bindgrid()

        Try

            Dim dt As New DataTable()

            dt.Columns.Add("EmpId", GetType (Int32))

            dt.Columns.Add("Emp Name", GetType (string))

            dt.Columns.Add("Salary", GetType (int))

            dt.Rows.Add(1, "Ajay", 12300)

            dt.Rows.Add(2, "Ankush", 15000)

            dt.Rows.Add(3, "Aman", 19900)

            dt.Rows.Add(4, "Vijay", 29900)

            dt.Rows.Add(5, "Mayank", 39900)

            dt.Rows.Add(6, "Aman Sharma", 14900)

            grdbook.DataSource = dt

            grdbook.DataBind()

        Catch ex As Exception

        End Try

    End Sub
