参考代码如下：

VB.NET

@Html.DevExpress().CallbackPanel( _
Sub(settings)
settings.Name = "callbackPanel"
settings.CallbackRouteValues = New With {Key .Controller = "Home", Key .Action = "CallbackPanelPartial"}
settings.Width = System.Web.UI.WebControls.Unit.Percentage(100)
settings.Height = 300
settings.SetContent( _
Sub()
Html.RenderPartial("ReportViewerPartial")
End Sub)

End Sub).GetHtml()

C#

@Html.DevExpress().CallbackPanel(
settings => {
settings.Name = "callbackPanel";
settings.CallbackRouteValues = new { Controller = "Home", Action = "CallbackPanelPartial" };
settings.Width = System.Web.UI.WebControls.Unit.Percentage(100);
settings.Height = 300;
settings.SetContent(() => {
@Html.RenderPartial("ReportViewerPartial");
});
}).GetHtml()
