A Brief Introduction to FluentDataGrid
One of the great features of data controls like DataGrid in WPF is the ability to style cells based on their values. This feature can significantly enhance the presentation of data in a more meaningful and visually appealing way. Here, we will show you different ways to achieve this and how to implement them.
Using DataTriggers
One of the common methods for styling based on values in WPF is using DataTriggers. DataTriggers allow you to apply styles based on specific data values.
Implementation Steps
To begin, you need to define your DataTemplate and then use DataTrigger within it. This allows you to dynamically style each cell based on specific value or condition.
Example of Implementing DataTriggers
Let’s look at a simple example of how we can style a DataGrid's cells based on their values using DataTriggers.
<DataGrid x:Name="myDataGrid" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="Value" Binding="{Binding Value}">
<DataGridTextColumn.CellStyle>
<Style TargetType="DataGridCell">
<Style.Triggers>
<DataTrigger Binding="{Binding Value}" Value="High">
<Setter Property="Background" Value="Red" />
</DataTrigger>
<DataTrigger Binding="{Binding Value}" Value="Medium">
<Setter Property="Background" Value="Yellow" />
</DataTrigger>
<DataTrigger Binding="{Binding Value}" Value="Low">
<Setter Property="Background" Value="Green" />
</DataTrigger>
</Style.Triggers>
</Style>
</DataGridTextColumn.CellStyle>
</DataGridTextColumn>
</DataGrid.Columns>
</DataGrid>
Line by Line Explanation of the Code
<DataGrid x:Name="myDataGrid" AutoGenerateColumns="False">This line defines a DataGrid and does not automatically create columns based on data.
<DataGrid.Columns>This line specifies the custom columns included in the DataGrid.
<DataGridTextColumn Header="Value" Binding="{Binding Value}">Here, we define a text column whose data is fetched using Binding.
<DataGridTextColumn.CellStyle>This line provides the ability to apply separate styles to the cells of this column.
<Style TargetType="DataGridCell">This line identifies the target element type for the style, which is DataGridCell in this case.
<Style.Triggers>This creates triggers that apply styles based on specific conditions.
<DataTrigger Binding="{Binding Value}" Value="High">A DataTrigger that checks if the cell's value is 'High'.
<Setter Property="Background" Value="Red" />If the value is 'High', this will set the cell's background color to red.
</DataTrigger>End of the DataTrigger.
