C# 如何让DataGridView自动完成只显示一列？

问题是除了第1列之外，自动完成也会显示。直到我在第1列中输入文本，然后它才会开始显示其他列

我的代码：

public AutoCompleteStringCollection ClientListDropDown()
{
    AutoCompleteStringCollection asc = new AutoCompleteStringCollection();
    try
    {
        Query = "Select top 5 title from customer "; // just removed  where name like '%" + txtDVNo.Text + "%' plz check
        cmd = new SqlCommand(Query, GlobalVars.conn);
        dr = cmd.ExecuteReader();
        if ((dr != null) && (dr.HasRows))
            while (dr.Read())
                asc.Add(dr.GetValue(0).ToString());
        dr.Close();
        cmd.Dispose();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
    return asc;
}

private void dgvDVDetails_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
    if (dgvDVDetails.CurrentCell.ColumnIndex == 1)
    {
        TextBox prodCode = e.Control as TextBox;
        if (prodCode != null)
        {
            prodCode.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
            prodCode.AutoCompleteCustomSource = ClientListDropDown();
            prodCode.AutoCompleteSource = AutoCompleteSource.CustomSource;

        }
    }
}

试试这个：

private void dgvDVDetails_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
    if (dgvDVDetails.CurrentCell.ColumnIndex == 1)
    {
        TextBox prodCode = e.Control as TextBox;
        if (prodCode != null)
        {
            prodCode.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
            prodCode.AutoCompleteCustomSource = ClientListDropDown();
            prodCode.AutoCompleteSource = AutoCompleteSource.CustomSource;

        }
    }
   else
   {
       TextBox prodCode = e.Control as TextBox;
       if (prodCode != null)
        {
            prodCode.AutoCompleteMode = AutoCompleteMode.None;
        }
   }
}
