500pts: Getting the ID from sender in event?

Hi there,

Can anybody help?

I have an event (click) that i have assigned to lots of Checkboxes.

And in that click evetn... i wil to add the name to of the item that was Checked or unchecked to a listbox

But how do i know which control was clicked as they all share the same event... i thought it might be the sender (see below)

            private void uxFieldsCheckBox_CheckedChanged(object sender, System.EventArgs e)
            {
                  ListBox test = new(ListBox)sender;
                  
                  // uxOrderListBox.Items.Add(  
            }

Thanks in advance ...

Ian

Well, you're close, but is the sender is a CheckBox, it should be:

          private void uxFieldsCheckBox_CheckedChanged(object sender, System.EventArgs e)
          {
               CheckBox test = sender as CheckBox;
               if (test != null)
               { // is is indeed a CheckBox
                 
                 uxOrderListBox.Items.Add(test.Text);
               }
          }
