just have look guys and solve the problems as soon as possible


Default.aspx

have used two hidden fields and they are hdn1 and hdn2 and gridview i didnt add the columns directly to add gridview every things is done in programmatically



public partial class _Default : System.Web.UI.Page 
{
    DataSet ds = new DataSet();
    public string datatablename = "empdata";
    DataTable dt;
    DataView dv;
    DataRow dr;
    DataColumn dc;
    public string dc0,dc1,dc2;


    protected void Page_Load(object sender, EventArgs e)
    {
        designcols();
        Button1.Attributes.Add("onclick", "window.open('Default2.aspx',null,'left=400px,top=400,height=100px,width-250,status=no,resizable=no,scrollbars=no;toolbar=no,location=no,menubar=no');");
        loadval();
       
    }

    public void designcols()
    {
        dt = new DataTable(datatablename);
        dc = dt.Columns.Add("EMP", typeof(string));
        dt.Columns.Add("empname",typeof(string));
        dt.Columns.Add("Empaddr", typeof(string));
        ds.Tables.Add(dt);
        //dr = dt.NewRow();
        //ds.Tables[datatablename].Rows.Add(dr);        
    }
    public void loadval()
    {
        

            if (ViewState["datatablename"] != null)
            {
                DataTable Tempdt = new DataTable();
                Tempdt = ViewState["datatablename"] as DataTable;
                dt = Tempdt.Copy();
            }
            dr = dt.NewRow();
            dr[0] = hdn1.Value;
            dr[1] = hdn2.Value;
            dr[2] = dc2;
            dt.Rows.Add(dr);
            ViewState["datatablename"] = dt;
            dv = new DataView(dt);
            GridView1.DataSource = dv;
            GridView1.DataBind();
       

    }

Default2.aspx in html page i wrote this

Two textbox as textbox1 and textbox2

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Untitled Page</title>
    <script type="text/javascript">
    function passvalue()
    {
    
    window.opener.document.getElementById("hdn1").value=document.getElementById("<%=TextBox1.ClientID %>").value;
    window.opener.document.getElementById("hdn2").value=document.getElementById("<%=TextBox2.ClientID %>").value;
    window.self.close();  
    }    
    </script>
</head>

protected void Page_Load(object sender, EventArgs e)
    {
        Button1.Attributes.Add("onclick", "passvalue();");

try this code for which i had done in my computer i'm using textbox you can use any thing as per you want

private void BindGrid(int rowcount)
{
        DataTable dt = new DataTable();
        DataRow dr;
        dt.Columns.Add(new System.Data.DataColumn("TextBox1Column", typeof(String)));
        dt.Columns.Add(new System.Data.DataColumn("TextBox2Column", typeof(String)));
        dt.Columns.Add(new System.Data.DataColumn("TextBox3Column", typeof(String)));
 
        if (ViewState["CurrentData"] != null)
        {
            for (int i = 0; i < rowcount + 1; i++)
            {
                dt = (DataTable)ViewState["CurrentData"];
                if (dt.Rows.Count > 0)
                {
                    dr = dt.NewRow();
                    dr[0] = dt.Rows[0][0].ToString();
 
                }
            }
            dr = dt.NewRow();
            dr[0] = TextBox1.Text;
            dr[1] = TextBox2.Text;
            dr[2] = TextBox3.Text;
            dt.Rows.Add(dr);
 
        }
        else
        {
            dr = dt.NewRow();
            dr[0] = TextBox1.Text;
            dr[1] = TextBox2.Text;
            dr[2] = TextBox3.Text;
 
            dt.Rows.Add(dr);
 
        }
 
        // If ViewState has a data then use the value as the DataSource
        if (ViewState["CurrentData"] != null)
        {
            GridView1.DataSource = (DataTable)ViewState["CurrentData"];
            GridView1.DataBind();
        }
        else
        {
        // Bind GridView with the initial data assocaited in the DataTable
            GridView1.DataSource = dt;
            GridView1.DataBind();
 
        }
        // Store the DataTable in ViewState to retain the values
        ViewState["CurrentData"] = dt;
 
    }

Binding the GridView on Button_Click event

protected void Button1_Click(object sender, EventArgs e)
    {
        // Check if the ViewState has a data assoiciated within it. If 
        if (ViewState["CurrentData"] != null)
        {
            DataTable dt = (DataTable)ViewState["CurrentData"];
            int count = dt.Rows.Count;
            BindGrid(count);
        }
        else
        {
            BindGrid(1);
        }
        TextBox1.Text = string.Empty;
 
        TextBox1.Focus();
}
