Hi,

I'm able to save my diagram but the loading is not working. After loading, the connectors show but the containers and shapes were missing. It seems that there is some issue in the deserialization of my nodes as the items in the raddiagram were only the connectors. I followed this example below but my raddiagram doesnt seem to deserialize my nodes when loading.

    public override NodeViewModelBase DeserializeNode(IShape shape, Telerik.Windows.Diagrams.Core.SerializationInfo info) 
    { 
        var node = base.DeserializeNode(shape, info); 
        if (info["MyPosition"] != null) 
        { 
             var position = Utils.ToPoint(info["MyPosition"].ToString()); 
         node.Position = position.Value; 
        } 
        return node; 
    } 

I am trying to use the AppointmentCalendarImporter to import iCal files exported out of Outlook (using Office Pro Plus 2016). This works quite well except the CATEGORIES from the .ics file are not importing.

It appears that the problem is that Outlook is exporting just the category name like this:

However, the importer is looking for something like this (got this example from using the Exporter):

Is there a way to get the Outlook format to load?

Thanks!

Hi

I am using a GridView containing 2 or 3 lines of data.I have to hide and show some lines related to the condition

But when I hide the row, there is an empty space (possibly a row with no data)

This way I hide the line (I tried both Collapse and Hidden)

How can I completely hide the Grid row?

Hello,

I would like to export my RadGridView to Pdf using the PrintPreviewControl and RadSpreadsheet. To create the workbook I use the ExportToWorkbook method like so:

and I style the cells like this:

This works fine until I have columns with very long text (with whitespaces) that won't fit on one line (neither portrait nor landscape orientation). I tried to use text wrapping on the cell style by setting the IsWrapped property to true, but this does not yield the desired result. Also "AutoFitColumnsWidth = true" does not seem to effect my columns either.

I also witnessed a strange behaviour concerning columns that are at the end of my GridView where I have to scroll to see them on screen.

When I show the PreviewControl before I scrolled to those columns, I get a different output than when I previously scrolled to those columns.

For better understanding, I attach three pictures of the results I get.

Any help would be appreciated.

Best regards

When I click on the EBS attribute, the window becomes unresponsive and it looks like it is shown in the gif picture.

Is there too much data?

How to optimize the pivot grid?

Secondly, I want to know how to customize the date string format

Hi,

I've got an application that is randomly crashing and it seems to be something with the xaml.

See below for the stack trace from the application - it doesn't seem to always happen. It's using implicit themes, I can't remember which one but its a mobile version. Is their a problem with my app or is it the xaml?

Hello!

Tell me how to redraw the graph without blinking.

Now after SetValue() "No series added" is displayed first, then a new series.

Thanks.
