Run Demo

The textual content of the selected region is stored in the SelectedHtmlText property. The code below copies this property’s value to the clipboard when a user presses Ctrl+C:

C#

void OnWinExplorerViewKeyDown(object sender, System.Windows.Forms.KeyEventArgs e) {
    if(Control.ModifierKeys.HasFlag(Keys.Control) && e.KeyCode == Keys.C) {
        var text = winExplorerView1.SelectedHtmlText;
        if(!string.IsNullOrEmpty(text))
            Clipboard.SetText(text);
    }
}

VB.NET

Private Sub OnWinExplorerViewKeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs)
    If Control.ModifierKeys.HasFlag(Keys.Control) AndAlso e.KeyCode = Keys.C Then
        Dim text = winExplorerView1.SelectedHtmlText
        If Not String.IsNullOrEmpty(text) Then
            Clipboard.SetText(text)
        End If
    End If
End Sub

When users drag the mouse pointer to select a portion of text, button captions, images, and other HTML elements along the way are also selected. Use the user-select CSS property to prevent unwanted HTML elements from being selected when the AllowContentSelection property is enabled.

<div class="button unselectable">Cancel</div>

.unselectable { user-select: none; }

Use the user-select CSS property to enable selection for individual elements if the AllowContentSelection property is set to DefaultBoolean.Default or DefaultBoolean.False.

.selectable { user-select: all; }
.selectableText { user-select: text; }
