如何更新datagridview中的记录? [英] how to update record in datagridview?

问题描述

Dim table As DataTable = dataSet.Tables("Customers")

' First process deletes.
dataSet.Update(table.Select(Nothing, Nothing, _
  DataViewRowState.Deleted))

' Next process updates.
adapter.Update(table.Select(Nothing, Nothing, _
  DataViewRowState.ModifiedCurrent))

' Finally, process inserts.
dataAdapater.Update(table.Select(Nothing, Nothing, _
  DataViewRowState.Added))

有人可以解释什么是数据集和适配器吗?是数据库数据集吗?

can someone explain what is the dataset and adapter? is it the db dataset?

我需要在使用它之前先声明它吗?

i need to declare it first before using it?
