[英]MS Access 2007 reference subform control on tabbed control returning null
I have a subform reference returning Null where the textbox has a value in it. 我有一个返回Null的子窗体引用,其中文本框具有一个值。 The code I am using is:
我使用的代码是:
End Date: [Forms]![ReportCentre]![NavigationSubform].[Form]![txtEndDate]
This is in a tabbed control, but I could not find the .Pages property referred to in a similar question. 这是在选项卡式控件中,但是找不到类似问题中提到的.Pages属性。
The subform being referenced is [LODForm], and the tab control (page area) is [NavigationSubform] 被引用的子表单是[LODForm],而选项卡控件(页面区域)是[NavigationSubform]
Why is this returning Null? 为什么返回Null?
The subform belongs to the form, not the tab control. 子窗体属于窗体,而不是选项卡控件。 The tab control only hides/displays other controls.
选项卡控件仅隐藏/显示其他控件。 And you will reference the subform control, not the subform.
您将引用子窗体控件,而不是子窗体。 Thus:
从而:
End Date: [Forms]![ReportCentre]![NameOfYourSubformControl].[Form]![txtEndDate]
Inserted name of subform control: 插入的子窗体控件的名称:
End Date: [Forms]![ReportCentre]![NavigationSubform].[Form]![txtEndDate]
