在数据网中,我需要显示数据电网中低效的字塔长度不明。 这一顺序是可能包含任何成果的LINQ询问的缓慢结果。
首先,我想到:VirtualMode,。 数据GridView是我所期待的,但似乎必须事先知道行文和列的数目。 我尝试增加一行和一栏,然后根据需要从CellValueNeed 但是,这并不奏效。
Is this even possible with VirtualMode? Or do I need to estimate how many rows are visible on the screen and manually build up the rows/columns? And if so, how do I ensure that a vertical scrollbar is present and react appropriately when a user uses it?
你只能收集一流的电离层,然后通知电网更新。 因此,你询问如何使用LINQ,并集中收集可能属于任何N号的此类资料。 在初始装货期间,可以按最初的记录,如1,000,将一些固定的收货款定在收集上,然后随着您的LINQ问询,在收集上加一行。
