 When defining a Date column like

<tdg:DataGridDateColumn PropertyName="ExpiryDate" HeaderText="Expiry"/>


and binding data with a type with Nullable datetime

public System.DateTime? ExpiryDate
{
   get { return _expiryDate; }
   set { SetProperty(ref _expiryDate, value); }
} 

We get an exception

 

Is there a workaround?

 

Thanks

Hello ,

An Admin say me to explain a way to use a QrCode export in PDF .

So what we need ?

I use your RadBarcode to create a barcode so simple . But now this QrCode i want to get him as an imageStream and then use it on a PDFCreator .

For the moment i try to create a view with QrCode -> export this view as an Image -> change that image on ImageStream -> Use this ImageStream on PDfCreator .

I hope you understand me !

Sincerly,

 

Anthony Ranuuzzi

As the subject:

Before upgrading to the latest version of Telerik Controls, the Drag/Drop functionality worked correctly but after upgrading the list no longer updates and the item moved returns back to the original position.

Not using "ReorderEnded", everything works fine but this is needed to detect that something has been moved.

Hello!

When include a CheckBox inside a simple ListView (also with RadListView), and try implement the CheckBoxUserCommand Id="IsCheckedChanged" the control appears disabled.

I use MVVM and I need binding the checkedChanged Command to execute a custom operation related to specific row of the ListView; but, how can i know which element of the ListView affecting when checked  / unchecked the CheckBox. Here the code:

PD: Then prefix name of  <checkBoxComamnds:CheckBoxUserCommand>  is wrong, should be <checkBoxCommands: > (Error in word: Comamnds...)

XAML

<AbsoluteLayout BindingContext ="{Binding ViewModel}">      
        <ListView IsRefreshing="{Binding IsRefreshing, Mode=TwoWay}"
                ItemsSource="{Binding CalendarList}">

Currently RadListView  has only pullTorefresh which updates the list if user scrolling the list downwards.. But it is good to have pullUptorefresh kind of gesture. since mostly we need to populate the list when user scrolling up. a gesture direction setting (pullup or down) would do.

Hello,

If you take a look to the provided screenshot you'll see what's wrong at first sight.

If you add a numeric input belong other kind of input.

You will see that the numeric input is the only one control to have a style which look like the control is being focused.

 

Current behavior

the NumericInput color is using the accent color for all states. We can't guess whether the control is focused or not.

Expected behavior

the numeric input should have a default color and use the accent color only when focused. Use the default entry style for the entry of the numeric input.

Workaround

you can also expose a numericButtonStyle property or some bindable property to allow us to set the color.

 

Right now, the control is unusable because of its look. Too bad, the implementation behind is nice.

It was better to create my own control which does the same. I use Telerik to avoid that.

 

Have a good day and thanks for your attention.

Best regards

A great first effort! Many thanks!
After some use I do have these suggestions:

1. When User changes LayoutMode the ZoomLevel property changed event should also be fired. I have a Numeric Textbox to adjust viewer ZoomLevel and would like to see its text update on a LayoutMode change. However when LayoutModeChanged fires the ZoomLevel has not yet changed nor does ZoomLevelChanged later fire.
2. The toolbar item for Fit to Width should be a Toggle in all cases, i.e. toggling between Fit Width and Fit Height (or Fit Page) and should be effective at all times (sometimes has no effect if LayoutMode changed to Single Page).
3. The toolbar item to toggle LayoutMode should honor an assignment of its text property.
4. I'm currently using the change in VisiblePagesCount to determine the document is visible. However a "Loaded" event might be even better.
5. I would like to release the viewer's memory of the document before closing the XAML page. An Unload command would be helpful. For now I just assign Source = null.

Please add an option to center the Xamarin Popup on the page, both horizontally and vertically.   The popup should not move when pickers (and other similar controls) are opened/closed.

Thank you

Hello Telerik Team,

I would like to report a bug I found on Android (not iOS).

If you use a RadCalendar inside a content page which is inside a TabbedPage, you can't swipe on the RadCalendar when it is in ViewMode=Week.

You have to draw a diagonal to make it works otherwise, the swipe (on the RadCalendar) is handled by the TabbedPage and it changes the current page being displayed.

 

If the RadCalendar ViewMode is set in MultiDay, the Swipe is well handled by the RadCalendar (instead of the TabbedPage).

 

Expected behavior : swiping on the RadCalendar in ViewMode=Week should change the displayed week (like it does in ViewMode=MultiDay).

Current Behavior : swiping on the RadCalendar in ViewMode=Week should change the selected page of the TabbedPage.

 

Why I think it is a bug : in ViewMode=MultiDay, the swipe isn't handled the same way : it actually change the displayed day and doesn't change the current page of the TabbedPage control.

PS : if the RadCalendar ViewMode is set to Month, the swipe to change the displayed month is from top to bottom or bottom to top unlike the Week mode which handle swipe from right to left or left to right.

 

I wish you a happy new year and a lot of bug fix with a lot of new feature released :)

This would allow the user to set advanced Entry properties and layouts.

One such use case was requested:

Set the Entry's MaxLength and add an inline "215/300" to inform the user of how many characters are left for that message.

After first appearing on screen, the DataGrid will cause a NullReferenceException when navigating away. Also occurs if you have a DataGrid in a RadTabView and you switch to another tab.

Same code works on UWP, Android. Crashes on iOS.
