public string FirstName { get; set; }  

public string LastName { get; set; }  

public string JobTitle { get; set; }  

public List<Address> EmpAddress { get; set; }  

}

 

public class Address

Hello


There is a demo application to test some components of telerik. No complex code, only "play" with some properties.

From visual studio works great, including the publication did not present any problems, no warning, no errors.

So far so good ...

However, when you want to run the published application from the IE browser, it displays an error window abruptly.

Running the application from within visual studio shows aparentmente an initialization error telerik controls, something like:



This application in the event Page_Loaded performs an initial load of data in a RadGridView against sqlserver is performed without any problems, showing the data and then to the second application is aborted with the error described above.

How I can solve this?


In advance thank you all ....

Am I aiming for the wrong thing to think I can use the RadTimePicker to select a Timepsan?

I need get rid of the AM PM and also stop it from thinking/displaying 00:00:00 as 12:00PM?

ohhh and what exactly am i binding to? SelectedTime={binding TimeSpan}?

thanks in advance

Hi,

I have created new GridViewDateTimeColumn that will handle DateTime properties. In this column I have added one dependency property that will define StringFormat for DateTime values.


xaml


However, since the cell/column layout is created only once, I am unable to force the Column to rebind its values. StringFormatChanged is executed, and StringFormat property for column DataMemberBinding is set correctly, but original StringFormat is still active.

How can I make this work?

Hello,

I have a TreeListView which is supposed to show a collection with different filters applied in two view states, the states are maintained by one bool property in the view model.

The value converter works correctly in that I can see the values being passed and returned, and in one of the states all items in the collection are shown correctly in the view. When switching back to the previous state, and the second collection view is bound, only a few of the rows are shown, even though this second collection contains the required number rows.



The above code shows how the ItemsSource is bound, the IsExpanded property maintains the state is a boolean, and DataContext is the viewModel with the two collection view properties.

The two collectionview sources are SummaryView and SortedView. When the control is first loaded, the summary view is shown, when expanded the SortedView is shown. 

Additionally, if the SummaryView is empty, then the Visibility of the treelistview is set to collapsed. In the expanded view the treelistview, the visibility however works fine.

Thank You

Hello,

In the scenario that we have, we need to drag items from a TreeView onto an image.  The image is a map and has a couple of collections items added to display on top of the map.  I am using the RadDragAndDropManager to drop items onto the map.

Here is the XAML for defining the target:

....
<Grid x:Name="mapGrid"
                  Visibility="{Binding Text, ElementName=mapFilenameTextBox, Converter={StaticResource StringEmptyToVisibilityConverter}}"
                  HorizontalAlignment="Center" VerticalAlignment="Center"
                  Margin="2">
                <Image x:Name="mapImage"
                       Source="{Binding MapFilename, Mode=OneWay}"
                       Stretch="Uniform" StretchDirection="Both" SizeChanged="mapImage_SizeChanged" Loaded="mapImage_Loaded"/>


                <ItemsControl x:Name="mapSymbolLabelsItemsControl"
                              ItemsSource="{Binding MapSymbolLabels}">
                    <ItemsControl.ItemsPanel>
                        <ItemsPanelTemplate>
                            <Canvas>
                                <Canvas.Background>
                                    <SolidColorBrush Opacity="0"/>
                                </Canvas.Background>
                            </Canvas>
                        </ItemsPanelTemplate>
                    </ItemsControl.ItemsPanel>
                    <ItemsControl.ItemContainerStyle>
                        <Style>
                            <Setter Property="Canvas.Top" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=Top}" />
                            <Setter Property="Canvas.Left" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=Left}" />
                            <Setter Property="Label.ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=LabelName}" />
                        </Style>
                    </ItemsControl.ItemContainerStyle>
                </ItemsControl>


                <ItemsControl x:Name="mapAreaItemsControl"
                              AllowDrop="True"
                              Drop="mapAreaItemsControl_Drop"

                              GiveFeedback="mapAreaItemsControl_GiveFeedback"
                              ItemsSource="{Binding MapSymbols}">
                    <ItemsControl.ItemsPanel>
                        <ItemsPanelTemplate>
                            <Canvas x:Name="mapCanvas">
                                <Canvas.Background>
                                    <SolidColorBrush Opacity="0"/>
                                </Canvas.Background>
                            </Canvas>
                        </ItemsPanelTemplate>
                    </ItemsControl.ItemsPanel>
                    <ItemsControl.ItemContainerStyle>
                        <Style>

                        </Style>
                    </ItemsControl.ItemContainerStyle>
                    <ItemsControl.ContextMenu>
                        <ContextMenu>
                            <MenuItem Header="{l:Translate DeleteContextMenuItem}" Command="{Binding DeleteSelectedMapSymbolsCommand}"/>
                        </ContextMenu>
                    </ItemsControl.ContextMenu>
                </ItemsControl>
            </Grid>
...

In the Constructor of the view, I set up the DragAndDropEvents:

RadDragAndDropManager.SetAllowDrop(mapAreaItemsControl , true);

RadDragAndDropManager.AddDropQueryHandler(mapAreaItemsControl, new EventHandler<DragDropQueryEventArgs>( OnDropQuery ) );
RadDragAndDropManager.AddDropInfoHandler(mapAreaItemsControl, new EventHandler<DragDropEventArgs>( OnDropInfo ) );

What I am seeing with this is that OnDropQuery fires once and I set the query result to true to enable the drop.

private void OnDropQuery( object sender, DragDropQueryEventArgs e )
{    
    e.QueryResult = true;
    e.Handled = true;
}

I expect that the drag status should be allowed at this point, but its being set to DropImpossible.

I did notice that the OnDropInfo event is being fired twice - the first time, the drag status is DropPossible, but the second time, the drag status is DropImpossible.  The sender both times is the items control and this happens weather the items control is empty or not.  I have tried several combinations of allowing drop to the containing grid, the image, the item control and all of them, but the result is the same.

Hi All,
    I have an issue where I am binding my ViewModel to the TreeView and using a hierarchical data template to allow a self referencing list of items.

I have got this all working fine - however, when I add a new item to the source list, it causes the itemssource on the treeview to be re-evaluated. This in turn calls the converter (which is using a linq query to find the top level of the tree and children).

I think that by calling this converter, the TreeView is losing track of which items were expanded because when the control refreshes, the TreeView is collapsed

This is my converter code (pretty simple):

public object Convert(object value, Type targetType, object parameter, CultureInfo culture)

       {

           var item = value as Structure;

           var items = value as SturctureCollection;

 

           if (items != null)

           {

               return items.Where(i => i.ParentID == 0);

           }

           else if (item != null)

           {

               var parent = (item.Parent as StructureCollection);

 

               return parent.Where(i => i.ParentID == item.ID);

           }

 

           return null;

       }

Any idea if this is easily recitified with an option on the control? If not I assume I will need to track which items are expanded (I was thinking about just putting the IDs in a list and iterating), if so which event is best to use when the underlying itemssource is re-evaluated?

Thanks,
Charles

We have started using the Telerik RadControls in our latest WPF application, but our test team are having a few issues when using QTP 11.0 to create automated UI tests for some of the controls.

Specifically, when a RadComboBox is made editable, they can't get QTP to enter text with the 'type' command (which works with a regular WPF ComboBox) as it complains it can't focus on the control. Also with the RadGridView control it doesn't seem to pick the grid up at all, just individual cells.

Has anyone else had any luck using QTP with the WPF RadControls? Any tips or QTP plugins that anyone is aware of?

Thanks for any help,

John
