Usage
The KeyValueList controls allows to declare a complex parameter type from within XAML markup. It can hold any number of KeyValueParameter elements, where each consists of a string Key and and associated value.
Example
The following example shows how to use the control with two parameters in conjunction with the NavigateToGuidCommand. The first parameter specifies the Guid of the target document and the second parameter specifies the HotSpot that should be highlighted on that very document. This example needs a namespace declaration xmlns:ctrls="using:UBIK.WinX.Controls"
<Button.CommandParameter>
<ctrls:KeyValueList>
<ctrls:KeyValueParameter Key="Guid" Value="c9ad0e93-395a-4b4e-a526-fb5d5e42f8ff" />
<ctrls:KeyValueParameter Key="HotSpot" Value="b9e855f9-d3be-4b60-b4e3-19398f5925b5" />
</ctrls:KeyValueList>
</Button.CommandParameter>
</Button>
To use a Binding in the KeyValueParameter, the following logic has to be used, instead of applying the binding directly on the Value property
<Button.CommandParameter>
<uc:KeyValueList>
<uc:KeyValueParameter Key="Parent" Value="{Binding Tag, ElementName=CreateButton}"/>
<uc:KeyValueParameter Key="Type" Value="21fc990a-d064-4bee-8d48-3293351f827a"/>
</uc:KeyValueList>
</Button.CommandParameter>
</Button>
Parameters
KeyValueParameter can be added as child objects to an KeyValueList control. Each parameter object needs a unique Key and a Value, where the latter can be either a constant or dynamic value supplied through a binding.
