如何从datagridview中的选定行获取数据

Question

我有一个新问题,我有一个datagridview,试着看图片,我想在datagridview中存在的单元格点击,然后点击输入到textbox1的数据,任何人都知道怎么在哪里？谢谢你的帮助

我被尝试如下,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

要获取单元格值,您需要直接从DataGridView1using e.RowIndex和e.ColumnIndexproperties 读取它.

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
