XtraDialog
XtraDialog是一個替代標(biāo)準(zhǔn)對話框的消息框。與標(biāo)準(zhǔn)對話框一樣，它允許您在其客戶端區(qū)域顯示控件(例如，UserControl)和按鈕集，然而，與標(biāo)準(zhǔn)對話框不同的是，它支持DevExpress皮膚來應(yīng)用一致的外觀。例如，下圖顯示了一個與應(yīng)用程序主題不匹配的標(biāo)準(zhǔn)對話框。
第二幅圖顯示了使用XtraDialog的同一個應(yīng)用程序。
要顯示對話框，請調(diào)用靜態(tài)XtraDialog.Show方法。此方法的參數(shù)允許您指定在其客戶端區(qū)域顯示哪個控件，指定對話框的標(biāo)題，并添加預(yù)定義的按鈕：
下面的代碼調(diào)用一個XtraDialog，顯示一個帶有自定義控件的UserControl(兩個TextEdit控件和一個CheckEdit控件)，以及OK和Cancel按鈕：
