Grid scroll behavior when grouping applied

We have approx 1000 rows in a RadGridView (version 2011.2.808.40) with grouping on one column resulting in 5 groups.

I have noticed that when scrolling down using the arrow key that when you scroll past a group header (GridViewGroupRow) the grid will auto scroll the group header to the top of the view port before continuing to scroll as normal. This produces a jump in the display, especially as the group header is initially out of sight (just beyond the bottom of the view port).

Is there any way to turn this behavior off, so that a group header scrolls into view and then up the page like any other row?

Thanks!

Unlocking files

I have saved files from a data base then used the paths to bind them to my images in my book. But now I need to release those images and rebind with different images. I am not able to delete out the image files that I created to display from the first book that was created. How do I clear the locks on the files so I can recreate them from other images in the database?

private void Process_Tiff(BookView wpfbook, string TempFile)

{

RemoveOldFiles();

//Sets each page to an image

Image img = Image.FromFile(TempFile);

int count = img.GetFrameCount(FrameDimension.Page);

List<BookItem> MyBook = new List<BookItem>();

for (int idx = 0; idx < count; idx++)

{

img.SelectActiveFrame(FrameDimension.Page, idx);

int currentpage = idx + 1;

string TempPageFile = DefaultPath + DocOcc.ToString() + currentpage.ToString() + ".TIFF";

// and then create a new Image from it

img.Save(TempPageFile);

dFile df = new dFile();

df.File_Path = TempPageFile;

FileList.Add(df);

MyBook.Add(new BookItem()

{

Title = TempPageFile

});

}

img.Dispose();

wpfbook.RadBook1.ItemsSource = MyBook;

}

This is the code where I create a file for each page of my Tiff file. Then I use this code to try and remove it. But I am not able to remove the file.

private void RemoveOldFiles()

{

((BookView)((ElementHost)panel1.Controls[0]).Child).RadBook1.ItemsSource = null;

int count = 0;

IList<dFile> holddf = new List<dFile>();

foreach (dFile dfrow in FileList)

{

try

{

File.Delete(dfrow.File_Path);

count++;

}

catch

{

dFile df = new dFile();

df.File_Path = dfrow.File_Path;

holddf.Add(df);

count++;

}

FileList = holddf;

}

The result is always faling in to the Catch and the error is always that the file is in use. Hopefully this helps someone help me.

Explicit UpdateSource() with RadDatePicker

I have a wpf window with a search button and some fields to enter the search criteria. Some of the search fields are RadDatePicker controls which are bound to a custom object. Wpf does not update the custom object with changes until the field loses focus. When the search button is clicked, my code checks if each field has the focus. If it does, it calls UpdateSource() on the BindingExpression to make sure the custom object has the current values.

This is not working with RadDatePicker. I call UpdateSource() and it does not update the value in my custom object. I am binding to the SelectedDate property. Everything works fine when I tab out of the RadDatePicker control before clicking the search button.

Is there a way tell RadDatePicker to update the source without moving the focus?

The IsFocused property on RadDatePicker never seems to be true so that might be a bug.

Exception thrown when DataBound item changed

I have a RadPropertyWindow where the selected item is determined by DataBinding:

<telerik:RadPropertyGrid x:Name="_radPropertyGrid" Grid.Row="2" Item="{Binding SelectedElement}" />

When the SelectedElement is changed from NULL to an element, it works as expected.

Then, when this element changes again, an exception gets thrown.

How to find a floating RadPane?

This works well for docked RadPanes:

RadPane realPane = null;

IEnumerable<RadPane> childPanes = MainDockingManager01.ChildrenOfType<RadPane>();

foreach (var r in childPanes)

if ((r as RadPane).Title.Equals(theName))

{

realPane = r;

break;

}

return realPane;

However the enumeration does not contain the target RadPane when the
Pane has been un-docked and is floating. As a matter of fact, if there is only
one RadPane present, the enumeration of MainDockingManager01.ChildrenOfType<RadPane>
returns an empty set.

How do I find a floating child? Do I search something other than MainDockingManager01?

Thanks in advance!

Issue with RadGridView and DynamicObject

Hi,

I'm using WPF controls 2011.3.1220.40, and using a MVVM pattern with a ViewModel that uses DynamicObject to expose Model properties to the View.

Displaying dynamic property data in the gridview works fine, grouping on one of the real ViewModel properties works fine. But when the user tries to group by one of the dynamic property columns, a null reference exception is thrown (stack trace below). After the user clicks the grouping icon, TryGetMember is never called.

I've created a small project to demonstrate the issue, but could not upload a zip file. So below I've pasted a .xaml and it's codebehind. To see the problem, try grouping on the "One" column (works), and the "Two" column (exception).

I'm really hoping Telerik folks can look into this issue asap.

Thanks

Grid view theme checkbox

We have a Gridview used with column one as the checkbox for selection. ON mouse hover of the checkbox the theme color looks blue which is as desired. But when the checkbox is selected, it turns grey or it does not attain the theme feature. How do we make it theme specific color on selection?

AppointmentCalendarExporter bug for Every X Days

Hi,

I use the AppointmentCalendarExporter behind a WCF service to produce an ICal stream. This is then imported as a subscription to Outlook.

When an appointment has a recurrence pattern that is every 2 days (See the attached example). it produces the following output (just for that appointment)

BEGIN:VEVENT

DTSTART;TZID=E. Australia Standard Time:20111225T050000

DTEND;TZID=E. Australia Standard Time:20111225T120000

SUMMARY:Test recurrence

UID:a49ee7e8-7813-4348-b7d7-0fdba1934521

IMPORTANCE:None

RRULE:FREQ=DAILY;UNTIL=20120103T020000Z;INTERVAL=2;BYDAY=SU,MO,TU,WE,TH,FR,

 SA

END:VEVENT

However, this can't be imported into Outlook. There is a conflict in the recurrence rule, between FREQ and BYDAY. If I remove the BYDAY, then it gets imported ok.

I think this is a bug.
