DevExpress WinForms Subscription擁有180+組件和UI庫，能為Windows Forms平臺(tái)創(chuàng)建具有影響力的業(yè)務(wù)解決方案。DevExpress WinForms能完美構(gòu)建流暢、美觀且易于使用的應(yīng)用程序，無論是Office風(fēng)格的界面，還是分析處理大批量的業(yè)務(wù)數(shù)據(jù)，它都能輕松勝任！

類替代標(biāo)準(zhǔn)的組件，它提供了創(chuàng)建包含控件和組件的獨(dú)立模塊的功能，這些模塊可以在整個(gè)應(yīng)用程序中重復(fù)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(shè)計(jì)時(shí)添加XtraUserControls，請(qǐng)右鍵單擊您的項(xiàng)目，然后選擇 "Add DevExpress Item" 選項(xiàng)，這將調(diào)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(biāo)準(zhǔn)WinForms UserControl相比，XtraUserControl具有以下優(yōu)點(diǎn)：

• 最終用戶可以在懸停時(shí)滾動(dòng)XtraUserControl內(nèi)容，而無需首先關(guān)注它；
• 與布局和數(shù)據(jù)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(nèi)部的控件使用智能標(biāo)記和Designer對(duì)話框；
• 支持DevExpress皮膚，并確保整個(gè)應(yīng)用程序的外觀一致性。
