    Hi Friends,

    i am working with a  Asp.net web application using C#, it has two pages, page1 and page2.

    Page1 is having a asp.net label with some value in it like Name and a asp.net button,

    and Page2 is having a asp.net Textbox.

    on button click i want the value(Name) in label of Page1 should transfer to the  textbox of Page2.

    Even if i directly open Page2 then also, Page2 should not popup any error like null reference or some other

    Hope i have explained my issue, please help,

    Thanks all

    Use QueryString to pass value.

    In your Page1.aspx, pass label value in QueryString (encode it as well):

            protected void btnRedirect_Click(object sender, EventArgs e)
        {
            Response.Redirect("Page2.aspx?lblval=" + HttpUtility.UrlEncode(lblValue.Text));
        }

    and in your Page2.aspx in Page_Load event check for null and set value to TextBox (decode it as well):

            protected void Page_Load(object sender, EventArgs e)
        {
            //-- check for null, if this page is opened directly.
            if (null != Request.QueryString && 
                !string.IsNullOrEmpty(Request.QueryString["lblval"]))
            {
                TextBox1.Text = HttpUtility.UrlDecode(Request.QueryString["lblval"]);
            }
        }
