好吧,这让我很烦,我就是不知道出了什么问题......
我做了两个表格。第一种形式只有一个简单的按钮,它以对话框的形式打开另一种形式,如下所示:
using (Form2 f = new Form2())
{
if (f.ShowDialog() != DialogResult.OK)
MessageBox.Show("Not OK");
else
MessageBox.Show("OK");
}
第二个,即Form2
,上面有两个按钮。我所做的只是将表单 AcceptButton 设置为一个,将 CancelButton 设置为另一个。在我看来,这就是完成这项工作所需要的一切。但是当我运行它时,我单击打开 Form2 的按钮。我现在可以单击设置为 CancelButton 的一组,然后出现“Not OK”消息框。但是当我单击一组作为 AcceptButton 时,什么也没有发生?Form2 的 InitializeComponent 代码如下所示:
private void InitializeComponent()
{
this.button1 = new System.Windows.Forms.Button();
this.button2 = new System.Windows.Forms.Button();
this.SuspendLayout();
//
// button1
//
this.button1.Location = new System.Drawing.Point(211, 13);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(75, 23);
this.button1.TabIndex = 0;
this.button1.Text = "button1";
this.button1.UseVisualStyleBackColor = true;
//
// button2
//
this.button2.DialogResult = System.Windows.Forms.DialogResult.Cancel;
this.button2.Location = new System.Drawing.Point(130, 13);
this.button2.Name = "button2";
this.button2.Size = new System.Drawing.Size(75, 23);
this.button2.TabIndex = 1;
this.button2.Text = "button2";
this.button2.UseVisualStyleBackColor = true;
//
// Form2
//
this.AcceptButton = this.button1;
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.CancelButton = this.button2;
this.ClientSize = new System.Drawing.Size(298, 59);
this.Controls.Add(this.button2);
this.Controls.Add(this.button1);
this.Name = "Form2";
this.Text = "Form2";
this.Load += new System.EventHandler(this.Form2_Load);
this.ResumeLayout(false);
}
除了添加这两个按钮并设置 AcceptButton 和 CancelButton 之外,我什么也没做。为什么它不起作用?
