Greetings-
I am trying to tailor a RadComboBox to look behave visually like our mock ups. I have achieved about 80% of what I am looking to do, but I could use some assistance with the last part...as I am not even sure it is possible to do.


I would like the foreground color or font face to be white on the combo box, but have the list below it be black. The reason is that we have a dark gradient for the RadComboBox style, but a white background for the dropdown list. Is there any way to achieve this through the new version of the controls in Expression Blend or through XAML?

I have pasted my XAML for MainWindow and AppResources so you can see where I am at thus far.

Your help would be much appreciated.
Regards...

The custom toolip example has a TargetType and no key so it overrides all tooltips. How can I just target the Appointment with a custom toolip?

Thanks,

Hi,
I get an exception when i add theses lines in my xaml :

<telerik:ChartArea.AxisX>

    <telerik:AxisX x:Uid="telerik:AxisX_2"

            AxisLabelsVisibility="Collapsed"

            MajorTicksVisibility="Collapsed"

            MinorTicksVisibility="Collapsed" />

</telerik:ChartArea.AxisX>

If remove them the chart is correctly displayed. Is it the right manner to hide all the ticks ?
I want the lightest graph possible : only the bar with the value number in it, no legend, no title, no tick, nothing else,...

Any help ?

Here are the complete files:

The Xaml:

and the code of the ViewModel:

public class MainViewModel : ViewModelBase

{

    public MainViewModel()

    {

        this.Items = new List<Item>()

    {

        new Item() 

        { 

            Level = 1, 

            Text ="AAAA", 

            StatusGroup = new List<StatusPerformance>()

            {

                new StatusPerformance("Success", new List<Performance>() 

                {

                    new Performance() { Name="TMI", Count=76},

                    new Performance() { Name="TXT", Count=39}

                }),

                new StatusPerformance("Misrecognition", new List<Performance>() 

                {

                    new Performance() { Name="TMI", Count=15},

Hello,

How can i make the DataFormComboBoxField editable (also with autocomplete) ?

i have resolved :D close it please

I have a data class, Category, which has a property Children. This hierarchy, from a root Category node is bound to a TreeView. Category.Name is what displays for the Category. TreeView currently works fine.

What I need to figure out how to do is raise an edit event when the user makes a modification of the display value. I do not want to actually have anything edit the underlying bound value, until I do it myself.

I have tried with and without an EditItemTemplate. In the RadTreeView.Edited event, Source is set to the Category instance itself. OriginalSource is set to the RadTreeViewItem. NewText and OldText are both null (deprecated.) OldValue and NewValue are set to teh Category instance itself. And the Category.Name property has been edited. OldValue.Name and NewValue.Name are both the new value. Of course. Since it's set to the instance itself, there's no way to distuinguish between the before and after states.

What the heck can I do here? I thought I'd just use an EditItemTemplate, with a custom TextBox, in order to capture the new value, and set the Binding.Mode of the HierarchalDataTemplate to OneWay, to prevent it from being changed. However, now I have no way in the Edited event to retrieve the new value. I can't find the TextBox of the EditItemTemplate anywhere underneath RadTreeViewItem, and the OldValue and NewValue are of course still set to the Category itself (which is no longer altered, at least.)

Help?

Hi,

We are hosting RadScheduleView inside a ActiveX control on a win32 application using "HWNDSource" mechanism. The RadScheduleView UI appears properly but we are facing problems with the modal dialogs like EditAppointmentDialog, EditRecurrenceDialog, DeleteConfirmationDialog etc.,

All these dialogs appears correctly on the RadScheduleView and blocks any operation on RadScheduleView as expected. But when we switch to other application and come back to ScheduleView application all these dialogs does not come to focus by default (ie., does not appear on RadScheduleView). These popped up dialogs remain behind and need to select manually (using Alt-tab) to bring them front.

Any help/idea to solve this issue is highly appreciated.
