  Panel Visibility Issue

  Apr 16, 2012 07:48 PM|LINK

  Hello!! I have an issue that I am stuck on. I have a form is sending a queryString to a page that I am accessing in my code file to determine whether or a not a panel (that contains a gridview) should be visible. For example the url being passed is: TestURL?Selection=Department. I am using a switch statement in C#. The default is being returned everytime and shouldn't be. If I comment out the default then nothing is returned.

  Here is an example of the panel:

  <asp:Panel ID="DepartmentPanel" cssclass="panel" runat="server" Visible="False">

  Here is my code in the code file:

  public partial class Department_Main : System.Web.UI.Page

  {

   

  protected void Page_Load(object sender, EventArgs e)

  {

  String ShowGrid = Request.QueryString["Selection"];

  switch (ShowGrid)

  {
  case "Department":

  DepartmentPanel.Visible =true;
  break;

  case "Building":

  BuildingPanel.Visible =true;

  break;

  default:

  DepartmentPanel.Visible =true;

  break;

  }

  }

  Can someone let me know what I am doing wrong or even a better way to accomplish this. Thanks in advance!!

  try writing your case statements like this

  case (string) "Department"

  DepartmentPanle.Visible=true;

  break;

  String ShowGrid should be string ShowGrid for starters. Have you put a breakpoint there to see what is being placed into the variable ShowGrid?

  i checked your code.. it is working fine..

  Default only returns when there is no query string or query doesn't match to any case statement..

  Thanks for the input!! I changed String to string - great catch!! I added a breakpoint to check the value in the queryString and it is null. I need to figure out why it is not passing it.

  THANKS!! I finally saw the issue. The querystring variable on the passing page was incorrect. The variable is "Section" not "Selection". Thanks for everyones help.

  Don't check like this: if(Request.QueryString["Section"].ToString()!=Null)

  THis will throw an error the second you call ToString() if there is no Section.

  You need to check to see if:

  if(Request.QueryString["Section"] != null)
