Suddenly all my projects tell me to 'Convert to Telerik Web Site' but they all are already are?

All projects are affected. If I try to convert and choose a different skin this seems to affect the installation, but the button 'Convert to Telerik Web Site' is still visible.

Is there a way to fix this?

The menu commands for Telerik projects sometimes are not visible. The reason why is that the visibility state of the commands is evaluated asynchronously. Depending on the time it takes to evaluate the command state, sometimes the commands are not available when they are queried for the first time.

NOTE: It can be observed in all Telerik products.

Due to recent changes to the keyboard accessibility of the RadMenu (i.e. it is now only accessible using the arrow keys instead of moving around using tabs), mega menus are no longer keyboard accessible.

We have designed a mega menu using a telerik RadSiteMap embedded in a RadMenu control, as suggested in the Telerik Demo site:

However, this is no longer accessible. Previously, you could open the dropdown by pressing the down button, then move around in the dropdown using tab. Now, however, pressing tab just closes the dropdown.

We need the menu to be accessible in one way or another.

I'm unsure whether this is an actual bug, but I can't seem to clear the selected text in the RadDropDownTree when i use UncheckAllNodes or UnselectAllNodes from the server side.

I try to to set SelectedText and SelectedValue on the RadDropDownTree control to string.Empty but neither works.

The nodes are unchecked though, but the text showing the previous selection is still visible after i  reload the page.

What should I do to also set the text to represent the selection done by UncheckAllNodes?


Kind regards,

The following commands are missing:

The following commands are available but are not expected to be available:

The contrast between the colors for the background and the text in the Tooltip of the Chart series is very low (dark background and black text).

The problem is most obvious in the Outlook, Simple, Web20 and Sunset skins. 

Workaround would be  setting the Color property for the ToolTipAppearance to White

There are issues with the cursor location when clicking at the end (or to the right) of a line in bullet lists with multiple levels.

When clicking at the end of the line the cursor is unexpectedly placed at the beginning of the line instead of at the end.

This does not happen if you click on some of the actual text or hit the exact location of the last character of the line, but when you naturally click just to the right of the end of the line.

It seems that it does not happen on all levels, but only some, as I have tried to depict in the attached screenshot.

This behavior was replicated on the latest WebForms Editor demo at

Setting EnableEmbeddedSkins="false" in RadGrid when FilterType="HeaderContext" is not applied to the ListBox (filterCheckList) hence the following error is thrown:

Telerik.Web.UI.RadGrid+RadListBoxShared with ID='filterCheckList' was unable to find an embedded skin with the name 'MY_THEME'

The submenu with filtering options has elements that overflow the sliding element:

This issue is reproducible on your demo page:

  • Navigate to the sample drop down list control.
  • Open the list.
  • Select an item either by typing the first letter of an item or using the arrow keys.
  • Press the <Enter> or <Tab> key.

The expected behavior is the drop down list will close. It does not. However, if you collapse the list with the mouse or <Alt>+<Up Arrow> and then open the list again, the <Enter> and <Tab> keys will behave as expected.

As this problem is also present on your demo site, it is likely a bug with the RFD product and not our specific use case. If there is an update to the product or a JavaScript workaround, that would be greatly appreciated.

The Timeline generated two duplicate span elements with the same ID:

<span id="ctl00_ContentPlaceholder1_RadTimeline1_WebServiceCDS" style="display:none;"></span>
<span id="ctl00_ContentPlaceholder1_RadTimeline1_WebServiceCDS" style="display:none"></span>

This can be seen in the Overview demo:

The RadMultiSelect implementation has one error that WCAG 4.1.1 parsing is catching. There is a duplicate span with the same id.

Found in the page source of the demo page (similar to how I implemented as well):

<select name="ctl00$ContentPlaceholder1$RadMultiSelect1" multiple="" id="ctl00_ContentPlaceholder1_RadMultiSelect1" class="RadMultiSelect RadMultiSelect_Silk" style="width:400px;">
<span id="ctl00_ContentPlaceholder1_RadMultiSelect1_WebServiceCDS" style="display:none;"></span><input id="ctl00_ContentPlaceholder1_RadMultiSelect1_ClientState" name="ctl00_ContentPlaceholder1_RadMultiSelect1_ClientState" type="hidden" />
</select><span id='ctl00_ContentPlaceholder1_RadMultiSelect1_WebServiceCDS' style='display:none'></span>

When a RadGrid has the "AllowScroll" property set to True and is populated via a DataSourceID, calling the ExportToExcel() method on the grid results in the grid immediately rebinding. This undoes any changes made to the grid, like during the recommended way to export Template columns. When AllowScroll=False, the grid does not rebind and Template columns are exported, as expected.

When EnablePostBackOnRowClick="true" and clicking on the RadAutoCompleteBox inside the EditItemTemplate the Grid will make a PostBack.

This issue does not happen with other elements (span, input, button, etc).
