问题描述
使用ClientDataSet在最后一条记录之后插入的代码应该是什么?
What should be the code for inserting after the last record using the ClientDataSet?
我尝试了以下操作:
cdsSomething.Last; cdsSomething.Insert:但是看起来它代替了最后一条记录.我确信必须有一个快速的代码.
But it appears it replaces the last record instead. I am sure there must be a quick code for this.
推荐答案将记录追加到数据集末尾的方法(更不用说任何索引了)是 Append .您甚至无需先致电 Last .
The method to append a record to the end of the Dataset (let alone any index) is Append. You don't even need to call Last before.
cdsSomething.Append;插入在所选记录之前插入一行,因此对于您的代码,新记录应成为倒数第二个记录.
Insert inserts a row before the selected record, so with your code, the new record should become the second to last record.
