Question

I am still trying to learn about c#, my question is how would I pass a variable from Item1_Click to Item2_Click, is this the same thing as passing them between methods or is this different because they are event handlers?

public partial class Events : System.Web.UI.UserControl
{
     protected void Item1_Click(object sender, EventArgs e)
    {

          //code

    }

    protected void Item2_Click(object sender, EventArgs e)
    {
          //code
    }
}

They are still regular methods, so you’re still able to call them the same way you normally would.

 protected void Item1_Click(object sender, EventArgs e)
 {
    // Call the event handler for Item2, passing the arguments
    // Item1 received
    Item2_Click(sender, e);
 }

 protected void Item2_Click(object sender, EventArgs e)
 {
     // Make it happen.
 }

If you want to re-use Item1_Click just bind the click event of the other object to Item1_Click as well.
