如何使用 PowerApps 中的输入字段和下拉菜单过滤项目？

Question

我已将 Excel table 连接到 PowerApps 中的库控件。我有一个用于 'Manager' 列的 select 值的下拉框和一个输入员工姓名的输入字段。我试过-

Filter(Table1,StartsWith(Name,empSearchbox.Text) && (Manager = dropdownManager.Selected.Value ||dropdownManager.Selected.Value=Blank()))

这给我错误-

    Issue 
        Incompatible types for comparison. These types can't be compared: Text, Error.
        We can't evaluate your formula because the values being compared in the formula aren't the same type.

第二个错误：

        Name isn't valid. This identifier isn't recognized. 
        This error appears most commonly when a formula refers to something that no longer exists (for example, a control that you've deleted). 
        Location No

过滤器功能的第一部分单独工作。编辑：= 和 .Value 带有红色下划线。

Answer 1

假设您的 dropdownManager 字段有一个空白值作为 initial/unselected 值，尝试：

Filter(
  Table1,
  StartsWith(
    Name,
    empSearchbox.Text
  ) && ( Manager = dropdownManager.Selected.Result || isBlank( dropdownManager.Selected.Result)
  )
)

这将帮助您入门 ;-)
