Deleted rows reappear in databale and gridview

[Suraj p]

Hi!!!
following is complete code for adding and deleting rows from grid view.

using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Windows.Forms;
 
public partial class _Default : System.Web.UI.Page 
{
    public static DataTable dt;
    public static DataTable dt1;
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            dt = new DataTable();
 
            DataColumn dc = new DataColumn("EName");
 
            dt.Columns.Add(dc);
 
            DataColumn dc1 = new DataColumn("EID");
 
            dt.Columns.Add(dc1);
 
        } 
   }
    protected void Button1_Click(object sender, EventArgs e)
    {
 
        GridView1.DataSource = dt;
        GridView1.DataBind();
 
 
        if (ViewState["myTable"] != null)
        {
            dt = ViewState["myTable"] as DataTable;
        }
        ViewState["myTable"] = dt;
        DataRow dr = dt.NewRow();
        dr["EName"] = TextBox1.Text.ToString();
        dr["EID"] = TextBox1.Text.ToString();
        dt.Rows.Add(dr);
        //dt.Rows.Remove(GridView1.DataKey.)
       // GridViewDeleteEventHandler 
        dt1 = (DataTable)ViewState["myTable"];
        GridView1.DataSource = dt1;
      //  GridView1.DeleteRow(e.RowIndex);
        GridView1.DataBind();
 
    }
 
 
 
    protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {
 
    }
 
    protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        dt1.Rows.RemoveAt(e.RowIndex);
        GridView1.DataSource = dt1;
        GridView1.DataBind();
    }
}

But after deleting rows from grid view it reappears.
Kindly reply.

You deleted the row from dt1 but then didn't store dt1 back into your ViewState...so the next time you retrieve dt1 from ViewState it will still contain the row.
