groupbox焦点问题

[buyaowen]

我在一个groupbox里面放了两个button，请问有没有属性让一个button的焦点失去后焦点落到另一个上，我现在把两个button的tabstop都设成了true，但是不好使。是不是微软就是设计成一个groupbox里面的组件只能获得一次焦点啊？

試試用SetFouce行不行?

tabIndex你怎么设的?
两个按钮的数字相连试下

这是代码：
还有那个SetFouce是哪里的？没找到这个属性啊 //
// groupBox1
//
this.groupBox1.Controls.Add(this.rdbAfter);
this.groupBox1.Controls.Add(this.rdbBefore);
this.groupBox1.Location = new System.Drawing.Point(40, 96);
this.groupBox1.Name = "groupBox1";
this.groupBox1.Size = new System.Drawing.Size(112, 88);
this.groupBox1.TabIndex = 906;
this.groupBox1.TabStop = false;
//
// rdbBefore
//
this.rdbBefore.Checked = true;
this.rdbBefore.Font = new System.Drawing.Font("ＭＳ ゴシック", 16F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((System.Byte)(128)));
this.rdbBefore.ForeColor = System.Drawing.Color.Black;
this.rdbBefore.Location = new System.Drawing.Point(8, 15);
this.rdbBefore.Name = "rdbBefore";
this.rdbBefore.Size = new System.Drawing.Size(104, 32);
this.rdbBefore.TabIndex = 1;
this.rdbBefore.TabStop = true;
this.rdbBefore.Text = "前";
//
// rdbAfter
//
this.rdbAfter.Font = new System.Drawing.Font("ＭＳ ゴシック", 16F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((System.Byte)(128)));
this.rdbAfter.ForeColor = System.Drawing.Color.Black;
this.rdbAfter.Location = new System.Drawing.Point(8, 56);
this.rdbAfter.Name = "rdbAfter";
this.rdbAfter.TabIndex = 10;
this.rdbAfter.TabStop = true;
this.rdbAfter.Text = "后";
