copied!<p>hi i need to modify my code a little bit. i have a page with a radio button list and a textarea. the textarea is populated when a users makes a radio button selection. </p> <p>also, when a user makes a radio button selection the url will hold an extention in the url to show which selection index number they have selection. (i.e. ?selected=0)</p> <p><a href="http://test.com/frm_Articles.aspx?selected=0" rel="nofollow">http://test.com/frm_Articles.aspx?selected=0</a> http://test.com/frm_Articles.aspx?selected=1 <a href="http://test.com/frm_Articles.aspx?selected=2" rel="nofollow">http://test.com/frm_Articles.aspx?selected=2</a></p> <p>that way they can copy the url and reference it in other websites as a link. or place it in their favorites. </p> <p><strong>the problem is,</strong> if you grab the url and open a new browser, the page does not pass the value and databind accordingly. no radio buttons or content appear on the page. must be the postback logic i think???</p> <p>what's working:</p> <ol> <li>when i launch the website the radio buttons appear and index 0 is set </li> <li>when i select radio buttons the correct data displays and urls linking to radio button values display in browser (i.e. <a href="http://test.com/test.aspx?selected=2" rel="nofollow">http://test.com/test.aspx?selected=2</a>)</li> <li>if i cut and paste pointer urls within the same browser then correct data is rendered</li> </ol> <p>what doesn't work (everything that deal with an false PostBack):</p> <p>1.when i launch website no data within the textarea apprears even though the radio button is set to 0 index and is visiable. 2. if i cut and paste pointer url into a new browser, text area and radio buttons do not display. </p> <pre><code> protected void Page_Load(object sender, EventArgs e) { if (Page.IsPostBack == false) { int selected; if (Request.QueryString["selected"] != null) { if (int.TryParse(Request.QueryString["selected"], out selected)) { RadioButtonList1.SelectedIndex = selected; RadioButtonList1.DataBind(); } } else { int firstart = 0; RadioButtonList1.SelectedIndex = firstart; RadioButtonList1.DataBind(); } } } protected void SqlDataSource2_Selecting(object sender, SqlDataSourceSelectingEventArgs e) { // } protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e) { try{ e.Command.Parameters["@URL_FK"].Value = Session["URL_PK"]; } catch (Exception ex) { } } protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e) { string strRedirect; strRedirect = "test.aspx?selected=" + RadioButtonList1.SelectedIndex; Response.Redirect(strRedirect); } } </code></pre>
