DevExpress: sender.GetSelectedFieldValues not calling my client side call back

Question

I have a GridExtension for MVC that looks like this:

The table it gets data out of looks like this:

Table Name: Category

Id    Name
--------------
1     Foo
2     Bar
3     Gar
4     Har

When I select a row or more from the grid and click the Delete button on the top, I expect that my DeleteSelectedCategories handler should be called, which does happen.

However, in the DeleteSelectedcategories handler, when I call the gvCategories.GetSelectedFieldValues method supplying it the client side call back DeleteCategories, that method does not get called. Instead, I get all my script code shown in a message box like so:

I am using the almost the same code that is shown in this example on the DevExpress documentation website.

Here's my code.

View

<script type = "text/javascript">
//<![CDATA[
    $(document).ready(
        function () {
            WireHandlers();
        }
    );

        function DeleteCategories(selectedCategoriesArray) {

            debugger;

            if (selectedCategoriesArray.length == 0) return;

            for (var i = 0; i < selectedCategoriesArray.length; i++) {
                debugger;
            }
        }

        function DeleteSelectedCategories() {
            // debugger;

            if (gvCategories.GetSelectedRowCount() == 0) return;

            gvCategories.GetSelectedFieldValues('Id', DeleteCategories);
        }

        function WireHandlers() {
            $('#btnDeleteCategory').click(DeleteSelectedCategories);
        }
// ]]>
</script>

@using System.Web.UI.WebControls;
@using System.Data;
@model IEnumerable<GlobalizationUI.BusinessObjects.Category>

@Html.DevExpress().GridView(settings =>
    {
        settings.Name = "gvCategories";

        settings.CallbackRouteValues = new { Controller = "Category", Action = "CategoriesPartial" };

        settings.Width = 1200;

        settings.SettingsPager.Position = PagerPosition.TopAndBottom;
        settings.SettingsPager.FirstPageButton.Visible = true;
        settings.SettingsPager.LastPageButton.Visible = true;
        settings.SettingsPager.PageSizeItemSettings.Visible = true;
        settings.SettingsPager.PageSizeItemSettings.Items = new string[] { "10", "20", "50", "100", "200" };
        settings.SettingsPager.PageSize = 50;

        settings.Settings.ShowFilterRow = true;
        settings.Settings.ShowFilterRowMenu = true;

        settings.CommandColumn.Visible = true;
        settings.CommandColumn.ClearFilterButton.Visible = true;
        settings.CommandColumn.ShowSelectCheckbox = true;

        settings.Settings.ShowHeaderFilterButton = true;

        settings.KeyFieldName = "Id";

        settings.Columns.Add("Name");

        settings.SettingsEditing.AddNewRowRouteValues = new { Controller = "Category", Action = "CreateNew" };
        settings.SettingsEditing.UpdateRowRouteValues = new { Controller = "Category", Action = "Edit" };

        settings.SettingsEditing.Mode = GridViewEditingMode.Inline;

        settings.CommandColumn.Visible = true;
        settings.CommandColumn.NewButton.Visible = true;
        settings.CommandColumn.EditButton.Visible = true;
        settings.CommandColumn.UpdateButton.Visible = true;

    }).Bind(Model).GetHtml()

I am using DevExpress Extensions v12.2.10.0 for ASP.NET MVC 4 on Windows 7 Home Premium.

Answer 1

Put the GridView settings to a separate PartialView (without any other tags).
