🔒 Closed how to enabled and disabled button

[m0stwanted143]

If the 3 label amount has no value the button is disabled,
otherwise if any of the 3 label has a value then the button is enabled

ganun padin naman palitan nalang ng Label yung TextBox bali ang gagawin nalang ay

        private void text_changed(object sender, EventArgs e)
        {
            button1.Enabled = GetInt(label1) > 0 || GetInt(label2) > 0 || GetInt(label3) > 0;
        }

        int GetInt(Label text)
        {
            int i = 0;
            int.TryParse(text.Text.Trim(), out i);
            return i;
        }

para sa iba na di alam
1. i ctrl+click yung mga label
2. sa properties iclick events (kidlat na icon)
3. sa events hanapin ang TextChanged
4. itype ang text_changed habang nakaselect yung tatlong label
