Hi, my maskedtextinput is only allowed to have capitalized characters. May I ask how should I do that? I've enforced it on the model side but it moves the next available entry to the front of the masked instead of always keeping it maintained on the right.

Export and print RadGridView in XBAP

Is it possible to export grid data in partial trust XBAP application? I know that SaveFileDialog is not permited in partial trust, but Silverlight has his own SaveFileDialog and it works.

Next question. We want to print grid but the orginal form of print view is hopeless. There are not margins, some data is cutted, there are not title. Is it possible to override default print? We want to use the same filters and columns like in grid when print is generating.

Speed GridView Printing

Hi, I'm using the same approach as a demo I came across on a forum post. It works well if the # of rows is small, but once you start to add hundreds of rows, the performance goes down dramatically. Any idea how to solve this?

Demo can be found here. It's almost like yours except with a for loop creating a larger dataset. Takes over 5 mins to get the print.

RadPropertGrid isn't setting the annotation "DisplayName" of properties while using PropertySetMode for showing common properties of multiple objects

I am using you own example in Setting PropertSets

In this I've set DisplayName of FillColor property, but it don't get it's this specified display name, but rather it shows the property name.

MainWindow.xaml

<Grid>

<Grid.Resources>

<local:ViewModel x:Key="vm" />

</Grid.Resources>

<telerik:RadPropertyGrid DataContext="{StaticResource vm}"

Item="{Binding Shapes}"

PropertySetMode="Intersection"/>

</Grid>

ViewModel.cs

public class ViewModel

{

public IEnumerable<object> Shapes

{

get

{

return new List<object>()

{

new Ellipse()

{

Center = new Point(1,1),

FillColor = Colors.Red,

RadiusX1 = 4, RadiusX2 = 2

},

new RegularPolygon()

{

Center = new Point(3,2),

FillColor = Colors.Blue,

CornersCount = 3,

SideLength = 10

}

};

}

public class Ellipse

{

[DisplayName("Fill Color")]

public Color FillColor { get; set; }

public double RadiusX1 { get; set; }

public double RadiusX2 { get; set; }

public Point Center {

get;

set; }

}

public class RegularPolygon

{

public int CornersCount { get; set; }

public Color FillColor { get; set; }

public Point Center {

get;

set; }

public double SideLength { get; set; }

}

Kindly suggest me it's solution.

Show spinner/progress while data is loading

I am binding the GridView to a ViewModel that is responsible for loading the data from my repository. I would like to show a spinner control while the data is being loaded. Let's suppose I have a property on my ViewModel named DataLoading. I know I can accomplish this with a style, but I'm not sure which element of the GridView I should apply the style to.

How can I accomplish this with the GridView? I can easily hide the whole GridView and show a spinner, but instead I'd like to replace the area in which rows are presented with a spinner.

Thanks,

Mike

Docking Binding References

Hi Telerik,

We have a RadDocking control in a child control that resides within a RadDocking control in a parent control.

The parent control contains a RadDocking control which encompasses a Tab control, and the child control resides in one of these Tab controls, where the RadDocking control resides in another TabControl inside the child control. The parent and child controls each have their own Views and VMs.

When binding 'SelectedItem' in myDatagrid, we receive the following binding error:

Cannot find source for binding with reference 'ElementName=myDatagrid, RelativeSource={RelativeSource=Self}'. BindingExpression:Path=SelectedItem; DataItem=null; target element is 'InvokeCommandAction' (HashCode=57688201); target property is 'CommandParameter' (type 'Object')

This error disappears and we are able to bind to 'SelecteItem' only when we remove the 2nd (second) RadDocking control within the parent.

Please see attached diagram for visual reference.

Could you please advise?

Kind regards

[Solved] Change color of the spinner

Hi, I would like to change the color of my BusyIndicator. I have been able to change the background and the stroke but I can't modify the "spinner" colors.

This is quite a simple question that have been answered several times but I don't understand how to implement the solutions I saw in my code. Maybe you will be able to explain me the solution for the following code:

<ControlTemplate x:Key="GridViewLoadingIndicatorTemplate" TargetType="{x:Type grid:GridViewLoadingIndicator}">

<Border x:Name="BusyIndicatorBackground" Background="#F1F1F1" Opacity="0">

<VisualStateManager.VisualStateGroups>

<VisualStateGroup x:Name="CommonStates">

<VisualState x:Name="Idle"/>

<VisualState x:Name="Loading">

<Storyboard RepeatBehavior="Forever">

<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="BusyIndicatorBackground" Storyboard.TargetProperty="Opacity">

<SplineDoubleKeyFrame KeyTime="0" Value="1"/>

</DoubleAnimationUsingKeyFrames>

<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="BusyIndicator" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[2].(RotateTransform.Angle)">

<SplineDoubleKeyFrame KeyTime="00:00:01" Value="180"/>

</DoubleAnimationUsingKeyFrames>

</Storyboard>

</VisualState>

</VisualStateGroup>

</VisualStateManager.VisualStateGroups>

<Path x:Name="BusyIndicator"

Stretch="Fill"

Stroke="{TemplateBinding BorderBrush}"

StrokeThickness="{TemplateBinding BorderThickness}"

Fill="{TemplateBinding Background}"

Margin="{TemplateBinding Padding}"

HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"

VerticalAlignment="{TemplateBinding VerticalContentAlignment}"

Width="36"

Height="36"

Data=

"M18,5.0000002 C10.820298,5 5,10.820298 5.0000002,18 5,25.179701 10.820298,31 18,31 25.179701,31 31,25.179701 31,18 31,10.820298 25.179701,5 18,5.0000002 z M18,0 C27.941126,0 36,8.0588746 36,18 36,27.941126 27.941126,36 18,36 8.0588746,36 0,27.941126 0,18 0,8.0588746 8.0588746,0 18,0 z"

<Path.RenderTransform>

<TransformGroup>

<ScaleTransform/>

<SkewTransform/>

<RotateTransform Angle="-180"/>

<TranslateTransform/>

</TransformGroup>

</Path.RenderTransform>

</Path>

</Border>

</ControlTemplate>

<Style x:Key="GridViewLoadingIndicatorStyle" TargetType="{x:Type grid:GridViewLoadingIndicator}">

<Setter Property="Template" Value="{StaticResource GridViewLoadingIndicatorTemplate}"/>

<Setter Property="Background" Value="{StaticResource GridView_LoadingIndicatorBackground}"/>

<Setter Property="BorderBrush" Value="{StaticResource GridView_LoadingIndicatorBorder}"/>

<Setter Property="BorderThickness" Value="1"/>

<Setter Property="Padding" Value="0"/>

<Setter Property="VerticalContentAlignment" Value="Center"/>

<Setter Property="HorizontalContentAlignment" Value="Center"/>

</Style>

Thank you,
