解决方案

您如果条件是如果用户当前所选择的第三列只是检查。

你想使所有列编辑？或当前所选行中只有一个细胞？如何编辑由另一个按钮关闭该表格触发？在这种情况下，当编辑被激活的任意单元格可以选择？

您需要将索引到正确的列，并将其设置有自动完成。

I've got my DataGridView binding correctly to my datatable however I'm trying to get autocomplete to work correctly for one of the textbox columns. The autocomplete is working but I'm trying to restrict it to only one column on the datagridview. At the moment it either does it for every column, or nothing at all. Any ideas? Code below.

private void dataGridDetail_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        if (dataGridDetail.CurrentCell.ColumnIndex == 2)
        {
            var source = new AutoCompleteStringCollection();
            String[] stringArray = Array.ConvertAll<DataRow, String>(products.Select(), delegate(DataRow row) { return (String)row["code"]; });
            source.AddRange(stringArray);

            TextBox prodCode = e.Control as TextBox;
            if (prodCode != null)
            {
                prodCode.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
                prodCode.AutoCompleteCustomSource = source;
                prodCode.AutoCompleteSource = AutoCompleteSource.CustomSource;

            }
        }
    }

解决方案

Your if condition is just checking if the user has currently selected the third column.

Do you want to make all that column editable? or just one cell in the currently selected row? How is the edit triggered by another button off the form? In this case when the edit becomes active any cell could be selected?

You will need to index into the correct column and set it to have the autocomplete on.
