  How do i create the right url? (including Request.Querystring)

  Sep 16, 2008 04:50 PM|LINK

   

   Hi!

  I got 2 imagebuttons. When I click imagebutton "melk", i want response.redirect to have the url Default.aspx?anledning=an&matintoleranse=melk.
  

  Then, when I click imagebutton "egg", I want the url to show Default?aspx?anledning=an&matintoleranse=melk&mati ntoleranse=egg
  

  Then, when I click imagebutton "egg" again, I want the url to show
  Default?aspx?anledning=an&matintoleranse=melk
  

  Unfortunately, my code does not show it, but instead it shows Default.aspx?anledning=an&matintoleranse=melk,e gg&matintoleranse=melk when i click "egg" again.

  What's wrong?

    

  protected void imgBtnMelk_Click(object sender, System.Web.UI.ImageClickEventArgs e)
      {
          string anledning = lblanledning.Text;
          string url = "Default.aspx?anledning=an";
          string check = "empty";
  
          foreach (string var in Request.QueryString)
          {
              if (Request.QueryString[var] != "" & var == "matintoleranse"
                  & Request.QueryString[var] != "melk")
              {
                  url += "&matintoleranse=" + Request.QueryString[var];
              }
              if (Request.QueryString[var] == "melk")
              {
                  check = "removed";
              }
          }
          if (check != "removed")
          {
              url += "&matintoleranse=melk";
          }
          Response.Redirect(url);
      }
      protected void imgBtnEgg_Click(object sender, System.Web.UI.ImageClickEventArgs e)
      {
  
          string anledning = lblanledning.Text;
          string url = "Default.aspx?anledning=an";
          string check = "empty";
  
          foreach (string var in Request.QueryString)
          {
              if (Request.QueryString[var] != "" & var == "matintoleranse"
                  & Request.QueryString[var] != "egg")
              {
                  url += "&matintoleranse=" + Request.QueryString[var];
              }
              if (Request.QueryString[var] == "egg")
              {
                  check = "removed";
              }
          }
          if (check != "removed")
          {
              url += "&matintoleranse=egg";
          }
          Response.Redirect(url);
      }

   Hi!

  I got 2 imagebuttons. When I click imagebutton "melk", i want response.redirect to have the url Default.aspx?anledning=an&matintoleranse=melk.
  

  Then, when I click imagebutton "egg", I want the url to show Default?aspx?anledning=an&matintoleranse=melk&mati ntoleranse=egg
  

  Then, when I click imagebutton "egg" again, I want the url to show
  Default?aspx?anledning=an&matintoleranse=melk
  

  Unfortunately, my code does not show it, but instead it shows Default.aspx?anledning=an&matintoleranse=melk,e gg&matintoleranse=melk when i click "egg" again.

  Hi dolli,

  Based on my understanding, what you need is that according to the order of the ImageButton clicked like imgBtnMelk -> imgBtnEgg -> imgBtnEgg, the URL should display in this train:

   

    1. Default.aspx?anledning=an&matintoleranse=melk

    2. Default.aspx?anledning=an&matintoleranse=melk&matintoleranse=egg
          (I deleted the space might be unexpected in the last matintoleranse and changed the question mark to dot between Default and aspx)

    3. Default.aspx?anledning=an&matintoleranse=melk
          (Also changed the question mark to dot between Default and aspx)

  If I have misunderstood you, please feel free to let me know.

  However, the last URL you get now is "Default.aspx?anledning=an&matintoleranse=melk,egg&matintoleranse=egg" which makes the mistake.

  I think the problem is caused by the if statement gives a wrong judgement at line 35. When the QueryString has more than one parameter with the same name, it will return a string list splited with the comma, like "melk,egg" in your condition for example.

  So, I suggest you modifying the code in line 35 to the one below and have another try.

  34               if (Request.QueryString[var] != "" & var == "matintoleranse"
  35                   & !Request.QueryString[var].Split(",".ToCharArray()).Contains("egg"))

  Best Regards,
  Shengqing Yang

  hi doli,

  Here is the solution... I did it in vb... i'm sure you can easily convert it into C#....

   

  Partial Class Default
      Inherits System.Web.UI.Page
          Dim strquery As String
  
  
  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
       strquery = Request.ServerVariables("QUERY_STRING")
  End Sub
  
  
  Protected Sub ImageButton1_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton1.Click
          Response.Redirect("Default.aspx?anledning=an&matintoleranse=melk")
      End Sub
  
  
  Protected Sub ImageButton2_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton2.Click
  
  
          If (strquery.Contains("matintoleranse=melk") And Not strquery.Contains("matintoleranse=egg")) Then
              Response.Redirect("Default.aspx?anledning=an&matintoleranse=melk&matintoleranse=egg")
          ElseIf strquery.Contains("matintoleranse=egg") Then
              Response.Redirect("Default.aspx?anledning=an&matintoleranse=melk")
          ElseIf strquery = "" Then
              Response.Redirect("Default.aspx?anledning=an&matintoleranse=melk")
          End If
  
  
  End Sub
  End Class

   Hope this helped you...

   

  Thanks
  Swapna

  To Shengqing Yang - MSFT: You understood correctly. I tried your code, and it says System.Array does not contain a definition for Contains.

  To swapnasamsonvarkey: I need the code more smooth because in reality there's more imagebuttons, but thanks for trying.

   

  Conclusion:  I wish this code would work, so if you still would like to help me make it work, then I'll follow it up.

  Anyway, I got the answer to this problem in another format.
