Accessing App.Config Properties From XAML

Problem:

How to access user settings stored in app.config file from XAML?

Solution:

First we need to add reference to Properties in our XAML file.

xmlns:p="clr-namespace:MyExample.Properties"

And this is how we use it:

<TextBox Name="serverNameTextBox" 
         Grid.Column="1" Grid.Row="0"
         Text="{Binding Source={x:Static p:Settings.Default}, 
                                Path=ServerName, Mode=OneWay}">
</TextBox>

Hope it will save your time.

WPF DateTimePicker In DataGrid

Problem:

Need to integrate DateTimePicker control into datagrid cell.

Solution:

For some business applications regular WPF DatePicker is not enough, sometimes you need also time and seconds.
I was quite surprised when figured out that .NET Framework 4.0 does not have such control as DateTimePicker.
Well, fortunately there is such a thing called Extended WPF Toolkit.
All you need is download it and to add reference to WPFToolkit.Extended.dll in your WPF project.
Here is how you use DateTimePicker with DataGrid:

WPF Datagrid Edit Row Toggle Button

Problem:

I have a WPF datagrid with some data, some of the fields are configurable.

User can edit only one row at the same time.

Solution:

Edit Mode locked for all rows

Edit Mode unlocked for second row
