I added Exceptions trough RecurrenceRule.Exceptions.Add, but when I use the ToString, the EXDATEs are off by a day.

This is my Exceptions collection,

2/21/2009
2/24/2009
3/7/2009
3/13/2009
3/20/2009
3/27/2009

but the resulting string is

DTSTART:20090213T160000Z
DTEND:20090213T160000Z
RRULE:FREQ=WEEKLY;INTERVAL=1;BYDAY=MO,FR
EXDATE:20090220T160000Z,20090223T160000Z,20090306T160000Z,20090312T160000Z,20090319T160000Z,20090326T160000Z

Adding an appointment to tooltip manager

I don't understand why this isn't working......

protected void RadScheduler1_AppointmentDataBound(object sender, SchedulerEventArgs e)

{

Appointment appt = e.Appointment;

appt.ToolTip = appt.ID.ToString();

RadToolTipManager1.TargetControls.Add(appt.ID.ToString());

}

I keep getting this:

[NullReferenceException: Cannot find a server control with ID=2. If you need to specify a client-side element ID, please set IsClientID to true.]
Telerik.Web.UI.RadToolTipBase.ThrowControlNotFound(String ctrlID) +61 blah blah blah blah blah

I thought I'm supposed to feed RadToolTipManager1.TargetControls.Add the control's ID. I'm guessing that this is not the Appointment ID? How do I grab this?

Sorry for two beginning ASP.NET questions today. This and the other small problem I posted about have me stuck, running in circles. Any assistance would be great.

[Solved] Flickering on frame change

Hi,

In previous (pre-Prometheus) we were using the RadRotator to animate a 24 hour sattelite image sequence.

We need to animate a few images, 130ms between each, with no transitions.

With the new RadRotator, it is superior in every other respect, however we seem to be getting a big white (background) flash between frames. Tested in both IE & FF.

I'm confident we're doing something wrong!!? Hope you can help...

    
                                <telerik:RadRotator runat="server" ID="uxImg" RotatorType="SlideShow" FrameDuration="130" SlideShowAnimation-Duration="0" SlideShowAnimation-Type="None" ScrollDuration="0" Width="640px" Height="521px" PauseOnMouseOver="false" > 
        
                                    <ItemTemplate> 
        
                                        <img src="<%# Container.DataItem %>" style="border:0px;width:640px;height:521px" /> 
        
                                    </ItemTemplate> 
        
                                </telerik:RadRotator>

Thanks,
Laurie

GetRadWindow().Close() cause unspecified error

Hello sir

I have this section in my aspx page:

<telerik:RadWindowManager ID="RadWindowManager3" runat="server" DestroyOnClose="true">
<Windows>
<telerik:RadWindow ID="wndStatus" runat="server" Width="750px" Height="550" Skin="Vista"
    Behavior="Move,Close,Resize" Title="הודעת מערכת" Modal="true" DestroyOnClose="true"
    KeepInScreenBounds="true" ReloadOnShow="true" VisibleStatusBar="false">
</telerik:RadWindow>
</Windows>
</telerik:RadWindowManager>

When the window opens, it has a click event which does the following:

<script type="text/javascript">
function CloseAndRebind(rebind)
{
    GetRadWindow().Close();
}

function GetRadWindow()
{
    var oWindow = null;
    if (window.radWindow)
        oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog
    else if (window.frameElement.radWindow)
        oWindow = window.frameElement.radWindow;//IE (and Moz az well)
    return oWindow;
}
</script>

The problem:
When I click the button, the command GetRadWindow().Close();   bring this message:
A Runtime Error has occurred.
Line 5959 Error: Unspecified error.

In development mode, the debugger goes to ScriptResource.axd and stop at the following line:

Var offsetl = w.screenleft – top.screenleft – top.document.documentElement.scrollleft + 2;

Can you help me?

Init and Viewstate

As a quick test I made a page with a regular ASP.NET dropdown and added an event handler to its Init event. Then in that event handler I created a large array of strings and used DataSource and DataBind() to populate the dropdown with the data. When I do this the Viewstate of the page is nearly empty.

But when I do the same thing with a RadComboBox the Viewstate is huge. Is there any way to do a normal data bind with the RadComboBox before Viewstate tracking starts and have it work the same way as the normal ASP.NET controls (preferably without disabling Viewstate on the entire control)?

CSS For Group

I am using the menu control to create a drop down button. Essentially it is a single root level item that drops down a selection list. I have the main button taking my css, as well as the individual menu items but cannot figur out how to set the css for the group of items. In other words, the menu displays but there is no background behind the items.

    
            <telerik:RadMenu ID="RadMenu1" runat="server" Skin="" ClickToOpen="true"> 
        
                                <DefaultGroupSettings ExpandDirection="down" /> 
        
                                <Items> 
        
                                    <telerik:RadMenuItem Text="Override Status"  GroupSettings-ExpandDirection="Down" CssClass="CommandButton" > 
        
                                        <Items> 
        
                                            <telerik:RadMenuItem Text="test"  CssClass="DropMenuButton"></telerik:RadMenuItem> 
        
                                            <telerik:RadMenuItem Text="test2" CssClass="DropMenuButton"></telerik:RadMenuItem> 
        
                                            <telerik:RadMenuItem Text="test3" CssClass="DropMenuButton"></telerik:RadMenuItem> 
        
                                        </Items> 
        
                                    </telerik:RadMenuItem> 
        
                                </Items> 
        
                            </telerik:RadMenu>

in a related issue...i cannot get the menu to expand down....so it behaves like a "drop up" button. Any help would be appreciated.

Hi!

I have a problem when manuelly setting DataSource of my Grid. I habe a Tabstrip where the first tabs are used to add an remove articles to an articlelist, the last tab should display the ordered Articles in the Grid. The Problem is when i click the Tab(Article Summary) the datasource of the grid changes properly but the Grid still displays the old items.

here are my code snippets

DataBinding

    
            SummaryGrid.DataSource = String.Empty; 
        
                        List<PriceRow> pricelist = GetItems(); 
        
                        if (pricelist != null) 
        
                            SummaryGrid.DataSource = pricelist;

I hope somebody can help me with this issue.
