System.Web.UI.WebControls.

I have the following event handler set in a LinkButton control, which I placed into Page_Load.
I want to use the CommandEventHandler(LinkBu
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(LinkBu
lbtn.CommandArgument = i.ToString();
lbtn.Command += new System.Web.UI.WebControls.

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

Bob
CommandEventHandler(LinkBu
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?
