[Solved] Post multiple values from EditorTemplate

[JULIA]

Hello,

i have the following EditorTemplate.

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<TumourResectionTypeViewModel>" %>

<%= Html.DropDownList( null, new SelectList( ( IEnumerable )ViewData["tumourResectionTypes"],
                                            "TumourResectionTypeId", "TypeName" ), new { style = "width: 50%;" } )%>

<%= Html.LabelFor( m => m.IsCured ) %>
<%= Html.CheckBoxFor( m => m.IsCured )  %>

<script type="text/javascript">
    var $dropdown = $('#TumourResectionType');
    $('<option/>', { text: '...', value: "" }).prependTo($dropdown);
    var $tr = $dropdown.closest('tr:has(form)');
    var grid = $tr.closest('.t-grid').data('tGrid');
    var dataItem = grid.dataItem($tr);
    $dropdown.val(dataItem.TumourResectionType ? dataItem.TumourResectionType.TumourResectionTypeId : "");

    var c = $tr.find("input[type=checkbox]:first");
    var l = $tr.find("label:first");
    if (dataItem.TumourResectionType.IsCured) {
        c.attr("checked", "checked");
    }
    else {
        c.removeAttr("checked");
    }

    $dropdown.change(function () {
        if ($(this).val() == 1) {
            l.show();
            c.show();
        }
        else {
            l.hide();
            c.hide();
        }
    }).change();
</script>

The bool value for IsCured will never post. How can i achieve this goal?

Mit Update/Insert Action:

public ActionResult _Update( GridCommand command, int tumourResectionType, bool isCured = false, int id = 0 )

IsCured is always false.

Hello Timo,

The rendered checkbox sends its value to the server, but the IValueProvider does not catch it from the posted data. As you probably know the name property of the rendered checkbox (and all other HTML elements which has name property) should have the same value as the expected parameter of the Action. In other words if you render checkbox with name="IsCured", you need to have same parameter in the Action method:
public ActionResult ActionMethod(bool IsCured). In your case the parameter is named "isCured".

I will open a ticket with a sample project.

Hello Timo,

Here is a quote of the answer which I send you in the support thread:

Thank you for contacting us.

ASP. NET MVC EditorFor HTML helper uses passed Lambda expression to get the property of the model for which it is created. In other words if you uses Html.CheckBoxFor(m => m.IsCured) the rendered inpu will have name property with "Employee.IsCured". Hence on the server you need to expect Employee object, not just IsCured parameter. In you case IValueProvider could not update Employee object (defined by Linq2SQL), that is why I am creating fake EmployeeFake object just for the test. Check the attached project for reference.

If you decide not to use CheckBoxFor (or other EditorFor extensions) method you can use separate parameters which represent Employee properties. Here is a code snippets showing what I mean:

[ASCX]:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Employee>" %>

<%= Html.CheckBox("isCured", Model.IsCured) %>

        [GridAction]
        public ActionResult UpdateOrder(int id, bool isCured)
        {
...

Let me know if this helps.

All the best,
