A JavaScript error is thrown when a button with AutoPostback enabled on the client-side is clicked in IE.

Note: The error is thown only when the AutoPostback is enabled in the ClientClicked event handle, but not in ClientClicking.

JavaScript error:

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

RadButton embedded in RadGrid is rendered with rounded corners only when ButtonType="StandardButton" (by default) and UseSubmitBehavior="true" (by default). In all other cases, it has sharp edges:

Code to replicate:

<telerik:RadButton ID="RadButton1" runat="server" Text="Outer button" RenderMode="Lightweight"></telerik:RadButton>

<telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" OnNeedDataSource="RadGrid1_NeedDataSource" RenderMode="Lightweight">
    <MasterTableView AutoGenerateColumns="False">
        <Columns>
            <telerik:GridTemplateColumn HeaderText="TemplateColumn">
                <ItemTemplate>
                    <telerik:RadButton ID="RadButton2" runat="server" Text="StandardSubmit" UseSubmitBehavior="true"></telerik:RadButton>
                    <telerik:RadButton ID="RadButton3" runat="server" Text="StandardNonSubmit" UseSubmitBehavior="false"></telerik:RadButton>
                    <telerik:RadButton ID="RadButton4" runat="server" Text="LinkButton" ButtonType="LinkButton"></telerik:RadButton>
                    <telerik:RadButton ID="RadButton5" runat="server" Text="SkinnedButton" ButtonType="SkinnedButton"></telerik:RadButton>
                    <telerik:RadButton ID="RadButton6" runat="server" Text="ToggleButton" ButtonType="ToggleButton"></telerik:RadButton>
                </ItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

C#

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    (sender as RadGrid).DataSource = Enumerable.Range(1, 6);
}

The appearance of RadRadioButtonList is broken when it is used on the same page with RadButton and the set render mode equals to Auto or Classic.

The bug can be reproduced with the following setup:

No render mode set:        <telerik:RadRadioButtonList ID="RadRadioButtonList3" runat="server">
            <Items>
                <telerik:ButtonListItem Text="AllXxXxX" Value="d" />
                <telerik:ButtonListItem Text="Phone xxxxxxxxx" Value="P" />
                <telerik:ButtonListItem Text="IP/URL xxxxxxxxx" Value="I" />
                <telerik:ButtonListItem Text="General xxxxxxxxx" Value="O" />
            </Items>
        </telerik:RadRadioButtonList>

        <telerik:RadButton runat="server" ID="Button1" Text="Button"/>

RenderMode="Classic":
        <telerik:RadRadioButtonList ID="RadRadioButtonList3" runat="server">
            <Items>
                <telerik:ButtonListItem Text="AllXxXxX" Value="d" />
                <telerik:ButtonListItem Text="Phone xxxxxxxxx" Value="P" />
                <telerik:ButtonListItem Text="IP/URL xxxxxxxxx" Value="I" />
                <telerik:ButtonListItem Text="General xxxxxxxxx" Value="O" />
            </Items>
        </telerik:RadRadioButtonList>

        <telerik:RadButton runat="server" ID="Button1" Text="Button"/>

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.

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=""/>

Add custom Attribute to the RadRadioButtonList control.

By the way its not available as a control in the drop down.

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.

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

You can configure the confirm dialog through a ConfirmText property that defines the confirmation text. The boolean result can be exposed in the arguments of the click event. If there is a RadWindowManager on the same page a radconfirm should be used otherwise - the browser one.

For the time being the functionality can be achieved manually as illustrated in this demo - http://demos.telerik.com/aspnet-ajax/button/examples/confirm/defaultcs.aspx

http://demos.telerik.com/aspnet-ajax/button/examples/radiosandcheckboxes/defaultcs.aspx?skin=Material

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>

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

Improve the SplitButton functionality so it is easier to use. Also provide a way for easier integration of ContextMenu with SplitButton as shown in the following demo: http://demos.telerik.com/aspnet-ajax/button/examples/splitbutton/defaultcs.aspx

RadButton configured as an Image button cannot be clicked if a node from a RadTreeView is selected and EnableDragAndDrop property of the RadTreeView is set to true. The issue is reproducible in iPAD.

For the time being either the EnableDragAndDrop property of the RadTreeView can be set to false or the following JavaScript code can be placed after the declaration of the RadTreeView:

<script type="text/javascript">
                    var $T = Telerik.Web.UI;
                    Telerik.Web.UI.RadTreeView.prototype._onDocumentMouseUp = function (e) {
                        if ($telerik.isTouchDevice) {
                            //this._cancelEvent(e);

                            if (this.longTouchID) {
                                clearTimeout(this.longTouchID);
                                this.longTouchID = 0;
                            }
                            this._treeTouchScroll._dragCanceled = false;
                        }

                        this._detachDragDropEvents();

                        if (!this._dragging) {
                            this._initialDragMousePos = null;
                            this._initialDragNode = null;
                            return;
                        }

                        var sourceNodes = this._sourceDragNodes,
                target = $telerik.getTouchTarget(e);

                        var destinationNode = null;
                        if (target == this._dropClue) {
                            // If the event has hit the DropClue we take the node it is attached to
                            destinationNode = this._dropClue.treeNode;
                        }
                        else {
                            destinationNode = this._extractNodeFromDomElement(target);
                        }

                        if (destinationNode) {
                            if (destinationNode._isDescendantOf(this._initialDragNode) || this._initialDragNode == destinationNode) {
                                this._clearDrag();
                                return;
                            }
                        }

                        var htmlElement = target;

                        var eventArgs = new $T.RadTreeNodeDroppingEventArgs(sourceNodes, destinationNode, htmlElement, this._draggingPosition, e);
                        this.raiseEvent("nodeDropping", eventArgs);
                        if (eventArgs.get_cancel()) {
                            this._clearDrag();
                            return;
                        }

                        htmlElement = eventArgs.get_htmlElement();
                        var command = this._getDropCommand(destinationNode, sourceNodes, htmlElement);

                        if (command.commandName) {
                            eventArgs = new $T.RadTreeNodeDroppedEventArgs(sourceNodes, e);
                            this.raiseEvent("nodeDropped", eventArgs);
                            this._postback(command);
                        }

                        this._clearDrag();
                    };
                </script>

Implementing a fix for the Lightweight RenderMode is likely to cause regressions:
- https://feedback.telerik.com/Project/108/Feedback/Details/166590-fix-the-compatibility-of-radbutton-in-lightweight-with-image-in-cookieless-sessio
- https://feedback.telerik.com/Project/108/Feedback/Details/66505-fix-the-compatibility-of-radbutton-with-custom-image-that-contains-special-symbol

Thus, there are several workarounds:
- use the Classic RenderMode, if possible
- use the script below
- use CSS to set the icon instead of a property (example further down)

JS workaround:
			<telerik:RadButton runat="server" ID="rb1" RenderMode="Lightweight">
				<Icon PrimaryIconUrl="~/Circle_Green_20.png" />
			</telerik:RadButton>
			<telerik:RadPushButton runat="server" ID="rpb1" text="sample text">
				<Icon Url="Circle_Green_20.png" />
			</telerik:RadPushButton>
			<script>
				function repaintButtons() {
					$telerik.$(".RadButton.rbIconButton, .RadButton.rbIconOnly").each(function (index, elem) {
						if (elem && elem.control && elem.control.repaint) {
							elem.control.repaint();
						}
					});
					//uncomment this if you want the method to fire after each partial postback as well
					//Sys.Application.remove_load(repaintButtons);
				}
				Sys.Application.add_load(repaintButtons);
			</script>


CSS workaround:

			<telerik:RadButton runat="server" ID="rb1" RenderMode="Lightweight" CssClass="myCustomIcon" Text="some text">
				<Icon PrimaryIconUrl="Circle_Green_20.png" />
			</telerik:RadButton>
			<style>
				.myCustomIcon .rbPrimaryIcon
				{
					background-image: url(Circle_Green_20.png);
				}
			</style>

The workaround is to override the background image of the button:

CSS:

    <style>
        .RadButton.RadButton_Default.rbLinkButton .rbPrimaryIcon {
            background-image: url("images/Groups (16x16).png");
        }
    </style>

ASPX:

       <telerik:RadButton ID="RadButton1" runat="server" ButtonType="LinkButton" Text="Click" Skin="Default">
            <Icon PrimaryIconUrl="images/myImage (16x16).png" PrimaryIconTop="2" PrimaryIconLeft="2" />
        </telerik:RadButton>

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>
