PivotGridField(String, FieldArea) Constructor
Initializes a new instance of the PivotGridField class with the specified field name and location.
Namespace: DevExpress.Xpf.PivotGrid
Assembly: DevExpress.Xpf.PivotGrid.v24.2.dll
NuGet Package: DevExpress.Wpf.PivotGrid
Declaration
Parameters
Name | Type | Description |
---|---|---|
fieldName | String | A String identifying the name of the database field. This value is assigned to the PivotGridField.FieldName property. |
area | FieldArea | A FieldArea enumeration value that defines the location for the PivotGridField object within the control. This value is assigned to the PivotGridField.Area property. |
Remarks
This constructor initializes the PivotGridField.FieldName and PivotGridField.Area properties with the specified values. All the other properties of the created PivotGridField object are set to default values.
Example
The following example demonstrates how to bind the PivotGridControl to a “SalesPerson” view in the nwind.mdb database, which ships with the installation.
Follow the steps below to connect the Pivot Grid to a database.
- Create an OleDbConnection object and specify the connection string in its constructor.
- Create an
OleDbDataAdapter
instance to select records from the data source. - Create a new
DataSet
object and populate it with data. - Use the PivotGridControl.DataSource property to assign the resulting data source to the Pivot Grid.
Follow the steps below to create and configure Pivot Grid fields.
- Create a PivotGridField object and add it to the PivotGridControl.Fields collection.
- Specify the field’s area and position within this area. For this, use the PivotGridFieldBase.Area and PivotGridField.AreaIndex properties.
AreaIndex
can be set only after the field is added to the control’s field collection. - Create a DataSourceColumnBinding object for each field.
- Set the DataSourceColumnBinding.ColumnName property to the name of the column in the data source. The Pivot Grid fields obtain their values from columns in the data source.
- Assign the
DataSourceColumnBinding
object to the field’s PivotGridField.DataBinding property.
