References (for example Telerik.Windows.Controls, Telerik.Windows.Data e.t.c) can not be found and so can't be added to the developed application.

We had bought a licence for Dev Craft Complete for WPF library and began use it since spring of 2016. This library has been installed on my computer. Сurrently the license is valid. But when I try (in my application) to add reference to any DLL then this reference is not found. For example, if I try to add reference to Telerik.Windows.Controls then it hasn't been found e.t.c. Why does this situation has place? In this situation I can't write the application using Telerik Dev Craft Complete. Please help me.

AsyncFilteringBehaviour

Hi All,

I am trying to implement an AutoCompleteBox dynamically in C#, everything loads great but I have ~15,000 records to filter and it takes a few seconds to load. I have read that this can be improved with AsyncFilteringBehaviour but only ever see reference to how this is set in XAML.

I have tried to simply set the following, but am obviously missing something because it doesn't filter at all when I do this:

myAutoCompleteBox.FilteringBehavior = new AsyncFilteringBehavior();

Any help would be appreciated!

Set RadToolTipService properties globally

Hello,

as mentioned in the title, I would like to set some of RadToolTipServices' properties globally. I tried to set them as follows:

<Style x:Key="RadToolTipStyle" TargetType="telerik:RadToolTip">

<Setter Property="Placement" Value="Top"/>

<Setter Property="HorizontalOffset" Value="10"/>

<Setter Property="VerticalOffset" Value="10"/>

...

</Style>

<Style TargetType="telerik:RadToolTip" BasedOn="{StaticResource RadToolTipStyle}"/>

but this had no effect on the positioning. Do I have to set those properties elsewhere or is this a bug?
Currently, I got the desired result by adjusting the margin in the template.

Best regards

How to bind PropertyGrid to GridView selectedItem in code?

I have a GridView and a PropertyGrid both created in code not XAML.
Now I try to bind the selected item of the GridView to the PropertyGrid also via code and not XAML.
I tried something like this:

Binding propGridBinding = new Binding("SelectedItem");

propGridBinding.ElementName = "myTreeListView"; // assuming this is the name of the GridView

propertyGrid.Item = propGridBinding;

But when I try to run this code I get an error message like this:
An unhandled exception of type 'System.NotSupportedException' occurred in System.dll
Additional information: 'CultureInfoIetfLanguageTagConverter' is unable to convert '(null)' to 'System.String'.

I even get the same type of error if I just try to bind the PropertyGrid to a visual element to be able to view and edit its properties.

I must be missing something.

Any help is very much appreciated.

Thanks,
Markus

Custom control validation on dependency property using masked input

Hi

We have implemented a validation through data annotation on a RadMaskedTextInput using this link: http://docs.telerik.com/devtools/wpf/controls/radmaskedinput/features/validation/regex

We are having an issue when we are implementing it with a custom control.

In the provided solution when RadMaskedTextInput, one is provided through the control and the other one is directly in the MainWindow.

The first RadMaskedTextInput (from the custom control) does not validate the data.

The second RadMaskedTextInput is validating the data when we are directly typing in it.

we suspect that it is related to the fact that we are binding a dependency property

How can we modify the custom control to trigger the validation on the property?

Thank you for your help

Alexandre
