一组控件和组件允许开发人员构建HTML格式的UI,并使用CSS样式自定义UI元素的外观设置、大小、填充和布局选项,不再需要处理自定义绘制事件或更改大量属性来修改控件以匹配UI规范,可以使用HTML和CSS标记的知识为桌面应用程序构建布局。
主要功能包括:
HTML-CSS标记
支持HTML和CSS的控件和组件从模板呈现它们的UI,控件模板的HTML标记指定控件的内容(UI元素),而模板的CSS代码指定应用于UI元素的样式、显示和布局设置。
使用控件的HtmlTemplate属性来指定模板,在设计时,开发人员可以在HTML Template Editor(HTML模板编辑器)中创建模板。
该编辑器支持语法高亮显示、智能感知(一种代码完成辅助工具)和预览面板,预览面板允许开发人员检查可视元素——将鼠标悬停在元素上时定位的HTML标记。
示例
下面的示例演示了一个HtmlContentControl从指定的HTML-CSS模板呈现一个UI,该控件被绑定到Employee对象的列表。模板的HTML代码包含数据绑定表达式,用于显示来自数据源的值。
C#
public class Employee {
public string DisplayName { get; set; }
public string FullName { get; set; }
public SvgImage Photo { get; set; }
}
//...
Employee emp = new Employee();
emp.DisplayName = "Leah Test Coordinator";
emp.FullName = "Leah Simpson";
SvgImageCollection imageCollection = new SvgImageCollection();
imageCollection.Add("photo", "image://svgimages/icon builder/business_businesswoman.svg");
emp.Photo = imageCollection["photo"];
List list = new List();
list.Add(emp);
htmlContentControl1.DataContext = list;
//...
void OnButtonClick(object sender, DxHtmlElementMouseEventArgs args) {
if(args.ElementId == "uploadBtn") {
//...
}
if (args.ElementId == "removeBtn") {
//...
}
XtraMessageBox.Show("Button " + args.ElementId + " clicked");
}
VB.NET
Public Class Employee
Public Property DisplayName() As String
Public Property FullName() As String
Public Property Photo() As SvgImage
End Class
'...
Dim emp As Employee = New Employee()
emp.DisplayName = "Leah Test Coordinator"
emp.FullName = "Leah Simpson"
Dim imageCollection As SvgImageCollection = New SvgImageCollection()
imageCollection.Add("photo", "image://svgimages/icon builder/business_businesswoman.svg")
emp.Photo = imageCollection("photo")
Dim list As New List(Of Employee)()
list.Add(emp)
htmlContentControl1.DataContext = list
'...
Private Sub OnButtonClick(ByVal sender As Object, ByVal args As DxHtmlElementMouseEventArgs)
If args.ElementId = "uploadBtn" Then

End If
If args.ElementId = "removeBtn" Then

XtraMessageBox.Show("Button " & args.ElementId & " clicked")
End Sub
