Hi Telerik,

Just a heads-up - some of the demo pages are generating errors:

I have found this on:

Hi,

A Feature suggestion to develop a drag-drop Interactive Forms builder, rather than programmatically design a Form. This Feature would simplify and reduce design time to create an Interactive Form for a Designer/User and could be directly integrated into existing applications.

Dear staff I know this post

https://www.telerik.com/support/code-library/detecting-changes-to-the-radeditor

But in any case the component RadEditor have the method 'OnTextChanged' in the client side.

Probably, id it doesn't works, is better to remove it.

Thanks

Hi,

I was looking around to develop a web app that allows streaming camera view in order to take pictures, showing the previews, letting cancel/retake or transfer (upload/save) them.

I started from the input control, that makes more or less what I need, but start a video streaming, letting the user simply to capture frame from it to save pictures, is more user friendly and simplify a lot the workflow.

So I started to work with video element, canvas and FloatingActionsButton, hitting against many issues, starting from the different browsers compatibilities.

I was just wondering if Telerik would never implement such a camera + gallery component, in order to take and manage pictures easily and cross platform.

Thank you, kind regards

Currently, when the grid is set to:

<ClientSettings EnablePostBackOnRowClick="true">

The post back will be fired even if the clicked row is already selected, which sometimes is not good.

To solve this we need to write a javascript event on rowclick to cancel the event if the row is already selected, but it will be nice to have this as a built in setting like 

<ClientSettings EnablePostBackOnRowClick="true" PostBackOnRowClickOnSelectedRow="false">

Thanks,

ilan.

While changing the value from RadCombox, meaning firing the SelectedIndexChanged, I am getting the below error.

When trying on localhost SelectedIndexChanged of RadCombobox is getting fired and rgrid_NeedDataSource of RadGrid is not fired but when deployed on IIS, the scenario is opposite, SelectedIndexChanged is not fired but rgrid_NeedDataSource is getting fired.

Please help.

Also another thing, I wanted to understand how to use licenses.licx file in our project for telerik dll version 2013.1.314.45?

The RadSignature has the option to reset the contents of the signature but it would be great to make an event like a OnReset or OnClear so I can set the status of other objects on my page.

RadImageGallery is a great control and supports many image formats out of the box (JPEG, PNG, BMP, etc.)

However, it does not provide native support for HEIF.  HEIF is now the default format for most Apple devices (anything after iOS 11 update).

It would be great if RadImageGallery were updated to provide support for this format so that developers don't have to force image conversions of photos taken by Apple devices.

The issue can be replicated with AutoCompleteBox demo: https://demos.telerik.com/aspnet-ajax/autocompletebox/examples/default/defaultcs.aspx

Set the SingleLineEntries property to "Enabled", and add a new Entry to the AutoCompleteBox. At this point, the page will scroll up and as a result hiding the AutoCompleteBox.

I just installed the latest release (Telerik_UI_for_ASP.NET_AJAX_2023_1_314) and the program gives me an error.

This is the error :

similar to these:

http://willowsystems.github.io/jSignature/#/demo/
http://www.supersignature.com/

Sure you could do something really cool like a sketchpad, with a background image.

Hello,

Can you please add the control ID to this error so the affected control can be easily identified?  Right now, if you have a page with multiple combo boxes, it is extremely time consuming to locate the one with the issue.

Thank you,
DJ

Hi,

currently the only way to set the translation for the "All" option that is created through the enabled "EnableAllOptionInPagerComboBox" property is to set the translation in the "RadGrid1_ItemDataBound" method, which is described here: Localization on RadGrid: Paging Option All

It's a workaround for a missing localisation. By setting the translation in the RadGrid1_ItemDataBound method the if-statement is being checked for every row processed, which is not good for performance.

Could you please make it possible to set the translation with a property and have the default value set in the resource file of the grid?

Thank you.

Scenario: need dynamically change header test on dropdown change, while retaining HeaderContext filter type icon

After conversation with support created this request

Description:
'Selected' state is not defined for 'Pagination controls' in entire page.

Environment (OS, Application, Versions):
OS: Windows_11
Version: 21H2
OS Build: 22000.856
Browser: Microsoft Edge Version 105.0.1343.33 (Official build) (64-bit)
URL: https://demos.telerik.com/aspnet-ajax/grid/examples/overview/defaultcs.aspx
Screen Reader: NVDA(2022.2)

Repro Steps:
1. Open URL:https://demos.telerik.com/aspnet-ajax/grid/examples/overview/defaultcs.aspx page in Edge Browser.
2. Navigate to pagination controls present below "Book A Car' table under 'Overview'.
3. Open NVDA.
4. Navigate to 'Selected button' on pagination controls.
5. Observe an issue that 'Selected' state is not defined for 'Pagination controls'.

Actual Result:
'Selected' state is not defined for 'Pagination controls' in entire page.

Expected Result:
State 'Selected' should be defined on pagination controls. In this case, the expected role is {button or has a pop-up}. All components need a proper role attribute, ideally with semantics. In rare cases a role attribute should be added to give full context and information to assistive technology. Learn more by reading about when to use an aria role and the html/aria role mappings.
