如何在c#中禁用可点击的datagridview中的空单元格

Question

这是我的代码，因此每次用户单击一行时都会转到 textbox，我的问题是当我单击一个空单元格时出现错误。如何禁用空单元格的可点击性？

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{           
   txt_voterid.Text = dataGridView1.SelectedRows[0].Cells[0].Value.ToString();
   txt_fname.Text = dataGridView1.SelectedRows[0].Cells[1].Value.ToString();
   txt_lname.Text = dataGridView1.SelectedRows[0].Cells[2].Value.ToString();
   txt_age.Text = dataGridView1.SelectedRows[0].Cells[3].Value.ToString();
   txt_vstatus.Text = dataGridView1.SelectedRows[0].Cells[4].Value.ToString();
   txt_uname.Text = dataGridView1.SelectedRows[0].Cells[5].Value.ToString();
   txt_pword.Text = dataGridView1.SelectedRows[0].Cells[6].Value.ToString();

}

Answer 1

替换此行

txt_voterid.Text = dataGridView1.SelectedRows[0].Cells[0].Value.ToString();

有了这个

if(!string.IsNullOrEmpty(Convert.ToString(dataGridView1.SelectedRows[0].Cells[0].Value)))
    txt_voterid.Text = Convert.ToString(dataGridView1.SelectedRows[0].Cells[0].Value);
