Currently, it's not possible to add Alt text to ImageGalleryItem. By Default it will add "Main Image" as alt.
We can do it in Image Thumbnail but not in the Image Gallery Item, this causes issue with the W3CAG which requires to add alt text to image.
It will be great add on if we can implement this feature to make RadImageGallery accessible.
We have requirements for 3 HtmlCharts showing related data, all with the same dates on the X-axis. There would be too much data to put all series on a single chart.
Each chart has a Navigator. When we want to view a timeframe different to the default, all charts must have the Navigator adjusted separately. It would be a useful feature if a single navigator could change the display of multiple charts.

Hi Telerik,
Just a heads-up - some of the demo pages are generating errors:
Server Error in '/aspnet-ajax' Application.
Runtime Error
Description: An exception occurred while processing your request. Additionally, another exception occurred while executing the custom error page for the first exception. The request has been terminated.
I have found this on:
Test Environment:
OS: Windows_11
- Open URL: https://demos.telerik.com/aspnet-ajax/grid/examples/overview/defaultcs.aspx page in Edge Browser.
- TAB to the grid container.
- Observe the issue that the grid container is receiving focus.
Actual Behavior:
Focus moves on non-interactive controls.
Expected Behavior:
Focus shouldn't go to the non-interactive element in table content.
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.
Pasting plain text content from notepad or other text editor into the RadEditor control (design view) results in container HTML tags adding to the content and inline styles that make the text unreadable.
Content pasted:
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut placerat orci nulla pellentesque dignissim enim sit. Diam quam nulla porttitor massa id neque. Ipsum suspendisse ultrices gravida dictum fusce ut. Sed odio morbi quis commodo odio aenean. Sed faucibus turpis in eu mi bibendum neque egestas congue. Sed pulvinar proin gravida hendrerit. Cras semper auctor neque vitae tempus. Nisi porta lorem mollis aliquam ut porttitor leo a diam. Quis vel eros donec ac odio tempor. Tellus in metus vulputate eu scelerisque felis imperdiet proin. Et ligula ullamcorper malesuada proin libero nunc consequat interdum. Neque viverra justo nec ultrices.
Result in RadEditor:
<div class="telerik_paste_container" style="border-width: 0px; position: absolute; overflow: hidden; margin: 0px; padding: 0px;">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

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
