Trying to bind column headers to properties in my C# code - xaml

Question

I currently have:
<Window x:Class="Client_SCM.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:Client_SCM"
mc:Ignorable="d"
Title="Swords Call Monitor 2.0" Height="350" Width="474">
<Grid HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Margin="5"
ShowGridLines="True">
<DataGrid x:Name="dataGrid"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Margin="5"
AlternatingRowBackground="Aqua" Loaded="dataGrid_Loaded" AutoGenerateColumns="False"/>
</Grid>
And I'm trying to implement something like this into it:
<DataGridTextColumn Binding="{Binding WhateverIWantToDisplay}" >
<Setter Property="Background" Value="Green" />
<Style.Triggers>
<DataTrigger Binding="{Binding Foo}" Value="1">
<Setter Property="Background" Value="Blue" />
</DataTrigger>
<DataTrigger Binding="{Binding Foo}" Value="2">
<Setter Property="Background" Value="Red" />
</DataTrigger>
<DataTrigger Binding="{Binding Foo}" Value="2">
<Setter Property="Background" Value="Yellow" />
</DataTrigger>
</Style.Triggers>
</Style>
The error I'm getting is "The property 'Content' can only be set once".
Any help would be appreciated!

Try using Header instead of Binding on your DataGridTextColumn.
<Window x:Class="Client_SCM.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:Client_SCM"
mc:Ignorable="d"
Title="Swords Call Monitor 2.0" Height="350" Width="474">
<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5" ShowGridLines="True">
<DataGrid x:Name="dataGrid" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5"
AlternatingRowBackground="Aqua" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="{Binding WhateverIWantToDisplay}">
</DataGridTextColumn>
</DataGrid.Columns>
</DataGrid>
</Grid>
</Window>
