Greetings,
I have used rad datagrid and it is working fine. But I have basically 1 problems that I felt very hard to implement.
1. Using Custom Layout like in the blog
http://blogs.telerik.com/blogs/posts/09-02-03/how_to_use_custom_row_layouts_in_radgridview_for_wpf.aspx
but to start with I have strange error like
so I could not start to edit the example in the blog. Can we edit the Values of rows that is inside the Custom row layout and also save it to the database also? Can the Custom layout hold other edit templetes like Combobox or masked text box in columns like Sex where there are only two option like male or female or in Phone number. Saving the edit on database also should be on focus. Because
dataContext.SubmitChanges();
was working fine on other project but under exactly same condition it is not working now.
If you want to go through my project here is a link of it.

Hi,
I'm using the RadMap to display KML data exported from Google Earth. I've found that pushpins appear really large by default (about 64x64) and that it is the top left corner of the image that points to the location, and not the pin. This looks ok when zoomed in, but it doesn't appear to point to the right location at all after you zoom out a little.
I'm loading in the elements using KmlReader.Read(Stream) and adding them to an InformationLayer. Is this a known problem with either Google Earth or RadMap?
Thanks,
Kyle

I am trying to apply the telerik metro theme to the WPF controls. While most controls looks OK, the PasswordBox somehow received a strange double border (see attached image). This issue seem to only affect the Metro Theme, other themes such as the Windows7 Theme looks ok.

Hello,
In a RadPaneGroup with a RadGridView we are showing some detials of a SQL search. In the background is a ViewModel and one of the property contains the resultrecords as array. Each new search request will create a new array of records and through a binding it changes the ItemsSource property of RadGridView.
new Version 2012.2.725.40: the focus will jump into the RadGridView when RadPaneGroup is floating
old Version 2012.1.215.40: its all ok, the Fosuce stay in e.g. TextBox
a SampleApp below

All of a sudden I can't run any app with telerik WPF. I upgraded to Q2 2012 and it crashed visual studio without completing. Now I can't run existing projects or start new ones using WPF. I tried uninstalling and reinstalling but no difference.

Hi,
in scheduleview I am do following:
- every time the visible range is changed I set the AppointmentsSource = null. After that I add some new Appointments (which fit into the visible range). After that I call UpdateLayout().
scheduleView.BeginInit();
scheduleView.AppointmentsSource = null;
scheduleView.AppointmentsSource = observableAppointments;
scheduleView.EndInit();
scheduleView.UpdateLayout();
This is ok, when I click the back and forward buttons on schedule view. But when I change from Week View into Day View, I get an exception. I debugged schedule view and got the exception in AppointmentsPanel.cs in
private void UpdateMaxDesiredSize(GroupHeader header, bool isHorizontal)
{
header.Measure(infinity);
int level = header.Level;
Size desiredSize = header.DesiredSize;
int adjustLevel = level - 1;
double levelMaxDesiredLength = this.GetMaxDesiredLength(adjustLevel);
double length;
if (isHorizontal)
{
length = header.DesiredSize.Width - header.BorderThickness.Right;
}
else
{
length = header.DesiredSize.Height - header.BorderThickness.Bottom;
}
levelMaxDesiredLength = Math.Max(levelMaxDesiredLength, length);
this.headerMaxLengthLevels[adjustLevel] = levelMaxDesiredLength; Here headerMaxLengthLevels has zero entries.
}
What's the reason for this?
Regards,
Ronald
