System.Web.UI.WebControls.CommandEventHandler(LinkButton_Command)

ASP.NET , C#
I have the following event handler set in a LinkButton control, which I placed into Page_Load.
I want to use the CommandEventHandler(LinkButton_Command) value after PostBack back in
Page_Load to filter a query, which eventually updates the same lbtn property. Needless to say,
I can't seem to be able to get the  CommandEventHandler(LinkButton_Command) value back into Page_Load.
                   
lbtn.CommandArgument = i.ToString();
                   
lbtn.Command += new System.Web.UI.WebControls.CommandEventHandler(LinkButton_Command);

That doesn't make any sense.  The value of what?

CommandEventHandler(LinkButton_Command)
calls the following method      
protected void LinkButton_Command(Object sender, CommandEventArgs e)
and in this method
e.CommandArgument holds the value of  lbtn.CommandArgument = i.ToString()

now here I make a
public string lbtnValue = e.CommandArgument;
but get nothing in lbtnValue in Load_page

I hope it helps

This is the order of things:

1) Click on a LinkButton control
2) An post-back occurs
3) The Page_Load event is fire
4) The LinkButton_Command event is handled

As you can see, you can't get the value from Page_Load, because it hasn't happened yet.

so,
what is your suggestion to solve this problem.
I tried to set the value into a session var, label, text in the method they don't show up in Page_Load only after the second post-back.
Generally, how do get the LinkButton_Command event value back in one trip if I dynamically create a control and place it into Page_Load?

Can you describe the bigger picture and what you need to accomplish, so that I could recommend the "best" course of action, please?
