Hi Team,

I would like to integrate editors based on UIHint for specific fields within my Form/Wizard.  If it is achievable, please update documentation/demos with an example.

Thank you!

Hi Team,

I would like to request to have a section in your documentation where the user could see what the DataSourceRequest and DataSourceResult would appear using different types of data such as OData, Json, and the like.   This way, people could inspect what the data would look like to make sure it is returning correctly, and review the structure of data.

Thank you!

The Customer Download Builder (https://www.telerik.com/download/custom-download) is a great tool to build and download smaller versions of the quite large Kendo bundle in ways that allows a developer to just get the controls they want for their site and also minifies the bundles to aid with this aim. However, these custom bundles don't come with sourcemaps.

It would be great if there was an optional tickbox to provide these as well. This would enable much better DX when debugging issues either live or in local dev environments.

Excel spreadsheet fails to load if the sheet has Charts or TextArea.  The Charts and TextArea are fundamental to us being able to make proper use of the spreadsheet control if we are to allow folks to upload their excel spreadsheet to provide our application functionality.  It is not appropriate for us to use the spreadsheet control if it loses some of the excel spreadsheet items like Chart and TextArea if it were to even load correctly.

Request for this feature support is based on the details in the ticket at the URL:

https://www.telerik.com/account/support-tickets/view-ticket/1461086

I would like to suggest an option when installing or upgrading Kendo MVC project to allow selection or deselection of languages for content and scripts. The extra languages add time to loading the web site and slow down publishing. We only need en-UK and en-US for our main project.

We are moving to automated deployment. Currently when upgrading, we have to manually remove the extra languages which are not required. It would be great to have an option in the wizard to do this when installed and this is set as default for upgrading.

Thanks

I have a problem with the DataSourceRequest Filters that are passed from grid to controller - they are not deserialized as I would expect it.

At the client side, I pass a single Composite Filter with logic: "or" and several Filter Items with same field and operator, but different values:

page=1
pageSize=30
filter=somefield~eq~123456~or~somefield~eq~242615~or~somefield~eq~242617

At the server side, they are not deserialized in the same form as I would expect, but in a recursive way. I would prefer to not convert the whole filter chain in my own code, only to process it in the same way it was sent from the client 

Description 

I am restoring the filter for a Kendo Grid in a Controller from a stored filter string. When there is an exponential (e.g. 1e-9) as a value, FilterDescriptoractory.Create() throws an exception "Expected RightParenthesis". Looking at the filter string it seems to have the correct number of parentheses.

On some occasions exponentials work but I can not determine under which. Under which conditions will exponentials work in filters?

Example 

var filterString = "ShipName~eq~'ShipName1'~and~(Freight~eq~0~or~Freight~gte~1e-9)~and~ShipCity~gt~0";
var filters = FilterDescriptorFactory.Create(filterString);

Hello,

I would like to suggest improvement to the function convertValues which is used in the virtualized datasources in multiple controls (dropdownlist, combobox, multiselect etc).

I've realised (after very long time) that the ValueMapper ajax is called in the initial loading, i.e. when there is no default value set in the control. In my opinion that request is extra unnecessary load and shouldn't happen if there is no value to be checked (mapped).

For example check this screenshot of the link https://demos.telerik.com/kendo-ui/dropdownlist/virtualization

In my code I started to surround with the following if:

if (options.value != "") {
        //value mapper code
    }
    else {
        options.success([])
    }

which stopped the initial value mapper ajax request.

This also helped to have only single value mapper request when there is default value set - otherwise it was generating 2 value mapper requests, one with empty value and another one with the set value.

I reckon this will help many users to improve their code.

Thanks.

Kind regards,

Kristina

Telerik UI for ASP.NET MVC version for custom datasource in the Read method of Transport does not support the method Data(string handler) in order to send additional parameters.

Kendo UI version supports this.

https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/configuration/transport.read#transport.read.data

Is there a workaround for this?

Hi, 

I'm wondering that if it's too much trouble for Telerik to add/implement  Persian Calendar In Kendo UI Products.

respectfully,

Thank you for your consideration,

When using QueryableExtensions.ToDataSourceResult() from Telerik MVC, SQL following gets produced:

.. FROM [RMP].[V_UC_EQUIPMENT_LOG2_LOCALIZATION] WHERE ([Extent1].[LOG_TIME] >= convert(DateTimeOffset, ''2019-03-05 23:00:00.0000000 +00:00'', 121)) AND ([Extent1].[LOG_CLASS_ID] IN (78,7,18,30,19,16,17))

When we filter manually in code with linq, e. g.

..  table.Where(e => e.T_EquiID == 234234) ...

the linq provider produces a parameterized query as follows:

AND (@p__linq__0 = [Extent1].[T_EquiID])...

When using a parameterized query, Sql Server can reuse the execution plan much better saving compile time, which is in our case sometimes a big issue.

Please tell us, why can QueryExtensions do produce parameterized queries.

The "CreateDataSourceResult" function verifies if the given DataSourceRequest "Sorts" list is empty and if the IQueryable provider is Entity Framework. If both are true, it adds a default OrderBy to the query on the first sortable property. This makes sense as EF must be ordered before skipping items.

The following statement checks the given DataSourceRequest and IQueryable:

if (!sort.Any() && queryable.Provider.IsEntityFrameworkProvider())
{...}

This leads to unwanted behavior if the query is already sorted on the server and the corresponding SortDescriptor is removed from the "Sorts" list. This is needed if we want to sort on a viewmodel property that doesn't exist on the EF model.

An additional check should be done on IQueryable to see if it is already ordered to avoid replacing the existing OrderBy with a default one.

if (!sort.Any() && queryable.Provider.IsEntityFrameworkProvider() && queryable.Expression.Type != typeof(IOrderedQueryable<TModel>))
{...}

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

This is in reference to the following forum post:

https://www.telerik.com/forums/helper-for-textbox#lpm4Co4Zy0-PHGzJD_E2mA

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.
