Currently, the asp:Label and telerik:RadLabel are rendering the AssociatedControlID of the ComboBox as for="RadComboBox1" while it should be for="RadComboBox1_Input"

FROM ADMIN:

<script type="text/javascript">
    function fixLabelFor() {
        $telerik.$("label[for]").each(function () {
            var lbl = $telerik.$(this)
            if ($telerik.$("#" + lbl.attr("for")).hasClass("RadComboBox")) {
                lbl.attr("for", lbl.attr("for") + "_Input");
            }
        })
        // Sys.Application.remove_load(fixLabelFor); 
    }
    Sys.Application.add_load(fixLabelFor);
</script>

<script>
    function OnClientLoad(sender, args) {
        var ariasettings = JSON.parse(sender._ariaSettings)
        if (ariasettings && ariasettings["aria-describedby"]) {
            var lbl = $get(ariasettings["aria-describedby"]);
            lbl.setAttribute("for", lbl.getAttribute("for") + "_Input")
        }
    }
</script>

The Telerik Bootstrap skin looks like it is Bootstrap, but it is not.  While it is easy to override a Bootstrap style to customize something, every time we do we end up on a support ticket to figure out how to make the same override in the skin.

One common area this comes up is the form sizing.  In Bootstrap, you can use a CSS class .form-group-sm to easily make the form controls smaller.  (There are several other classes as well for controls and form groups.)  The Telerik controls, like radCombobox or DatePicker do not honor this style, you need special Telerik CSS to get them to size.

The Bootstrap skin should have CSS included in it that handles when the Bootstrap control size classes are used.  That way when a Telerik control is placed in a div with .form-group-sm etc. it will automatically resize itself accordingly.

Currently, opening the CustomColorPallete popup always selects the #808080 color.

To have this behavior use the custom code solution below:

<telerik:RadColorPicker runat="server" ID="RCP" EnableCustomColor="true" OnClientLoad="OnClientLoad" />

<script>
    function OnClientLoad(sender, args) {
        $telerik.$(sender._customColorButton).click(refreshPalette(sender));
    }

    function refreshPalette(sender) {
        return function (evt) {
            var colorPicker = sender;
            var selectedColor = colorPicker.get_selectedColor() || "#808080";
            colorPicker._updateHslPaletteElementsUI(colorPicker._getRgbFromHex(selectedColor), null, true);
        };
    }
</script>

When track changes disabled the backspace is OK:
- User typed two lines (1) & (2)
- At the beginning of the line (2) user presses the backspace key, it successfully appended the line (2) with line (1) (where there was a space available). 
When track changes enabled the backspace does not work as expected:
- User typed two lines (1) & (2)
- At the beginning of the line (2) user presses the backspace key, it removes the end of the character in line (1).

 Hello,

I have noticed the changes in your website, demos and documentation, but not all seems to work well on IE 11.

In the new interface of

 https://docs.telerik.com/devtools/aspnet-ajax/introduction?_ga=2.16776693.2130593711.1599296842-392310183.1565849466

 the left menu dissapear after more clicks (IE11)

However, in ASP.net AJAX demos, the new interface is not looking good on IE 11

For example,  https://demos.telerik.com/aspnet-ajax/orgchart/examples/expandcollapse/defaultcs.aspx

The old interface was looking great, I had no problems at all, any control

I hope I will not have the same problems in my ASP.net application... 

Possible BreadCrumb integration with RadMenu and Orgchart:

I suggest update Device Screen Size for 

Telerik.Web.Device.Detection

using System;

namespace Telerik.Web.Device.Detection
{
    /// <summary>
    /// The device screen size based on the its dimensions in CSS pixels
    /// </summary>
    /// <remarks>
    ///The default ranges are:
    /// Small (to 600) CSS pixels
    /// Medium (601-1024) CSS pixels
    /// Large (1025 - 1366) CSS pixels
    /// ExtraLarge (over 1366) CSS pixels
    /// FullHD (over 1920) CSS pixels
    /// UHD4K = 5 // 3840
    /// UHD8K = 6 // 7680
    /// UHD10K = 7 // 10240
    /// </remarks>
    public enum DeviceScreenSize
    {
        Small = 0, // 0-600
        Medium = 1, // 601-1024
        Large = 2, // 1025 - 1366
        ExtraLarge = 3 // over 1366
        FullHD = 4 // 1920
        UHD4K = 5 // 3840
        UHD8K = 6 // 7680
        UHD10K = 7 // 10240

    }
}

Best,

Hi,

Is it possible to exercise the NullText option for the control RadDatePicker for ASP.NET AJAX

Thanks

Gita

I know that you have developed a RadBook, but only for Silverlight and WPF, which limits the visualization in devices in which it is not possible to install that plug-in or OS, so it would be good to have an HTML5 type control for ASP.NET UI with all the functionality of a Flip Book, and that the control can read a list of images, PDF, Office files, and other.

Thank you.

Some of the Red controls can be used for server side only (no UI).
I typically use RadGrid to perform something that it is good at (grouping and arranging data) then export it to Excel. 
So if the UI is actually and output file this can be very handy, why have a web interface if you are actually created a report of some kind.
You had a Reporting tool kit, but times have moved on to Self Service and PowerBI type tools. It just seems that you have a lot of code in DLL that could be repurposed for process pipelines, not for a web interface, tho  the final results could be reused there.

Add HLS live streaming support to the RAD Media Player.

One tool that can help with testing for the contrast ratio is ANDI.

From Admin: Share in this thread the most impactful contrast issue here, sharing the control and its setup, the skin and the exact elements that are failing the contrast test.

Hi Team,

I'm using Telerik.Web.UI Version 2020.2.617

I have integrated it and added a reference in my web application, asked me to upgrade the version of Assemblies "System.Web.Extension.dll" and "System.Core.dll" has to be upgraded to version 4.0, I did that too, Now I'm getting an error while I'm running or doing build "The type or namespace name 'Script' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)", Assembly it is referring to "System.Web.Script.Services", same error is coming for other attributes like "ScriptMethod, ScriptMethodAttribute"

For the Key word "this" it is throwing as below error

It is throwing an error for "System.Linq.Expressions"

Can anyone help me out on this how to resolve these bugs.

Regards

P L P Kumar
