如何使用绑定源获取上一行 [英] How to get the previous row using a Binding Source

问题描述

当我想在我选择的行上显示数据时，如下所示

when i want to display data on my selected row coding like below

Dim barisBulan As bkuDataSet.bulanRow = CType(frmBulan.BulanBindingSource.Current, DataRowView).Row

然后如何显示所选列之前和之后的列？

then how to display the columns before and after of the selected column ?

有人可以帮我吗？

推荐答案

您好Senggel，

Hi Senggel,

我认为您的意思是前后行，而不是列...右？

I assume that you mean the before and after Row, not column ... right?

您可以使用BindingSource的.Position属性。由于我不确定您的DataTable名称是什么，我只是想使用任何DataTable。而且，我很抱歉我不太了解VB.NET，但你需要这样的东西：

You could use the .Position property of the BindingSource for that. Since I don't know for sure what your DataTable name is, I'm just going to use any DataTable. And, I'm sorry that I don't know much VB.NET, but you'd need something like this:

Dim dt As DataTable = CType(frmBulan.BulanBindingSource.DataSource, DataTable)
DataRow rowBefore = dt.DefaultView(frmBulan.BulanBindingSource.Position - 1).Row;
DataRow rowAfter = dt.DefaultView(frmBulan.BulanBindingSource.Position + 1).Row;
