This request feature is tied to ticket #1388825. Refer to that ticket for the illustration of the problem I am referring to. 

Given two splitter windows, all I require is to populate one splitter window with some data related to the other splitter window.

In my case, one Telerik splitter window has a simple 3-level Telerik tree control. When the 3rd level is clicked on, I want the other Telerik splitter window containing a Telerik grid to display details of what was clicked on. This requires an AJAX call to avoid having to reload the tree control.

However, while working with Support, there seems to be a very high degree of rocket science and uncertainty involved with implementing this scenario. 

I would have thought with great certainty that the functionality I need would be clearly documented somewhere in the Telerik doc database. I am still amazed that I might the first person who has this problem.

So, this feature request is to essentially provide very clear and competent documentation on the design pattern one needs to implement AJAX calls which pass data between two Telerik controls. At the very least, it would document the design pattern for the scenario I described above.

Maybe this cannot be done in the 21st Century yet. I don't know what is involved. I'm just a backend developer who purchased a Telerik license so I would not have to spend the rest of my life trying to learn Javascript.

Thank you,

Jay

Hi,

I notice that some of the styling has changed for the Blue Opal theme in the latest release (2019 R1), notably the background colour of the selected page on the grid and the already selected items on a Drop Down List have gone from dark blue to a bright blue (see attached screenshots from demos.telerik.com).

Is this by design or by mistake?

Particularly on the drop down list, this change makes it more difficult to identify the already selected items.

Can this go back to what it used to be - or is there a way of manually changing this setting via the site.css?

Thanks

Kevin

I'm using drawing.drawDOM to create a PDF. I have to make a table of contents in the beginning of the PDF. I've got two issues:

- How do I link to another section of the PDF? <a href="#conclusion">Conclusion</a> and then later <a name="conclusion"></a> doesn't seem to work :-/

- How do I figure out on which page a specific part of the document is being rendered? In my TOC I would like to say "Conclusion....page 22".

This is in reference to the following forum post:

For consistency in the MVC product, it would be a good idea to expose built-in events such as the "change" event for the generic Html.Kendo().TextBox helper. This is provided for other controls like the DateTimePicker and even NumericTextBox (https://demos.telerik.com/aspnet-mvc/numerictextbox/events) but not for TextBox.

As mentioned in my post, this is not an insurmountable problem. I can do what I need by diving "down" into jQuery, but it would be nice to be consistent.

Currently, when an event that is grouped by multiple resources is dragged, it automatically updates the selected resource data with the one that corresponds to the drop target.

The more appropriate behavior would be to be to automatically preposition the event for the rest of the selected resources.

We have a web page critical to the web application. In the absence of a suitable MVC widget we had to use a ASP.Net WebForm ListView control along with ASP.Net Ajax (Accordion for expand/collapse functionality) and JQuery (for client side validation). 
 
The web page accomplishes the following key functional requirements –
 
a. Ability to group products –  Using ASP.Net Ajax we were able to provide the expand / collapse visual effect.
 
b. Ability to enter order quantities very quickly -  a lot of stores place orders at the last minute  (5-10 minutes before order deadline) for valid reasons.  The web page provides a text box inline for quick entry.  On a desktop, the user can traverse the rows within the group using the tab key.   The web page typically contains 150 –  200 products for entry.   With Telerik MVC Grid widget, in the absence of inline editing, having to click on Edit/Update/Cancel buttons dramatically increases the number of clicks / touch / swipe.  Besides, it creates a real estate issue on smaller form factors.  
 
c. Real time validation – using JQuery we were able to validate the row as and when the quantity was entered.  Any error would show below the row in question.  The error would continue to show until the quantity was revised.  The error however, will not stop the user from entering quantities on other rows.  This approach lets the user review any errors in the end.
 

The closest MVC widget we could use from the Telerik collection was the grid widget with grouping.  However, it falls short on points b and c above.  There is probably some workaround available but then we would lose the LOW CODE advantage.

Create a PDF file viewer (like the one in WPF) so users can view PDF files in the web application. And can also control who can read, copy and/or print

It would be nice to have a MultiColumnComboBox as we have it already in WinForms.
A MultiColumnComboBox is a special case of combo box control with Grid integrated in its drop-down. The control combines the functionality and features of DropDownList and Grid.

Currently, if I want to bind an ASP.NET TreeList to an OData DataSource, I have to define the data source using a javascript object:

https://demos.telerik.com/aspnet-mvc/treelist/odata

https://demos.telerik.com/aspnet-core/treelist/odata

I would like to be able to be able to define the OData DataSource using ASP.NET Razor syntax just like the Grid:

https://demos.telerik.com/aspnet-mvc/grid/odata
https://demos.telerik.com/aspnet-core/grid/odata

Thank you.

as of today it is not possible to bind the map markers to signalr.
in grid it works. in kendo map not.

it would be blaze if the map markers would be a observable collection for mvc.this way you could update it through the viewmodel.

Row's hover effect should be optional and it could be enabled/disabled in grid's configuration, the same as we add Selectable, Navigatable, Sortable, Editable, etc., functionalities to grid. This could apply to odd/even coloring too. Should no need to do hacks to achieve this.

Many widgets offer functionality to define a template (header, row, toolbar or whatever) by an id, such a way that the id refers to a html section that actually contains the template like:
<script id="idOfSomeTemplate" type="text/x-kendo-template"> 
<!-- template contents --> 
</script> 

I use this a lot because it's easy to use and whenever the widget is part of another widget (common example: a grid part of a tabstrip) Razor /C# won't allow you to do nested inline markup blocks (@<text> </text>). With the above template it's possible to define the tempalte outside the nested inline block.
Now it seems the MVC wrappers don't have the possiblity to do this for the grid toolbar template. 
TLDR:
I would have expected this templateid method:
@(Html..Kendo().Grid<T>() 
.Name("Grid") 
.ToolBar(toolbar => 
{ 
toolbar.TemplateId("idOfSomeTemplate") 
}) 
) 

In Kendo MVC Grid, the column of type Select() will be good if has an option to show/hide the checkbox in specific rows based on an expression. For example:
.Columns(columns =>
            {
                columns.Select().Visible(m => m.ShowSelect);
            })

Where "ShowSelect" is a property of my Model which is bound to the Grid.

You recently added a checkbox column feature to the grid control. However, you cannot control at the record level if that checkbox should be accessible. Every checkbox is selectable regardless of the data it represents. It would be nice to disable (or hide) the checkbox in the column based on some criteria in the record. 

Possibility to iterate over all manually defined columns and f.i. set width or any other property. 

Hi  I have some question the "ustr" i want use diagram  "https://demos.telerik.com/aspnet-mvc/diagram" link and i don't know what code it's use in method 

public ActionResult _OrgChart(){return Json(DiagramDataRepository.OrgChart(), JsonRequestBehavior.AllowGet);}

please i want to help what i do

It would be nice to have an option to supply the Grid control with a default filter operator as shown below.
The current workaround is long and error prone, because you have to redefine the complete list, the default filter has to be on top. So the ordering matters, that is always a bad idea.

Filterable(filterable => filterable
    .DefaultStringOperator(StringOperatorEnum.Contains) 
   )

The datasource for ComboBox object does not support lambda expressions like ListView (and many other objects). These 'hardcoded' strings are error prone and is causing headaches when altering modelschema's.

DataSource(ds =>
    {
        ds.Custom()
        .Sort(sort => sort.Add("PropertyName").Descending())
        .Transport(tr => 
            tr.Read(read => read.Action("Action", "Controller"}))
        );
    })

Please take a look at this issue where DDLs and CoboBoxes won't submit their values the second time after validation fails and the required field is entered.
This was reported back in 2015 and is still unresolved.
