This overview introduces globalization and localization in Windows Presentation Foundation (WPF). Globalization is the design and development of applications that perform in multiple locations. For example, globalization supports localized user interfaces and regional data for users in different cultures. I would like to see if I can create a list of ExpandoObjects, bind them to XamDataGrid, and achieve the same effect like that of DataTable, with fewer lines of code. I could use the standard WPF DataGrid as listed above and it works. I'm using XamDataGrid across my application and I don't want to use the WPF. May 26, 2009 Dictionary where the Key of the KeyValuePair is the DataGrid Column Header and the Value of the KeyValuePair is the data for that column and each List item is a datagrid record? Or some other type of collection? DataTemplate is about the presentation of data and is one of the many features provided by the WPF styling and templating model. For an introduction of the WPF styling and templating model, such as how to use a Style to set properties on controls, see the Styling and Templating topic.

AutoGenerateColumns property automatically generate columns for display in UI from the bounded data source.
It takes every public property in bounded data source to generate columns. For example, if you bind to below Employee class to DataGrid:
Only one column is generated for Property4 in the DataGrid because it has public modifier. Rest all properties and variables are ignored.
Set DataGrid AutoGenerateColumns Property
You can set AutoGenerateColumns property in DataGrid both in XAML and code-behind class.
Type of Generated Columns
By default DataGrid based on the column type generate columns. For example, if you bind to a bool property, then it will generate a checkbox column.
Below is table of data type mapping:
Data Type | Column Generated |
---|---|
bool | Checkbox column |
enum | Combobox column |
Uri | Hyperlink column |
string | Textbox column |
DateTime | Textbox column |
int | Textbox column |
double | Textbox column |
decimal | Textbox column |
AutoGenerateColumn Example
Below is full example of DataGrid auto generation of columns:
In the above code, we have create a new DataGrid name 'myDataGrid' and set AutoGenerateColumns property to True.
In the code-behind class, we have create a class 'Employee' which has properties of different types like int, string, bool, enum, Uri, DateTime. Then we have created an ObservableCollection of Employee class and create three sample employee type and bind ObservableCollection to DataGrid in the ItemsSource property.
Events

- AutoGeneratedColumns
AutoGeneratingColumn event

This event provides DataGridAutoGeneratingColumnEventArgs event argument which contains three important properties:
- Cancel - For cancel the column to be generated
- Column - Generated column
- PropertyName - Get the name of property bound to generated column
You can use this event for two important tasks:
- Remove the column from the being created
- Change/Update the header of generated column
Below is the example of both:
In the above code, I have checked the PropertyName of event argument. If PropertyName is 'ID' then set e.Cancel to true. Then ID column will not be generated.
I have also changed the header of Name column by changed the Header property of Column property of event argument.
AutoGeneratedColumns event
This event occurs when the auto completion process is completed by the DataGrid.
