preventing greyed-out effect when TextBox.IsReadOnly = true

08-11-2009 8:24 AM |

I have textboxes which I want to be non-editable at certain times. However I don't want them to be greyed out when they are non-editable. Since converting the project to SL3 they are greyed out. Is this easy to change? If not I can just swap a TextBlock control with the same content for the contexts where they should not be editable.

Thanks

Easiest way would be to change the readonly style for the textbox.

Open your project in blend, right click on the textbox and select Edit Template -> Edit a Copy.

Thanks.

The textboxes are added programmatically, not defined in xaml. I don't seem to be able to reference the template in the code. I have the template defined in App.Xaml. Haven't used control templates before so It's probably something basic...

You can set the style of the textbox using the style property and by retreiving your new style from whatever resource you have stored it in.

Do a search on dynamic styles and you should get a few quick ideas on how to do this.

Thanks for your help.

I followed your suggestion and also referenced the resource dictionary in the app.xaml file.

I was able to reference the style and achieve the desired effect with a textbox defined in the xaml.

However the style was not applied to the textboxes when I tried applying programmaticlly in the way you described, although no error was given.

I used breakpoints to see that the template property and the style property of the programmatically-added textboxes were null. The template property and the style property of the textbox defined in xaml both had values.

So I just need to find how to apply the style/template programmatically.

It works now.

I changed 

Resources["MyTextBoxStyle"] as Style;

to

Application.Current.Resources["MyTextBoxStyle"] as Style;

Thanks again for your help!

 edit:"Mark as answer" does not seem to be working for me on this atm.

Will take note of the correct way to resolve the resource.

Sometimes mark as answer doesn't work because the link you follow for example has a # symbol in it which makes the mark as answer fail. Removing the # and everything to the right of it and hitting enter will allow it to work.

Let me some abuse style for TextBox only for text selection :)

in App.xaml

<Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

x:Class="iFlexBillAnalyser.App"

xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"

xmlns:System="clr-namespace:System;assembly=mscorlib"

>

<Application.Resources>

<ResourceDictionary>

<Style x:Key="Texted" TargetType="TextBox">

<Setter Property="IsReadOnly" Value="True" />

<Setter Property="BorderThickness" Value="0" />

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

<Style x:Key="OnlySelectedTextBox" TargetType="TextBox">

<Setter Property="IsReadOnly" Value="True"/>

<Setter Property="BorderThickness" Value="0"/>

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

<Setter Property="Foreground" Value="#FF000000"/>

<Setter Property="Padding" Value="2"/>

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

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="TextBox">

<Grid x:Name="RootElement">

<Border x:Name="Border" Opacity="1" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="1">

<ScrollViewer x:Name="ContentElement" BorderThickness="0" IsTabStop="False" Padding="{TemplateBinding Padding}"/>

</Border>

</Grid>

</ControlTemplate>

</Setter.Value>

</Setter>

</ResourceDictionary>

</Application>
