FieldLayout Class

Used in a DataPresenterBase to define the layout of Fields for one or more items.
Public Class FieldLayout 
   Inherits Infragistics.DependencyObjectNotifier
public class FieldLayout : Infragistics.DependencyObjectNotifier 

DataRecords are created lazily as each item in the DataSource is requested. When a DataRecord is created DataPresenterBase's DataPresenterBase.FieldLayouts collection is searched for an existing FieldLayout whose Fields match the DataItem's properties. If one is not found then a new FieldLayout is created, in which case the FieldLayoutInitializing and FieldLayoutInitialized events will be raised.

Note: If the new FieldLayout's AutoGenerateFieldsResolved property returns true then the Fields collection is automatically populated with a Field for every public property on the data item. This is done between the FieldLayoutInitializing and FieldLayoutInitialized events.

In any case the AssigningFieldLayoutToItem event is raised to allow a different FieldLayout to be assigned to the DataRecord. Finally the InitializeRecord event is raised.

Refer to the Fields topic in the Developer's Guide for an explanation of fields.

Refer to the Theory of Operation topic in the Developer's Guide for an explanation of how this object is used.

The following example demonstrates how to create a FieldLayout and add it to the FieldLayouts property of a DataPresenterBase derived control. It also demonstrates how to create and initialize the FieldSettings of a FieldLayout and create the Fields that will make up that FieldLayout including the use of UnboundField instances.
<igDP:XamDataGrid x:Name="XamDataGrid12" BindToSampleData="true">
<!-- define a field layout that will match the data -->

<!-- initialize settings for the fields in this specific field layout -->
<igDP:FieldSettings CellClickAction="SelectRecord"/>

<!-- define the fields for the field layout -->
<igDP:Field Name="name" Label="Name"/>
<igDP:Field Name="department" Label="Dept." />
<igDP:Field Name="salary" Label="Salary"/>
<igDP:Field Name="email" Label="Email"/>
                    The XamDataGrid allows you to include Unbound Fields in a
                    FieldLayout. This sample shows how you can use
                    Unbound Fields to include calculated values. 
<igDP:UnboundField Name="SubTotal" Label="Sub-total"></igDP:UnboundField>
<igDP:UnboundField Name="SalesTax" Label="Sales Tax (7%)" />
<igDP:UnboundField Name="Total" Label="Total" DataType="{x:Type sys:Decimal}"></igDP:UnboundField>
