Adding/Editing timestamp column in the grid

I have a scenario where one column in the table is a timestamp (date + time). I have my grid column configured as follows:

<telerik:GridViewDataColumn

UniqueName="Timestamp"

DataMemberBinding="{Binding Timestamp}"

Header="Timestamp"

DataFormatString="{} {0:MM/dd/yyyy HH:mm:ss}"

IsFilterable="False" />

The property is coded as:

public DateTime? Timestamp

{

get

{

... returns either NULL or datetime object

}

set

{

_timestamp = value;

}

The display part is working fine: an example of the value displayed is: 12/20/2020 18:40:00

The problem I have is when adding a new row or editing an existing row. When adding a new row, the grid displays an empty row, and if I type in "12/20/2020 18:40:00" and tab out of the column to go to the next column, the timestamp column value is set to NULL (when putting a breakpoint on setter) and the timestamp I entered is wiped out. If I just type the date part (12/20/2020) and tab out, things work fine: the value is set correctly and the column displays "12/20/2020 00:00:00". I observe similar behavior when trying to edit a row. Do I need to specify a mask, a converter, or something else to get the column to properly accept the timestamp?

Thanks

Andrey

constrain ResizeBehavior to days

I have a gantt chart wherein the time is measured in days, at the finest level. So time is not necessary for me.

I am using RadDateTimePicker controls for start/end, and I can control their behavior (limit to days input) by setting the attribute:

InputMode="DatePicker"

So, basically, if CustomResizeBehavior|CustomDragDropBehavior is turned on, I would like the resizing or dragging of a gantt task to lock to days, and not fall to times in between days. Is there any way to accomplish this behavior?

Tab Key Issue when input Mode = TimePicker

I'm seeing the following behavior with the DateTimePicker when InputMode=TimePicker.

With cursor in textbox, hit down arrow to open time picker popup.
Then hit tab key to move focus to list of selectable times
Keep hitting tab until focus is on the time you would like to select
Hit enter. Popup closes but time was NOT selected. Appears that only a mouse click will select a time. Is there a setting that will enable selecting a time with the keyboard?

Also,

With cursor in textbox, hit down arrow to open time picker popup.
Then hit tab key to move focus to list of selectable times
Keep hitting tab until focus is on the time you would like to select
Hit enter and popup closes.
Hit down arrow to open time picker.
Hit tab key to move focus to a selectable time. Focus does not move to list of times. How can I get the focus back into the popup to select a time with the keyboard?

Thanks in advance!

Drag Copy of Appointment to ListView

Hi

I would like to drag-and-drop an Appointment from ScheduleView to a ListView. The (visual) effect should be that it drags a copy of it, leaving the item in ScheduleView intact. I've followed the example for ScheduleView Drag-and-Drop, and everything works except the item being removed from ScheduleView. How do you recommend I go about this?

Christian

RadDateTimePicker two clicks before DropDown button displays

I am using RadDateTimePicker controls for Start/End columns in the RadGanttView:

<telerik:RadGanttView.Columns>
<telerik:TreeColumnDefinition Header="Title" />
<telerik:ColumnDefinition MemberBinding="{Binding MyFormattedStart}" Header="Start" ColumnWidth="100" >
<telerik:ColumnDefinition.CellEditTemplate>
<DataTemplate>
<telerik:RadDateTimePicker SelectedValue="{Binding Start, Mode=TwoWay}"
InputMode="DatePicker" />
</DataTemplate>
</telerik:ColumnDefinition.CellEditTemplate>

and the same for End...I have to click two times in the cell before the DropDown control displays so that I may use the control to change the value.

I would like to click only once. It is not intuitive to have to click again.

I did notice if I do this on the same row, e.g., changed the Start date with the DropDown, I can then go to the End column and just click one time to use the DropDown for that cell.

So, I guess the first click is required to select the row, and then once the row is selected, another click to display the DropDown.

Is there any way to configure the control/cell such that a single click in a Start or End cell selects the row *and* displays the DropDown?

Thanks, nelson

editvalue not firing when clicking away

I have the following issue:

I am binding a radgridview to a viewmodel and am currently not using the code behind and taking care of all the logic in the VM.

There is an "Apply" button bound to an IsDirty property being set once data changes in any of the bound items in the radgridview - this
is done via propertychanged events etc.

If I edit a value and click "apply" without clicking anywhere else, the edited value isn't commited to the bound model and apply doesn't
take the latest/most up to date value.

The closest thing I could find in forums is: http://www.telerik.com/community/forums/winforms/gridview/rowstate-question.aspx
but that didn't really help me.

Do you have any suggestions how I can get this to work, without breaking my design pattern.
