WPF watermark Mahaps with defined style












1















In my WPF application, I am trying to have watermark on my MahApps.Metro textbox to which I have set a custom style:



Style x:Key="TextBoxStyle" TargetType="{x:Type TextBox}">

            <Setter Property="VerticalAlignment" Value="Center" />

            <!--<Setter Property="BorderThickness" Value="1" />-->

            <Setter Property="Margin" Value="10 0 30 0" />

            <!--<Setter Property="BorderBrush" Value="SteelBlue" />-->

            <Setter Property="BorderThickness" Value="0.7" />

            <Setter Property="BorderBrush" Value="Gray" />

            <Setter Property="Background" Value="AliceBlue" />

            <Setter Property="Padding" Value="5" />

            <Setter Property="Validation.ErrorTemplate">

                <Setter.Value>

                    <ControlTemplate>

                        <DockPanel LastChildFill="true">

                            <Border Background="OrangeRed" DockPanel.Dock="right" Margin="5,0,0,0" 

                                Width="20" Height="20" CornerRadius="5"

                                ToolTip="{Binding ElementName=customAdorner, 

                                          Path=AdornedElement.(Validation.Errors)[0].ErrorContent}">

                                <TextBlock Text="!" VerticalAlignment="center" HorizontalAlignment="center" 

                                   FontWeight="Bold" Foreground="white" />

                            </Border>



                            <AdornedElementPlaceholder Name="customAdorner" VerticalAlignment="Center" >

                            </AdornedElementPlaceholder>

                        </DockPanel>

                    </ControlTemplate>

                </Setter.Value>

            </Setter>

            <Style.Triggers>

                </Trigger>

                <Trigger Property="IsFocused" Value="true">

                    <Setter Property="BorderBrush"  Value="{DynamicResource AccentColorBrush}"/>

                </Trigger>

            </Style.Triggers>

        </Style>

        <Style x:Key="MenuLevel2" BasedOn="{StaticResource MetroTabItem}" TargetType="{x:Type TabItem}">

            <Setter Property="mah:ControlsHelper.HeaderFontSize" Value="16" />

            <Style.Triggers>

                <Trigger Property="IsMouseOver" Value="true">

                </Trigger>

                <Trigger Property="IsSelected" Value="True">

                </Trigger>

            </Style.Triggers>

        </Style>







<TextBox Grid.Column="1" Grid.Row="1" x:Name="txtBox_updateWebSrvURL" Style="{StaticResource TextBoxStyle}"  

                                             Validation.Error="Validation_Error"

                                             Text="{Binding UpdateSourceTrigger=PropertyChanged, Path=webSrvURL,

                                             ValidatesOnDataErrors=true, NotifyOnValidationError=true}"  

                                             Controls:TextBoxHelper.Watermark="MyWatermark here!!!!/" />


If I remove the custom style the watermark is well applied. Any idea how I can enable the watermark but still use my custom style?

  • You need to include the watermark in your custom ControlTemplate.

  • Thanks for your proposal. It does the job but I see a side effect which is when a field is disabled the watermark is still visible on the top of the existing value. Have you got any idea how to fix this?

  • Hello, sorry for the delayed answer. I do confirm that the watermark still get printed when the field is disabled with a value in it. It is like if the code detect that the value is null when the field is disabled and print the watermark on top of what is present in the field. Any idea how to correct this?

  • Thanks for your proposal. It does the job but I see a side effect which is when a field is disabled the watermark is still visible on the top of the existing value. Have you got any idea how to fix this?

  • Hello, sorry for the delayed answer. I do confirm that the watermark still get printed when the field is disabled with a value in it. It is like if the code detect that the value is null when the field is disabled and print the watermark on top of what is present in the field. Any idea how to correct this?

  • Hello, sorry for the delayed answer. I do confirm that the watermark still get printed when the field is disabled with a value in it. It is like if the code detect that the value is null when the field is disabled and print the watermark on top of what is present in the field. Any idea how to correct this?

  • Thanks for your proposal. It does the job but I see a side effect which is when a field is disabled the watermark is still visible on the top of the existing value. Have you got any idea how to fix this?
