Issue previously reported by others and marked resolved as of R2 2020 in June 2020

However, I am running Chrome 84 with the latest build - 2020.2.617.40.

The issue remains.

Radbutton with type=linkbutton, fails to postback

This button used to open the navigateURL as well as execute codebehind

<telerik:RadButton runat="server" ID="btnPrint" ButtonType="LinkButton" Text="Print Deposit Slip" NavigateUrl="/printform.aspx" Target="_blank" UseSubmitBehavior="false" SingleClick="true" SingleClickText="working..." />

....

End Sub

Reproduction:

<telerik:RadButton ID="RadButton1" runat="server" Text="Submit" EnableEmbeddedSkins="false" EnableEmbeddedBaseStylesheet="false"/>
<telerik:RadCheckBox ID="RadCheckBox1" runat="server" Text="CheckBox" Skin="Default" />

Workaround:

<telerik:RadButton ID="RadButton1" runat="server" Text="Submit" Skin=""/>

Hello All,

I'm using a couple of Radbuttons to enable users to download some forms (in Word). This has stopped working in Chromium based browsers for some reason (new Edge, Chrome). It still works in Internet Explorer. No errors in the browser DevTools and no error on the server either.
It also does not work in Cassini (VS2017).

Not sure where to go from here - can anyone confirm/deny?

TIA - Marcus.

code stub:

<telerik:RadButton ButtonType="LinkButton" RenderMode="Lightweight" ID="btnName" runat="server" Text="Button Text" CssClass="TemplBtn" NavigateUrl="~/assets/someform.docx">
         <Icon PrimaryIconCssClass="rbDownload" />
</telerik:RadButton>

Add table layout to radiobuttonlist control. this will facilitate the use of the control in a dynamic situation where you cannot predict  the number of columns the user wants to have. table layout is available in the standard ASP control and should be in the rad version as well. Furthermore it would make our flexibility increase if the item text of the list items can contain markup language (bold, or div with style) instead of latterly displaying the HTML code as if this was normal text.

Thanks for your great work and keep focus on ASP.NET controls to improve their funtions.

select an item from the dropdown, different than "1"
expected: buttons become enabled
actual: radbutton is still disabled
<asp:Button ID="ButtonTest" runat="server" enabled="true" Text="Test" EnableViewState="False" />
<telerik:RadPushButton ID="RadButtonTest" runat="server" Text="RadButtonTest" Enabled="True" EnableViewState="False" RenderMode="Lightweight"></telerik:RadPushButton>
<asp:DropDownList runat="server" ID="DropDownTest" AutoPostBack="True" OnSelectedIndexChanged="SelectedIndexChanged_Test">
    <Items>
        <asp:ListItem Text="1" Value="1"></asp:ListItem>
        <asp:ListItem Text="2" Value="2"></asp:ListItem>
        <asp:ListItem Text="3" Value="3"></asp:ListItem>
        <asp:ListItem Text="4" Value="4"></asp:ListItem>
    </Items>
</asp:DropDownList>
 
protected void Page_LoadComplete(object sender, EventArgs e)
{
    if (DropDownTest.SelectedValue == "1")
    {
        ButtonTest.Enabled = false;
        RadButtonTest.Enabled = false;
    }
    else//workaround
    {
        string script = string.Format("function f(){{$find('{0}').set_enabled({1});Sys.Application.remove_load(f);}}Sys.Application.add_load(f);",
                                            RadButtonTest.ClientID,
                                            "true");
        ScriptManager.RegisterStartupScript(Page, Page.GetType(), "someKey", script, true);
    }
}

protected void SelectedIndexChanged_Test(object sender, EventArgs e)
{
}

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);
}

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:

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.

RadButton with button type checkbox or radio has incorenct margin in Silk and Glow.

Due to the negative value of the margin, the checkbox/radio button icons are partially hidden.

The following CSS fixes the issue (for Silk skin):
    .rbCheckBox.RadButton_Silk .rbToggleCheckbox.rbIcon, .rbCheckBox.RadButton_Silk .rbToggleCheckboxChecked.rbIcon, .rbCheckBox.RadButton_Silk .rbToggleCheckboxFilled.rbIcon, .rbToggleButton.RadButton_Silk .rbToggleCheckbox.rbIcon, .rbToggleButton.RadButton_Silk .rbToggleCheckboxChecked.rbIcon, .rbToggleButton.RadButton_Silk .rbToggleCheckboxFilled.rbIcon, .rbRadioButton.RadButton_Silk .rbToggleRadio.rbIcon, .rbRadioButton.RadButton_Silk .rbToggleRadioChecked.rbIcon {
    margin: 0 !important ;

RadButton with ButtonType="ToggleButton", ToggleType="CheckBox" or ToggleType="Radio" in lightweight mode, renders the icons and the text labels at incorrect position.

For the time being, you can use the following CSS as a workaround:

.RadButton.rbCheckBox span.rbText,
.RadButton.rbRadioButton span.rbText,
.RadButton.rbToggleButton span.rbText {
    vertical-align: initial; /* FF and Chrome */
    vertical-align: auto; /* IE */
}

button.RadButton {
    vertical-align: initial;
    vertical-align: auto;
}

For the time being the following workaround can be used:
		<script>
			function OnClientClicked() {
				alert('OnClientClicked');
			}

			function OnClientClicking() {
				alert('OnClientClicking');
			}

			function fixBtnClicked(sender, args) {
				sender._useModules = false;
			}

		</script>
		<telerik:RadButton ID="RadButton1" runat="server" ButtonType="LinkButton" Text="Click" OnClientLoad="fixBtnClicked" Target="_parent" NavigateUrl="http://www.google.com" OnClientClicked="OnClientClicked" OnClientClicking="OnClientClicking" />

For the time being you can use the following workaround:
JavaScript:
		<script>
			function fixBtnRepaint(sender, args) {
				sender._useModules = false;
			}
		</script>
ASPX:
				<telerik:RadButton ID="RadButton1" runat="server" Text="Click" OnClientLoad="fixBtnRepaint">
				</telerik:RadButton>

Currently the default height of RadButton with Silk skin and CssClass="rbPrimaryButton" is 28px. The correct height must be auto, so that the text inside the RadButton can be wrapped when it is longer and no height is specified. For the time being the following CSS workaround can be used:
CSS:
        span.RadButton.RadButton_Silk.rbLinkButton.rbPrimaryButton {
            height: auto;
        }
ASPX:

            <telerik:RadButton ID="RadButton1" runat="server" Skin="Silk" ButtonType="SkinnedButton" Text="aaaaaaaaaaa bbbbbbbbbbbbbb cccccccccccc" Width="200px" CssClass="rbPrimaryButton" />
            <telerik:RadButton ID="RadButton3" runat="server" Skin="Silk" ButtonType="SkinnedButton" Text="aaaaaaaaaaa bbbbbbbbbbbbbb cccccccccccc" Width="200px" CssClass="rbSecondaryButton" />

For the time being the following JavaScript workaround can be used:
JavaScript:
		function pageLoad() {
			fixImageURL();
		}
		function fixImageURL() {
			var imageBtns = $telerik.$('.rbImageButton');
			for (var i = 0; i < imageBtns.length; i++) {
				var btnStyle = imageBtns[i].getAttribute('style').replace("background-image:url(", "background-image:url('").replace(");", "');");
				imageBtns[i].setAttribute('style', btnStyle);
			}
		}
ASPX:
		<telerik:RadButton ID="RadButton1" runat="server" Width="50px" Height="50px">
			<Image ImageUrl="50x50.png" />
		</telerik:RadButton>
		<telerik:RadButton ID="RadButton2" runat="server" Width="50px" Height="50px">
			<Image ImageUrl="50x50.png" />
		</telerik:RadButton>

When there is a RadButton with configured ValidationGroup, the client-side ASP.NET validation on the page will not be executed, if there are validation controls, which use the same ValidationGroup. The unexpected behaviour is observed in FireFox and Opera.

If the Target property of the RadButton (ButtonType="LinkButton") is set to a custom string (the name of the target window, where the content of the linked page will be rendered), the link is not opened. For the time being the following workaround can be used:

JavaScript:

    <script>
        function OnClientClicked(sender, args) {
            var target = sender.get_target();
            var navURL = sender.get_navigateUrl();
            window.open(navURL, target)
        }
    </script>

ASPX:

<telerik:RadButton ID="RadButton1" runat="server" ButtonType="LinkButton" Text="click" Target="MyWindow" NavigateUrl="http://www.google.com" OnClientClicked="OnClientClicked" />
