code snippet Formula1Demo/GridUC.xaml.cs
Figure 36-15 shows the running application
with the default grid styles and headers.
In the next DataGrid example, the grid is
customized with custom columns and grouping.
Custom Columns
Setting the property AutoGenerateColumns
of the DataGrid to False doesn’t generate
default columns. You can create custom
columns with the Columns property. You
can also specify elements that derive from
DataGridColumn. Predefined classes exist
that can be used. DataGridTextColumn
can be used to read and edit text.
DataGridHyperlinkColumn is for displaying
hyperlinks. DataGridCheckBoxColumn
figure 36-15
displays a check box for Boolean data. For
a list of items in a column you can use the
DataGridComboBoxColumn. More DataGridColumn types will be available in the future, but if you need a
different representation now, you can use the DataGridTemplateColumn to define and bind any elements
you want.
The example code uses DataGridTextColumn elements that are bound to the Position and Racer
properties. The Header property is set to a string for display. Of course you can also use a template to define
a complete custom header for the column:
