Calendar coming up with grey dates

I have a WPF view that have 5 calendar controls on it. When the view is first loaded all of the dates are grey in color, but when the mouse hovers over each date they switch to black. When navigating months all of the dates turn black and everything is fine at that point, it is just that inital load that is an issue? is there a default setting or a way to set that style so they start out black to begin with, not just on mouse over?

Results from stored procedure not matching what is in view model

Hi - I'm not sure where to post this, if this isn't the right place please let me know.

We have an application using WPF/RIA services and an MVVM framework. We called stored procedures in SQL to get data through our model.

I've found an issue that I can't explain and so don't know how to fix. What we are seeing is that the results being returned by our stored procedures when I run them directly in SQL Server Management Studio don't match what I see in the application. In this case, we are displaying the data in aRadGridView, but I can look at the data when it is returned in the context and it's wrong there too.

The problem is that not all the records I expect to see are there. For example, in one case my stored procedure run directly from SMS returns 251 rows, the grid in our app is displaying 20 of them, and I see those 20 rows in the results when I look running in Debug.

Are there settings that limit the amount of rows that are returned? In some cases, there are a lot of rows, but what we've found in the past is that the app times out. I'm not sure where else to look.

Any help would be appreciated!

Parent/Child On WPF Gantt Chart not working

Since I don't see any complaints about this feature, I assume that there is something fundamental not mentioned in any documentation or video that somehow activates this functionality, because following the video and online documentation (i.e. the vary basic examples) I NEVER see the parent child setup (expanders and indentation). Any push in the right direction or information about the latest on where the development of the WPF version of this control is would be greatly appreciated. So far, it seems unusable, but I cannot believe that since this control is in released status for WPF; listed as new. First tried it in our application, but then thought the complexities were causing issues. But now I see that the basic application in its own WPF window/project/solution fails as well.

This was built with the just downloaded Q2 2013 6/11 version. No change from Q3 2012 1017 internal build that we were running.

Very frustrating.

Cancel Edit and Delete Behavior

I have read that after inserting a new row in edit mode, it takes two Escape presses to allow the row to be deleted. Why does it take two presses, what is the underlying functionality that requires this, and is there a way to configure it so the user only has to press once?

Thanks in advance,
Steve

URGENT - Add blank to GridViewComboBoxColumn?

Hello,

PLEASE SOMEONE ANSWER THIS ASAP.

I bind a GridViewComboBoxColumn to a list of objects, now problem at all with anything there including setting to currently selected value.
I need to give the user the option of selecting blank item as that field can be empty. Need to put a blank item into the GridViewComboBoxColumn at the top of the list.

HOW CAN I DO THAT? Standard combobox is easy and I don't want to use those in a CellEditTemplate either as using that will change the ViewModel(s) and bindings quite a bit.

Thanks

Changing appointment start/end not reflected on UI?

Hi all

I have a custom appointment, of which I am modifying both Start and End programmatically if a command is fired. The problem is that setting those properties doesn't result in the UI being updated: The appointment still shows the old start / end boundaries until I change the view. For now, I employed a dirty hack by removing and reinserting the modified item, but this is obviously a horrible workaround.

Thanks for your advice
Philipp

Here's my code:

public class CalendarItemViewModel : AppointmentBase

{

public LaborTrackingSession Model { get; private set; }

public override DateTime Start

{

get { return Model.StartTime.DateTime; }

set

{

Model.StartTime = value;

OnPropertyChanged(() => Start);

}

public override DateTime End
