我有一个新问题，我有一个datagridview，尝试查看图片，我想要点击datagridview中存在的单元格，然后点击输入textbox1的数据，有谁知道如何如何？谢谢你帮助我
I was tried like below, but its not work
我像下面一样尝试过，但它不起作用
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
If Me.DataGridView1.RowCount > 0 Then
TextBox1.Text = Convert.ToString(Me.DataGridView1.SelectedRows)
'TextBox1.Text = Me.DataGridView1.Rows(Me.DataGridView1.row).Cells(1).Value
End If
End Sub

To get the cell value, you need to read it directly from DataGridView1using e.RowIndexand e.ColumnIndexproperties.
要获取单元格值，您需要直接从DataGridView1usinge.RowIndex和e.ColumnIndexproperties 中读取它。
Eg:
例如：
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim value As Object = DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value
If IsDBNull(value) Then
TextBox1.Text = "" ' blank if dbnull values
Else
TextBox1.Text = CType(value, String)
End If
End Sub

I was having the same issue and this works excellently.
我遇到了同样的问题，这非常有效。
Private Sub DataGridView17_CellFormatting(sender As Object, e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView17.CellFormatting
'Display complete contents in tooltip even though column display cuts off part of it.
DataGridView17.Rows(e.RowIndex).Cells(e.ColumnIndex).ToolTipText = DataGridView17.Rows(e.RowIndex).Cells(e.ColumnIndex).Value
End Sub
