RadScheduleView + TimeBar bind to ViewModel

Hi @ All,

is there any tutorial how to bind a viewmodel to a TimeBar + ScheduleVIew? In the Demo of telerik there is the DataContext generated in xaml.

<UserControl.DataContext>

<example:RandomGeneratorViewModel RandomSeed="123" StartTime="1/1/2011 12:00:00 AM"

EndTime="12/31/2011 11:59:59 PM" CurrentTime="6/5/2011 10:00:00 AM">

<example:RandomGeneratorViewModel.Lipsum

>Pellentesque dapibus congue neque, eu bibendum dui elementum sed. Integer porta suscipit venenatis. Quisque gravida, est in eleifend dignissim, sapien dui euismod erat, pulvinar eleifend leo risus sit amet massa. Suspendisse sit amet metus ut lorem hendrerit molestie sed eu justo. Mauris eu tristique ipsum. Vivamus sodales venenatis nibh quis suscipit. Nulla facilisi. Pellentesque purus risus, hendrerit at venenatis sit amet, fringilla et arcu. Donec luctus tincidunt iaculis. Integer sapien tortor, lacinia et mattis vitae, facilisis at massa. Vestibulum scelerisque euismod posuere. Etiam sed velit non velit hendrerit rutrum eget sed risus. Nullam blandit congue dapibus.

Vivamus adipiscing sodales quam, et suscipit mi adipiscing sollicitudin. Vestibulum volutpat dui in massa scelerisque accumsan. Proin ac odio non nisi ornare semper. Morbi sapien ante, pulvinar quis lobortis in, viverra porttitor lorem. Aenean pellentesque euismod risus eu porttitor. Donec lobortis volutpat suscipit.</

How to modify the text of controls on ScheduleView?

I'm developing a project with ScheduleView. When I click "New Appointment" RibbonButton, a RadWindow named " Appointment - Untitled" was opened. Then my question is, how can I modify these text(or content) of controls on the windows, because I want to make the project into multiple languages.

Thanks.

Bind FilterDescriptor Value to TreeView selected item

Good morning,

I'm trying to bind a FilterDescriptor value to the tag value of a treeview item. Is this possible?

I have the following code but it doesn't work:

<telerikData:FilterDescriptor Member="ParkID" Operator="IsEqualTo" Value="{Binding ElementName=treeParks, Path=SelectedItem.Tag}" />

Thank you for your time,

XmlDocument Binding - Need Multi-Level XmlNode Support From RadGridView

I need to bind this document to the RadGridView and have a child data template for each row where the parametercollection node exists.

<MethodInformation>

<tenantid>0</tenantid>

<namespaceName>BusinessServer.BusinessPolicies.ServiceContractsComponent</namespaceName>

<className>ServiceContractsBusPolicyMgr</className>

<methodName>ExtractVouchersAndPostToInvoice</methodName>

<runAsynchronously>Y</runAsynchronously>

<autoRestart/>

<parameters>

<parameter>

<name>contractsequencein</name>

<value/>

</parameter>

<parameter>

<name>subsequencein</name>

<value/>

</parameter>

<parameter>

<name>billingdatein</name>

<value/>

</parameter>

<parameter>

<name>requestclosedatein</name>

<value/>

</parameter>

<parameter>

<name>additionalparametersin</name>

<parametercollection>

<parameter>

<name>tablename</name>

<value/>

<name>columnname</name>

<value>posting_group</value>

<name>columnvalue</name>

<value>KL</value>

</parameter>

</parametercollection>

</parameter>

<parameter>

<name>theplaceidtobillin</name>

<value/>

</parameter>

<parameter>

<name>theinvoiceconsolidationruleidin</name>

<value/>

</parameter>

</parameters>

</MethodInformation>

The following code (where strXml variable is the xml as string above) doesn't support viewing the parameters inside of parametercollection element.

      

XmlDataProvider xProviderResource =

new

XmlDataProvider();

XmlDocument xParameterDoc =

new

XmlDocument();

xParameterDoc.LoadXml(strXml);      

xProviderResource.IsAsynchronous =

false

;          

xProviderResource.Document = xParameterDoc;    

xProviderResource.XPath =

"MethodInformation/parameters/parameter"

;   

IEnumerable<XmlNode> iXnodeEnum = xProviderResource.Data

as

IEnumerable<XmlNode>;

ObservableCollection<XmlNode> obsElementCollection =

new

ObservableCollection<XmlNode>(iXnodeEnum);

radGridView2.ItemsSource = obsElementCollection;

We have an ID with telerik support. My company purchased both WPF and ASP.NET AJAX controls. If someone can provide an email address I will send the ID directly to them so I can get a higher priority support.

Value under 0 when AxisY.Minimum is positive

Was working with some data and I noticed some bug when the YValue of a point is negative while the minimum of an axis is positive.

I made a demo to reproduce the bug

xaml:

<Grid>

<Grid.RowDefinitions>

<RowDefinition />

<RowDefinition Height="Auto"/>

</Grid.RowDefinitions>

<telerik:RadChart ItemsSource="{Binding Points}" >

<telerik:ChartArea.AxisX>

<telerik:AxisX MinValue="{Binding MinX}" MaxValue="{Binding MaxX}" AutoRange="False" Step="{Binding StepX}" />

</telerik:ChartArea.AxisX>

<telerik:ChartArea.AxisY>

<telerik:AxisY MinValue="{Binding MinY}" MaxValue="{Binding MaxY}" AutoRange="False" Step="{Binding StepY}" StripLinesVisibility="Collapsed"/>

</telerik:ChartArea.AxisY>

</telerik:ChartArea>

</telerik:RadChart>

<Slider Grid.Row="1" Value="{Binding MinY, Mode=TwoWay}" Minimum="-10" Maximum="10" SmallChange=".5" LargeChange="5"/>

</Grid>

ViewModel:

public class ViewModel : INotifyPropertyChanged

{

private double _minY = -10;

private double _maxY = 50;

private double _stepY = 10;

private double _minX = 0;

private double _maxX = 50;

private double _stepX = 10;

public ViewModel()

{

MaxY = 50;

StepY = 10;

MinX = 0;

MaxX = 50;

StepX = 10;

Points = new ObservableCollection<Tuple<double, double, double, double>>();

Random r = new Random();

Points.Add(Tuple.Create(.1, -8d, 1d, 5d));

for (double i = 20; i < 50; i += 4)

{

Points.Add(Tuple.Create(i, i - 8, (i - 5) + (r.NextDouble() * 9 - 4.5), i - 25));

}

public ObservableCollection<Tuple<double, double, double, double>> Points { get; private set; }

public double MinX { get; private set; }

public double MaxX { get; private set; }

public double StepX { get; private set; }

public double MinY

{

get

{

return _minY;

}

set

{

_minY = value;

OnPropertyChanged("MinY");

}

public double MaxY { get; private set; }

public double StepY { get; private set; }

protected void OnPropertyChanged(string propertyName)

{

if (PropertyChanged != null)

{

PropertyChanged.Invoke(this, new PropertyChangedEventArgs(propertyName));

}

public event PropertyChangedEventHandler PropertyChanged;

}

The slider bar changes the Minimum of the AxisY and as soon as the minimum hit 0, you can see that the line are now rendered as if the YValue of the point was 0.

RadPanelBarItems with identical children

I posted the following in PITS, but I wanted to also post it here in hopes of finding an easy workaround or some sort of temporary solution to my problem.

If the first PanelBarItem has ever been expanded, selecting the second of the two identical children causes the first child to be selected instead. This is easily demonstrated with the following example:

<telerik:RadPanelBar Height="200">
<telerik:RadPanelBarItem Header="Parent A">
Child
</telerik:RadPanelBarItem>
<telerik:RadPanelBarItem Header="Parent B">
Child
</telerik:RadPanelBarItem>
</telerik:RadPanelBar>

This is just a simple example, but it happens independent of the number of RadPanelItems or children that exist; when the second of two identical children is selected the result will be that the first child is selected.

Any ideas?

DragDropManager might result: Error HRESULT E_FAIL has been returned from a call to a COM component.

while working with the Q3 11 controls, everything worked well with draging from the TreeView.

The current scenario is that we allow reordering of tree items, but we also allow dragging outside the tree.
When the dragged treeview item is being dragged over a specific control, we cancel the drag using:

Telerik.Windows.DragDrop.DragDropManager.AddQueryContinueDragHandler(solutionTree, solutionTree_QueryContinueDrag);

And then in the QueryContinueDrag do:

e.Action = DragAction.Cancel;

e.Handled = true;

And call (with a BeginInvoke) to a function on my classes that starts a DragDrop (using microsoft drag drop) with my own UI.

The exception happens after the drop.

All signs point to the fact that the exception comes from your code.
