Methods

AlterControlInfo(ControlDisplayInfo)

Used to alter the sql wrapper control to hold a selection of all sql wrappers, and the entity control to have a selection of all entities

Declaration
protected override void AlterControlInfo(ControlDisplayInfo info)
Parameters
Type Name Description
ControlDisplayInfo info

The description for a control being displayed by this parameter view
Overrides
LemonEdge.Client.Core.Support.ParamSingleViewerController<LemonEdge.API.Tasks.Parameters.ExportCSVParameter>.AlterControlInfo(LemonEdge.Client.Core.Views.Core.ControlDisplayInfo)

ControlNames()

The controls to display for the parameter are a ISQLWrapper selection and an entity type selection, indicating the data to export comes from an underlying sql wrapper or raw entity record data

Declaration
protected override IEnumerable<ControlDisplayInfoLight> ControlNames()
Returns
Type Description
System.Collections.Generic.IEnumerable<ControlDisplayInfoLight>

A ISQLWrapper selection and an entity type selection control
Overrides
LemonEdge.Client.Core.Support.ParamSingleViewerController<LemonEdge.API.Tasks.Parameters.ExportCSVParameter>.ControlNames()

GetExportableColumnInfo(SQLWrapperInterpretor, IEnumerable<ColumnDescriptor>)

Returns a list of columns that can be exported from the specified sql wrapper taking into account the currently visibleColumns in the grid displaying sql wrapper results

Declaration
public static IEnumerable<ControlDisplayVisibilityInfo> GetExportableColumnInfo(SQLWrapperInterpretor helper, IEnumerable<ColumnDescriptor> visibleColumns)
Parameters
Type Name Description
SQLWrapperInterpretor helper

A sql wraper that holds the structure of all the columns returned from executing it
System.Collections.Generic.IEnumerable<ColumnDescriptor> visibleColumns

A list of currently visible columns for the sql wrapper that is displaying a result set. Used to ensure the resulting list of columns is correctly marking those that are visible or not according to their current setup
Returns
Type Description
System.Collections.Generic.IEnumerable<ControlDisplayVisibilityInfo>

A list of columns that can be exported from the specified sql wrapper taking into account the currently visibleColumns in the grid displaying sql wrapper results

GetQueryParameters<T>(T, String, Boolean, Boolean, ModelViewController, IEntityUpdater, Func<Task<ISQLWrapper>>, IBaseEntity, Boolean, IModelLayoutCommon)

Returns a ExportCSVParameter with the parameters, filters, and settings required to execute the export of data the way the user requires through popup param windows if required

This function may popup parameter windows for the parameter selections, any visible column selection and possible further filtering depending on the provided settings and requirement

Declaration
public static Task<T> GetQueryParameters<T>(T param, string entityTypeKey, bool allowColumnFilter, bool ignoreCollectionExportableInterfaceOfController, ModelViewController controller, IEntityUpdater cn, Func<Task<ISQLWrapper>> getWrapper, IBaseEntity contextItem, bool allowDesign, IModelLayoutCommon host)
    where T : class, IQueryExportParams
Parameters
Type Name Description
T param

The initial setting describing at least which type of data should be exported, including any other configured parameters
System.String entityTypeKey
System.Boolean allowColumnFilter
System.Boolean ignoreCollectionExportableInterfaceOfController

Indicates if the controller should be ignored for using it as a source of the data to export
ModelViewController controller

The controller this data can be exported from - can be null if all the data is explicitly defined in the param
IEntityUpdater cn

An updater context for evaluating formulas when getting default parameter values
System.Func<System.Threading.Tasks.Task<ISQLWrapper>> getWrapper

A function that returns the sql wrapper used by the param if configured to use a sql wrapper
IBaseEntity contextItem
System.Boolean allowDesign
IModelLayoutCommon host

The host context the popups (if they occur) should operate within
Returns
Type Description
System.Threading.Tasks.Task<T>

A ExportCSVParameter with the parameters, filters, and settings required to execute the export of data the way the user requires through popup param windows if required
Type Parameters
Name Description
T

GetSerializedParameters(SQLWrapperResultsViewParams, SQLWrapperInterpretor, IEntityUpdater, Object, IModelLayoutCommon, Boolean, Boolean)

Returns a serialized dictionary of parameter name and value, selected by the user from a popup presented for all posssible parameters

Declaration
public static Task<(bool Valid, bool Accepted, string SerializedParams, SQLWrapperResultsViewParams Params)> GetSerializedParameters(SQLWrapperResultsViewParams p, SQLWrapperInterpretor helper, IEntityUpdater updater, object contextItem, IModelLayoutCommon host, bool run, bool forceParamShow)
Parameters
Type Name Description
SQLWrapperResultsViewParams p

The current parameters to display to the user and allow selection of. Could display pivot, chart, or sql wrapper parameters for executing the underlying sql wrapper.
SQLWrapperInterpretor helper

The underlying sql wrapper to display parameters for
IEntityUpdater updater

The updater context for running custom formulas with for default parameter values
System.Object contextItem

The context item that formulas can be run against
IModelLayoutCommon host

The owning host context this runs within
System.Boolean run

Indicates these parameter values will be executed. If true then return false if the current p is not valid.

If false will prompt user for parameters via a popup window for the appropriate SQLWrapperResultsViewParams type (sqlwrapper, pivot, chart, etc)

System.Boolean forceParamShow

Forces the parameters to be shown even if the required parameters already have a value
Returns
Type Description
System.Threading.Tasks.Task<System.ValueTuple<System.Boolean, System.Boolean, System.String, SQLWrapperResultsViewParams>>

The following tuple:

  • Valid: Indicates the returned SerializedParam is valid for the required parameters
  • Accepted: Indicates the user accepted the parameters and did not cancel out of any popup parameters
  • SerializedParams: A serialized dictionary of parameters and their values to use
  • Params: The changed SQLWrapperResultViewParams parameters

GetVisibleColumns(Boolean, ModelViewController, SQLWrapperInterpretor, EntityDescriptor)

Returns a list of columns that can be exported from the specified dataset

The columns used come from an ICollectionExportable controller if the ignoreCollectionExportableInterfaceOfController is false.

Else they come from the definition of the provided sqlWrapperHelper, or the properties of the provided entity descriptor desc
Declaration
public static Task<IEnumerable<ControlDisplayVisibilityInfo>> GetVisibleColumns(bool ignoreCollectionExportableInterfaceOfController, ModelViewController controller, SQLWrapperInterpretor sqlWrapperHelper, EntityDescriptor desc)
Parameters
Type Name Description
System.Boolean ignoreCollectionExportableInterfaceOfController

If false and controller is of type ICollectionExportable then the controller is used to return the visible columns for exporting
ModelViewController controller

If ignoreCollectionExportableInterfaceOfController is false and this controller is of type ICollectionExportable then it is used to return the visible columns for exporting
SQLWrapperInterpretor sqlWrapperHelper

Uses the visible columns definied within the structure of the provided sql wrapper
EntityDescriptor desc

Uses the properties of the provided entity descriptor
Returns
Type Description
System.Threading.Tasks.Task<System.Collections.Generic.IEnumerable<ControlDisplayVisibilityInfo>>

A list of columns that can be exported from the specified dataset. Must come from the controller defintion, a sql wrapper helper, or an entity descriptor

InitCommands(IList<ViewCommand>)

Adds the query parameters command which provides additional parameters for executing a sql wrapper, or filtering a sql wrapper/entity type

Declaration

Parameters
Type Name Description
System.Collections.Generic.IList<ViewCommand> commands

The current list of controls for this parameter controller
Overrides

OnItemChanged(Object, PropertyChangedEventArgs)

Occurs whenever a change in the ExportCSVParameter properties being displayed is detected

Used to update the commands for this parameter, and to ensure labels are correctly updated on item selections

Declaration
protected override void OnItemChanged(object sender, PropertyChangedEventArgs e)
Parameters
Type Name Description
System.Object sender

The object raising the property changed
System.ComponentModel.PropertyChangedEventArgs e

The property that has been changed
