Editing cell takes lot of time with Groups column for more than 500 recods.

Hi,

I have installed lastest RadGridView for WPF (Trial Version). I have assigned an ObservableCollection with 100000 records to it. It loads fine and also editing cells is fine. But it takes lot of time to edit when grouped by a particular column and whole system hangs for some time.

Themes don't apply to TabControl

Hi guys,

I'm currently evaluating RadControls and I can't get themes to work with RadTabControls and their RadTabItems.
I apply one of the built in themes to the application, eg

Telerik.Windows.Controls.StyleManager.ApplicationTheme = new Telerik.Windows.Controls.SummerTheme();

...and it works with the other controls but not tabcontrols/tabitems. Is there anything else I have to install/do?

Column moves when combobox open

Hello

I have a right to left grid
The last column in my grid is a ComboBoxColumn (in the attached file named "A")
when I open the combo , the column 'moves' under the header of the previous column (named "B")
that happens only when there is a horizontal scroll.

Thanks.

Slow Paste

I have a RadGridView that is bound to items that are slow to create. When many items are pasted into the grid, the UI freezes until all objects are created.

The slowness of the creation comes from database lookups and calculations.

Is there any way I can handle the creation of the objects by hand? I would like to use a separate thread.

Thanks!

Telerik copyright message

Hi,

By reading the licence agreement of telerik's product, I saw this:

You must include a valid copyright message in your Integrated Products in a location viewable by Authorized End-Users (e.g. “About” box) that will serve to protect Telerik’s copyright and other intellectual property rights in the Software

I've no problem with that. Can you give me the sentence you want to be displayed? Because I'm not sure to know exactly what is a "valid" copyright message.

Thank you.

Chart randomly skipping data.

Hi guys,

I'm evaluating RadControls and the chart is giving me grief.
The data is pretty simple (attached).
Here is my XAML:

<rad:RadChart Margin="20,20,0,0" Height="250" HorizontalAlignment="Stretch" x:Name="StatusChart" Grid.Column="2" >

Here is my code:

SeriesMapping seriesMapping1 = new SeriesMapping();

seriesMapping1.GroupingSettings.ShouldCreateSeriesForLastGroup = true;

seriesMapping1.GroupingSettings.GroupDescriptors.Add(new ChartGroupDescriptor("JobStatusDesc"));

seriesMapping1.ItemMappings.Add(new ItemMapping("MonthTotal", DataPointMember.YValue));

seriesMapping1.ItemMappings.Add(new ItemMapping("StatusMonth", DataPointMember.XCategory));

MonthlyTotalsChart.SeriesMappings.Add(seriesMapping1);

MonthlyTotalsChart.ItemsSource = MonthlyData;

Fairly straightforward, but the chart (attached) skips a lot of the data! The data it does show is correct, but 201006 should also show a Raised value of 1, 201007 should show Raised, Cancelled and On Site values. One of the months (201008) isn't there at all, and 201009 is likewise missing values. No value above 5 is shown at all, but the chart seems to allocate space for the extra bars in the graph.

What gives?

GridView will not display an image

I've spent hours on this and have tried many ways. For the life of me I cannot make a GridView display any image.

I have a class called Employee. I then have a List<Employee> which is bound to the GridView ItemsSource. All bindings are working just fine. The first column in the grid is a GridViewImageColumn. I have never had it display an image. I've set my Employee.Photo property to be a Bitmap, and Image, a BitmapImage, and I've used System.Windows.Drawing as well as System.Windows.Controls, and System.Media.Imaging (I think that was the 3rd one).

When loading the image for the employee, here's the latest code I've tried:

BitmapImage bmp = new BitmapImage();
bmp.BeginInit();
bmp.UriSource = new Uri(@"FULL PATH TO THE FILE", UriKind.Absolute);
bmp.EndInit();
Employee.Picture.Source = bmp;
SomeImageOnTheForm.Source = bmp; // To test the successful load.

What can possibly be wrong? The Image on the form loads the picture just fine. The grid never does.
