Description
I want to populate a Telerik UI for ASP.NET MVC DropDownList editor of a Form with the Enum values and bind them to the model. How can I do this?
Solution
To achieve the desired results:
Use the Html.GetEnumSelectList
() to get theSelectListof the available options.Use the
BindTo()configuration of the DropDownList to bind to the returnedSelectList.
Refer to this REPL example for a runnable demo of the snippet below:
@using System.ComponentModel
@functions{
public enum Difficulty { Easy, Normal, Hard }
public class MyModel
{
public string Name {get;set;}
public Difficulty SelectedOption {get; set;}
}
}
@{
var modelData = new MyModel(){Name = "Player 1", SelectedOption = Difficulty.Normal};
}
@(Html.Kendo().Form<MyModel>()
.Name("exampleForm")
.FormData(modelData)
.HtmlAttributes(new { action = "Items", method = "POST" })
.Validatable(v =>
{
v.ValidateOnBlur(true);
v.ValidationSummary(vs => vs.Enable(true));
})
.Items(items =>
{
items.AddGroup()
.Label("Choose Game settings")
.Items(i =>
{
i.Add()
.Field(f => f.Name)
.Label(l => l.Text("Player Name:"));
i.Add()
.Field(f => f.SelectedOption)
.Label(l => l.Text("Difficulty:"))
.Editor(e =>
{
e.DropDownList()
.DataTextField("Text")
.DataValueField("Value")
.Height(520)
.BindTo(Html.GetEnumSelectList<Difficulty>());
});
});
})
)
