Syntax

public class ControlDisplayInfo : ControlDisplayVisibilityInfo, IEquatable<ControlDisplayInfo>

Constructors

ControlDisplayInfo(short, ColumnDescriptor, bool, double?)

Creates a new control display info to define the control that should be created in the client application ui with the specified properties

Declaration

public ControlDisplayInfo(short index, ColumnDescriptor colDesc, bool editable, double? width)

Parameters

Type	Name	Description
short	index	The order this control should appear in the ui view it is created in
ColumnDescriptor	colDesc	The definition of the property on the object this control is displaying and interacting with
bool	editable	Indicates if the control is editable by the user
double?	width	The width to display this control at in compliant client UIs. A null value defaults to the standard default width for that control type

ControlDisplayInfo(short, Type, string, string, string, double?)

Creates a new control display info that is not bound to a property against the object, and instead evaluates a formula dynamically at runtime and displays the resulting value

This is only compatible with the LemonEdge.Client.Core.Views.Core.IBaseDefaultSingleView<T>, not the grid, or any other view just now.

Declaration

public ControlDisplayInfo(short index, Type propertyType, string formulaValue, string userFriendlyName, string description = null, double? width = null)

Parameters

Type	Name	Description
short	index	The order this control should appear in the ui view it is created in
Type	propertyType	The type of the value returned from the formula

string	description	An optional description for the control
double?	width	An optional width
