Question

请问C#窗口内，tabControl1里面的3个datagridview控件如何跟窗口同步缩放大小？
在窗口属性Anchor或窗口事件Resize写下面代码都无法调整，请问该怎么写？谢谢！

this.dataGridView1.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom)
            | System.Windows.Forms.AnchorStyles.Left)
            | System.Windows.Forms.AnchorStyles.Right)));

              this.dataGridView2.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom) 
            | System.Windows.Forms.AnchorStyles.Left) 
            | System.Windows.Forms.AnchorStyles.Right)));

            this.dataGridView3.Anchor = ((System.Windows.Forms.AnchorStyles)(((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Left)
            | System.Windows.Forms.AnchorStyles.Right)));

想达到3个datagridview控件的缩放效果是如下面图片那样，最左边的datagridview右边缩放是在中间，另外两个datagridview最左边缩放都在中间。

Answer 1

panel1.Dock = Left;
panel1 加1个dataGridView，  Dock = Fill;

panel2.Dock = Right;
panel2 加2个dataGridView，  Dock = Top 和 Bottom

 private void Form2_SizeChanged(object sender, EventArgs e)
{
  panel1.Width = this.Width / 2;
  panel2.Width = this.Width / 2;
  dataGridView2.Height = (int)(panel2.Height * 0.4);
  dataGridView3.Height = (int)(panel2.Height * 0.6);
}
