For the time being the select can be skipped from decoration:
<telerik:RadFormDecorator runat="server" ID="rfd" DecoratedControls="All" ControlsToSkip="Select"/>

There is also a script attached that provides a workaround for this issue.

The tooltip is not showing when RadFormDecorator decorate asp:CheckBox and asp:RadioButton. For example:

<telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" DecoratedControls="All" />
  
<asp:CheckBox runat="server" Text="Update" ToolTip="Update Last Name" />
<asp:RadioButton runat="server" Text="Update" ToolTip="Update Last Name" />

------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Removing the title attribute from the label element fixes the issue: 

<telerik:RadScriptManager runat="server" ID="RadScriptManager1">
    <Scripts>
        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
    </Scripts>
</telerik:RadScriptManager>
 
<telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" DecoratedControls="All" />
 
<script type="text/javascript">
    function pageLoad() {
        $telerik.$("label[class*='rfdRadio'],label[class*='rfdCheckbox']").removeAttr("title");
    }
</script>
 
<asp:CheckBox runat="server" Text="Update" ToolTip="Update Last Name" />
<asp:RadioButton runat="server" Text="Update" ToolTip="Update Last Name" />

RadFormDecorator does not update properly the state of the grid row checkboxes when Select all checkbox is clicked and the skin is different than Default.

video - https://www.screencast.com/t/lwAfXhgEAs

The bug is introduced with R1 2017 release.

Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/formdecorator/examples/formdecoratorandtelerikcontrols/defaultcs.aspx?skin=Silk
2. Click the "Select All" checkbox of the first Grid

Result: The row checkboxes are not checked

ISSUE 2: Batch Edit mode checkboxes are not updated. Change a few checkboxes in this demo, they all remain unchecked after you close the cell: http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx
Workraounds:
- remove the RadFormDecorator
- OR, have it skip checkboxes, e.g.: DecoratedControls="All" ControlsToSkip="CheckBoxes"

The issue manifests under IE and Firefox when you change the selected radio button. It stems from any other control with RenderMode=Lightweight that brings the font icons the lightweight mode brings.

Workarounds:
- use the same render mode for all the controls (for example, move the form decorator to RenderMode=Lightweight)
- OR, add the following CSS rule to your page to remove the font icon content from the radio buttons
        .RadForm .rfdRadioUnchecked.p-i-radio:before,
        .RadForm .rfdRadioUnchecked:before,
        .RadForm .rfdRadioChecked.p-i-radiobutton:before,
        .RadForm .rfdRadioChecked:before,
        .RadForm .rfdCheckboxChecked:before,
        .RadForm .rfdCheckboxUnchecked:before {
            content: "";
        }

RadFormDecorator with RenderMode="Classic" and Silk skin renders the backgrounds of the decorated textboxes/textarea elements in gray. The issue can be seen on http://demos.telerik.com/aspnet-ajax/formdecorator/examples/rendermodes/defaultcs.aspx?skin=Silk.

Workaround: To solve the issue, switch to Lightweight RenderMode or overwrite the gray background with the following CSS class:

    <style>
        .RadForm.RadForm_Silk.rfdTextbox input[type="text"].rfdDecorated, .RadForm.RadForm_Silk.rfdTextbox input[type="password"].rfdDecorated, .RadForm.RadForm_Silk.rfdTextbox input[type="search"].rfdDecorated, .RadForm.RadForm_Silk.rfdTextbox input[type="url"].rfdDecorated, .RadForm.RadForm_Silk.rfdTextbox input[type="tel"].rfdDecorated, .RadForm.RadForm_Silk.rfdTextbox input[type="email"].rfdDecorated, .RadForm.RadForm_Silk.rfdTextarea textarea, .RadForm.RadForm_Silk.rfdTextarea textarea[disabled].rfdDecorated:hover, .RadForm.RadForm_Silk.rfdTextbox input[disabled][type="text"].rfdDecorated:hover, .RadForm.RadForm_Silk.rfdTextbox input[disabled][type="password"].rfdDecorated:hover, .RadForm.RadForm_Silk.rfdTextbox input[disabled][type="search"].rfdDecorated:hover, .RadForm.RadForm_Silk.rfdTextbox input[disabled][type="url"].rfdDecorated:hover, .RadForm.RadForm_Silk.rfdTextbox input[disabled][type="tel"].rfdDecorated:hover, .RadForm.RadForm_Silk.rfdTextbox input[disabled][type="email"].rfdDecorated:hover {
            background-color: white !important;
        }
    </style>

Workarounds:
- Use the Lightweight render mode of the FormDecorator;
- Use RadCheckBox instead of asp:CheckBox;
- Use the following styles:
.rfdRadioChecked::before, .rfdRadioUnchecked::before,
.rfdCheckboxChecked::before, .rfdCheckboxUnchecked::before {
    content: none !important;
}

ISSUE: Screenshot of this issue can be seen at :
(1) https://goo.gl/knpdiq 
(2) and also at https://goo.gl/8tDqKe. 

The issue is that the drop down width is not matching the width of top part when a select element is styled by FormDecorator. I am using the latest version i.e. 2017.3 913.

HOW TO REPRODUCE: 
Go to the demo page of FormDecorator at http://demos.telerik.com/aspnet-ajax/formdecorator/examples/overview/defaultcs.aspx.
Expand the only select element on this demo page and you will notice that drop down width is not matching the top part width.

RESOLUTION: 
When I tried to resolve this problem, I came up with a solution that works across all skins and render modes as well as all modern browsers of Chrome, Firefox, Opera, Edge + IE 9,10 and 11. 

The solution involves overriding the method Telerik.Web.UI.RadFormDecorator.prototype._expandHeader.  JavaScript for overriding this method is given in attached file. Just copy this script and paste in anywhere in your aspx page to resolve this issue.

ISSUE:  Screenshot of this issue can be seen at https://goo.gl/F8C73V. 

This issue occurs in classic render mode when an option has long text that gets truncated instead of being wrapped.

HOW TO REPRODUCE:
Use the following page code to reproduce it. Expand the drop down and notice that the option just after None is truncated and not wrapped.

Use the following page markup to reproduce this problem.

<%@ Page Language="C#" AutoEventWireup="true" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

        </select>

        <button id="btn1">Postback</button>

    </form>
</body>
</html>

RESOLUTION:
Add the following style in your aspx head part based on the skin you are using for FormDecorator.

If skin is any one these big skins -  MetroTouch or BlackMetroTouch or Material or Silk or Glow or Bootstrap, then use the style below.
    <style>
        div.rfdSelectBox ul li {
            min-height: 16px;
        }

        .rfdSelect {
            min-height: 32px !important;
        }
    </style>

For all other skins, use the style element as below.

    <style>
        div.rfdSelectBox ul li {
            min-height: 16px;
        }

        .rfdSelect {
            min-height: 32px;
        }
    </style>

Steps to reproduce:
1. Load https://demos.telerik.com/aspnet-ajax/formdecorator/examples/overview/defaultcs.aspx on IE 11
2. Input two lines in the textarea
3.  Select the second line from right to left by holding the left mouse button and releasing it when the cursor is outside of the text area


4. Press button 'delete' from keyboard with multi select content 
=> result: Can not delete content


5. Press button 'backspace' from keyboard 
=> result: back from url....


The problem happens only in IE when there is a select element on the page and when the mouse goes outside the boundaries of the textarea.

JavaScript error is thrown on the page, when a classic DropDownList is clicked in application running with .NET 3.5, debug mode.

Error message:

"Uncaught Sys.ParameterCountException: Sys.ParameterCountException: Parameter count mismatch."

Steps to reproduce:
1. Run this code with .NET 3.5 and <compilation debug="true">
        <asp:ScriptManager ID="sm" runat="server" ScriptMode="Debug">
        </asp:ScriptManager>
        <telerik:RadFormDecorator runat="server" EnableRoundedCorners="true" DecoratedControls="All" />
        <asp:DropDownList runat="server">
            <asp:ListItem Text="text1" />
            <asp:ListItem Text="text2" />
        </asp:DropDownList>

2. Click the drop-down button.

Result: A JS error is thrown.

This happens because under .NET 3.5, in the .debug.js version of the MS AJAX scripts, the Function$emptyMethod() method RadFormDecorator uses has parameter validation and throws errors when you pass any arguments. This is not present in release and seems to not be present in newer versions of .NET

You can choose one of the following workarounds:

1) Set the ControlsToSkip="GridFormDetailsViews,LoginControls,ValidationSummary"  property of the decorator.

2) Set the AllowFilteringByColumn property of the grid to false.

3) Remove the GridDateTimeColumn column of the grid.
