Selecting Multiple Files

FilePicker for WPF and Silverlight allows users to select multiple files at run time, though this option is not selected by default. At run time, users can only select one file at a time by default – you can allow users to select multiple files by setting the Multiselect property to True, for example see the steps below.

In XAML
In Code
At Design Time

To set the Multiselect property add Multiselect="True" to the <c1:C1FilePicker> tag so that it appears similar to the following:

XAML	Copy Code
<c1:C1FilePicker HorizontalAlignment="Left" Margin="112,36,0,0" Name="C1FilePicker1" VerticalAlignment="Top" Width="161" Multiselect="True" />

To set the Multiselect property, add the following code to your project:

Visual Basic	Copy Code
Me.C1FilePicker1.Multiselect = True

C#	Copy Code
this.c1FilePicker1.Multiselect = true;.

To set the Multiselect property at design time, complete the following steps:

Click the C1FilePicker control once to select it.
Navigate to the Properties window and locate the Multiselect item.
Check the check box next to the Multiselect item.

This will set the Multiselect property to allow users to select multiple files at run time in the OpenFileDialog dialog box.
