IPivot.BeginSelectionUpdate

Syntax

BeginSelectionUpdate;

Description

The BeginSelectionUpdate method disables selection in data source on changing selection in the table.

Comments

After calling this method and before calling the IPivot.EndSelectionUpdate method changing of a selection, available in the IPivot.Selection property, will not result in changing of a selection in original data source.

Example

Executing the example requires a form containing the following components:

Button named Button1.
TabSheetBox named TabSheetBox1.
UiErAnalyzer named UiErAnalyzer1 that is a data source for TabSheetBox1.

Add links to the Dimensions, Pivot system assemblies.

The example is a handler of the OnClick event for the Button component.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    OLAP: IEaxAnalyzer;
    Pivot: IPivot;
    DimSS: IDimSelectionSet;
Begin
    OLAP := UiErAnalyzer1.ErAnalyzer;
    Pivot := OLAP.Pivot;
    DimSS := Pivot.Selection;
    Pivot.BeginSelectionUpdate;
    //...
    //Change selection
    //...
    Pivot.EndSelectionUpdate;
    //Repeated getting of selection with rebuilt controlled dimensions
    DimSS := Pivot.Selection;
    Pivot.BeginSelectionUpdate;
    //...
    //Change selection in dimensions controlled by other dimensions
    //...
    Pivot.EndSelectionUpdate;
End Sub Button1OnClick;

Clicking the button disables selection in data source on selection changing in the table to accelerate working process.
