Hi Kendo Team,
We are using kendo MVC textboxes, dropdowns, Grids, etc controls on our application pages.
We have used the @Html.Kendo().DeferredScripts(true) on the pages. However, we are seeing that this is taking close to 1 sec in the browser. All our APIs are returning data in less than 500 ms, but this causes the page to be rendered in close to 2 sec, when it could be faster.
Please advise if there is a way to improve the performance of @Html.Kendo().DeferredScripts(true)
Thanks,
Faraaz

How can I let users paste ' 123456 ' into my numeric textbox and have it auto-strip the spaces? There are spaces in the beginning and in the end too.
currently if there is any space at the beginning or at the end, it doesn't paste anything, show some sign of exclamation and value disappears.
<kendo-numerictextbox k-format="'#'" ng-model="searchParams.@Model.ParameterName">
</kendo-numerictextbox>
I also tried this where I am making dynamically kendo control as shown below:
<input kendo-numeric-text-box k-format="'#'" ng-model="searchParams.@Model.ParameterName" />
I have tried every possible solution,
Can you please assist how can I achieve this in Angular JS ?
Thanks,
Umair.

Some of the directories I'm listing in the file manager should not be able to accept files being copied or moved into them when an associated record has a certain status. I have scripts working that fire on CopyCommand and MoveCommand, which query a database via an API call. However, I only seem to be able to access the source path in these scripts. Is there a way to also retrieve the destination path?

Working on integrating a Kendo.DropDownList() into a Kendo.Filter object.
It currently works in everyway, other than actually supplying the selected value from the DDL into the datasource / grid binding.
How do I map the Value selected in the Filter Editor Template to the datasource / grid binding. I just need to pass the selected words to be used in the code behind query.
Current Implementation (DDL):
@(Html.Kendo().Filter<KitValidationDtoModel>() .Name("filter") .ApplyButton() .ExpressionPreview() .MainLogic(FilterCompositionLogicalOperator.And) .Fields(f => { f.Add(p => p.OrderId).Label("Davidson Order ID"); f.Add(p => p.EdiOrderId).Label("EDI Order ID"); f.Add(p => p.Rfid).Label("RFID Tracker"); f.Add(p => p.Assy).Label("ASSY"); f.Add(p => p.Control).Label("Control Point").EditorTemplateId("controlTemplate"); f.Add(p => p.Ei).Label("End Item"); f.Add(p => p.Ship).Label("Ship"); }) .FilterExpression(f => { f.Add(p => p.Control).IsEqualTo(""); f.Add(p => p.Ship).Contains(""); }) .DataSource("dataSource1"))
<script type="text/x-kendo-template" id="controlTemplate">
@(Html.Kendo().DropDownList()
.Name("control_filter_dll")
.OptionLabel("Select Control Point...")
.DataTextField("Control")
.DataValueField("Control")
.DataSource(source =>
{
source.Read(read =>
{
read.Action("GetControlPoints", "CustomOrder");
});
}).Events(e => e.Change("onControlChange")).ToClientTemplate())
</script>

I would like my users to be able to renamed or delete files, but not folders. I found the post asking how to prevent subfolders from being created, but delete and renaming seem to be different animals.

Does the ExpansionPanel allow for nested objects within individual panels?
Will it handle the Telerik Grid or Tabs (with even more nesting)?
Is there any change required to make the nested items responsive?
Can the content be loaded using ajax (independently per panel)?
