Sys.ArgumentNullException using RadGrid and RadAjaxPanel with FireFox

Hi all, I get the following error only with Firefox (IE works fine) when I use RadAjaxPanel with the RadGrid inside and RadWindow to edit. It only works for the first time after that I get this error and nothing happens.

Error: [Exception... "'Sys.ArgumentNullException: Sys.ArgumentNullException: Value cannot be null.
Parameter name: handler' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "<unknown>" data: no]

Here is a sample of what I am doing. I am using a MasterPage so this code is in asp:Content...

    
            <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server"> 
        
                    <script type="text/javascript"> 
        
                        function Insert() 
        
                        { 
        
                            window.radopen("Form.aspx", null); 
        
                            return false; 
        
                        } 
        
                        function Update() 
        
                        { 
        
                            window.radopen("Form.aspx", null); 
        
                        } 
        
                        function RefreshGrid(arg) 
        
                        { 
        
                            $find("<%= RadAjaxPanel1.ClientID %>").ajaxRequest(arg); 
        
                        } 
        
                    </script> 
        
                </telerik:RadCodeBlock> 
        
                <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" OnAjaxRequest="RadAjaxPanel1_AjaxRequest"> 
        
                    <telerik:RadGrid ID="RadGrid1" EnableAJAX="false" runat="server" 
        
                    OnItemCommand="RadGrid1_ItemCommand">

                            <Columns> 
        
                                <telerik:GridButtonColumn ButtonType="ImageButton" ImageUrl="Edit.gif" CommandName="InitUpdate" /> 
        
                                <telerik:GridBoundColumn DataField="Name" HeaderText="Name" />

                </telerik:RadAjaxPanel> 
        
                //code behind 
        
                protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e) 
        
                { 
        
                    switch (e.CommandName) 
        
                    { 
        
                        case "InitUpdate": 
        
                            ScriptManager.RegisterStartupScript(this, Page.GetType(), "callback", "Update();", true); 
        
                            break; 
        
                    } 
        
                }

Any help would be greatly appreciated!

Thanks in advance!

Y Axis Formatting

I am creating a Line chart from vb and need to manage the formatting of the Y Axis values. For example, data value is 11,000,000 so I want the Y Axis to display 11 and I will set the AxisLabel.Textblock.Text = "Revenue (Millions)".

I was able to do this with a single series by having two columns in my dataset, one for the real value and one for the display. Then plotting the display and setting the tooltip to show the real value (as not to clutter the chart). However, now I have multiple series (4-8) and this trick no longer works, the value is always assigned to the last column of data regardless of setting the .DataYColumn.

Any suggestions would be helpful.

Tip if you're using html,body,form overflow:hidden

If you're using overflow:hidden in the html, body and form elements when designing you page, be careful because these might affect your RadWindow. RadWindows uses an IFRAME to display page-content and hence another set of html, body and form-tags. In our case we had overflow:hidden for design purposes which carried over causing scollbars to not show in the RadWindows. We solved this by placing the overflow-part in the masterpage itself and not the theme.

Just a tip :)

Localization JavaScript object on custom dialogs.

I am creating custom dialogs using Telerik.Web.UI. DialogDefinition.

In the code behind

    
            String virtualPath  ==  customdialog.ascx  
        
            DialogDefinition cb3ModalDialog = new DialogDefinition(virtualPath, new DialogParameters());  
        
                        cb3ModalDialog.Modal = true;  
        
                        cb3ModalDialog.VisibleTitlebar = true;  
        
                        cb3ModalDialog.VisibleStatusbar = true;  
        
                        cb3ModalDialog.Width = Unit.Pixel(width);  
        
                        cb3ModalDialog.Height = Unit.Pixel(height);  
        
                        cb3ModalDialog.VisibleStatusbar = false;  
        
                        cb3ModalDialog.Title = dialogTitle;  
        
                        this.RadEditorControl.DialogOpener.DialogDefinitions.Add(“CB3ImageManager”, cb3ModalDialog);

And in javascript

    
            var dialogOpener = editor.get_dialogOpener();  
        
            dialogOpener.open('CB3ImageManager', args);

Localization JavaScript object on custom dialogs.

I am creating custom dialogs using Telerik.Web.UI. DialogDefinition.

In the code behind

String virtualPath == customdialog.ascx

DialogDefinition cb3ModalDialog = new DialogDefinition(virtualPath, new DialogParameters());

cb3ModalDialog.Modal = true;

cb3ModalDialog.VisibleTitlebar = true;

cb3ModalDialog.VisibleStatusbar = true;

cb3ModalDialog.Width = Unit.Pixel(width);

cb3ModalDialog.Height = Unit.Pixel(height);

cb3ModalDialog.VisibleStatusbar = false;

cb3ModalDialog.Title = dialogTitle;

this.RadEditorControl.DialogOpener.DialogDefinitions.Add(“CB3ImageManager”, cb3ModalDialog);

And in javascript

var dialogOpener = editor.get_dialogOpener();

dialogOpener.open('CB3ImageManager', args);

Now the questions are

1. Is this is proper way to create custom dialogs? Mainly these dialogs loads faster that the way shown here http://demos.telerik.com/aspnet-ajax/editor/examples/customdialogs/defaultcs.aspx

2. How to make localization JavaScript object available on this ascx dialog so that I can design multilingual custom dialog correctly. In my case if write document.write(localization["Flip"]); it gives error.

3. How can I make server controls like RAD Tab strips localized for custom dialogs?

4. What is the syntax/proper method of adding new localization strings to .resx files.

RadChart. FillType="Image" fading.

I've set FillType = "Image" for the series. When the chart displays it does stretch the images but for some reason it adds fading/gradient at the end of each series. (See the screenshot here ). Is there a way to avoid such behavior?

ASPX:

    
            <telerik:RadChart ID="chartPercent" runat="server" DefaultType="StackedBar100"   
        
                                SeriesOrientation="Horizontal" Width="355px" Height="30px">

Viewstate Tabstrip/Multipage

Hi All,

I have a side with a Tabstrip and a Multipage-Control on a Masterside. On the Multipage are some buttons with underlying ContentPages.
If I click on a button and the pagecontent is loaded also the viewstate of the tabtrip/multipage is lost.

How can I save and restore the viewstate of the TabStrip and Multipage Control?

I would expect if I click on a Tabstrip in comination with an mutlipage control that the viewstate is restored after I click on an multipage button and the pagecontent ist loaded or must I develop something for this senario?

Thanks for help.

Christian
