Validation is not working on grid dropdown column

    .Datasource(ds => ds.URL("api/List").BatchURL("api/Update").Adaptor(AdaptorType.UrlAdaptor))
    .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.Batch).ShowConfirmDialog(); })
    .ToolbarSettings(toolbar =>
        toolbar.ShowToolbar().ToolbarItems(items =>
    .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?

Hi Than, 
Thanks for contacting Syncfusion Support. 
We have checked your query and prepared sample with dropdown column for the Grid. But we are unable to reproduce the issue “validation is not working for the Grid dropdown column”. Please make ensure that you have added the “jquery.validate.min.js” file in your script section. Please refer to the sample and screenshot:-

 We need some additional information to find the cause of the issue. Could you please share us the following details given below. 
1. Grid code example ( both in server side and client side).  
2. Share your Layout.cshtml page. Also share screenshot as like above.

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,
