How to create dynamic DataTable and bind data to columns in dynamic DataTable using asp.net

In this article I will explain how to create dynamic DataTable and bind data to columns in dynamic DataTable using ASP.NET.

First Open new website , Right click and add new page with the name as DynamicallyCreateDataTable.aspx after that we need to create one new DataTable after that add columns with DataTypes and bind data to columns after that add those columns to DataTable.

Output:




Before we need to design DynamicallyCreateDataTable.aspx page design. Below is the design code

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Dynamically create datatable with Dynamic columns and bind data to GridView in asp.net</title>
</head>
<body>
<form id="form1" runat="server">
<table align="center">
<tr>
<td>
<asp:GridView ID="gvDynamicallyDataTable" runat="server" HeaderStyle-ForeColor="Maroon">
</asp:GridView>
</td>
</tr>
</table>
</form>
</body>
</html>
// add the following namespace references
using System;
using System.Data;

//After add namespaces write the following code in code behind

public partial class DynamicallyCreateDataTable : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            DynamicallyCreateDataTableGrid();
        }
    }
   
protected void DynamicallyCreateDataTableGrid()
{
// Dynamically create DataTable and Dynamic columns with datatypes
DataTable dt = new DataTable();
dt.Columns.Add("StudentID", typeof(Int32));
dt.Columns.Add("Student Name", typeof(string));
dt.Columns.Add("School Name", typeof(string));
dt.Columns.Add("Class Name", typeof(string));
dt.Columns.Add("Section Name", typeof(string));
dt.Columns.Add("Rank No", typeof(Int32));

// First record added to DataTable
DataRow dtrow = dt.NewRow();    // Create New Row
dtrow["StudentID"] = 1;            //Bind Data to Columns
dtrow["Student Name"] = "Satya";
dtrow["School Name"] = "Narayana School";
dtrow["Class Name"] = "Seventh class";
dtrow["Section Name"] = "A";
dtrow["Rank No"] = 3;
dt.Rows.Add(dtrow);

// Secound record added to DataTable
dtrow = dt.NewRow();               // Create New Row
dtrow["StudentID"] = 2;               //Bind Data to Columns
dtrow["Student Name"] = "Bharath";
dtrow["School Name"] = "Chaithanya School";
dtrow["Class Name"] = "Fifth Class";
dtrow["Section Name"] = "A";
dtrow["Rank No"] = 8;
dt.Rows.Add(dtrow);

// 3rd record added to DataTable
dtrow = dt.NewRow();              // Create New Row
dtrow["StudentID"] = 3;              //Bind Data to Columns
dtrow["Student Name"] = "Chaithanya";
dtrow["School Name"] = "Gayatri School";
dtrow["Class Name"] = "Forth Class";
dtrow["Section Name"] = "A";
dtrow["Rank No"] = 5;
dt.Rows.Add(dtrow);

// 4th record added to DataTable
dtrow = dt.NewRow();              // Create New Row
dtrow["StudentID"] = 4;              //Bind Data to Columns
dtrow["Student Name"] = "Pardhu";
dtrow["School Name"] = "Gagri School";
dtrow["Class Name"] = "Forth Class";
dtrow["Section Name"] = "A";
dtrow["Rank No"] = 10;
dt.Rows.Add(dtrow);

gvDynamicallyDataTable.DataSource = dt;
gvDynamicallyDataTable.DataBind();
}

}
