Hi,

I have a RadCombobox containing a RadTreeView ItemTemplate. Everything works fine when I use it in a web page. However, when I move it to a user control, I wasn't able to access to the TreeView client object anymore. Here is how I try to get checked tree nodes displayed in RadCombox's text:

    
                function OnDropDownClosed(sender, eventArgs)  
        
                {  
        
                    var treeView = $find('<%# RadComboBox1.Items[0].FindControl("RadTreeView1").ClientID %>');  
        
                    var nodes = treeView.get_checkedNodes();  
        
                    var str = '';  
        
                    for (var i=0; i<nodes.length;i++)  
        
                    {  
        
                        str += ', ' + nodes[i].get_text();  
        
                    }  
        
                    sender.set_text(str);  
        
                }

The error message I got was "'null' is null or not an object." Please help. Thanks,

RadGrid end-user manual?

Do you happen to have an end-user manual for your RadGrid? More specifically, I am looking to provide the end-users of my web app with a help page on how the filters work in the grid. During initial testing, some of my end users were confused as to how the filters work and what all the filtering options mean. If you do not have an end-user manual already, please consider creating one. Thank you very much.

Problem with VisibleDuringInit=false

There is a problem With the RadSplitter for ASP.NET AJAX in RadControls for ASP.NET AJAX Q3 2008 in Internet Explorer (6 and 7) when the VisibleDuringInit property is set to "false" - the content of the RadPanes remains hidden even after the RadSplitter has finished its initialization. The problem does not exist in FireFox, Safari, Opera, and Chrome.

Fix for the problem:

Assign a handler for the OnClientLoaded event of the RadSplitter:

    
            <telerik:RadSplitter ID="RadSplitter1" runat="server" VisibleDuringInit="false"   
        
                OnClientLoaded="OnClientLoaded"

and execute the following code in it:

    
            <script type="text/javascript">  
        
            function OnClientLoaded(sender, args)  
        
            {         
        
                sender.get_element().style.visibility = 'inherit';  
        
            }  
        
            </script>

The problem is due to a bug in IE which fails to re-render its child elements when a parent's CSS visibility setting is changed.
Essentially the workaround forces IE to re-render these elements.

Screenshots of the page showing the problem and with the applied fix are attached to this thread.

Please accept our sincere appologies for the problem. The omission is clearly on our end, and we are deeply sorry for the frustration caused. This thread provides a workaround, that we believe is fairly easy and in addition to this, should you need a fixed Telerik.Web.UI build, please contact us with a support message, and we will send you a custom build DLL as well.

Note: This topic is for information purposes only and is locked. If there are any additional issues related to this problem, please open a support ticket or use the forums.

Unable to modify legend marker

RadChart 2008 Q2.

I build a radchart programatticaly and first setup the styles:

chart.Skin = "";
chart.Legend.Marker.Appearance.Border.Visible = false;
chart.Legend.Marker.Appearance.Border.Color = Color.Black;
chart.Legend.Marker.Appearance.Figure = "Rectangle";
chart.AddChartSeries(series)

On Render, none of the legend modifications hold, ie the markers are round, the border is light blue. Is there something I need to set to get this to override the defaults?

Thanks,
Jason

onclientPasteHTML

Hi
When I'm using the "Paste" command, the "onclientPasteHtml" event is not launched. I have to call the PasteAsPlainText or PasteFromWord to make it work, but PasteFromWord automatically add a linefeed before my text is copied. In my function called from the event, I'm doing a PasteHtml("blabla"). I tried to put a space before, like PasteHtml(" blabla") but I still have the line feed.

What can I do to launch the onclientPasteHtml event with the Paste command or to use the PasteFromWord command without the line feed ?

Thanx
