Add dynamic row into Datagrid

I'm not sure, how you'll achieve it in your case. But I'll show you how to add a new row with a text box if you're binding your DataGrid to a DataTable: ------------Code Starts---------- *************** .aspx file ************* <%@ Page language="c#" Codebehind="DateGridTest.aspx.cs" AutoEventWireup="false" Inherits="Forum.DateGridTest" %>

Then re-bind the datagrid and in datagrid ItemDataBound event, find that blank cell and in that blank cell insert TextBox. Hope this helps.

I am using SQL server. First of all No record in the database . So the Grid will be blank and display single blank row of the text box. When User click on the add more row then one blank row insert at the bottom. When ever user will press add row. It will insert one more row with blank text box at the bottom then user filled the row. I am using dataset. I am trying to do add multiple row but I can add only one row. This is sample of the code for the reference. *********************************** using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Drawing; using System.Web; using System.Web.SessionState; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.HtmlControls; using System.Xml.Schema; using System.Data.SqlClient; using System.IO; namespace XMLApp { ///
