Validation is not working on grid dropdown column

[Than Htike Aung]

@(Html.EJ().Grid<object>("FlatGrid")

    .Datasource(ds => ds.URL("api/List").BatchURL("api/Update").Adaptor(AdaptorType.UrlAdaptor))

    .AllowPaging()

    .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.Batch).ShowConfirmDialog(); })

    .ToolbarSettings(toolbar =>

    {

        toolbar.ShowToolbar().ToolbarItems(items =>

        {

            items.AddTool(ToolBarItems.Add);

            items.AddTool(ToolBarItems.Edit);

            items.AddTool(ToolBarItems.Delete);

            items.AddTool(ToolBarItems.Update);

            items.AddTool(ToolBarItems.Cancel);

        });

    })

    .Columns(col =>

    {

        col.Field("UserName").HeaderText("User Name").EditType(EditingType.String).Add();

        col.Field("UserEmail").HeaderText("User Email").EditType(EditingType.String).Add();

        col.Field("Role").HeaderText("Role").EditType(EditingType.Dropdown).ValidationRules(v => v.AddRule("required", true).AddRule("minlength", 3)).DataSource(ViewBag.ds).Add();

    }))

Role column still allows empty selection, even with validation. Datasource came from backend with list of string.

How can I solve this issue?

Thanks

Thanks for reply Farveen sulthana T.

I found out that "jquery.validate.min.js" is not included in render list even though there is such file already existed in project list.

After I included that file in _Layout, it works fine and problem is solved.

FYI, I used Syncfusion project template to create project.

Best regards,

Aung
