DevExpress WinForms Subscription擁有180+組件和UI庫，能為Windows Forms平臺創建具有影響力的業務解決方案。DevExpress WinForms能完美構建流暢、美觀且易于使用的應用程序，無論是Office風格的界面，還是分析處理大批量的業務數據，它都能輕松勝任！

類替代標準的組件，它提供了創建包含控件和組件的獨立模塊的功能，這些模塊可以在整個應用程序中重復使用。

C#

//Create an XtraUserControl that represents a login form
public class LoginUserControl : XtraUserControl {
public LoginUserControl() {
LayoutControl lc = new LayoutControl();
lc.Dock = DockStyle.Fill;
TextEdit teLogin = new TextEdit();
TextEdit tePassword = new TextEdit();
CheckEdit ceKeep = new CheckEdit() { Text = "Keep me signed in" };
lc.AddItem(String.Empty, teLogin).TextVisible = false;
lc.AddItem(String.Empty, tePassword).TextVisible = false;
lc.AddItem(String.Empty, ceKeep);
this.Controls.Add(lc);
this.Dock = DockStyle.Fill;
}
}

//Show an XtraUserControl-based login form inside a dialog
private void simpleButton1_Click(object sender, EventArgs e) {
LoginUserControl myControl = new LoginUserControl();
DevExpress.XtraEditors.XtraDialog.Show(myControl, "Sign in", MessageBoxButtons.OKCancel);
}

VB.NET

'create an XtraUserControl that represents a login form
Public Class LoginUserControl
Inherits XtraUserControl

Public Sub New()
Dim lc As New LayoutControl()
lc.Dock = DockStyle.Fill
Dim teLogin As New TextEdit()
Dim tePassword As New TextEdit()
Dim ceKeep As New CheckEdit() With {.Text = "Keep me signed in"}
lc.AddItem(String.Empty, teLogin).TextVisible = False
lc.AddItem(String.Empty, tePassword).TextVisible = False
lc.AddItem(String.Empty, ceKeep)
Me.Controls.Add(lc)
Me.Dock = DockStyle.Fill
End Sub
End Class

'show an XtraUserControl-based login form inside a dialog
Private Sub simpleButton1_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim myControl As New LoginUserControl()
DevExpress.XtraEditors.XtraDialog.Show(myControl, "Sign in", MessageBoxButtons.OKCancel)
End Sub

要在設計時添加XtraUserControls，請右鍵單擊您的項目，然后選擇 "Add DevExpress Item" 選項，這將調用，該庫允許您添加空白XtraUserControls和DevExpress表單以及基于模板的表單。

與標準WinForms UserControl相比，XtraUserControl具有以下優點：

• 最終用戶可以在懸停時滾動XtraUserControl內容，而無需首先關注它；
• 與布局和數據布局控件組件通信來傳遞正確的控件大小；
• 允許您直接從承載此容器的表單（可視繼承）中為XtraUserControl（或其子）內部的控件使用智能標記和Designer對話框；
• 支持DevExpress皮膚，并確保整個應用程序的外觀一致性。
