Hi, I'm trying to Bind the GeoBound Properties to my ViewModel, and it is working properly for the GeoBoundsNW and GeoBoundsSE for the RadMap properties, but when I try and bind the GeoBoundsNW and GeoBoundsSE properties inside the UriImageProvider, they are never updated.

<telerik:RadMap x:Name="radmap" Margin="0" GeoBoundsNW="{Binding GeoBoundsNw, Mode=TwoWay}" Center="30.402077, -81.524325" GeoBoundsSE="{Binding GeoBoundsSe, Mode=TwoWay}" MinZoomLevel="13" MaxZoomLevel="20" ZoomLevel="16" NavigationVisibility="Collapsed" ZoomBarPresetsVisibility="Collapsed" DataContext="{Binding CurrentMap}" MouseClickMode="None">

<telerik:RadMap.Providers>

<telerik:UriImageProvider GeoBoundsNW="{Binding GeoBoundsNw, Mode=TwoWay}" GeoBoundsSE="{Binding GeoBoundsSe, Mode=TwoWay}" GeoBounds="{Binding GeoBounds, Mode=TwoWay}" Uri="my uri" telerik:MapLayer.ZoomRange="13,20" MinZoomLevel="13" MaxZoomLevel="20" />

</telerik:RadMap.Providers>

</telerik:RadMap>

When I debug and step through, the RadMap itself is binding properly, just the UriImageProvider properties. Any ideas?

Parent expander (ToggleButton) color style

I have had success setting colors of most things on the GanttView, but the expander toggle button and GanttPresenterSplitter continue to elude me. I can find it with Snoop and see the Path object, modify it, and see the color change. Every combination of style change, however, has failed to work on load. I even went into blend to extract the control template, but nothing there is copy-able (extract-able) like it is with RadGridView; I just get a blank template. Any thoughts would be appreciated.

I have read over this document http://www.telerik.com/help/wpf/radganttview-styles-and-templates-overview.html, and it talks about the ExpandToggleeButton (ToggleButton) and GanttPresenterSplitter as stylable. They either just don't want to play nice or they need an odd style designation.

The general gist is everything is transparent to common background (which is a dark gradient), over which lies white text and controls; except for the splitter that I wanted solid black; of course it's white

This was tested under 2013 Q2 (6/11) release.

Any thoughts/help would be appreciated.

DataFormValidationSummary no longer displaying in 2013 Q2 611

Hi,
I have been using the DataFormValidationSummary outside of the DataForm within my own UserControl. The version I've been using is 2012 Q3 11/29 and it has worked beautifully. I recently upgraded to 2013 Q2 6/11 and now the DataFormValidationSummary no longer displays. Hopefully you can identify why this might occur, as I would hate to have to move back to the working version.
Thanks in advance,
Steve

Default Setting for GridViewCheckBoxColumn

Hi Team,
I'm utilizing the GridView control, and everything is working great. However one thing I'm noticing is when binding to the GridViewCheckBoxColumn, and after the grid loads, the cells don't show the actual checked or unchecked value, but just a square with a minus symbol in it. I have to activate the cell to get it to show if it's checked or not. How can I get it to show the cells state without clicking on it? Or is this a binding problem? Everything else is working great.

See screenshot.

Thanks,
Ryan

Moving shape from one container to another causes "The items collection cannot be used together with the ItemsSource"

I'm using a RadDiagram, composed of 3 RadDiagramContainerShape's to represent a header/footer/body of a document. I'm using a custom RadDiagramShape. I was originally (with no ContainerShape's) binding the RadDiagram to a GraphSource. I've since switched and set the ItemsSource of each ContainerShape to an ObservableCollection in my ViewModel of a VM i've derived from NodeViewModelBase. I'm handing the drag/drop operations as well. I am able to drag an item and drop it in a container, and update the ObservableCollection to get the Container to update. However, when I drag an item from one Container to the other, I get an exception stating:

"The Items collection cannot be used together with the ItemsSource. Please set the ItemsSource to null first."

I can see in the call stack that the observable collection was modified, resulting in this.

Can anyone help me out with this?

Thanks,
Steve

Disabling RowReorderBehavior?

I'm trying to bring an app that was written against 2012.3.1017.40 forward, and I've run up against the dropping of RadDragAndDropManager. So I'm trying to write our stuff to use the new DragDropManager. And I'm having a problem.

We have a grid on which we want drag-and-drop reordering only sometimes. So I've bound RowReorderBehavior.IsEnabled to a property on my viewmodel. And here's the odd thing - it only works to turn RowReorderBehavior on, not off.

I can trace, in the debugger, the property as its value is set, and I can see it raising INotifyPropertyChanged. And if I'm setting it to true, I then trace through RowReorderBehavior.OnIsEnabledPropertyChanged(). But if I set it to false, I'm still raising INotifyPropertyChanged, but RowReorderBehavior.OnIsEnabledPropertyChanged() is never called.

I can replicate this in the Q3 2012 Row Reorder demo.

To RowReorderBehavior.cs, I add the following class:

public class SortingAllowed : INotifyPropertyChanged

{

public SortingAllowed()

{

this.allowSorting = false;

}

private bool allowSorting_;

public bool allowSorting

{

get { return this.allowSorting_; }

set

{

this.allowSorting_ = value;

OnPropertyChanged("allowSorting");

}

public event PropertyChangedEventHandler PropertyChanged;

private void OnPropertyChanged(string propertyName)

{

if (PropertyChanged != null)

PropertyChanged(this, new PropertyChangedEventArgs(propertyName));

}

Then in Example.xaml, I add a static instance to Grid.Resources, create a couple of row definitions, set a checkbox in row 0, move the RadGridView to row 1, then bind Checkbox.IsChecked and RadGridView's RowReorderBehavior.IsEnabled to the static resource:

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="auto" />

<RowDefinition Height="*" />

</Grid.RowDefinitions>

<Grid.Resources>

<local:SortingAllowed x:Key="sortingAllowed" />

<Style TargetType="telerik:GridViewRow"

x:Key="DraggedRowStyle"

BasedOn="{StaticResource GridViewRowStyle}">

<Setter Property="telerik:DragDropManager.AllowDrag"

Value="True" />

</Style>

</Grid.Resources>

<StackPanel Grid.Row="0" Orientation="Horizontal">

<CheckBox IsChecked="{Binding Source={StaticResource sortingAllowed}, Path=allowSorting}">Allow sorting</CheckBox>

</StackPanel>

<telerik:RadGridView

Grid.Row="1"

x:Name="RadGridView1" GroupRenderMode="Flat"

ShowGroupPanel="False" CanUserResizeRows="True"

ItemsSource="{Binding Customers}"

RowStyle="{StaticResource DraggedRowStyle}"

AllowDrop="True"

CanUserSortColumns="False"

local:RowReorderBehavior.IsEnabled="{Binding Source={StaticResource sortingAllowed}, Path=allowSorting}"

telerik:ScrollingSettingsBehavior.IsEnabled="True"

telerik:ScrollingSettingsBehavior.ScrollAreaPadding="30"

telerik:ScrollingSettingsBehavior.ScrollStep="24"

telerik:ScrollingSettingsBehavior.ScrollStepTime="00:00:00.05">
