[Solved] RadTileView and RadBook item dragging error

Hi, I am having an issue where if I add a RadBook as a Content template to a RadTileView, it throws an exception:

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in PresentationCore.dll

Additional information: The parameter value must be greater than zero.

This doesn't always happen but will if you move enough of them around. If I take out the book control it works fine. Any Ideas?

add a delete button only in small & normal view

Hello;

I use telerik tile view in our project.

We have customized the template to add a "remove button" in the header by editing the tileview template. The delete button is available in the different views (small, normal & large). We have been requested to set the button only in small & normal view. So, how can we remove the "delete button" from the large view only.

Thanks for your replies.

Best regards

[Solved] TrackBall Info Template Decimal Places

I'm trying to format the String output for my Series Trackball so that it only shows 2 decimal places. The code I have at the moment for my Template is as follows:

<telerik:RadCartesianChart.Resources>

<sys:String x:Key="CategoryFormat">Date: {0}</sys:String>

<sys:String x:Key="ValueFormat">Value: {0:n2}</sys:String>

<DataTemplate x:Key="seriesTrackBallInfoTemplate">

<StackPanel Orientation="Vertical">

<TextBlock Text="{Binding Path=MeasurementData.Category, StringFormat={StaticResource CategoryFormat}}" />

<TextBlock Text="{Binding Path=MeasurementData.Value, StringFormat={StaticResource ValueFormat}}" />

</StackPanel>

</DataTemplate>

</telerik:RadCartesianChart.Resources>

The type of MeasurementData.Value is Double.

I've tried various approaches and nothing seems to work.

Any suggestions?

Unfortunately when I try to bind the "ValueColour" property on my PointSeries style, for the Path style's Fill property, I get an invalid cast exception.

My ValueColour Property is of type String and I have tried using converters for both String to Color and String to SolidColorBrush and neither of them are working. The cast exception I get says:

Additional information: Unable to cast object of type 'System.Windows.Data.Binding' to type 'System.Windows.Media.Brush'.

However it works if I hard-code the colour with the value "Red" for example.

How do I make this data-bindable?
