Post Data from child popup to parent Form (With out refreshing parent Form)

I have two textbox and one button in parent form with caption OPEN child. I had entered data in one textbox. for other textbox i want to take data from child popup which will open on clicking the button. In child popup, I have one textbox and one button. The data which will be entered in this textbox will come in parent textbox on clicking button. Data is coming from child popup but the parent form is getting refreshed which i dont want. I want data to remain intact in first textbox when data will come in other textbox throgh child popup. Plese give me a suggestion.

            <table>
                <tr>
                    <td>First Name:</td>
                    <td><asp:TextBox ID="txtName1" Runat="server"></asp:TextBox></td>
                </tr>
                <tr>
                    <td>Qualification:</td>
                    <td><asp:TextBox ID="txtName2" Runat="server"></asp:TextBox></td>
                </tr>

                <tr>
                    <td align="center" colspan="2">
                    <asp:Button ID="btnSubmit" Runat="server" PostBackUrl="Sample2.aspx" Text="Submit" /></td>
                </tr>
            </table>
        </form>
    </body>
</html>

    //-- If posted from Sample1.aspx to Sample2.aspx page
    if (PreviousPage != null)

        if (PreviousPage.IsCrossPagePostBack)
        {
            //-- Retrieve the textbox values from Previous page using FindControl method

            TextBox TextBox2;



            TextBox2 = (TextBox)PreviousPage.FindControl("txtName2");

           TextBox2.Text = "MBBS";//This value should be in textbox2 in sample page1 without lossing value of textbox1
        }
        else
        {
            Response.Redirect("Sample1.aspx");
        }
    }
}

Thanks in advance.

You can do that using Javascript
For example i have a Button and when button click i open popup and return the data to main page.

For the Button client click event i have used this in page init method
Here i call the javascript method in onclick client event and also i pass the text box to the java script function to display back the popup result.

C#

imgTool.Attributes.Add("onclick", string.Format("popupOpen({0})", txtbox1.ClientID));

This is javascript code which you can add in your main page and this scriipt will a popop window.kindly change the page name to your popup aspx window.

JavaScript

function popupOpen(textbox_id) {
    if (project_id.disabled || project_id.getAttribute('ReadOnly')) return false;
    var res = ShowPopup("popUpPage.aspx?project_id=" + project_id.value, 820, 551);
    if (!!res) {
        textbox.value = res[0];
       // if (!!car_cd) textbox.value = res[1]; 
    }
}

In you Popup Page you can have close Button and in Close Button Click.pass the result which need to be display in your main page.

C#

protected void btnConfirm_Click(object sender, ImageClickEventArgs e)
    {
        SelectConfirm("Shanu");
    }
 protected void SelectConfirm(yourreturnvalue)
    { 
     Response.Write("<script language='javascript'>");
        Response.Write("window.returnValue = new Array('" +
       yourreturnvalue  + "');window.close();");               
     Response.Write("</script>");
    }
