我有一个包含两个按钮和一个包含 6 列的数据网格的屏幕。当按下按钮 1 时，它会在行中显示第 1 到第 4 列的数据。当我按下按钮 2 时，我希望我的应用程序填充行中的剩余列（即第 5 列和第 6 列）。

解决方案可能很明显，但我不确定如何解决它。

编辑：对不起，我之前忘了提，当我点击第二个按钮时，数据出现在正确的位置，即最后两列。除非它不在同一行。数据显示在下一行。

这是我的代码：

Private Sub btnClockIn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClockIn.Click

Homescreen.DataGridViewEmployee.ColumnCount = 6
Homescreen.DataGridViewEmployee.Columns(0).Name = "Employee Number"
Homescreen.DataGridViewEmployee.Columns(1).Name = "Day"
Homescreen.DataGridViewEmployee.Columns(2).Name = "Week Number"
Homescreen.DataGridViewEmployee.Columns(3).Name = "Time In"
Homescreen.DataGridViewEmployee.Columns(4).Name = "Time Out"
Homescreen.DataGridViewEmployee.Columns(5).Name = "Hours"

Dim row As String() = New String() {ENumber, day, WeekNum, StartTime, "", ""}
Homescreen.DataGridViewEmployee.Rows.Add(row)
Homescreen.DataGridViewEmployee.ReadOnly = True

Private Sub btnClockOut_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClockOut.Click

Homescreen.DataGridViewEmployee.ColumnCount = 6
Homescreen.DataGridViewEmployee.Columns(0).Name = "Employee Number"
Homescreen.DataGridViewEmployee.Columns(1).Name = "Day"
Homescreen.DataGridViewEmployee.Columns(2).Name = "Week Number"
Homescreen.DataGridViewEmployee.Columns(3).Name = "Time In"
Homescreen.DataGridViewEmployee.Columns(4).Name = "Time Out"
Homescreen.DataGridViewEmployee.Columns(5).Name = "Hours"

Dim row As String() = New String() {"", "", "", "", EndTime, Diff}
Homescreen.DataGridViewEmployee.Rows.Add(row)
Homescreen.DataGridViewEmployee.ReadOnly = True

问题是您使用的rows.add()方法的第二个按钮被命名为添加到一行。如果要添加到最后一行，则需要使用获取最后一行，rows(rows.Count -1)然后编辑列表中的相关字段

Dim row as DataGridViewRow = rows(rows.Count -1)
row(4) = EndTime
row(5) = Diff

无需在每次按下按钮时设置数据网格视图的属性，因此可以删除所有关于列名的代码，只读设置也可以。
