  Session variable

  Mar 07, 2012 05:48 PM|LINK

  I have a session variable created when you click on the treenode on the master page (sidenav). Looks like this:

  protected void sideNav_SelectedNodeChanged(object sender, EventArgs e)
  {
  
      Session["someValue"] = sideNav.SelectedNode.Value;
  
      Response.Redirect("~/Account/Profile.aspx");
  }

  Then I am trying to get the value  on the page load of that redirect. That code looks like this:

  if (Session["someValue"] != null)
  {
      IDLabel.Text = Session["someValue"].ToString();
  }

  I am getting this error... "Input string was not in a correct format." Any assistance is greatly appreciated.

  looks right. you should debug and set a breakpoint on the if statement and see what is actually inside the session variable. perhaps nothing was input in the variable at all in the first place

  Please post your code for us to help!!

  put a breakpoint and check what value is stored in that session key.

  I tried the same and it worked for me.

  Could you please try 

  sideNav.SelectedNode.Text instead of SideNav.SelectedNode.Value.

  If this doesnt work,

  Try to convert the data from session to Text

  IDLabel.Text = (String)Session["someValue"];

  on the bottom when you're debugging your project, set the breakpoint after when you assign the node.Value to the session variable, there is a window on the bottom of VS called "watch". you can type your variable in there, like

  Session["someValue"]

  and it will tell you what's in there

  In my application (website) sideNav.SelectedNode.Text is the persons Name they are clicking. I need the Value because thats the ID i am trying to get. I tried using (String)Session["someValue"]; and I get the same error :(

  It has the Value I need... in this case "698.23302"

  are you sure its a string format? and not a node or an object? session variables do not always have to be strings or ints.

  I have tried:

  if (Session["someValue"] != null)
  {
      IDLabel.Text = Session["someValue"] as String;
  }

  and I also tried:

  if (Session["someValue"] != null)
  {
      IDLabel.Text = (String)Session["someValue"];
  }

  I also changed the value to text like suggested.

  Session["someValue"] = sideNav.SelectedNode.Text;

  unfortunately still the same error.
