C# 如何在datagridview c中验证行#

为什么验证总是拒绝编辑（行

e.Cancel=true；

）

准确地验证一行是什么意思？您能更具体一点吗？如果单元格值为空，则不应转到新行。请检查我的代码并告诉我更正。您需要更具体地说明您需要的内容以及您已经/已经尝试的内容。事实上，甚至尝试分析问题都非常困难。请添加一个描述性的解释，说明您需要什么以及为什么它不起作用。

    private void dataGridView1_RowValidating(object sender, DataGridViewCellCancelEventArgs e)
    {
        DataGridViewRow row = dataGridView1.Rows[e.RowIndex];
        DataGridViewCell Docnamecell = row.Cells[dataGridView1.Columns[0].Index];
        DataGridViewCell Gendercell = row.Cells[dataGridView1.Columns[1].Index];
        DataGridViewCell Addresscell = row.Cells[dataGridView1.Columns[2].Index];
        DataGridViewCell Contactnocell = row.Cells[dataGridView1.Columns[3].Index];
        DataGridViewCell Datecell = row.Cells[dataGridView1.Columns[4].Index];
        e.Cancel = !(IsDoc(Docnamecell) && IsGender(Gendercell) && IsAddress(Addresscell) && IsContactno(Contactnocell) && IsDate(Datecell));
        e.Cancel = true;
    }
    private Boolean IsDoc(DataGridViewCell cell)
    {
        if (cell.Value == null)

        return false;
