To whom it may concern

I have a radwindow that is launched with javascript. It works 100% on my development machine (Vista & IE8). On a machine with Windows XP SP3 with IE8 though, there are some issues.

The radwindow loads okay. Some of the controls within the radwindow though, do not.

The Combobox does not seem to load correctly when the page loads. When I minimize and then maximise the browser window, the combobox works, but still seems a bit buggy.

Are there known issues with comboboxes contained in a radwindow on IE8 with XP?

Regards

Hanno

[Solved] AppointmentDataBound error after OnAppointmentInsert

Hi,

I'm using AppointmentDataBound to apply my own cssClasses to scheduler appointments based on their type, status and colour. The type, status and colour are fields I store in the appointments record in my SQL table.

This all works really well and I get icons based on the appointment type and colours based on their status etc...

My problem occurs after I insert a new appointment. I get an error 'object variable or with block variable not set' in the AppointmentDataBound code. I think this is because the dataitem is not available at this point.

This is really stumping me and I just can't seem to get around it. Here's the code :-

    
            Protected Sub Calendar_AppointmentDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.SchedulerEventArgs) Handles Calendar.AppointmentDataBound  
        
                    'Grab details about the appointments appearance  
        
                    Dim apptComputer As String = e.Appointment.DataItem("computer_name").ToString  
        
                    Dim apptProject As String = e.Appointment.DataItem("project_name").ToString  
        
                    Dim apptRelease As String = e.Appointment.DataItem("release_name").ToString  
        
                    Dim apptType As Integer = e.Appointment.DataItem("appointment_type").ToString  
        
                    Dim apptColour As String = "White" 
        
                    Dim apptStatus As Integer = e.Appointment.DataItem("Status").ToString  
        
                    Dim strStatus As String = "Scheduled" 
        
                    Dim strCSSClass As String = "rsCategoryBlue" 
        
                    e.Appointment.Subject = "Project: " & apptProject & Chr(13) & "Release: " & apptRelease & Chr(13) & "Computer: " & apptComputer

                    Select Case apptStatus  
        
                        Case 1 'Scheduled

                End Sub

After the insert code runs the databound code is called again and any reference to e.appointment.dataitem or even e.appointment.id returns the 'object variable or with block variable not set' error.

Accessing Data From Client Side

Dear Sir,
This Example is the same you have in the online documentation, but it's not working.
please i need this functionality to be able to access the data from the client side.

    
            <telerik:RadListView ID="RadListView1" runat="server" ClientDataKeyNames="ID">  
        
            </telerik:RadListView> 
        
            <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">  
        
            <script type="text/javascript">  
        
            function GetClientDataKeyValueForFirstItem()   
        
            {  
        
               var clientDataKeyValues = $find("<%= RadListView1.ClientID %>").get_clientDataKeyValue();  
        
               var firstItemKeyValue = clientDataKeyValues[0]["ID"];  
        
            }  
        
            </script> 
        
            </telerik:RadCodeBlock>

parentheses for negatives

Hi ,
How could i set parentheses for negatives using boundcolumns without currency symbol something like this

(1,980.70)

actually i have this dataformatstring , and its cool 'cause completes the decimal position with #.00 always

    
            <telerik:GridBoundColumn    DataField="Noviembre" Aggregate="Sum" HeaderStyle-HorizontalAlign="Right" DataFormatString="{0:N2}" DataType="System.Decimal" 
        
                                                                                        FooterAggregateFormatString="{0:N2}" FooterStyle-Font-Bold="true"> 
        
                                                                                         <HeaderStyle HorizontalAlign="Right" /> 
        
                                                                                         <ItemStyle HorizontalAlign="Right" /> 
        
                                                                                 <FooterStyle HorizontalAlign="Right" /> 
        
                                                            </telerik:GridBoundColumn>

wih this code and setting the dataformatstring={"0:C"} parentheses works but whit the currency symbol

    
            CultureInfo ci = new CultureInfo("es-PE"); 
        
            ci.NumberFormat.CurrencyNegativePattern = 14; 
        
            System.Threading.Thread.CurrentThread.CurrentCulture = ci;

i hope you can help me, thanks

Regards
Gino

Problem with OnClientLoad

Hello Everybody,

I have problem with OnClienLoad property. We create dynamicly radeditor code behind like this:

    
             Dim editor As Control = CreateDhtmlEditor("editor")  
        
             Label1.Controls.Add(editor) 'Add control to label  
        
             'Find RadEditor and add Ajax to component  
        
             Dim RadEd As Telerik.WebControls.RadEditor = CType(Page.FindControl("editor"),Telerik.WebControls.RadEditor)  
        
            RadAjaxManager1.AjaxSettings.AddAjaxSetting(btnOpenTemplate, CType(RadEd, Telerik.WebControls.RadEditor), AjaxLoadingPanel1)  
        
             RadAjaxManager1.AjaxSettings.AddAjaxSetting(btnOpenTemplate, CType(RadEd, Telerik.WebControls.RadEditor), AjaxLoadingPanel1)  
        
            'add client side event  
        
            RadEd.OnClientLoad="OnClientLoad"

Basicly this is how we create Editor to Webpage. I have written my onLoadevent into page.aspx file. This is written onload event on codebehind

    
             function OnClienLoad(editor)  
        
            {  
        
               alert('Editor');  
        
            }

Every time i get following error message:
Exception on excetuing Client event onclientload error:'OnClientLoad' is undifined.

Please some tell what I am doing Wrong. We are using RadEditor 7.12.

GridBoundColumn to GridDropDownColumn

I have a RadGrid with AutoGenerated GridBoundColumns.

This works great, however i am trying to make one of these columns a GridDropDownColumn from the ColumnCreated() event. I can't find any examples of this anywhere. This post: http://www.telerik.com/help/aspnet/grid/grdcustomizeconfiguregriddropdowncolumn.html is not helping me very much being that all my columns are GridBoundColumns, i have no GridDropDownColumns and (GridDropDownListColumnEditor)(editMan.GetColumnEditor()) fails every time.

Can someone tell me how to set a GridBoundColumn as a GridDropDownColumn?

Thanks,

Duncan

Chart xAxis

I am using a bar chart with 3 stacked bars and a line, so 4 series total. The xAxis label is going right through the xAxis, i really need to move the xAxis label down about 50px so it sets below the xAxis.

sample if ______________________ is the xAxis and 12345 is the label.

1

2

__3_____________________________________

4

5

I am setting the following values.

                                radChart.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = 45;         
                        radChart.PlotArea.XAxis.Appearance.TextAppearance.TextProperties.Color = System.Drawing.Color.Black;         
                        radChart.PlotArea.XAxis.AxisLabel.Appearance.Position.AlignedPosition = Telerik.Charting.Styles.AlignedPositions.Bottom;         
                        radChart.PlotArea.XAxis.AxisLabel.Appearance.Position.Auto = false;         
                        radChart.PlotArea.XAxis.AxisLabel.Appearance.Position.X = 200;         
                        radChart.PlotArea.XAxis.AxisLabel.Appearance.Position.Y = 125;         

Ideas?

RadAjaxManager configuration in Custom Control

I have created custom control for RadRotator, the functionality of control is like http://demos.telerik.com/aspnet-ajax/rotator/examples/gallery/defaultcs.aspx. I am using RadAjaxManager to show the details section on click of the strip image. But its refreshing the whole page, instead of just refreshing the details section.

It will be highly appreciated if you could provide me the steps or sample code for configuring the RadAjaxManager in custom controls.

I am getting folowing error on the page

    
            Message: Sys.ArgumentNullException: Value cannot be null.  
        
            Parameter name: panelsCreated[2]

Thanks
