RadButton, RadPushButton and RadLinkButton can have a custom icon URL and CSS class.

When a CSS class is added, the background-image: url() rule is not rendered initially.

It does not matter what the class holds, it can even be empty

If you hover and leave the button, the icon shows up because the inline rule gets rendered.

The RadToggleButton does not manifest this behavior

You can find attached below a simple repro and workarounds

Just updated the controls and as usual got bitten by the change.  Very simple, we had a button that changed colors based on a change in an edit page.  The Button remained a White Color if nothing was entered, a Green Color if the fields were all correct and a Red Color if the fields were in error.  The determining factor is all behind the seen analysis on a save which has nothing to do with the Button.  Code behind the scenes sets a db value for the status of the Button. We know that the status is being set correctly because activity allowed or disallowed occurs correctly and that the DB settings having been checked are 100% correct as well.

There are seven Buttons with 7 Entry Pages that are affected and the users are totally confused when there is no visual direction as to the problem.

How do we Fix the Button to change Colors

Checkbox buttons are missing when ToggleType='CustomToggle' in Lightweight rendering. The issue is introduced in 2017 R1 release.

Code to reproduce:
        <telerik:RadButton runat="server" ID="btnEnableTrace" RenderMode="Lightweight"
            ButtonType="ToggleButton" ToggleType="CustomToggle">
            <ToggleStates>
                <telerik:RadButtonToggleState PrimaryIconCssClass="rbToggleCheckbox"></telerik:RadButtonToggleState>
                <telerik:RadButtonToggleState PrimaryIconCssClass="rbToggleCheckboxChecked"></telerik:RadButtonToggleState>
            </ToggleStates>
        </telerik:RadButton>

The blue part of the radio and check buttons is gone in 2017.1.xxx. There is a slight hover highlight, but in general, it is drastically different from the previous version (2016.3.1303).

The new appearance can be seen at

Workaraounds:
- Use the Lightweight RenderMode
- OR, use the RadCheckBox control instead

Steps to reproduce:

			<telerik:RadSkinManager runat="server" ID="rsm1" ShowChooser="true"></telerik:RadSkinManager>
			<telerik:RadButton ID="rbFileLink" runat="server" ToggleType="CheckBox" ButtonType="ToggleButton"
							   Checked="true" AutoPostBack="false">

select an item from the dropdown, different than "1"
expected: buttons become enabled
actual: radbutton is still disabled

Having an initially disabled button that is later enabled on the client does not apply the hover effect (rbHovered class is not appended to the DOM element in mouse over). 

You can use RadPushButton instead of RadButton (http://demos.telerik.com/aspnet-ajax/pushbutton/overview/defaultcs.aspx), which works properly in this scneario.

Common scenario is to use PrimaryIconCssClass and SecondaryIconCssClass to decorate custom icons. Common situation is using bootstrap's classes for the glyphicons.

In order to workaround this you can use custom CSS rules and define the expected content properties for the before elements. This is an example with bootstrap icons (http://glyphicons.bootstrapcheatsheets.com/). 


<style>
    .rbPrimaryIcon.glyphicon-filter:before,
    .rbSecondaryIcon.glyphicon-filter:before {
        content: "\e138";
    }
</style>

<telerik:RadButton ID="RadButton2" runat="server" 
    Text="Filter" ButtonType="SkinnedButton" 
    Icon-PrimaryIconCssClass="glyphicon glyphicon-filter" >
</telerik:RadButton>

Using RequiredFieldValidator with RadButton (ToogleButton type), RadRadioButtons and RadCheckButtons throws a server exception that cannot be validated. 

Workaround:



ASP.NET:

<telerik:RadRadioButtonList ID="RadRadioButtonList1" runat="server" Text="RadRadioButtonList" >

    <Items>
        <telerik:ButtonListItem Text="Item 1" Value="0" />
        <telerik:ButtonListItem Text="Item 2" Value="1" />
    </Items>
</telerik:RadRadioButtonList>
 
<asp:CustomValidator ID="CustomButtonListValidator" ErrorMessage="errormessage"
    runat="server" OnServerValidate="CustomButtonListValidator_ServerValidate" />


C#:

protected void CustomButtonListValidator_ServerValidate(object source, ServerValidateEventArgs args)

{
    args.IsValid = (RadRadioButtonList1.SelectedIndex > -1);
}

This is a duplicate of http://feedback.telerik.com/Project/108/Feedback/Details/210060, see there for a workaround and for status updates.


You can change the DPI settings in Windows from the Display Settings. Setting a size of 125% and clicking on a button will throw a server exception:

Reproduced with latest official (2016.1.113) and internal (2016.2.128) in all browsers. Not reproducible with 2015 Q3 SP1.

Code to reproduce the problem:

    <asp:Button runat="server" ID="GoStep2" OnClick="GoStep2_Click" Text="Next" />
            <asp:Panel runat="server" ID="Panel1">
                <asp:Button Text="aspButton" runat="server" />
                <telerik:RadButton ID="Button1" Text="radButton" runat="server" />
            </asp:Panel>
 protected void Page_Load(object sender, EventArgs e)
    {
        Panel1.Enabled = false;
    }
 protected void GoStep2_Click(object sender, EventArgs e)
    {
        Panel1.Enabled = true;
    }


1 click the Next  button

3. When the page loads after the postback the RadButton remains disabled, unlike the asp:Button.

For the time being you can use the following workaround:
CSS:
	<style>
		.RadButton input {
			width: 100% !important;
		}
	</style>
ASPX:
		<telerik:RadButton ID="rbACH" runat="server" ToggleType="Radio" ButtonType="StandardButton" GroupName="test" AutoPostBack="false" Text="eCheck" Width="200px">
			<ToggleStates>
				<telerik:RadButtonToggleState Text="eCheck" PrimaryIconCssClass="rbToggleRadioChecked" />
				<telerik:RadButtonToggleState Text="eCheck" PrimaryIconCssClass="rbToggleRadio" />
			</ToggleStates>
		</telerik:RadButton>
		<br />
		<br />

		<telerik:RadButton ID="btnToggle" runat="server" ToggleType="Radio" ButtonType="StandardButton" GroupName="StandardButton" Width="200px">
			<ToggleStates>
				<telerik:RadButtonToggleState Text="Checked" PrimaryIconCssClass="rbToggleRadio" />
				<telerik:RadButtonToggleState Text="UnChecked" PrimaryIconCssClass="rbToggleRadio" />
			</ToggleStates>

For the time being you can either set the UseSubmitBehavior property of the button to false or place the following JavaScript workaround below the button's declaration:
ASPX:
	<form id="form1" runat="server">

			var $T = Telerik.Web.UI;
			$T.RadButton.prototype._mouseClickHandler = function (args) {
				var button = this, result;

				finally {
					button._mouseUp(args);
					button._restoreFlags();
					setTimeout(function () { Page_BlockSubmit = false; }, 0);
					return !result ? $telerik.cancelRawEvent(e) : true;
				}
			};

			function simulateMouseEvent(element, eventName, args) {
				var o = $telerik.$.extend({}, args || {});

The icon of a checkbox button appears over the text when the configured width is not enough to display them both on one line in Classic render mode.
