Hi,

I got a problem with RadAlert on IE6 with Telerik 2008 Q2 (2008.2.826.20).
IE6 freezes after clicking on the OK button.

Here is the code :

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="RadAlertBug._Default" %> 
        
            <html xmlns="http://www.w3.org/1999/xhtml"> 
        
            <head runat="server"> 
        
                <title>RadAlert bug</title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                <asp:ScriptManager ID="sm" runat="server" /> 
        
                <telerik:RadWindowManager ID="RadWindowManager1" runat="server"> 
        
                 </telerik:RadWindowManager> 
        
                <telerik:radajaxloadingpanel id="GceAjaxWorkingPanelLoading" runat="server" transparency="20"> 
        
                    <table style="width: 100%; height: 100%; background-color: white;"> 
        
                        <tr> 
        
                            <td align="center" valign="middle" style="color:#666666"> 
        
                                Loading...<br /> 
        
                                <img alt="Chargement..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading5.gif") %>' style="border: 0px;" /> 
        
                            </td> 
        
                        </tr> 
        
                    </table> 
        
                </telerik:radajaxloadingpanel> 
        
                <telerik:radajaxpanel id="RadAjaxPanel" runat="server" loadingpanelid="GceAjaxWorkingPanelLoading"> 
        
                    <asp:Button ID="OpenRadAlertButton" runat="server" onclick="OpenRadAlertButton_Click" Text="Open RadAlert" /> 
        
                </telerik:radajaxpanel> 
        
                </form> 
        
            </body> 
        
            </html>

    
            using System; 
        
            namespace RadAlertBug 
        
            { 
        
                public partial class _Default : System.Web.UI.Page 
        
                { 
        
                    protected void Page_Load(object sender, EventArgs e) 
        
                    { 
        
                    } 
        
                    protected void OpenRadAlertButton_Click(object sender, EventArgs e) 
        
                    { 
        
                        if (RadAjaxPanel.IsAjaxRequest) 
        
                        { 
        
                            RadAjaxPanel.ResponseScripts.Add("radalert(\"Message\", 300, 100, \"Title\");"); 
        
                        } 
        
                    } 
        
                } 
        
            }

Here is the scenario :

- Click on the RadAlert button (-> opens the popup)
- On the alert popup, click on the message then on the button (-> closes the alert)
- Click again on the RadAlert button (-> opens the popup)
- On the alert popup, click again on the message then on the button (-> IE6 freezes !!)

Hello B,

This problem is fixed in more recent versions of the control. I strongly recommend to consider upgrading, but if this is not possible at the moment, the only workaround that I can suggest is to modify the alert template and set the unselectable property to on for the div that wraps the text.
e.g.

<telerik:RadWindowManager DestroyOnClose="true" ID="RadWindowManager1" runat="server">

<AlertTemplate>

<div class="windowpopup radalert">

<div class="dialogtext" unselectable="on">

{1}

</div>

<div>

<a onclick="$find('{0}').close();"

class="radwindowbutton" href="javascript:void(0);">

<span class="outerspan">

<span class="innerspan">##LOC[OK]##</span>

</span>

</a>

</div>

</AlertTemplate>

</telerik:RadWindowManager>

Hello Bruno,

Unfortunately the workaround that I suggested can be applied to the text only - that is why I suggested to consider upgrading to a recent version of the control. The main reason for the problem is a bug in IE and as I said we managed to find a workaround for it from our side, but for this we've had to change some of RadWindow's code, so the only way to avoid that problem is to upgrade.

Kind regards,
