Detailed Description

Provides a DataTemplate instance constructed in codebehind using FrameworkElementFactory.

Any public, non-static, non-abstract class that implements this interface can be specified for HotkeyActionSettingAttribute.DataTemplateProviderType.

To create an ITemplateProvider, first create a new class that implements it:

public class IntDataTemplateProvider : IDataTemplateProvider
{
    public DataTemplate ProvideDataTemplate()
    {
        // Create a TextBox (via a factory) and bind its Text property to the action setting's Value property:
        var textBoxFactory = new FrameworkElementFactory(typeof(TextBox));
        textBoxFactory.SetBinding(TextBox.TextProperty, new Binding("Value"));
 
        return new DataTemplate(typeof(int)) { VisualTree = textBoxFactory };
    }
}

You would then specify the IntDataTemplateProvider type in your HotkeyActionSettingAttribute:

[HotkeyActionSetting("SomeSetting", typeof(int), typeof(IntDataTemplateProvider))]

Member Function Documentation

◆ CanProvideDataTemplate()

bool VolumeControl.Core.ITemplateProvider.CanProvideDataTemplate ( Type valueType )

Checks if this ITemplateProvider instance can provide a DataTemplate for the specified valueType .

Parameters

valueType The value type of the action setting to display in the template.

Returns: true when this instance supports the valueType ; otherwise false.

◆ ProvideDataTemplate()

DataTemplate? VolumeControl.Core.ITemplateProvider.ProvideDataTemplate ( Type valueType )

Gets the DataTemplate instance to use for displaying an editor control for the action setting's value.

The returned DataTemplate will always be used with a DataContext of the Input.Actions.Settings.IActionSettingInstance instance for that action setting. Therefore, valid data binding paths can be relative to an Input.Actions.Settings.IActionSettingInstance instance, or absolute by directly specifying a binding Source.
A data binding path of "<see langword="Value"/>" will return the value instance of type HotkeyActionSettingAttribute.ValueType.
Return null to allow another data template to be selected.
