Namespace: DevExpress.Web.Mvc

Assembly: DevExpress.Web.Mvc5.v24.2.dll

Declaration

C#

public object CallbackRouteValues { get; set; }

VB.NET

Public Property CallbackRouteValues As Object

Property Value

Type	Description
Object	An object containing the Controller and Action names.

Remarks

The CallbackRouteValues property allows you to pass only simple data (that do not require serialization) to the controller. If you need to send complex data, use one of the following approaches.

1. Use the CallbackRouteValues collection to pass only the information that is required to recreate your complex model instance in the controller action (e.g., row keys or unique identifiers).
2. Convert your complex model class into a simple data type. For instance, use the JSON encoding to pass the model to the controller as a string. Then, in the controller code, decode the passed value to get the model.

Razor

@Html.DevExpress().Calendar(settings => {  
    settings.Name = "Calendar";  
    ...  
    settings.CallbackRouteValues = new  {  
        Controller = "Home",  
        Action = "IndexPartial",  
        myComplexData = Json.Encode(Model.myListData)  
    };  
}).GetHtml()  

C#

public ActionResult IndexPartial(string SelectedIds) {  
    List<int> myData = System.Web.Helpers.Json.Decode<List<int>>(myComplexData);  
    ...  
}
