Hi, am using view state to capture last entered values but problem where i found is in Textbox change event. Textbox event in row affect other rows. How to effect textbox event only for particular textbox.

why you need text change event inside grid view it fire an event and refreshing the grid that is the reason its affecting other textbox you may handle it in client end by using javascript

I have updated my solution here by adding OnRowDataBound event in grid:

<asp:GridView ID="GridView1" runat="server"  AutoGenerateColumns="false" OnRowDataBound="GridView_RowDataBound">
    <Columns>
        <asp:BoundField DataField="Name" HeaderText="Name" />
        <asp:BoundField DataField="Country" HeaderText="Country" />
        <asp:TemplateField>
            <ItemTemplate>
                <asp:TextBox ID="TextBox1" runat="server"  /> 
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:TextBox ID="TextBox2" runat="server"  /> 
            </ItemTemplate>
        </asp:TemplateField>
        
    </Columns>
</asp:GridView>

to add javascript use this:

XML

<script type="text/javascript">
         function Handlejavascript(text1, text2) {
             document.getElementById(text2).value
             document.getElementById(text1).value = document.getElementById(text2).value;
         }
    </script>

to call this use code in .cs file

protected void GridView_RowDataBound(Object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                TextBox TextBox1 = e.Row.FindControl("TextBox1") as TextBox;
                TextBox TextBox2 = e.Row.FindControl("TextBox2") as TextBox;
                //TextBox TextBox3 = e.Row.FindControl("TextBox2") as TextBox;

                TextBox2.Attributes.Add("onchange", "Handlejavascript('" + TextBox1.ClientID + "', '" + TextBox2.ClientID + "');");
                
            }
        }

  protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
            {
                DataTable dt = new DataTable();
                dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Id", typeof(int)),
                        new DataColumn("Name", typeof(string)),
                        new DataColumn("Country",typeof(string)) });
                dt.Rows.Add(1, "VCJ", "United States");
                dt.Rows.Add(2, "Your name", "India");
                dt.Rows.Add(3, "My Name", "France");
                dt.Rows.Add(4, "Gopinath", "India");
                GridView1.DataSource = dt;
                GridView1.DataBind();
            }
        }

hope this might help you : if you want to show value pass that value as parameter in java script function
