Hi,

I have played around with the layout properties with no success attempting to align the menu items to the right hand side of the menu however I am unable to do so, is this a limitation or am I doing something wrong?

Thank you,

Xavier.

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?

[Solved] 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.

MouseDoubleClick on Item

Hello,

I have problem using the event "MouseDoubleClick" on RadTreeViewItem.
It is handled for each branch item and it don't care about e.Handled = true.

Example :

    
                    <telerik:RadTreeView IsDragDropEnabled="True" MouseDoubleClick="treeView_MouseDoubleClick">  
        
                        <telerik:RadTreeView.ItemContainerStyle> 
        
                            <Style TargetType="{x:Type telerik:RadTreeViewItem}">  
        
                                <Setter Property="HorizontalContentAlignment" Value="Stretch"/>  
        
                                <Setter Property="IsExpanded" Value="True"/>  
        
                                <EventSetter Event="MouseDoubleClick" Handler="treeViewItem_MouseDoubleClick"/>  
        
                            </Style> 
        
                        </telerik:RadTreeView.ItemContainerStyle> 
        
                        <telerik:RadTreeView.ItemTemplate> 
        
                            <HierarchicalDataTemplate ItemsSource="{Binding Children}">  
        
                                <Border BorderThickness="1" BorderBrush="LightGray" Margin="2" CornerRadius="5">  
        
                                    <Grid> 
        
                                        <Grid.ColumnDefinitions> 
        
                                            <ColumnDefinition Width="Auto"/>  
        
                                            <ColumnDefinition Width="*"/>  
        
                                        </Grid.ColumnDefinitions> 
        
                                        <TextBlock Grid.Column="0" Text="{Binding Key}" Margin="3,0,10,0"/>  
        
                                        <GridSplitter Grid.Column="0" Width="1" Background="LightGray" ResizeDirection="Columns" dragDrop:RadDragAndDropManager.AllowDrag="True" dragDrop:RadDragAndDropManager.DragQuery="GridSplitter_DragQuery"/>  
        
                                        <TextBlock Grid.Column="1" Text="{Binding Text}" Margin="3,0,0,0"/>  
        
                                    </Grid> 
        
                                </Border> 
        
                            </HierarchicalDataTemplate> 
        
                        </telerik:RadTreeView.ItemTemplate> 
        
                        <telerik:RadTreeView.Items> 
        
                            <local:PairText Key="line1" Text="Some text for line1"/>  
        
                            <local:PairText Key="line2" Text="Some text for line2"/>  
        
                            <local:PairText Key="line3" Text="Some text for line3">  
        
                                <local:PairText.Children> 
        
                                    <local:PairText Key="line3.1" Text="Some text for line3.1"/>  
        
                                    <local:PairText Key="line3.2" Text="Some text for line3.2"/>  
        
                                    <local:PairText Key="line3.3" Text="Some text for line3.3"/>  
        
                                </local:PairText.Children> 
        
                            </local:PairText> 
        
                            <local:PairText Key="line4" Text="Some text for line4"/>  
        
                            <local:PairText Key="line5" Text="Some text for line5"/>  
        
                        </telerik:RadTreeView.Items> 
        
                    </telerik:RadTreeView>

    
                    private void treeView_MouseDoubleClick(object sender, MouseButtonEventArgs e)  
        
                    {  
        
                        MessageBox.Show("Tree");  
        
                        e.Handled = true;  
        
                    }  
        
                    private void treeViewItem_MouseDoubleClick(object sender, MouseButtonEventArgs e)  
        
                    {  
        
                        PairText pair = (sender as RadTreeViewItem).Item as PairText;  
        
                        MessageBox.Show("Item : " + pair.Key);  
        
                        e.Handled = true;  
        
                    }

When I double click on "line3.2" I want to obtain only the "Item : line3.2" message but there is "Item : line3" and "Tree" messages too.

Have you any suggestions ?

Thanks,
Guillaume R.

Modal Load Screen - Doesn't go away

Sometimes when refreshing my grid I'm getting a modal overlay (transparent navy blue in color) with a indeterminate load circle on it.

The data still updates under the modal.. but the modal does not go away.. this behavior is reproducible.. but seems to be specific to certain data I'm changing in my grid.

Any ideas?

[Solved] Clipboard is empty when application has been closed

Hi everybody,

if I copy data of the RadGridView into the clipboard I can paste it into an Excel sheet only as long as the source application (e.g. the demo application but also my own application) is running. Is there a way to keep the data in the clipboard after closing the application?

Regards Uli

Speed in a Grid.

I put this control on a grid and it dramatically reduces the rendering speed of the grid. It takes noticeably longer to scroll down.

Am I doing something wrong?

Here is what I have added to the Grid.

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=Rating}" Header="Rating" MinWidth="60" Width="SizeToCells">

<telerik:GridViewColumn.CellTemplate>

<DataTemplate>

<telerikInput:RadRating Name="_leadRating" Value="{Binding Path=Rating,Mode=TwoWay}" UseLayoutRounding="True">

<i:Interaction.Triggers>

<i:EventTrigger EventName="ValueChanged">

<cmd:EventToCommand Command=

"{Binding Path=DataContext.ChangeRatingCommand, RelativeSource={RelativeSource FindAncestor, AncestorType=UserControl, AncestorLevel=1}}"

CommandParameter="{Binding}" />

</i:EventTrigger>

</i:Interaction.Triggers>

</telerikInput:RadRating>

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

</telerik:GridViewDataColumn>
