We are rendering the sliders dynamically in datalist as follow:

    
            <asp:DataList ID="dlIndicator" runat="server" CellPadding="0" CellSpacing="4" RepeatColumns="3" RepeatDirection="Horizontal"> 
        
                        <ItemTemplate> 
        
                            <table cellpadding="0" cellspacing="2" border="0"> 
        
                                <tr><td>&nbsp;</td><td><%#Eval("Name")%></td><td>&nbsp;</td></tr> 
        
                                <tr> 
        
                                    <td valign="top"> 
        
                                        <asp:CheckBox ID="chkIndicator" runat="server" /><asp:HiddenField ID="hdnIndicatorDomain" 
        
                                            runat="server" Value='<%#Eval("IndicatorID")%>' /><asp:HiddenField ID="hdnIndicatorValue" runat="server"  Value='<%#Eval("Value_")%>'/> 
        
                                    </td> 
        
                                    <td> 
        
                                        <telerik:RadSlider ID="rslIndicator" runat="server" MinimumValue="0" MaximumValue="100" 
        
                                            Value="50" OnClientValueChange="HandleValueChange" OnClientLoaded="HandleValueChange" 
        
                                            Skin="Vista" SmallChange="5" Width="100px" /> 
        
                                    </td> 
        
                                    <td> 
        
                                        <asp:Label ID="lblIndicator" runat="server"></asp:Label>% 
        
                                    </td> 
        
                                </tr> 
        
                            </table> 
        
                        </ItemTemplate> 
        
                    </asp:DataList>

    
            <script type="text/javascript" defer="defer"> 
        
                            function HandleValueChange(sender, eventArgs) 
        
                            { 
        
                                var spnid = sender.get_id().replace("rslIndicator","lblIndicator") 
        
                                document.getElementById(spnid).innerHTML = sender.get_value(); 
        
                            } 
        
                </script>

The issue is.. the sliders working fine in IE7.. but not in IE8.
In IE8, when we drag handle in one slider, it automatically drags handles on other sliders.

We are using telerik version : 2008.03.1314.35

Editor doesn't work in Firefox when it is loaded via Ajax in a multiview

Hi Telerik!
I have a page with a multiview. The views are loaded using Ajax. The editor is located in the second view. In Firefox, when I click on "View 2", I am unable to type in the editor 50% of the time. None of the buttons and dropdowns work either. The editor will stop working completely if I switch between "View 1" and "View 2" a couple of times.

Below is the code sample that can reproduce the problem. I am using Firefox 3.0.11 and version 2009.1.527.35 of Telerik.Web.UI.dll.

Filtering Grid on ";" Character Causes Error

Hello,

When entering a ";" character in the basic "contains" filter for a text column causes an "IndexOutOfRange" exception.
Below is the stack trace:

System.IndexOutOfRangeException: Index was outside the bounds of the array.
at Telerik.Web.UI.RadGrid.RaisePostBackEvent(String eventArgument)
at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument)
at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

We have been able to duplicate this issue on the RadGrid demo.
Is there a work around? Or, some way to remove this character from a user's filtering.

Thanks,
Jon

The System Cannot Find the Path Specified

We are getting this warning in the Event Viewer on a Production application (a server without a Telerik installation).

The server was unable to add the virtual root '/telerik/RadControlsQ2_2007_NET2' for the directory 'C:\Program Files\Telerik\RadControls for ASP.NET Q2 2007\NET2' due to the following error: The system cannot find the path specified.

The application has crashed a few times and an IIS reset brings the application back up. Any ideas on how to remove this warning without an installation of Telerik on the server?

[Solved] Listbox Client-Side DataBinding

Does the listbox support client-side databinding? I would like to create a list of items from the server-side and populate the listbox in the callback function of a page method call. Is this possible? I could not find anything in the documentation or demos for doing something like this.

[Solved] Export As String not Int

Have a grid whit following column:

    
            <telerik:GridBoundColumn DataField="ArticleCode" UniqueName="ArticleCode" HeaderText="ArtikelID" ReadOnly="true" DataType="System.String"></telerik:GridBoundColumn>

In this column I insert values tha look like "001", "002" etc

But when I export it to Excel it formats the column to Integer values so it only displays 1,2 etc

How do I make the Excel sheet accept the value as a string and not an Integer?

    
            protected void ButtonExportToExcel_Click(object sender, EventArgs e)  
        
            {  
        
               RadGridMembers.ExportSettings.ExportOnlyData = false;  
        
               RadGridMembers.ExportSettings.IgnorePaging = true;  
        
               RadGridMembers.ExportSettings.OpenInNewWindow = true;  
        
               RadGridMembers.Page.Response.ClearHeaders();  
        
               RadGridMembers.Page.Response.Cache.SetCacheability(HttpCacheability.Private);  
        
               RadGridMembers.MasterTableView.ExportToExcel();
