PivotGridFieldBase.DataBinding Property

Gets or sets an object that specifies the Pivot Grid field’s source data.

Namespace: DevExpress.XtraPivotGrid

Assembly: DevExpress.PivotGrid.v22.1.Core.dll

Declaration

[DefaultValue(null)]
public DataBindingBase DataBinding { get; set; }

Property Value

Type Default Description
DataBindingBase null

A DataBindingBase descendant that specifies the source data and calculation type.

Remarks

Pivot Grid uses the Binding API to bind Pivot Grid fields to data. A data binding source can be a column in the data source or a calculated expression.

The following types of bindings are available:

Column Binding
Allows you to bind a Pivot Grid field to a data column in the data source. The Pivot Grid field obtains its values from a field in the data source.
Expression Binding
Allows you to bind a Pivot Grid field to an expression and display the calculated result. The expression can be a formula or an aggregate function.
Calculation Binding
Allows you to bind a Pivot Grid field to a window calculation and display aggregated values in the window.

Each specified binding object is a DataBindingBase descendant. This object is assigned to the Pivot Grid field’s DataBinding property.

Refer to the following topic for more information about binding concepts and usage examples: Data Binding API.

The following table illustrates Pivot Grid data processing modes that support the Binding API:

Legacy and Legacy Optimized Optimized Server mode OLAP
Column Binding no yes yes yes
Expression Binding no yes yes yes
Calculation Binding no yes no no

Refer to the following article for more information about data processing modes: Pivot Grid Data Processing Modes.

Example

The following example shows how to use the expression binding to bind the FirstValue([ProductName]) expression to the First Product Sold field. The expression returns the first product sold by Sales Persons in each product category:

First Value Custom Function Example

using DevExpress.XtraPivotGrid;
using System.Windows.Forms;

namespace WinPivot_CustomFunctions {
    public partial class Form1 : Form {
        public Form1() {
            InitializeComponent();     
            //  ...
            PivotGridField pivotGridField1 = new PivotGridField() {
                Area = PivotArea.DataArea,
                AreaIndex = 0,
                Caption = "First Product Sold",
                FieldName = "FirstProductSold"
            };
            pivotGridControl1.Fields.Add(pivotGridField1);
            pivotGridField1.DataBinding = new ExpressionDataBinding() { 
                Expression = "FirstValue([ProductName])" };
                //  ...
        }      
    }
}
