Hello Dan,

I tried reproducing this problem with the following markup:

<telerik:RadButton runat="server" ID="RadBUtton1" Skin="MetroTouch" RenderMode="Lightweight" Text="some text" OnClientClicked="function(){alert()}"></telerik:RadButton>

I am also attaching a short video from my test so you can confirm if I am missing something, because I could not reproduce a problem.

Hi,

We have the same problem with the latest Telerik!

But only when the button is inside an UpdatePanel and only in the new Microsoft Edge browser!!!

Code sample:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="button.aspx.vb" Inherits="TestaTredjepartWeb.button" %>

<!DOCTYPE html>

<html>

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="s" runat="server">

</asp:ScriptManager>

<div>

<asp:UpdatePanel ID="up" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">

<ContentTemplate>

<telerik:RadButton ID="btn" runat="server" Text="Click me" RenderMode="Lightweight"></telerik:RadButton>

<br />

<asp:Label ID="lbl" runat="server"></asp:Label>

</ContentTemplate>

</asp:UpdatePanel>

</div>

</form>

</body>

</html>

Code behind:

Public Class button

Inherits System.Web.UI.Page

Private _bButtonClicked As Boolean = False

Private Sub btn_Click(sender As Object, e As EventArgs) Handles btn.Click

_bButtonClicked = True

End Sub

Private Sub button_PreRender(sender As Object, e As EventArgs) Handles Me.PreRender

If _bButtonClicked Then

lbl.Text = "Button was clicked"

Else

lbl.Text = "Button was NOT clicked"

End If

End Sub

End Class

In Microsoft Edge, when clicking on the text, the click event does not happen.

In other browsers it works fine!

Regards
Andreas

Hello,

This is an issue with an ajaxified RadButton in lightweight render mode when clicking its text and the used browser is Chrome/Edge browser.The issue will be fixed for the Q1 2016 release and the next internal build.

You can find more information as well as possible workaround in this sticky note (http://www.telerik.com/forums/the-server-side-onclick-event-is-not-raised-when-clicking-on-the-button-text-(lightweight-rendermode-chrome-browser-q3-2015-sp1-release)) or this feedback item (http://feedback.telerik.com/Project/108/Feedback/Details/176156).

Apologize for the caused inconvenience.
