动态创建不同的会话变量

Question

I was wondering if it was possible to dynamically create different session variables with different names based on a variable?

I attempted to accomplish this way but does not seem to like my variable

protected void myGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    LinkButton lb = (LinkButton)e.Row.FindControl("MyLinkButton");
    Label options = (Label)e.Row.FindControl("MyLabel");
    if (e.Row.RowType == DataControlRowType.DataRoow)
    {
    Session[lb] = options;  
//I was trying to use this to create Session Variables with Different Names Dynamically
    }

}

So my end result I would have the following sessions with out having to manually create all of them.

Session["Value"] = "MyOption"
Session["Value1"] = "MyOption1"
Session["Value2"] = "MyOption2"
Session["Value3"] = "MyOption3"

Answer 1

You're doing it backward. Since you are in the RowDataBound Event, clearly you are data binding. So save the data in Session["DataSource"] or something like that, instead of re-creating the data set when you bind it row by row.

I suggest ViewState because it's only valid for that page. If you don't plan on using the data outside of that page, there's no reason to add it to Session.

What are you using the Session data for?

You can create a list of sections. For exaple:

List<string> sections=GetSectionsList();

The for each item in your list create a Session variable and populate with the status, something like this:

foreach(string section in sections)
{
   Session[section] = GetSectionStatus(section);
}

Then onload of each section check for the sections session value and act accordingly. But a piece of advice there use session for this situation only if the sections are considerably less in number say 2 to 5, else a db call on load of each section would be better.
