Can't Find Error In Validation

OK SO this is a little hard to actually explain but- I have a multiselect with a datasource and validation rules, not unlike this demo here. For some reason, it's failing validation even though it has a value. What is going wrong/how can I fix it/what further details do I need to provide?

Thank you, I apologize for the poor explanation.

Using Editor As Grid Column's Custom Editor Not Saving

This dojo accurately reproduces my problem: https://dojo.telerik.com/EKEGAqoq

If you update the ProductName will just plain text (no rich-text editor options), the grid updates fine, but as soon as you use one of the rich-text features (bold, italics, bullet, numbering, etc.), the grid does not update and the model is marked as "dirty".

Add fonts to fontFamily toolbar menu

The standard fontFamily toolbar menu lists the following fonts: "Arial", "Courier New", "Georgia", "Times New Roman", "Trebuchet MS", "Verdana"

I'd like to add additional ones to the list but haven't been able to figure out how. There appears to be support for customizing the list by setting a fontFamilies property somewhere, but I haven't been able to figure out where to do this or how to get a reference to the drop down list.

Thanks

MVC Treeview with checkboxes on Custom Edit Popup from Grid

I have Index.shtml with Grid control:

@(Html.Kendo()

.Grid<EditingWithServerValidation.Models.Product>()

.Name("Grid")

.Columns(columns =>

{

columns.Bound(p => p.Id);

columns.Bound(p => p.Name);

columns.Command(command => command.Edit()).Width(100);

})

.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("Details"))

.DataSource(dataSource => dataSource

.Ajax()

.Batch(false)

.ServerOperation(false)

.Model(model => model.Id(p => p.Id))

.Read("_Read", "Home")

.Update("_Update", "Home")

)

Controller have _Read method

public ActionResult _Read([DataSourceRequest] DataSourceRequest request)

{

List<Product> MyProduct = GetProductsList();

return Json(MyProduct.ToDataSourceResult(request));

}

public ActionResult Index([DataSourceRequest] DataSourceRequest request)

{

ViewBag.AreaOfLaw = GetAreaLaw();

return View();

}

private List<Product> GetProductsList()

{

List<Product> MyProd = new List<Product>();

for (int i = 1; i < 10; i++)

{

Product p = new Product();

p.Id = i;

p.Name = "Product #" + i.ToString();

MyProd.Add(p);

}

return MyProd;

}

private List<TreeViewItemModel> GetAreaLaw()

{

List<TreeViewItemModel> TVList = new List<TreeViewItemModel>();

TreeViewItemModel AL = new TreeViewItemModel();

AL.Id = "1";

AL.Text = "ROOT-1";

AL.HasChildren = true;

AL.Expanded = true;

TreeViewItemModel SubAL = new TreeViewItemModel();

SubAL.Id = "3";

SubAL.Text = "Sub-1-1";

AL.Items.Add(SubAL);

TVList.Add(AL);

AL = new TreeViewItemModel();

AL.Id = "2";

AL.Text = "ROOT-2";

AL.HasChildren = true;

AL.Expanded = true;

SubAL = new TreeViewItemModel();

SubAL.Id = "4";

SubAL.Text = "Sub-2-1";

AL.Items.Add(SubAL);

SubAL = new TreeViewItemModel();

SubAL.Id = "5";

SubAL.Text = "Sub-2-2";

AL.Items.Add(SubAL);

TVList.Add(AL);

return TVList;

}

And Model describe Product:

public class Product

{

public int Id { get; set; }

[Required]

public string Name { get; set; }

}

Details.shtml Custom PopUP template as simple as possible (I remove from this template all other markup except treeview )

<div id="tv" style="overflow:scroll; height:200px;">

@(Html.Kendo().TreeView()

.Name("treeview")

.Checkboxes(true)

.BindTo((IEnumerable<TreeViewItemModel>)ViewBag.AreaOfLaw)

)

</div>

When I run it - I got the grid , Edit click Open Popup with Treeview , but Checkboxes behavior is weird - click on any one checkbox Select All or Clead All checkboxes on the screen

When I move Treeview from Popup template on Index.shtml page it's working as expected. Please advise.

KendoEditor Changes in Grid's Popup Editor Not Saving

Currently my grid implementation is using the popup editor and a kendo template to render the markup. I was able to use the KendoEditor widget (rich-text editor) inside the popup by calling it inside the grid's Edit event. Making normal text changes does not pose a problem, but when I make changes using the KendoEditor features (bold, italics, bullets, etc.) the grid does not save, and the grid field in question (HeadLine) is marked as dirty. How do I get around this? Thank you.

Markup:

<body>

<div id="grid"></div>

<script id="popup-editor" type="text/x-kendo-template">

<form class="k-form k-form-vertical" id="headline-popup">

<div>

<label class="k-edit-label" for="Headline">News Headline</label>

<div class="k-edit-field">

<textarea id="headline-test" name="HeadLine" rows="4">#: HeadLine#</textarea>

</div>

</form>

</script>

</body>

JavaScript:

$("#grid").kendoGrid({

dataSource: data,

columns: [

{ field: "Headline", title: "News Headline", width: "5%", headerAttributes: { "class": "font-weight-bold" } },

{ command: ["edit"], width: "10%" }

],

editable: {

mode: "popup",

template: kendo.template($("#popup-editor").html()),

},

edit: function (e) {

$("#headline-test").kendoEditor({});

},

});

popups offset incorrect when body margin set to auto

On my page I have my body element centered in the browser window with body { margin: 0 auto; }. When I trigger any popup, such as an autocomplete list or kendo window, the popup wrapper is positioned too far to the right.

For example, if the body's left offset is 400px, then that's how far off to the right the popup window is misplaced. If I shrink my browser window so it just fits the body (making the body margin effectively 0) then the popup is positioned correctly.

So, it appears that having an auto margin on a parent element is not being handled properly when calculating the position of the popup container.
