如何在表单加载时阻止检查RadioButton？

Question

我似乎无法阻止我从形式检查的一个单选按钮在我的Group Box:

如设计器所示,那里没有检查Radio Buttons.

下面是这个简单表单的所有代码.没有什么要求在这里或在表单的设计者中检查单选按钮.

问:有没有办法防止在表单加载时检查任何单选按钮？

public ValueTypeSelector() {
  InitializeComponent();
  radioButton1.Checked = false;
  radioButton2.Checked = false;
  radioButton3.Checked = false;
  radioButton4.Checked = false;
  radioButton5.Checked = false;
  radioButton6.Checked = false;
  button1.Enabled = false;
  button1.Click += clickEvent;
  button2.Click += clickEvent;
  radioButton1.Click += clickEvent;
  radioButton2.Click += clickEvent;
  radioButton3.Click += clickEvent;
  radioButton4.Click += clickEvent;
  radioButton5.Click += clickEvent;
  radioButton6.Click += clickEvent;
}

void OnShow(object sender, EventArgs e) {
  foreach (RadioButton rad in Controls) {
    if (rad.Checked) {
      Console.WriteLine("WTF?");
    }
  }
}

void clickEvent(object sender, EventArgs e) {
  RadioButton rad = sender as RadioButton;
  if (rad != null) {
    if (rad.Checked) {
      if (rad == radioButton1) {
        DataType = TableDataType.Boolean; // <= HERE IS THE PROBLEM! FIRES ON FORM LOAD
      } else if (rad == radioButton2) {
        DataType = TableDataType.Character;
      } else if (rad == radioButton3) {
        DataType = TableDataType.DateTime;
      } else if (rad == radioButton4) {
        DataType = TableDataType.Decimal;
      } else if (rad == radioButton5) {
        DataType = TableDataType.Integer;
      } else if (rad == radioButton6) {
        DataType = TableDataType.String;
      } else {
        return;
      }
      button1.Enabled = true;
    }
  } else if (sender == button1) {
    DialogResult = DialogResult.OK;
    Close();
  } else if (sender == button2) {
    DialogResult = DialogResult.Cancel;
    Close();
  }
}

更新:问题是radioButton1在显示表单时检查:

      if (rad == radioButton1) {
        DataType = TableDataType.Boolean; // <= HERE IS THE PROBLEM! FIRES ON FORM LOAD
      } else if (rad == radioButton2) {

Answer 1

确保您的radiobuttons不是第一个tabindex = 0控件.按OK按钮tabindex = 0,然后是radiobuttons.

Answer 2

在设计模式下,您会发现AutoCheck属性设置为true.只需将其变为假.在运行期间手动选择它时,不会检查它.
