WinForm如何控制ShowDialog()的返回值

Question

我做了个有“确定”和“取消”按钮的WinForm
它ShowDialog()后如何做到：
点“确定”返回DialogResult.OK 
点“取消”返回DialogResult.Cancel

Answer 1

点“确定
 this.DialogResult=DialogResult.OK;点“取消”
  this.DialogResult=DialogResult.Cancel

Answer 2

Form做的你自己设置一个变量就行了

Answer 3

button钮有属性 DialogResult
将“确定”钮设为 "OK"
“取消”钮设为"Cancel"就好Form上有 AcceptButton 属性,设为 "确定" 钮
CancelButton 属性,设为"取消"钮

Answer 4

  呵呵。设置dialog的返回的枚举值就可以

Answer 7

你得父界面：
TextDialog textD = new TextDialog();
                while (true)
                { 
                    textD.ShowDialog();
                    if (textD.DialogResult == DialogResult.OK)
                    {
                        if (!string.IsNullOrEmpty(ur—Check))
                        {
                            break;
                        }
                        else
                        {
                            MessageBox.Show("Message.");
                        }
                    }
                    else if(textD.DialogResult == DialogResult.Cancel)
                    {
                        return;
                    }
                }
对话框：
public partial class TextDialog : Form
    {
        public string NodeName
        {
            get
            {
                return textBox1.Text;
            }
            set
            {
                value = textBox1.Text;
            }
        }        public TextDialog()
        {
            InitializeComponent();
            button1.DialogResult = DialogResult.OK;
            button2.DialogResult = DialogResult.Cancel;
        }
    }
