Hello All,

   In the private bool Telerik.Windows.Controls.GridView.GridViewDataControl.Move(FocusNavigationDirection navigationDirection) method, there is an unchecked condition in the FocusNavigationDirection.Next and Previous switch condition that throws a NullRefereceException.  Below is the code snippet:


I know its a bug because just below that is the proper form of the condition that checks this.CurrentCell for null:

Default setting for the EditTriggers in the DataGrid is "Mouse DoubleClick". However I want to be able to edit the cells if either of the following events happen:

1. Enter Key Press
2. Mouse DoubleClick
3. F2 Key Press

Can you tell me how to do this? I didn't find anything in the documentation regarding this.

Hi There,

Hello!

I have problem with RadGridView grouping.

<telerikGrid:RadGridView x:Name="InmattVolymGridView" Language="sv-SE" AutoGenerateColumns="False"         
                                         ShowColumnFooters="True"
                                         VerticalAlignment="Top"
                                         ItemsSource="{Binding InmattaVolymer, ValidatesOnDataErrors=True, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
                                         Validation.ErrorTemplate="{DynamicResource validationTemplate}"
                                         ToolTip="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors).CurrentItem.ErrorContent}" >
                   
                    <telerikGrid:RadGridView.Columns>
                        <telerikGrid:GridViewDataColumn DataMemberBinding="{Binding Sortiment}" Header="Sortiment" Width="85"/>
                        <telerikGrid:GridViewDataColumn DataMemberBinding="{Binding InmattM3F}" Header="m3f Inmätt" Width="100" >
                            <telerikGrid:GridViewDataColumn.AggregateFunctions>
                                <telerikData:SumFunction SourceField="InmattM3F" />
                            </telerikGrid:GridViewDataColumn.AggregateFunctions>
                        </telerikGrid:GridViewDataColumn>
                        <telerikGrid:GridViewDataColumn DataMemberBinding="{Binding SortimentTyp}" Header="Sortimenttyp" Width="85"/>
                    </telerikGrid:RadGridView.Columns>
                    <telerikGrid:RadGridView.GroupDescriptors>
                        <telerikData:GroupDescriptor SortDirection="Ascending" Member="SortimentTyp">
                            <telerikData:GroupDescriptor.AggregateFunctions>
                                <telerikData:CountFunction Caption="Total volym:" />
                            </telerikData:GroupDescriptor.AggregateFunctions>
                        </telerikData:GroupDescriptor>
                    </telerikGrid:RadGridView.GroupDescriptors>
                 </telerikGrid:RadGridView>

I get 'Invalid Property or Field' on Member in GroupDescription. How should I connect the grouping to the column.

Best regards / Anna

Two questions into one....

1: Can I customize the style of the scrollbars when using the scrolling/zooming features
2: Can I make it so that the width of the bars are fixed?

I'm trying to make a chart where there are a larger number elements that can be scrolled through (keeping the Y-Axis fixed).

Thanks!

Hi,

I'm trying to bind the background of a GridViewDataColumn to a property in my ViewModel:

<radGrid:GridViewDataColumn Header="State" Width="090" Background="{Binding Path=State, Converter={StaticResource StateToColorConverter}}" DataMemberBinding="{Binding Path=State}"/>

Based on the value of the State property the background should change: if State = new, the background should be green, if State = rejected the value should be red, and so on.
However, if I bind the State property to the Background, i get a BindingExpression path error stating that my State property is not found on my object, while the same databinding works fine on the DataMemberBinding.
Anyone got a clue what is wrong here?

The Xaml:

and the code from the viewModel:

Thanks a lot!

Not a question this time. I just thought I might post this in case it is of help to others playing with the RadMap.
 
This is how to add images to the radmap map with a bit more control over the image than is available by simply adding a bitmap using the pinpoint method.

        // Set provider
                BingMapProvider provider = new BingMapProvider(MapMode.Aerial, true, "YOUR CODE GOES HERE");
                provider.IsTileCachingEnabled = true;
                mWindow.radmap.Provider = provider;

        // Create information layer
                iLayer = new InformationLayer();
                iLayer.MapControl = mWindow.radmap;
                mWindow.radmap.Items.Add(iLayer);

        // Create a new image object and add it to bing map.
                Uri uri = new Uri(@"" + imageName, UriKind.Relative);

                BitmapImage bitmap = new BitmapImage();
                bitmap.BeginInit();
                bitmap.UriSource = uri;
                bitmap.EndInit();

                Image image = new Image();
                image.Source = bitmap;
                image.Opacity = 0.85;
                image.Width = imageWidth;
                image.Height = imageHeight;
                image.Stretch = Stretch.UniformToFill;
                image.SnapsToDevicePixels = true;
                image.Name = Name;

        // When added to map, centre image over Lat/Long rather than use upper left corner for placement
                image.VerticalAlignment = VerticalAlignment.Center;
                image.HorizontalAlignment = HorizontalAlignment.Center;

        // Add the image to the map
                MapLayer.SetLocation(image, new Location(dLatitude, dLongitude));
                iLayer.Items.Add(image);

Hello!

I’m working with your Chart, and I found it working incorrectly.

<QuickStart:ExampleControl x:Class="Telerik.Windows.Examples.Chart.WPF.TwoDimensional.Bar.Example"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:QuickStart="clr-namespace:Telerik.Windows.QuickStart;assembly=Telerik.Windows.QuickStart"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">
    <Grid>     
        <telerik:RadChart x:Name="RadChart1"/>
    </Grid>
</QuickStart:ExampleControl>

As a result I expect to see a Chart of 0x0 size, but instead it’s 800x600.
I do not understand where this size comes from, because it’s not written anywhere.
How can I solve that problem?
The matter is crucial for me, since in my application I need to implement the floating layout.
Thank you very much.

Out of the blue, I have started getting an assembly error when i try to debug my application. I am utilizing RadControls for WPF Q1 2010 in VS 2008:

Error   1   Could not load type 'Microsoft.Windows.Design.Metadata.ProvideMetadataAttribute' from assembly 'Microsoft.Windows.Design.Extensibility, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. Line '1' Position '491'.   C:\Documents and Settings\akedzier\My Documents\Visual Studio 2008\Projects\CCMB_WPF\WpfApplication1\panels\Panel_04.xaml   12   13   CCBM_Wpf

Here is the code it tags as problematic. It is almost verbatim from the Telerik example:

This has compiled and run just fine previously. Not sure what changed to cause the error.

        I have seen the instruction about Map and know it supports Bing's map.  Now I wanna know if it supports Google's map.  If the answer is YES, how to do it?
