   <ComboBox Text="SelectOnFocus ComboBox" IsEditable="True">
                <p:Attached.Operations>
                    <p:EventHandler Path="Loaded">
                        <p:CallHandler>
                            <p:CallHandler.Path>
                                GotFocus => @Sender.Template.FindName("PART_EditableTextBox", @Sender).SelectAll()
                            </p:CallHandler.Path>
                        </p:CallHandler>
                    </p:EventHandler>
                </p:Attached.Operations>
            </ComboBox>

获得焦点时候全选文本

   <TextBox Text="SelectOnFocus TextBox"  x:Name="LIKE_textBox">
                <p:Attached.Operations>
                    <p:CallHandler Path="GotFocus => @AssociatedObject.SelectAll()"/>
                </p:Attached.Operations>
            </TextBox>
