MinutesOfHour

Can someone tell me what this property represents? I am using this through code but it would be nice to get the control representing this, also.

Can I add an array of values like [1, 15, 45] to represent I want this scheduled on the 1st, 15th and 45th minute of every hour?

A working example would rock my world.
Thanks,
Joel.

Columns bound to enum values produce occasional binding errors

I have a RadGridView containing 20+ columns, a couple of which are bound to Enum properties. Both row and column virtualization is turned on. When I scroll horizontally to bring the enum columns into view, I often get binding errors on the enum columns such as:

System.Windows.Data Error: 6 : 'StringFormat' converter failed to convert value 'Cleared' (type 'BookingStatus'); fallback value will be used, if available. BindingExpression:Path=Value; DataItem='GridViewCell' (Name=''); target element is 'TextBlock' (Name=''); target property is 'Text' (type 'String') FormatException:'System.FormatException: Format String can be only "G", "g", "X", "x", "F", "f", "D" or "d".

at System.Enum.ToString(String format)

at System.Enum.ToString(String format, IFormatProvider provider)

at System.Text.StringBuilder.AppendFormat(IFormatProvider provider, String format, Object[] args)

at System.String.Format(IFormatProvider provider, String format, Object[] args)

at System.Windows.Data.BindingExpression.ConvertHelper(IValueConverter converter, Object value, Type targetType, Object parameter, CultureInfo culture)'

My cell template for the Enum columns is very simple, with no explicit StringFormat:

<DataTemplate x:Key="Cell.Enum" DataType="telerik:GridViewCell">

<TextBlock Text="{Binding Value, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:GridViewCell}}}" />

</DataTemplate

The values for the columns actually do end up displaying correctly, with the enum values such as 'Cleared' all ok.

I suspect something is wrong with the virtualization - perhaps a column for another type is being reused for my Enum column as I scroll across, and that column's template is being applied to my enum column before all the column's settings are updated to the new column type?

Thanks in advance for your help, this is a fairly big issue for us as it's affecting scroll performance considerably.

I'm using version 2012.3.1017.40.

Scrollbar on a RadContextMenu

I am new to Silverlight. I have a xaml which contains a picker button. On click, its calls a 'Show' function. The Showfunction is handled in the xaml.cs file. IThe showfunction displays a RadContextMenu. A listbox is added to the RadContextMenu. The RadContextMenu/Listbox does not contain a vertical scrollbar. How do I add a scrollbar? And what do I add it to, Listbox or RadContextMenu?

Getting PDF Pages as Images

We are evaluating your tools to see if they will fit our needs. One of our requirements is that we need to be able to get an image of each page of a PDF so that we can further process it in our application. I noticed on another thread that there is a ThumbnailFactory that can be used to create an ImageSource from a RadFixedPage. I tried to use the PdfDocumentSource like so:

ThumbnailFactory tf = new ThumbnailFactory();

PdfDocumentSource docSource = new PdfDocumentSource(new MemoryStream(myPdfByteArray), FormatProviderSettings.ReadAllAtOnce);

foreach (RadFixedPage pdfPage in docSource.Document.Pages)

{

ImageSource pageImg = tf.CreateThumbnail(pdfPage, new System.Windows.Size(myWidth, myHeight));

// Do additional work here

}

...but docSource.Document is always null.

How can I get an image of each page in the PDF file?

Thanks,
Clayton

RadGridView Column Auto Sizing

Hi,

I am trying to do a gridview that has only one column that should size to the remaining area of the container it sits in. I set it to '*' but it will not take up the remaining size of the containing grid. The column that needs to size to the rest of the grid is the 'Patient' column. All others colums are required to be a fixed size.

The xaml is as follows:

FileName Property

This seems like it would be a common issue but I have not been able to find a reference in either the documentation or forums. I have a class that I want to edit using the RadPropertyGrid and one of the public properties is a string that contains a file path. I want to use the OpenFileDialog (or equivalent) to edit this property. Any help would be appreciated...

Thanks

Current Status of Printing?

Hi,

I've done some searches and found conflicting reports of the current status of printing the RadGridView control. Can someone say where we are today with this important, yet elusive, task?

I need a data grid control that can be printed effectively, including pagination, orientation, paper size etc. Is Telerik's RadGridView that control?

Thanks.

Aaron
