Change foreground of a textbox embedded in a CellTemplate


Change foreground of a textbox embedded in a CellTemplate

To fix this issue Your style has triggers for the TextBox that it is applied to. A TextBox doesn't know if the containing ListViewItem is selected or not, so this won't work.
To get the connection to the containing ListViewItem, you can use a DataTrigger instead, let a RelativeSource expression travel up the visual tree until it finds the ListViewItem and bind to its IsSelected property:
code :
<Style TargetType="{x:Type TextBox}">
    <Setter Property="Foreground" Value="Green" />
    <Style.Triggers>
        <DataTrigger
            Binding="{Binding RelativeSource={RelativeSource AncestorType={x:Type ListViewItem}}, Path=IsSelected}"
            Value="True">
            <Setter Property="Foreground"
                    Value="Black" />
        </DataTrigger>
    </Style.Triggers>
</Style>

To fix this issue Apparently you cannot change the background of textbox when it gets focused, not in dark theme (It's even like that in the integrated textboxes of the system).
So I came up with a solution that solved my problem,

will help you You can change the Style of your TextBox for the disabled state. To achieve this more easily, you can open your .xaml document in Expression Blend, Right Click in your TextBox -> Edit Template... -> Edit a Copy.
Then you choose the name you want for your Style. After that search for the States Tab, and click it. After that choose the disabled state. Then you can edit the TextBox to be whatever you like for the disabled state.

I think the issue was by ths following , Much Simpler Way
Define a Style with TargetType set to Textbox and with no Key. This way this style will be applied to all textbox in the application without the need to bind the style or the foreground for each textbox.
code :
<Application.Resources>
    <SolidColorBrush  Color="Red" x:Key="txtColor" />

    <Style TargetType="TextBox">
        <Setter Property="Foreground" Value="{DynamicResource txtColor}" />
    </Style>
</Application.Resources>
private void Button_Click(object sender, RoutedEventArgs e)
{
    if (Application.Current.Resources.Contains("txtColor"))
    {
         Application.Current.Resources["txtColor"] = new SolidColorBrush(Colors.Blue);
    }
}

this will help I have a TextBox style. I am trying to make a Placeholder(I realized I am not the first to ask about this.) However I found a very uncomplicated way that works for my needs. Once the user clicks in the box the "email" is removed. , This should be what you are looking for:
code :
<Trigger Property="IsKeyboardFocused" Value="True">
            <Setter Property="Foreground" Value="Black"/>
            <Setter Property="FontWeight" Value="Medium"/>
</Trigger>

Hope that helps How can I change foreground of TextBox if text is changed? For example, I will write "zzz" and foreground will be change on "Red". , First you need to add Foreground and TextChanged to TextBox:
code :
<TextBox Foreground="{DynamicResource txtColor}" Width="200" Text="asdasd" x:Name="qwerty" TextChanged="TextBox1_TextChanged">

</TextBox>
private void TextBox1_TextChanged(object sender, TextChangedEventArgs e)
{
    TextBox textBox = sender as TextBox;
    if(textBox.Text == "zzz")
    {
        Application.Current.Resources["txtColor"] = new SolidColorBrush(Colors.Red);
    }
}
