Please help me here.

推荐答案

可以在运行时替换特定的 DataGridView 单元格 - 例如，在您想要在一个单元格中使用组合框的情况下，您可以拥有一个 DataGridViewTextBoxColumn 并替换第一行的单元格.像这样:

It is possible to replace specific DataGridView cells at run time - in your situation for example where you want a combobox in one cell you can have a DataGridViewTextBoxColumn and replace the cell in the first row. Something like this:

void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
    List<Book> books = new List<Book>();
    books.Add(new Book { bookID = 1, bookName = "Test-Driven Development (Kent Beck)" });
    books.Add(new Book { bookID = 2, bookName = "Refactoring (Martin Fowler)" });
    books.Add(new Book { bookID = 3, bookName = "Code Complete: 2nd Edition (Steve McConnell)" });
    DataGridViewComboBoxCell c = new DataGridViewComboBoxCell();

    c.DataSource = books;
    c.Value = 1;
    c.ValueMember = "bookID";
    c.DisplayMember = "bookName";

    dataGridView1.Rows[0].Cells[0] = c;
}

您也可以通过另一种方式执行此操作，将 DataGridViewComboBoxColumn 中的特定组合框单元格替换为 DataGridViewTextBoxCell.

You can also do this the other way and replace a particular combobox cell from a DataGridViewComboBoxColumn with a DataGridViewTextBoxCell.

有一点 - 虽然这会起作用，但更好的可用性可能只是将一些组合框设置为只读.

One thing though - while this will work, better usability might just come from setting some combo boxes to read only.
