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>

<telerik:GridViewDataColumn.HeaderCellStyle>

<Style TargetType="telerik:GridViewHeaderCell">

<Setter Property="Background" Value="#437F7B"/>

<Setter Property="Foreground" Value="White"/>

</Style>

</telerik:GridViewDataColumn.HeaderCellStyle>

</telerik:GridViewDataColumn>

Duvidas sobre RadGridView e suas propriedades

Doubts about RadGridView and its properties

Hello, the company I work for Telerik and adiquiriu components are half out of things to be beginners immediately wanted to know how to translate the words of RadGridView their descriptions of their filters, a feature already found out that we were wanting is FilteringMode = "FilterRow "a field to filter above each column, but I can not do typing and automatically the grid has to be updated with their data, must always be terminated with a carriage return so the filter is triggered.
So summarizing. Translation to Portuguese and filter by typing estamso also wondering if you have a way of using wildcards in the filter.
Ex Word: PRODUCT DEVELOPMENT TEST PRA, using property FilteringMode = "FilterRow" in your field could do the following to filter a kind of LIKE sql, but only when automatically added a special character: eg PRODUCT * DEVELOPMENT TEST *. Concluded filtering would bring me everything iniasse with PRODUCT TEST and DEVELOPMENT and contain the * would be the starting point.!

NOTE: Apologies for the song is in Portuguese

Already agredeço
