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.

Right now when hiding individual entries in RadHtmlChart the percentage will change so that the visible items always add up to 100%.

For the data we're displaying, we need to have an option for the percentage to still be the original percentage.

For example. if there are five items that are 20% each, if I hide one I want the other four to remain at 20% and the total to now only add up to 80%.

The current behaviour would instead change these all to 25% each with the total being 100%, which for our purposes is displaying inaccurate data to the user.

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.

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. 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.</div>

See accompanying screenshots.

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.

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.

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 :

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

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.

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.

Hello,

I'm facing JavaScript issues after enabling "Telerik.ScriptManager.EnableHandlerEncryption" on Web.config,

I've just followed Encrypt Telerik WebResource Querystring in order to hide the Telerik version.

After this the RadMenu breaks when i do a PostBack action (by pressing a button), the console outputs the same error when hovering a RadMenuItem and the submenus has stop being displayed.

The console error:

Uncaught TypeError: Cannot read properties of null (reading 'apply')
  at Type.callBaseMethod (Telerik.Web.UI.WebRe...=:6:7353)
  at c.RadMenuItem._createChildControls (Telerik.Web.UI.WebRe...=:5300:49)

  at HTMLDivElement.<anonymous> (Telerik.Web.UI.WebRe...=:6:307)

I've tested this error with version 2020.2.617.45 and 2022.3.913 but the same problem.

Looking in the forum i've found this post with a related issue also a reply has a reference to a private feedback and this last one seems to be the same or almost the same problem, so i've tried to follow the workaround on "global.asax" file and "Page_Load" on the master page without luck.

The steps i've follow:

• Enabling "Telerik.ScriptManager.EnableHandlerEncryption".
• Site seems working correctly.
• I press a RadButton inside a RadAjaxPane.
• Response from server is OK.
• Then i hover the cursor on RadMenuItems on RadMenu.
• Console starts to show the related error explaining above.
• RadMenu stops to present the submenus completely.

I'd like to have another way to workaround this in order to make RadMenu work properly again and keep Telerik version hidden.

Regards
