Getting row number in a DataGridView
提问by Cyclone
How do you get row number DataGridView cell? Specifically, if a user has selected a single cell, how can you get that row number? It needs to access a particular cell based on what the user has selected.
你如何获得行号 DataGridView 单元格？具体来说，如果用户选择了单个单元格，您如何获得该行号？它需要根据用户选择的内容访问特定的单元格。
I know that the RemoveAt method can be used to remove at the Focus, but you cannot get the row number at focus apparently?
我知道 RemoveAt 方法可用于在焦点处删除，但您显然无法获得焦点处的行号？
Thanks for the help!
谢谢您的帮助！

You can simply use RowIndexon the current cell:
var row = dataGridView1.CurrentCell.RowIndex;

this one works fine .
这个很好用。
Private Sub DataGridView1_RowPrePaint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewRowPrePaintEventArgs) Handles DataGridView1.RowPrePaint
If e.RowIndex >= 0 Then
Me.DataGridView1.Rows(e.RowIndex).Cells(0).Value = e.RowIndex + 1
End If
End Sub

If you in event procedure of datagridview you will found "e As DataGridViewCellEventArgs" you can get row number with e.RowIndex and column number with e.ColumnIndex
如果您在 datagridview 的事件过程中，您会发现“e As DataGridViewCellEventArgs”，您可以使用 e.RowIndex 获取行号，使用 e.ColumnIndex 获取列号
Private Sub myDGV_CellLeave(sender As Object, e As DataGridViewCellEventArgs) Handles myDGV.CellLeave
Dim myRow As Integer = e.RowIndex
End Sub
And if you in normal procedure you can get row number like this:
如果你在正常程序中你可以得到这样的行号：
Private Sub btnGetRow_Click(sender As Object, e As EventArgs) Handles btnGetRow.Click
dim myRow1 as Integer = 0
dim myRow2 as Integer = 0
myRow1 = myDGV.CurrentCell.RowIndex
myRow2 = myDGV.CurrentRow.Index
End Sub

It is nearly the same but you may also use this solution:
它几乎相同，但您也可以使用此解决方案：
var row = dataGridView1.CurrentRow.Index

Another way if you need to track user interaction with a DataGridView: In my case there is extra processing in some generic functions that use the Me.I_SelCol and Me.I_SelRow column and row coordinates, but I haven't shown that because it's not relevant to the OP.
如果您需要跟踪用户与 DataGridView 的交互，另一种方法是：在我的例子中，在一些使用 Me.I_SelCol 和 Me.I_SelRow 列和行坐标的通用函数中有额外的处理，但我没有显示，因为它不相关到 OP。

最好的问候，罗布
Private Sub I_DataGridView_CurrentCellChanged(sender As Object, e As EventArgs) Handles I_DataGridView.CurrentCellChanged
If Me.I_DataGridView.CurrentCellAddress.X < 0 Or Me.I_DataGridView.CurrentCellAddress.Y < 0 Then Exit Sub
' The Windows Me.I_DataGridView object will have already deselected the current cell and selected the
' new cell as per user navigation using mouse or cursor keys. We just need to store the current
' co-ordinates for the currently selected cell.
Me.I_SelCol = Me.I_DataGridView.CurrentCellAddress.X
Me.I_SelRow = Me.I_DataGridView.CurrentCellAddress.Y
Exit Sub
