[Solved] Server binding : how to keep my value an int ?

[Thomas B]

Hello

I am new to MVC, and I am trying to use the DropDownList control.
I copy/pasted the example code, like such :

 ViewData["jeux"] = new SelectList(_entities.jeux.ToList(), "jeu_id", "jeu_nom");

<%= Html.Telerik().DropDownList()
                        .Name("jeux")
                        .BindTo((IEnumerable<SelectListItem>)ViewData["jeux"])
                    %>

But on the POST, the returned value is a string, though it should be an int, so the ModelState is not valid.
And I have no idea how to return an int, or convert it to int before validating the ModelState, or whatever.

Thanks for your help

Hello Broust Thomas,

The posted values to the server is expected to be string. The ASP.NET MVC ModelBinder should get posted value and convert it to the type of the Action parameter. You can check Server validation example locally in order to find out how the ProductDto is bound by ASP.NET MVC framework.

Nevertheless to avoid any misunderstandings I will suggest you implement the same functionality with the Html.DropDownList extension component
