ASPxPivotGrid.DataSource Property
Gets or sets the object from which the data-bound control retrieves its list of data items.
Namespace: DevExpress.Web.ASPxPivotGrid
Assembly: DevExpress.Web.ASPxPivotGrid.v22.2.dll
NuGet Package: DevExpress.Web
Declaration
[DefaultValue(null)]
[PivotAPIMemberCategory(APICategory.RelationalSource)]
public override object DataSource { get; set; }Property Value
| Type | Default | Description |
|---|---|---|
| Object | null | An object that represents the data source from which the data-bound control retrieves its data. |
Remarks
Assigning a new value to the DataSource property causes a pivot grid update.
Note
The ASPxPivotGrid is also updated when the data source implementing the IBindingList interface raises the ListChanged event of the PropertyDescriptorAdded, PropertyDescriptorDeleted, PropertyDescriptorChanged or Reset type.
If some of the data source field values are custom objects (not numeric or string values), use the PivotGridOptionsData.CustomObjectConverter property to specify a serializer to be used to process them.
Note
The DataSource property cannot be set by themes or style sheet themes.
Example
This example demonstrates how to create an ASPxPivotGrid and bind it to data in code.
In this example, the ASPxPivotGrid and System.Web.UI.WebControls.AccessDataSource instances are created and initialized in code. Assign the AccessDataSource instance to the ASPxPivotGrid.DataSource property to bind the Pivot Grid to the created data source. Then call the ASPxPivotGrid.RetrieveFields method to generate DataSourceColumnBinding objects for each Pivot Grid field.
