我搞乱了下面的功能，但失败了。你能不能帮我修改下面的功能。因此，通过此我将能够通过搜索站点值（如站点 1、站点 2 等）来获取行索引。
Function FindValue(ByRef dgv As DataGridView, ByVal metric_key As Object) As DataGridViewRow
For Each row As DataGridViewRow In dgv.Rows
If row.Cells.Item("metric_value").Value = metric_key Then
Return row
End If
Next
Return Nothing
End Function
结束函数
Usage of function dataGridView1.FindValue(1)
函数 dataGridView1.FindValue(1) 的使用
Finally I found the way by my self to find the rowindex by value
最后我自己找到了按值查找行索引的方法
Here is mine code
这是我的代码
Dim rowindex As String
For Each row As DataGridViewRow In DataGridView1.Rows
If row.Cells.Item("yourcolumnnamehere").Value = "valueforwhichyouaresearching" Then
rowindex = row.Index.ToString()
MsgBox(rowindex)

Maybe you mean ...
也许你的意思是...
For Each cell In DataGridView1.SelectedCells
If Not FirstValue Then
TextBox1.Text += cell.Value.ToString() & ", "
Else
TextBox1.Text += cell.Value.ToString()
FirstValue= False
End If
Next
