AllowCopyCommand

Indicates that by default selected entities can be copied by the user with the copy command

Declaration

public override bool AllowCopyCommand { get; }

Overrides

LemonEdge.Client.Core.Views.Core.BaseGridController<LemonEdge.API.Entities.Design.ICustomValidation>.AllowCopyCommand

AllowXMLImportExport

Indicates the command to allow the xml export of the data by the user is included in the InitCommands(IList<ViewCommand>)

The default is true if the type ICustomValidation derives from ISetCopier

Declaration

public override bool AllowXMLImportExport { get; }

Property Value

Type	Description
bool

Overrides

LemonEdge.Client.Core.Views.Core.BaseGridControllerAny<LemonEdge.API.Entities.Design.ICustomValidation>.AllowXMLImportExport

AutoOpenNewItemInTab

Indicates when creating a new item in the grid that it should automatically be opened in a new tab as well

The default is true if the type ICustomValidation is an entity that is not a IsStandingDataEntity

Declaration

public override bool AutoOpenNewItemInTab { get; }

Property Value

Type	Description
bool

Overrides

LemonEdge.Client.Core.Views.Core.BaseGridControllerAny<LemonEdge.API.Entities.Design.ICustomValidation>.AutoOpenNewItemInTab

CheckIsLockedForCanWrite

Indicates the controller should check if the item is locked before allowing CanWrite to be true. Defaults to true.

Declaration

protected override bool CheckIsLockedForCanWrite { get; }

Property Value

Type	Description
bool

Overrides

ModelViewController.CheckIsLockedForCanWrite

CollectionRelationshipColumnName

This is the property on the ICustomValidation entities that holds a relationship value that points to the SingleItem type

This controller will automatically use that to filter the correct entities for the grid in AlterQuery(QueryableExecuter<TCollection>)

Declaration

public override string CollectionRelationshipColumnName { get; }

Property Value

Type	Description
string

Overrides

LemonEdge.Client.Core.Views.Core.BaseGridRelatedCollectionController<LemonEdge.API.Entities.Data.IFolder, LemonEdge.API.Entities.Design.ICustomValidation>.CollectionRelationshipColumnName

DisplayIfNull

Indicates that even if the item is null the view should still update and display a null value. Default value is false.

Declaration

public override bool DisplayIfNull { get; }

Property Value

Type	Description
bool

Overrides

ModelViewController.DisplayIfNull

ViewAllFolders

Declaration

public bool ViewAllFolders { get; set; }

Property Value

Type	Description
bool

Methods

AlterColumnInfo(ControlDisplayInfo)

Provides an inheriting controller the opportunity to alter the specified column before it is added to the IBaseGrid<T>

This is used in conjunction with columns defined via ColumnNames(), rather than Columns() which explicitly defines all information

The default operation provides a CustomComboItems if the column is against a property that is a link to an entity type (IsEntityLink)

Declaration

protected override void AlterColumnInfo(ControlDisplayInfo info)

Parameters

Type	Name	Description
ControlDisplayInfo	info	The definition of the column that can be updated before being created in the IBaseGrid<T>

Overrides

LemonEdge.Client.Core.Views.Core.BaseGridControllerAny<LemonEdge.API.Entities.Design.ICustomValidation>.AlterColumnInfo(LemonEdge.Client.UI.API.Controls.ControlDisplayInfo)

AlterQuery(QueryableExecuter<ICustomValidation>)

Additionally alters the base query alteration by ensuring all entities returned are related to the SingleItem by having their CollectionRelationshipColumnName have the same value as the SingleItem ID

This is achieved via AddRelationshipJoin(QueryableExecuter<TCollection>) which can be overidden to customise how the entities of type ICustomValidation are precisely related to the SingleItem if not directly through that join

Declaration

protected override QueryableExecuter<ICustomValidation> AlterQuery(QueryableExecuter<ICustomValidation> query)

Parameters

Type	Name	Description
QueryableExecuter<ICustomValidation>	query	The existing query to return all the results that will populate the grid

Returns

Type	Description
QueryableExecuter<ICustomValidation>	An altered query that also ensures all entities returned are related to the SingleItem by having their CollectionRelationshipColumnName have the same value as the SingleItem ID

Overrides

LemonEdge.Client.Core.Views.Core.BaseGridRelatedCollectionController<LemonEdge.API.Entities.Data.IFolder, LemonEdge.API.Entities.Design.ICustomValidation>.AlterQuery(LemonEdge.Utils.QueryableExecuter<LemonEdge.API.Entities.Design.ICustomValidation>)

ColumnNames()

A list of all the columns to be dynamically created in the IBaseGrid<T>

This is used by the system to create the actual ControlDisplayInfo classes required from the Columns() property

You can override this to provide a simple definition of each column (combined with AlterControlInfo(ControlDisplayInfo) for more detail), or you can just override Columns() and ignore this

Declaration

protected override IEnumerable<ControlDisplayInfoLight> ColumnNames()

Returns

Type	Description
IEnumerable<ControlDisplayInfoLight>	A list of all the columns to be dynamically created in the IBaseGrid<T>

Overrides

LemonEdge.Client.Core.Views.Core.BaseGridControllerAny<LemonEdge.API.Entities.Design.ICustomValidation>.ColumnNames()

DisplayUI()

Initializes the grid, and creates every ControlDisplayInfo in the defined Columns() and creates them on the grid

Then loads the data for the grid accounting for all view sorting, filtering, searching and paging, and loads the results into the grid as an observable collection

Declaration

public override Task DisplayUI()

Returns

Type	Description
Task	A task indicating the completion of the operation

Overrides

LemonEdge.Client.Core.Views.Core.BaseGridControllerAny<LemonEdge.API.Entities.Design.ICustomValidation>.DisplayUI()

GetCanWrite(object)

Declaration

protected override Task<bool> GetCanWrite(object item)

Parameters

Type	Name	Description
object	item

Returns

Type	Description
Task<bool>

Overrides

ModelViewController.GetCanWrite(object)

InitCommands(IList<ViewCommand>)

Adds the following commands, if the associated AllowXXXCommand property returns true: A public toggle, multi-select row, open, column visiblitiy, transfer visible, search, view cancelled, view system, export, new, copy, move up/down, xml export, and delete commands

Declaration

protected override void InitCommands(IList<ViewCommand> commands)

Parameters

Type	Name	Description
IList<ViewCommand>	commands	The initial set of commands for this view

Overrides

UpdateNewItem(ICustomValidation)

Updates any new item created in this grid to also have the CollectionRelationshipColumnName property hold the value of the SingleItem ID

Declaration

protected override Task UpdateNewItem(ICustomValidation item)

Parameters

Type	Name	Description
ICustomValidation	item	The new item created for this grid

Returns

Type	Description
Task	A task indicating the completion of the operation

Overrides

LemonEdge.Client.Core.Views.Core.BaseGridRelatedCollectionController<LemonEdge.API.Entities.Data.IFolder, LemonEdge.API.Entities.Design.ICustomValidation>.UpdateNewItem(LemonEdge.API.Entities.Design.ICustomValidation)
