我有“区域”选项卡，其中包含带有一些计算的网格。该计算取决于选择的区域。接下来是情况：一个对象可以有多个区域，当我打开“区域”选项卡时，它计算得很好，但是当我在对象中将区域从一个更改为另一个时，计算中的值保持不变。换句话说：它没有得到更新。我正在使用这段代码：

[Control("TabPage")]
class TabLineAreaGroup
{
    public void pageActivated()
    {
        PMCContractArea contractArea;
        AmountMST sumContractArea;

        super();

        pmcContractLine_ds.readCommonAreas(pmcContractLine);
        h1_h2.realValue(pmcContractLine_ds.h1_h2(pmcContractLine));
        efa.realValue(pmcContractLine_ds.efa(pmcContractLine));
        bfa.realValue(pmcContractLine_ds.bfa(pmcContractLine));
        mfa.realValue(pmcContractLine_ds.mfa(pmcContractLine));
        sumArea.realValue(h1_h2.realValue() + efa.realValue() + bfa.realValue() + mfa.realValue());

        while select AreaSelector, sum(RentalValue)
            from contractArea
            group by AreaSelector
            where contractArea.ContractId == pmcContract.ContractId
                && contractArea.RentalObjectId == pmcContractLine.RentalObjectId
        {
            sumContractArea += contractArea.RentalValue;
            switch (contractArea.AreaSelector)
            {
                case PMEAreaSelector::CommonAreaBuilding :
                    contractAreaBFA.realValue(contractArea.RentalValue);
                    break;
                case PMEAreaSelector::CommonAreaSection :
                    contractAreaEFA.realValue(contractArea.RentalValue);
                    break;
                case PMEAreaSelector::PrimaryArea, PMEAreaSelector::SecondaryArea :
                    contractAreaH1_H2.realValue(contractArea.RentalValue);
                    break;
                case PMEAreaSelector::CommonAreaFixed :
                    contractAreaMFA.realValue(contractArea.RentalValue);
                    break;
            }
        }
        contractAreaSum.realValue(sumContractArea);
    }

}

我需要在这段代码中添加什么，所以当更改区域以更新网格中的计算时？

对于 Dynamics 365，Microsoft 有时会弃用方法并且不会更新文档，或者它们会保留可用的方法，但尚未实现它们。

对于 D365，您可能需要在Tab控件上使用事件处理程序方法。

下面是一个示例，我刚刚创建了一个form带有几个Tab+Grid的数据源CustGroup

/// <summary>
///
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
[FormControlEventHandler(formControlStr(TestForm, FormTabControl1), FormControlEventType::TabChanged)]
public static void FormTabControl1_OnTabChanged(FormControl sender, FormControlEventArgs e)
{
    // You can interact with FormRun
    FormRun                             formRun                             = sender.formRun();

    // You can interact with the actual control (from event handler)
    FormTabControl                      formTabControl                      = sender is FormTabControl ? sender as FormTabControl : null;

    // You can get events
    FormTabControlTabChangedEventArgs   formTabControlTabChangedEventArgs   = e is FormTabControlTabChangedEventArgs ? e as FormTabControlTabChangedEventArgs : null;

    // You can interact with the tab pages
    if (formTabControl && formTabControlTabChangedEventArgs)
    {
        FormControl         fc = formTabControl.controlNum(formTabControlTabChangedEventArgs.oldTab());
        FormTabPageControl  tabPageOld = formTabControl.controlNum(formTabControlTabChangedEventArgs.oldTab());
        FormTabPageControl  tabPageNew = formTabControl.controlNum(formTabControlTabChangedEventArgs.newTab());

        info(strFmt("Tab changed from %1 to %2", tabPageOld.caption(), tabPageNew.caption()));
    }

    // You can interact with datasources
    FormDataSource fdsCustGroup = formRun.dataHelper().FindDataSource('CustGroup');
}
