The SetContent method allows you to define the content of DevExpress MVC extensions. This example demonstrates how to use these method overloads to define RoundPanel content in the following ways:
- Call the SetContent(String content) method overload to specify the content as a string. This overload is intended for scenarios where it is necessary to render simple HTML content (specified directly as a parameter).
settings.SetContent(@"<table border=\"1\"><tr><td>RoundPanel Content Here</td></tr></table>"); - Call the SetContent(Action contentMethod) method overload to add a DevExpress MVC Extension in the panel content.
settings.SetContent(() => { Html.DevExpress().Label(lbl => { lbl.Name = "lbl"; lbl.Text = "DevExpress Label - Some Text"; }).Render(); }); - Call the ViewContext.Writer.Write method to combine different syntax constructions (raw HTML tags, action methods, built-in HtmlHelper methods, DevExpress MVC Extensions) into a text stream and pass it to the SetContent(String content) method overload.
settings.SetContent(() => { //Raw HTML ViewContext.Writer.Write("<table border=\"1\"><tr><td>Content From Raw <b>HTML</b> Table Here...</td></tr></table>"); ViewContext.Writer.Write("<br/>"); //Action Method Html.RenderAction("SeparateAction"); ViewContext.Writer.Write("<br/>"); ViewContext.Writer.Write("<br/>"); //Partial View with Html.BeginForm Html.RenderPartial("SeparatePartialView"); ViewContext.Writer.Write("<br/>"); ViewContext.Writer.Write("<br/>"); //Html Helper ViewContext.Writer.Write(Html.TextBox("txtName").ToHtmlString()); ViewContext.Writer.Write("<br/>"); ViewContext.Writer.Write("<br/>"); //Conditional ViewContext.Writer.Write("Content From Conditional Rendering Block:"); ViewContext.Writer.Write("<br/>"); bool condition = DateTime.Now.Year == 2014; if(condition) { ViewContext.Writer.Write("<b>Condition Passed</b>"); } else { ViewContext.Writer.Write("<b>Condition Failed</b>"); } ViewContext.Writer.Write("<br/>"); ViewContext.Writer.Write("<br/>"); //DevExpress MVC Extensions Html.DevExpress().Label(lbl => { lbl.Name = "lbl"; lbl.Text = "Content From DevExpress Label Here..."; }).Render(); });
You can use these approaches for every DevExpress MVC Extension that suppors the SetContent or SetNestedContent method.
It is also possible to handle Set{ElementName}TemplateContent methods to define template content.
