Hi. I have window with button and RadTabControl with 3 TabItem.
Button has click event 
private void BtnPrint_OnClick(object sender, RoutedEventArgs e)
        {
            Random r = new Random();
            var Background = Color.FromArgb((byte)r.Next(255), (byte)r.Next(255), (byte)r.Next(255), (byte)r.Next(255));
            Brush brush = new SolidColorBrush(Background);
            modulCalculationDefect.pipeControl.Background = brush;

            RenderTargetBitmap targetBitmap = new RenderTargetBitmap((int)modulCalculationDefect.pipeControl.ActualWidth,
                    (int)modulCalculationDefect.pipeControl.ActualHeight, 96d, 96d, PixelFormats.Default);
            targetBitmap.Render(modulCalculationDefect.pipeControl);

            BmpBitmapEncoder encoder = new BmpBitmapEncoder();
            encoder.Frames.Add(BitmapFrame.Create(targetBitmap));

            MemoryStream stream = new MemoryStream();
            encoder.Save(stream);
            BitmapImage bmp = new BitmapImage();
            bmp.BeginInit();
            bmp.StreamSource = new MemoryStream(stream.ToArray());
            bmp.EndInit();

            imageControl.Source = bmp;
        }
So when i click button I must change backgroud modulCalculationDefect.pipeControl, make image and view this image in imageControl. This work when select RadTabItem where located modulCalculationDefect.pipeControl. When selected another item image in imageControl doesn't change.
How can I fix that?

Hello Telerik,

I want to use the RadAutoCompleteBox but it should be possible to input a value which is not part of the itemssource.
The user should be able to either select a value from the itemssource or add a new item.

In other words the autocomplete should be optional. Is this possible?

Thanks for help.

Greetings
Michael

Hello,

I found out that there's no such property inside the GridViewComboBoxColumn control to get the selected value. I tried a lot of things to get this value in my code but nothing worked, and I really need to use the selected value in my ComboBox since other cells will be supposed to be updated thanks to the selection.

Is there any way to do it please ?

I've two subsidiary questions : why this control doesn't contain this property like the RadComboBox, what's the point ? And, I also tried to write

And it appears that OldValueReference is unknown. I copied that from my var content, like in the pictures.

Thanks for your help !

Hi,

Will an export to MS Project be implemented in the future?
The CTP only mentions an import, not an export.

Best regards

Can I make combobox PART_SimpleFilterMemberComboBox editable with text searching?

I'm using Radgridview in silverlight and I need to highlight the highest value within every columns.
The data is generic and I don't know what the type will be, the number of columns or the header's name.

Thanks,

       we are using a telerik autocomplete box.  Now, the code pasted below works on ALL computers except my surface pro 2.  any reason you know of?

Interestingly, this used to work on my machine because I approved the developers update.

The problem is that even though the "SelectedServices" is being populated, the control on the UI is not getting it.  and the control on the UI is not sending down the data either.

I can post any more info you guys need to help trace this.  But again, code works on all computers except surface pro 2 with windows 8.1

Hi!

I can't move/drag any shape created to RadDiagram inside Visual Studio's designer. Shape is always created to the top left corner of the diagram.
Also even though I think I have all the necessary assemblies referenced I get an exception after trying to add RadDiagram (Wizard shows up and I use default selections and press "Ok" button).

Version of the assemblies are: 2013.3.1313.45

Assemblies I'm referencing are:
- Telerik.Windows.Controls.Diagrams
- Telerik.Windows.Controls.Diagrams.Extensions
- Telerik.Windows.Controls.Input
- Telerik.Windows.Controls.Navigation

- Telerik.Windows.Controls.GridView (I also have some gridview's in use)
- Telerik.Windows.Data

Exception after wizard closes:

I have had this problem for some time now, I'm currently using 2013 Q3 NET 4.5 components for WPF and it was the same with previous versions also.

What could be causing this problem?

Hello.  I am trying to solve the problem of keeping our data fresh using the Telerik WPF RadGridView.  I know that Telerik loads an in-memory copy of the collection that it binds to, but is there a way to keep it fresh?  We have a grid that queries 45,000 records.  Currently we have it working with a plain old windows grid by laoding in a page size at a time of records.  Because it goes back to the database each time we click the page buttons or do a sort or filter, the data stays fresh.  On the other hand, I also have a Telerik grid that queries the same set of records, but since it does not go back to the database for page operations and sorting and filtering, it gets stale data.  I verified this by updating some of the database fields and observing the old values instead of new ones.  Our work environment demands that the data be as fresh as possible (not just for insertion and deletion of records but for updating of existing records).  We have kicked around several ideas such as a refresh button, having a timer that goes back to the database to load every 15 minutes, or doing a database pull each time that the user does a paging, sort, or filter operation.  However, I am having a hard time finding the event in the RadGridPager that will let me make this call in the view model.  Is it even exposed?  Keep in mind that we are using MVVM, so I can use code behind if needed, but I would like to avoid that if possible.  Thank you.

Hi,

I'm trying to use the RadPropertyEditor for the first time. I have a simple business object with 5 Color properties. The RadPropertyEditor shows a standard TextBox (not a RadColorPicker) and if I try to update the color hexa the new value is not pushed back to my business object. I then try to use an EditorTemplate by intercepting the AutoGeneratingPropertyDefinitions event and set the Editor property. However I'm not able to figure out how my DataTemplate should like. The Rad WPF example use this:

...
<DataTemplate x:key=foregoundTemplate>
   <telerik:RadColorPicker SelectedColor={Binding Path=Foreground ...
...

This is not very extensible since the editor template needs to know the path of the property it's bind to. I don't want to make an editor for each of my 5 properties.

Do I missing something?

Thanks
