VB问题怎么编写代码可以使单击信息显示于文本框

编写了一下在datagridview控件中单击任一诗人信息，其个人简介详情显示于文本框中，但在执行时并不是每次点击都有效，该怎么调整
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
If e.RowIndex < 0 Then Exit Sub

    Dgvid = DataGridView1.Rows(DataGridView1.CurrentCell.RowIndex).Cells(0).Value
    TextBox1.Text = DataGridView1.Rows(DataGridView1.CurrentCell.RowIndex).Cells(0).Value
    TextBox2.Text = DataGridView1.Rows(DataGridView1.CurrentCell.RowIndex).Cells(1).Value

End Sub
