Add item to DataGridViewComboBoxColumn
提问by Dennys
I have a DataGridView and I change one column to a DataGridViewComboBoxColumn. And I can edit the Items to put some data in it and it works.
我有一个 DataGridView，我将一列更改为 DataGridViewComboBoxColumn。我可以编辑项目以将一些数据放入其中并且它可以工作。
But I want to put the Items in program, therefore, I try to use dataGridView1.Columns["drop_column"]. But it doesn't have a Items
但是我想将项目放在程序中，因此，我尝试使用 dataGridView1.Columns["drop_column"]。但它没有 Items
I found this article but it's to create a new column but I already have a column Add items to DataGridViewComboBoxColumn in DataGridView during runtime.
我找到了这篇文章，但它是为了创建一个新列，但我已经有一个列Add items to DataGridViewComboBoxColumn in DataGridView during runtime。
Update: thanks to Ginosaji and Dona, I add a cast and it works now.
更新：感谢 Ginosaji 和 Dona，我添加了一个演员，现在可以使用了。
((DataGridViewComboBoxColumn)dataGridView1.Columns["drop_column"]).Items.Add("1");
((DataGridViewComboBoxColumn)dataGridView1.Columns["drop_column"]).Items.Add("2");
((DataGridViewComboBoxColumn)dataGridView1.Columns["drop_column"]).Items.Add("3");

Here is an example:
下面是一个例子：
DataGridViewComboBoxCell CBCell = new DataGridViewComboBoxCell();
CBCell = DataGridView1.Rows(0).Cells("Your column name");
CBCell.Items.Add("Your item here");
