Hello!

I am trying to display a PDF file in the RadPdfViewer that is shown as having a white background in other PDF Viewer programs (SumatraPDF, Adobe Acrobat Reader, ...), but in the RadPdfViewer it shows a red background. Is this a bug or is my file broken somehow? Or am I missing a setting that changes this behavior?

Cheers

Hi

I want to implement the item zoom in and out in the listbox.Similar to the zoom of the Diagram.

I have a custom class that I'm adding to a VisualizationLayer. I'm using the following template to display it:

Works great. But I don't know how to get the ZIndex working. I tried adding my own ZIndex (that calls PropertyChanged), inheriting from ExtendedDataProvider, putting Canvas.ZIndex in the template but the z-order of the item never changes. If I use a normal PolygonData with the default template, the z-order updates.

In the recent project, I want to control the scrollViewer on the diagram and set the offset of the scrollViewer. I looked at the API and found that the offset property is not public. What should I do?

Any help would be appreciated.

Hi,

I noticed that some commands get executed/ changes saved when selecting a different tool.

For instance:

1. Seleting the tool to insert text
2. Selecting forms

The text is placed inside the image. This is pretty annoying if the user accidently clicked on it. Is there a way to persist this changes only when a user has clicked a custom button?

Best regards

Hello,

We have a RadGridView that has 150,000 rows (and so is using the default UI virtualization) as well as default column filters available on each column. When we check one of the "distinct values" checkboxes on the Name column, the resulting grid displays only entries for the selected name as expected -- however, it doesn't display all the results that were in the 150,000 rows. It's hard to tell how it is deciding where to cut off the results, but since each row has a time stamp we can see that it takes the top rows up until a certain point and then stops. So for one case, 69 rows were displayed when there were 624 rows in total for that selected name.

I've searched around quite a bit but couldn't find this exact scenario addressed -- do you have ideas/suggestions for this problem?

Thanks,

Chris

Hi,

I used a scheduleview with custom appointment and style.

I modified appointments in my viewmodel programmatically when I received message from Azure service bus. The problem is that the UI isn't updated. I have to scroll down and up to see changes in UI.

I tried this solution : https://www.telerik.com/forums/changing-appointment-start-end-not-reflected-on-ui but it didn't work.

Thanks for your advice

Here's my code :

public class TimeSlot : Appointment
{

....

        public void UpdateTimeSlot(TimeSlot source)
        {
            CopyFrom(source);

            _truckId = source.TruckId;
            TimeMarker = TimeSlotMarkerCollection.GetTimeSlotMarker(source.CurrentStatus);

            OnPropertyChanged();
        }

}

In my viewmodel :

public class DispatchBoardViewModel : ObservableObject
 {

        private void _listenerMessageService_MessageReceived(object sender, EventArgs e)
        {
            var dispatchList= ((MessageEventArgs)e)?.Message;
            dispatchList?.TimeSlots.ForEach(d =>
            {
                var displayedTimeSlot = TimeSlots.FirstOrDefault(ts =>[where_clause])
            );
            displayedTimeSlot?.UpdateTimeSlot(timeSlot);
            });

}
