DataTrigger not working

[Kevin Marois]

I'm trying to implement show/hide password textboxes. There is a PasswordBox and a TextBox both in the same grid cell, and a checkbox off to the right. When I check it, nothing happens. I get no binding errors. Anyone see what's wrong?

        <Style.Triggers>
                            <DataTrigger Binding="{Binding ElementName=chkShowPassword, Path=IsChecked}" Value="False">
                                <Setter Property="Visibility" Value="Hidden"/>
                            </DataTrigger>
                        </Style.Triggers>
                    
                
                
            

            <Style.Triggers>
                            <DataTrigger Binding="{Binding ElementName=chkShowPassword, Path=IsCheckd}"  Value="True">
                                <Setter Property="Visibility" Value="Visible"/>
                            </DataTrigger>
                        </Style.Triggers>

You don't have anything that submits the username and password. There is no "login" button. But, figuring out if the credentials are correct is not done in the XAML. It's done in the class your XAML is bound to, which you also didn't show. Sorry, I completely misread the question.

The Visibility property set directly on the control overrides the value set by the style. You also have the trigger on the password box the wrong way round - you want to hide it when the checkbox is checked, not unchecked. And you have a typo in the binding for the textbox - IsCheckd instead of IsChecked. Change your code to:

<PasswordBox
Grid.Row="0"
Grid.Column="0"
TabIndex="2"
cls:PasswordBoxAssistant.BindPassword="True"
cls:PasswordBoxAssistant.BoundPassword="{Binding Password, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
Width="400"

<PasswordBox.Style>
    <Style TargetType="PasswordBox">
        <Setter Property="Visibility" Value="Visible" />
        <Style.Triggers>
            <DataTrigger Binding="{Binding ElementName=chkShowPassword, Path=IsChecked}" Value="True">
                <Setter Property="Visibility" Value="Hidden"/>
            </DataTrigger>
        </Style.Triggers>
    </Style>
</PasswordBox.Style>

</PasswordBox>

<TextBox
Grid.Row="0"
Grid.Column="0"
Text="{Binding Password, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
TabIndex="2"
Width="400"

<TextBox.Style>
    <Style TargetType="TextBox" BasedOn="{StaticResource textBoxStyle}">
        <Setter Property="Visibility" Value="Hidden" />
        <Style.Triggers>
            <DataTrigger Binding="{Binding ElementName=chkShowPassword, Path=IsChecked}"  Value="True">
                <Setter Property="Visibility" Value="Visible"/>
            </DataTrigger>
        </Style.Triggers>
    </Style>
</TextBox.Style>

</TextBox>

That did it. Thank you

If it's not broken, fix it until it is. Everything makes sense in someone's mind. Ya can't fix stupid.
