Blend styling of the AutoHide component?

Please help me to understand how to approach styling the "AutoHide" component of the RadDocking component via Blend.

I have attached 2 screens shots.

The "BaseSS" attachment is the initial view of the Docking component styled up to this point via Blend, and the "AutoHideSS" attachment is the result of selecting "AutoHide" from the pin dropdown menu.

When creating the RadDockingStyle for the RadDocking TargetType / there are many references to telerik:Office_BlackTheme which seems to control the presentation for the AutoHideArea Target Type.

I need to know specifically how I should approach styling <ControlTemplate TargetType="{x:Type telerik:AutoHideArea}"> to match up with the styling I have already completed.

// I am assuming I'm correct in thinking this controls the display shown in "AutoHideSS.png"

When in Blend I do not get the ability to access this template in the "Edit Additional Templates" menu options.

I need to know how to get to this template and if it is not the correct one... if you could point me to the correct template I need to augment.

OR if I would be better served editing the Office_BlackTheme resources in the Telerik base files to match up the hex values or if that is even wise / feasible.
Thanks.
Dan

No visual update after changing category

Hello,

I need to change the category of an appointment by the fly without using the dialog. But the ScheduleView will not update visual before switching the view (e.g. switching to next day and return). How can I force an update?

Here my simple code for changing the categories.

foreach (Appointment app in this.dataModel.Appointments)

{

app.Category = (Category)this.myCategoriesHT["CategoryID"];

}

Appointment sample data crashes Blend designer

I installed RADControls on my system today in order to evaluate the ScheduleView, and I just can't get any sample data into Blend. I ended up creating a simplistic view model that just exposes an ObservableCollection<IAppointment> and the generated sample data still causes the designer to crash with a null reference exception. I then copied the data from the demos into the file, but with the same result, so for now, I'm at a loss.

Thanks for your advice

RadGridView - Data Virtualization Issue

Dear Community,

I have a requirement to populate large volume of data in the grid. I am using RadGridView with data virtualizaiton. I am not using Entity Framework rather using odp.net(oracle provider). Grid populates data using WCF service and while scrolling it is showing desired results. But sorting, grouping , filtering .. none of the features are working. Select All option throws exception! Is there any sample code the same using odp.net or ado.net?

Regards,
Godwin

Controlling portions of the Radsplitbutton

Hi,
I've recently started using Rad controls for WPF in Powerbuilder .NET 12.5

I'm using powerscript to control most of the basic events within my Radbuttons (such as open / close windows, set text labels, etc.)

The issue I'm having is getting full control of the Radsplitbutton.

For example, I currently have a radsplitbutton1 where isOpen = true when the MouseEnter event occurs. I can also use AutoOpenDelay to achieve the same result.

However, I cannot find any way to close the popup. I've tried putting isOpen = false into the MouseLeave and LostFocus events, but it never closes. And there doesn't seem to be anything similar to AutoOpenDelay which will close the popup instead of open it.

Also, the AutoOpenDelay seems to cover the entire button. I'm not sure if there is a way to open the popup ONLY when the mouse is on the drop down arrow?

<ESCAPE> doesn't always exit editing - should it?

I have a grid bound to an Entity Framework-based CollectionViewSource.

For the sake of this example, my columns (left->right) are:

Name - in the database this is required, unique, and non-Null
Serial # - a string

I'm getting an exception when trying to escape editing a new line

Press <click here to add new item>
Type in a name
press <TAB> to advance to serial # column and type in a serial number
press <BACKTAB> to move focus to Name column
delete everything in the Name field that you just entered
Press <ESCAPE> once

My Entity Framework code throws an exception in the Device.Name property setter because it's been passed a Null.

I was under the impression that pressing <ESCAPE> was supposed to exit editing mode and pressing it twice on a new line was supposed to discard it. That (the latter) does happen if I've entered no data in the columns or valid data. If I continue (and ignore the exception), the new row is discarded, but I'm concerned because I don't understand what's happening.

When pressing <ESCAPE>, neither the row or cell validation methods are called, which makes sense.

Why is the RadGridView attempting to update the underlying data when it's about to be discarded?
