In IE11, checkboxes are rendered as a flat style with a black checkmark, as apposed to the 3D look rendered by IE9. When using a RadTreeView with checkboxs and form decorator, the checkboxes are not styled to look like the 3D ones. Checkboxes that are not in trees are styled, and therefore, the checkboxes look differently. It's expecially apparent when both treed and non-tree checkboxes are on the same page. See my support ticket 815961 for my question about this.

A JavaScript error is thrown when a hidden AccessibleRadEditor is loaded in IE 10. The error message is:

"SCRIPT5007: Unable to get property 'get_element' of undefined or null reference "

Code to reproduce the issue:

        <asp:Button ID="btn1" runat="server" Text="Show Editor" OnClientClick="showEditor(); return false" />
        <div id="div1" style="display: none">
            <telerik:AccessibleRadEditor ID="AccessibleRadEditor1" runat="server" ></telerik:AccessibleRadEditor>
        </div>
        <script>
            function showEditor() {
                $telerik.$("#div1").show();
            }
        </script>

RadAsyncUpload throws a javascript error:

SCRIPT16389: System.NullReferenceException: Object reference not set to an instance of an object.
   at System.Windows.Browser.ManagedObjectInfo.Invoke(ManagedObject obj, InvokeType invokeType, String memberName, ScriptParam[] args)
   at System.Windows.Hosting.ManagedHost.InvokeScriptableMember(IntPtr pHandle, Int32 nMemberID, Int32 nInvokeType, Int32 nArgCount, ScriptParam[] pArgs, ScriptParam& pResult, ExceptionInfo& pExcepInfo) 

when Silverlight module is used and uploading is canceled.

In order to replace the image we use the 'pasteHtml()' API method (http://docs.telerik.com/devtools/aspnet-ajax/controls/editor/client-side-programming/methods/pastehtml). Unfortunately, we have faced the issue in the latest version of Telerik RadEditor (2016.3.1027.45). 


If parent 'div' has "float:left" style settings, the 'pasteHtml()' API method inserts a new image beyond the parent 'div' element. The issue is reproducible in IE11, and it is not reproducible on in the FF and Chrome, Edge and IE10.


Steps to reproduce:
1. Open the demo page http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
2. Switch to the 'HTML' mode of the RTE and replace all existing HTML content with the following HTML snippet:
***
<div style="float: left;">
<img alt="" style="margin: 0px 30px 30px 0px; width: 200px; float: left;" src="../../images/top_image.png" />
</div>
***
3. Switch to the 'Design' mode of the RTE and click once on the image;
4. Open the browser console (F12) and execute the following API code in the console:
$telerik.radControls[11].pasteHtml('<img alt="" src="/aspnet-ajax/Editor/images/UserDir/Marketing/Tokyo.png" />')

Actual Result:
A new image is inserted beyond the parent 'div' element.
***
<div style="float: left;">
</div>
<img alt="" src="/aspnet-ajax/Editor/images/UserDir/Marketing/Tokyo.png" />
***

Expected result:
A new image is inserted into the parent 'div' element.
***
<div style="float: left;">
<img alt="" src="/aspnet-ajax/Editor/images/UserDir/Marketing/Tokyo.png" />
</div>
***

Configuring ItemType and Items properties of RadSlider through the properties window in Visual Studio is not possible (leading to errors).

Certain controls just add bloat to a page.  Like the RadListView is a GREAT control to use inplace of the asp Repeater, but I find I often don't use it (or limit it's use) because it brings down 99.9% useless client scripts.  Most of the time, especially in Sitefinity its a server-side render-only control.  Just used to show data...we don't need ANY client manipulation.

Was poking around on the media player demos page in FF and I noticed that your transitions for the overlays are animating out with javascript?

Why are we doing this on a new control...I know you guys like maintaining consistency...but it makes the control feel so "dated" as the elements choppily disappear.

RadEditor allows the copy and paste of images directly into the Editor content area. The Editor converts this images to a base 64 string and includes them in the HTML.

What would really be great is if it could instead convert the image to a file, perhaps even from the base 64 string, and save it server side, and instead add an img tag referencing the saved file. This would be very useful for when the editor is being used for sending emails (less space) and even creating content as the file would be able to be cached.

It's already being done in the TeamPulse product when a screenshot or other image is pasted into the editor. Please extend this functionality to be built into the AJAX version.

Basically, I would like to be able to set a default state for the menu (which menu is open and which menu item has focus) in code behind (like the Page Load event).

The menu would start off showing the designated menu as open and the designated menu item would have focus but the user would still be able to hover over other menus to open them (the default open menu would then collapse).

If the user ends up moving the mouse off the menu without clicking anything, the menu would then automatically revert to the default state set in Page Load.

Currently, the only way to implement this functionality is to use hidden fields to store the open menu/focused menu item info (on Page Load) and then capture a bunch of JavaScript client events to setup the default menu state, collapse the menu when a different menu is hovered over and reset the menu to the default state when the mouse moves away without clicking.

It works but it's a lot of client code and occasionally the JavaScript events don't fire correctly (or in the correct sequence) and the menu won't reset properly or maybe the sub menus will overdraw each other.

It's a lot of work for something that I think should be built into the core RadMenu control. I'm also concerned about using so much JavaScript because I've been developing web apps for 15 years (using Telerik for 10 years) and every few years all my JavaScript code breaks (due to browser changes) and has to be rewritten. I'd much rather just set the relevant properties in code behind and let you guys worry about updating the client code.

It would be great to just set the default state in code behind and have the menu reset to that state when it loses focus. You could also have a reset timeout so that the menu will reset after the mouse is off the menu for a set number of seconds.

A quick Google search shows that people have been asking for an easy way to implement this for years.

The RadAsyncUpload control is used on forms with other controls, and sometimes we need to validate the control, that is require that the user uploads a file before the form can be submitted.  We have to use a Customvalidator and check the controls client-side properties to see if it has a file.  But if you set the ControltoValidate property an exception occurs.  
Please support this property so that a radAsyncUpload control can be associated with an ASP.Net validator.

This error comes up often for this control and workarounds have been discussed and posted.  See below

The feature request is the following:

1.  Add an Attribute to the RadComboBox, RadDropdownList (and any other controls that suffer from this issue).

2. Let's call the Attribute   --   AppendIfSelectedValueMissing.

3. This attribute would be a boolean (True / False).  Default is FALSE.

4. If AppendIfSelectedValueMissing=True  then when the value of record is being Databound to a RadComboBox, RadDropDownList, etc.  A check (or Try/Catch) would occur to ensure that the Value exists in the DataSourceList and if it does NOT exist in the list then the SelectedValue would be Appended to the List.  Thus, eliminating the "Selection out of range, Parameter, Value" error.

This occur often because some lists get changed over time; however, the historical data may have a value that is no longer on the list -- thus triggering the error.

For example, let's say we ask for a user's Favorite Color.  Our original list was:
Red, Green, Blue

but for some reason -- management, changing user requirements, etc. the new list is

Red, Orange, Blue

Now, if we DataBind a RadComboBox to a historical record with Green as value, we get the "Selection Out of Range" errror.

What I am proposing is -- if we set the AppendIfSelectedValueMissing = True then 
databinding to a historical record with Green would have the following occur.

List from DB ---   Red, Orange, Blue
SelectedValue --    Green
AppendIfSelectedValueMissing
New List for Ctrl --  Red, Orange, Blue, Green

Thus, the error goes away, the historical data can stay the way it is and the lists can adjust their choices over time.

All good for everyone!!!

Thanks for your consideration. 

MarkFirstMatch and Filter functionalities are not supported when checkboxes are enabled, as specified in the Checkbox Support help article. If you remove these two functionalities, the Check All checkbox works as expected.


I want to have on the MarkFirstMatch and the filter on and the "all" to be shown.

An error is thrown when RadButton NavigateUrl is defined in content page with tilde and the master page is up one level.

Workaround: Remove the tilde from the navigate url.

The correct format should be ISO 8601:
([CreateDate] >= '2013-06-22T00.00.00') AND ([CreateDate] <= '2013-06-22T23.59.59'

Workaround: https://www.telerik.com/support/kb/aspnet-ajax/grid/details/get-sql-compliant-filterexpressions-from-radgrid

Color items should persist the Title property/attribute so that when hovered, the text to be shown in the tool.

When it is not possible to load scripts/styles from CDN, the scripts and styles should be loaded from embedded resources.
