[英]Event of RadioButtons
是我的問題
我有幾個RadioButtons 。 如果我在表單創建TextBox上單擊第一個Radiobutton ,如果在第二個上單擊-創建第二個TextBox,並且如果我再次單擊第一個RadioButton ,再單擊一個TextBox ,這可能嗎?
請給我個主意。
而且沒有可見的財產。
在這里動態創建和銷毀控件沒有多大意義。 確保位置,大小和制表符順序正確是一件令人頭疼的事情。 如果您願意,只需使文本框可見:
private void radioButton2_CheckedChanged(object sender, EventArgs e) {
textBox1.Visible = radioButton2.Checked;
}
在設計器中將文本框的Visible屬性設置為False。
嘗試這樣的事情(這只是其中之一):
TextBox t;
private void radio_CheckedChanged(object sender, System.EventArgs e)
{
if (radio.Checked) {
t = new TextBox();
t.Top = radio.Top;
t.Left = radio.Left + radio.Width;
this.Controls.Add(t);
t.Show();
} else {
if (t!=null)t.Dispose();
}
}
請參見僅foreach
和void TextBoxes
。
