イベント有効になっている？
Form1_ResizeEndのメソッドに処理が入っているかそこから確認
int leftEdge, rightEdge,topEdge ,bottomEdge;
public Form1()
{
InitializeComponent();
this.ResizeBegin += Form1_ResizeBegin;
this.ResizeEnd += Form1_ResizeEnd;
}
private void Form1_ResizeBegin(object sender, EventArgs e)
{
this.Text = "start";
leftEdge = this.Left;
rightEdge = this.Right;
topEdge = this.Top;
bottomEdge = this.Bottom;
}
private void Form1_ResizeEnd(object sender, EventArgs e)
{
this.Text = String.Format("{0}:{1}", (rightEdge < this.Right), (topEdge > this.Top));
if ((rightEdge < this.Right) && (topEdge > this.Top))
{
this.Text = "OK";
}
}
これで動いた
