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

{

get { return Model.EndTime.HasValue ? Model.EndTime.Value.DateTime : SystemTime.Now().DateTime; }

set

{

Model.EndTime = value;

OnPropertyChanged(() => End);

}

...

}

RadGridView RadDateTimePicker Time selector default date

I am using a RadGridView, which has a column whose data template is a RadDateTimePicker. The value for this column is data bound (MVVM) to a nullable date time property. So when I create a new row, the initial value is null and then the user will set the value for the date time using the picker (See xaml code below).

Now, I am setting the SelectableStartDate property for the picker to tomorrow since i do no want the user to be able to select a date as today or in the past. Assuming I just added a new row with a null/empty date time value and just clicked on the cell to open the date time picker, if I select the time first and not the date, it is firing the binding with the date as today's date with the selected time, even though the Selectable date is set to start from tomorrow. I tried using some properties on the picker itself to try and change that but could not make it work.

Any suggestions on this?

<telerik:GridViewDataColumn Header="Start Date"

Width="135"

Name="StartDateColumn"

EditTriggers="CurrentCellClick"

DataFormatString="{}{0:M/d/yyyy hh:mm tt}"

CellStyleSelector="{StaticResource startDateCellStyleSelector}"

DataMemberBinding="{Binding StartDate}">

<telerik:GridViewDataColumn.CellEditTemplate>

<DataTemplate>

<telerik:RadDateTimePicker SelectableDateStart="{Binding SelectableStartDate}" SelectedValue="{Binding StartDate, Mode=TwoWay}"/>

</DataTemplate>

</telerik:GridViewDataColumn.CellEditTemplate>
