Nested properties are not loaded when the ComponenetType does not match the DeclarationType. The same setup is correctly presented when using the UI for WinForms' PropertyGrid.

Category: Calendar
Type: Bug Report


This is an issue in RadCalendar when we use Multiple month view. This problem can be reproduced in the WPF demo examples.

RadCalendar -> Selection range and Constraints

1. Set the radcalendar columns = 3.



2. Select a date in the month of May. For example select May 8th.


3. Click on the next button in navigation to move to next set of months. It should ideally have shown June, July and August after March, April and May. But it skips 2 months and goes directly to August, September and October.



4. If int he same way you select a date in April and navigate to next three months. It skips one month(June) and shows July, August and September


This happens if we have set the columns value to greater than 1. I guess in trying to set the 3 months to show in the calendar the selected date/month depending on if its the 2nd or the 3rd month in the sequence shown causes the calendar to skip 1 or 2 months respectively.

This can be replicated on one your demo projects. Let me know if you need a project from me.

I couldnt find a bug report or a question in the telerik forum on this topic. If its not reported before this should be a simple fix for you guys.

HTML parser does not handle the described scenario properly. Nevertheless this is not a valid css snippet, app should not be brought to inoperable state.

This is reproducible for images with FlateDecode and predictor value in the range between 10 and 15. As an example you may take a look at the DecodeParms property in the following image PDF dictionary:

<< /BitsPerComponent 8 /ColorSpace /DeviceRGB /DecodeParms << /BitsPerComponent 8 /Colors 3 /Columns 1024 /Predictor 15 >> /Filter /FlateDecode /Height 2868 /Subtype /Image /Type /XObject /Width 1024 /Length 1236707 >>

When importing document containing a destination which points to invalid page reference, KeyNotFoundException is thrown.

When all columns are readonly, the NewRowPosition is Bottom, a new row is added through the UI and the Tab key is pressed, an InvalidOperationException is thrown.

As a workaround, you can call the CommitEdit method inside a Dispatcher with a low priority in the AddingNewDataItem event:
private void Grid_AddingNewDataItem(object sender, Telerik.Windows.Controls.GridView.GridViewAddingNewEventArgs e)
            Dispatcher.BeginInvoke(new Action(() =>
            }), DispatcherPriority.ApplicationIdle);

When an appointment is double clicked, the edit appointment dialog is shown. When the escape button is clicked, the edit appointment dialog is closed. When the above 2 actions are performed in quick succession, the appointment disappears.

If you have a data validation, and there is an invalid field with the red border around it, if you hide this field via the filtering feature or the collapsing its group, the validation red border (and the tooltip) disappears.

To resolve this, you will need to update the ErrorTemplate of the input field (the TextBox). You can do this in the FieldLoaded event handler.

private void RadPropertyGrid_FieldLoaded(object sender, Telerik.Windows.Controls.Data.PropertyGrid.FieldEventArgs e)
    if (e.Field.Content is TextBox)
        var editor = (TextBox)e.Field.Content;
        var bindingExpression = BindingOperations.GetBindingExpression(editor, TextBox.TextProperty);
        if (bindingExpression.ValidationError != null)
            var errorTemplate = Validation.GetErrorTemplate(editor);
            Validation.SetErrorTemplate(editor, null);
            Validation.SetErrorTemplate(editor, errorTemplate);

Font weight, size and other current editing style properties are not preserved when document layout is performed, for example in the following cases:
- the document is in web layout mode and the controls is resized
- scroll bar changes its visibility.

Steps to reproduce:
- Set RadRichTextBox to Web layout mode.
- Type a word, select it and make it bold.
- Press enter and type a word
- Repeat the previous step until RadRichTextBox height is reached and scrollbar appear.
- Type a word.
Expected: The last word is bold.
Actual: The last word is not bold.

The GridViewMultiColumnComboBoxColumn of RadGridView allows you to enter the edit mode of the corresponding cells even when the IsReadOnly property of the column is set to True. 

This is also reproducible when RadGridView.IsReadOnly property is set to True

This is reproducible only when the SelectionMode is set to Multiple.

This behavior differs from the standard MS FileDialogs, where the expand arrow is not visible for such folders.
