in C#, Append selection multiple times from 2 ComboBoxes into a TextBox using a button

I am trying to append selections from 2 ComboBoxes into a TextBox with a click of a button and I am not sure how to do this. I can do it once with code like this:

 private void BTN_APPEND_Click(object sender, EventArgs e)
    {
        TB_CONNECTORS.Text = CB_PORT_NUMBER.Text + " " + CB_CONNECTOR.Text;
    }

And this will result in Append with the click of a button

but the question is, how can I append to this one more time?

Solution

  • Did you try this :

     if(!TB_CONNECTORS.Text == "")
 {
 TB_CONNECTORS.Text = TB_CONNECTORS.Text + " & " + CB_PORT_NUMBER.Text + " " + CB_CONNECTOR.Text;
 }
 else
 {
 TB_CONNECTORS.Text = CB_PORT_NUMBER.Text + " " + CB_CONNECTOR.Text;
 }

    This will result in the new value achieved from the 2 comboboxes keeping the existing text of the textbox
