您正在设置 DataPropertyName 错误。您将一个列表绑定到网格，将一个列表绑定到列。 DisplayMember 和 ValueMember 是列名/绑定到该列的项目的属性。 DataPropertyName 是绑定到网格的项目的列/属性的名称。就您而言，在我看来 DataPropertyName 应该设置为 Condition。

You're setting the DataPropertyName incorrectly. You bind one list to the grid and one to the column. The DisplayMember and ValueMember are names of columns/properties of the items bound to the column. The DataPropertyName is the name of a column/property of the items bound to the grid. In your case, it looks to me like DataPropertyName should be set to "Condition".
