右下のレイアウトプロパティ

Question

Windows CE用の独自のカスタムプログレスバーコントロールを作成しています.Net 2.0 C＃アプリケーション。以下は、不足している細かい唯一のものを動作するコードである私は、右から左に進行状況を表示したいされて誰もが進捗矩形RTLプロパティに上記のコードで

を取得するには、このコードを変更するには私を助けることができますこのようにして作成：

float percent = (float)(val - min)/(float)(max - min); 
Rectangle rect = this.ClientRectangle; 
rect.Width = (int)((float)rect.Width * percent); 

あなたは単にコントロールの右側から進行矩形を埋めるために、コードの下にコードを変更することができます。

float percent = (float)(val - min)/(float)(max - min); 
Rectangle rect = this.ClientRectangle; 
var w = (int)((float)rect.Width * percent); 
rect.X = rect.Width - w; 
rect.Width = w;
