I am trying to Session over my categoryName over to the next page when clicked on the LinkButton. However, when i debug my codes, it didnt go inside the if statement and skipped it. I do not know what exactly the problem is. Have i gone wrong anywhere?

Here is my .cs code for the first page:

C#

categoryName.Text = Session["categoryName "].ToString();
        Response.Redirect("Category2.aspx");

Here is my .cs code for the second page (I place this code in Page_Load):

C#

protected void Page_Load(object sender, EventArgs e)
    {
        if (Session["categoryName "] != null)
        {
            categoryName .Text = Session["categoryName "].ToString();
        }
    }

Solution 1

You never set the session value. To set a session value:

C#

Session["name"] = value;

But my session value is I get from database. So if i set a value to it, am i hard coding it?

If you get a value from database you still have to set the session variable:
Session["categoryName"] = valueFromDatabase;

Solution 2

Declare a variable.

string CategoryName=//something. get from database;

Before clicking on linkbutton or in link button click
set

C#

Session["categoryName"]=CategoryName;
