IconTemplateSelector

The RadFilePathPicker control exposes an IconTemplateSelector, which allows you to easily change the displayed icon depending on the FilePath.

FilePathPickerIconTemplateSelector

The default value of the IconTemplateSelector property of the control is an instance of FilePathPickerIconTemplateSelector. It exposes the following properties:

  • EmptyTemplate

    The EmptyTemplate is displayed, when the FilePath property of the control is null or empty as demonstrated in Figure 1.

  • NonEmptyTemplate

    The NonEmptyTemplate is displayed, when the FilePath property of the control is not empty as demonstrated in Figure 2.

In order to hide the icon, you can set the IconVisibility property of the control to Collapsed.

Custom FilePathPickerIconTemplateSelector

Example 1 demonstrates how to create a custom FilePathPickerIconTemplateSelector and display red/green Rectangle elements depending on whether the FilePath is empty.

Example 1: Custom FilePathPickerIconTemplateSelector

<StackPanel> 
    <StackPanel.Resources> 
        <DataTemplate x:Key="MyEmptyTemplate"> 
            <Rectangle Fill="Red" /> 
        </DataTemplate> 
 
        <DataTemplate x:Key="MyNonEmptyTemplate"> 
            <Rectangle Fill="Green" /> 
        </DataTemplate> 
        <telerik:FilePathPickerIconTemplateSelector x:Key="MyItemTemplateSelector" EmptyTemplate="{StaticResource MyEmptyTemplate}" NonEmptyTemplate="{StaticResource MyNonEmptyTemplate}" /> 
    </StackPanel.Resources> 
    <telerik:RadFilePathPicker IconTemplateSelector="{StaticResource MyItemTemplateSelector}" /> 
</StackPanel>
