Alternative for handling context menu click event in RadTreeView

Hi

My RadTreeView's are in a HiearchicalDataTemplate so the number of TreeViews is not known at design time.

I need to handle the ContextMenu's click event on a RadTreeViewItem but obviously I cannot just write RadTreeView.AddHandler

Does anyone have an alternative idea?

Thanks.

Custom Sorting of GridView with DataPager



private

void gridView_Sorting(object sender, GridViewSortingEventArgs e)

{

try

{

if (schedules == null)

{

e.Cancel = true;

return;

}

if (e.OldSortingState == SortingState.Ascending)

{

e.NewSortingState = SortingState.Descending;

schedules = schedules.OrderByDescending(s => s.Role).ThenBy(s => s.Name).ToList();

}

else if (e.OldSortingState == SortingState.Descending)

{

schedules = schedules.OrderByDescending(s => s.Name).ToList();

e.NewSortingState = SortingState.None;

}

else

{

e.NewSortingState = SortingState.Ascending;

schedules = schedules.OrderBy(s => s.Role).ThenBy(s => s.Name).ToList();

}

this.radDataPager.Source = schedules;

//e.DataControl.ItemsSource = this.radDataPager.Source; // replaced by the next line which is the same thing.

this.gridView.ItemsSource = this.radDataPager.Source;

this.gridView.Items.Refresh();

this.radDataPager.PageIndex = 0;

e.Cancel = true;

}

catch (Exception ex)

{

txtStatus.Text = "Erorr in gridView_Sorting:"+ex.Message;

}

Custom Sorting (routine shown above) of GridView with DataPager does not seem to work.
It shows sorted items on the current page but it does not navigate to another page.

Can you provide small sample code that works?

Thanks.

Item bindings not working

I am using version 2010.3.1110.40.

I have a RadTransitionControl that switches between two usercontrols through the bound content property. The switching works fine, however I have noticed that the top level bindings in both the usercontrols are not being set. To get things to work I have to set the binding in the code in the loaded event. I have even set a breakpoint on the get part of the bound collection and saw that it is not read at all. However, if I take the same usercontrol and place it by itself in the xaml then the breakpoint is hit during the xaml loading as it should be.

Drag and drop onto a floating pane

Hi

I've got an app that makes extensive use of the RadDocking system. I'm implmenting some drag and drop functionality, and this works fine when dropping an item onto a docked pane, but not onto a floating pane. Is this a known bug?

If so, when is it due to be fixed?

Thanks

Is it possible to add a few extra controls to the ScheduleView toolbar?

Is there a way to add extra controls to the ScheduleView toolbar (where "Month", "Week", "Day" buttons are shown) ? I would like to add a combobox to help drive the behavior of the schedule. I know I can add this above the ScheduleView but I am trying to conserve on space.

Thanks,
Rod

RADMAP control for WPF always sets ZoomLevel to 1 when using SetView()

Hi,

   I'm using RADMap control for WPF to plot the pins based on set of Lats and Longs. But, i need the Optimum Zoomlevel to display in Map. For this i use Setview() method of the rad map. By doing this i always get the Zoomlevel to 1. But, when i click on the button event, the Zoomlevel is setting correctly even if the debug says Zoomlevel =1. Please find my below code and let me know how should i proceed.

MainWindow.xaml
==============
<Window x:Class="RadMapControlStudy.MainWindow"
xmlns=http://schemas.microsoft.com/winfx/2006/xaml/presentation
xmlns:x=http://schemas.microsoft.com/winfx/2006/xaml
Title="MainWindow" Height="600" Width="600" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">
<Grid>
<telerik:RadMap Height="500" HorizontalAlignment="Left" Margin="3,0,0,0" Name="radMap1" VerticalAlignment="Top" Width="500">
<telerik:InformationLayer x:Name="layer">
</telerik:InformationLayer>
</telerik:RadMap>
<Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="503,282,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
</Grid>
</Window>

MainWindow.xaml.cs
==================
namespace RadMapControlStudy
{
public partial class MainWindow : Window
{
    Location lc1 = new Location(28.066600, -82.381600); //Some LatLong
    Location lc2 = new Location(28.066890, -82.381876); //Some LatLong

public MainWindow()
{
    InitializeComponent();
    radMap1.Provider = new BingMapProvider(MapMode.Road, true, "KeyValue");
    layer.Items.Add(lc1);
    layer.Items.Add(lc2);

    LocationRect lr = new LocationRect(lc1, lc2);
    radMap1.SetView(lr);
}

private void button1_Click(object sender, RoutedEventArgs e) //Zoom seems to be working fine when you click the button
{
LocationRect lr1 = new LocationRect(lc1,lc2);
radMap1.SetView(lr1);
}
