Hi, I have a problem with slider events not working on Opera browser.

1. PageLoad event is not being recognized by Opera. Here is my code.

    
            function pageLoad(sender, args) {  
        
                   var status = Sys.WebForms.PageRequestManager.getInstance().get_isInAsyncPostBack();  
        
                   if (!status) {  
        
                       HidePanels();  
        
                   }  
        
            }

2. None of the get/set methods are working in Opera.
Ex:

    
            slider.get_isSelectionRangeEnabled()  
        
            slider.set_selectionStart(newValue);  
        
            slider.set_selectionEnd

Any help is appreciated.

thanks

Hello Kalyani Mantripragada,

I tested the following code and it works under latest Opera version(10.50):

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

<script type="text/javascript">

function pageLoad(sender, args) {

alert("pageLoad");

var status = Sys.WebForms.PageRequestManager.getInstance().get_isInAsyncPostBack();

if (!status) {

alert("status is" + status);

}

</script>

</head>

<body>

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

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

<div>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<ContentTemplate>

<asp:Button ID="btnPostback" Text="Postback" runat="server" />

</ContentTemplate>

</asp:UpdatePanel>

</div>

</form>

</body>

</html>

My suggestion is to use AJAX's Client Life-Cycle Events. More about them is available here: http://msdn.microsoft.com/en-us/library/bb386417.aspx

I was also unable to find a problem related to the RadSlider's methods. Here is the code which I tested under Opera 10.50:

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

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

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

<script type="text/javascript">

function MyPageLoad() {

var slider1 = $find("RadSlider1");

alert("slider1 isSelectionRangeEnabled:" + slider1.get_isSelectionRangeEnabled());

var slider2 = $find("RadSlider2");

alert("slider2 isSelectionRangeEnabled:" + slider2.get_isSelectionRangeEnabled());

var selectionStart = slider2.get_selectionStart();

var selectionEnd = slider2.get_selectionEnd();

alert("slider2 selectionStart is:" + selectionStart + ";selectionEnd is:" + selectionEnd);

//Set new values;

slider2.set_selectionStart(4);

slider2.set_selectionEnd(6);

selectionStart = slider2.get_selectionStart();

selectionEnd = slider2.get_selectionEnd();

alert("slider2 new selectionStart is:" + selectionStart + ";new selectionEnd is:" + selectionEnd);

}

Sys.Application.add_load(MyPageLoad);

</script>

<div>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<ContentTemplate>

<asp:Button ID="btnPostback" Text="Postback" runat="server" />

<telerik:RadSlider ID="RadSlider1" runat="server" IsSelectionRangeEnabled="false" Value="0"

MinimumValue="0" MaximumValue="10"></telerik:RadSlider>

<telerik:RadSlider ID="RadSlider2" runat="server" IsSelectionRangeEnabled="true"

MinimumValue="0" MaximumValue="10"

SelectionStart="0" SelectionEnd="10">

</telerik:RadSlider>
