如何从DataGridViewComboBoxCell中选择一个项目 [英] How to select an item from the DataGridViewComboBoxCell

问题描述

亲爱的所有人，

我将组合框绑定到了datagridview.此组合框从枚举中获取其值，如下所示:

Dear all,

I bounded combobox to the datagridview. This combobox takes its values from enum, like this:

DataGridViewComboBoxColumn comboColumn = new DataGridViewComboBoxColumn();
comboColumn.DataSource = Enum.GetNames(typeof(Duration));
comboColumn.Name = "Duration";
comboColumn.DisplayStyle = DataGridViewComboBoxDisplayStyle.ComboBox;
dataGrid.Columns.Add(comboColumn);

现在，我需要为datagridview中的每个组合框选择一个默认项，但是不必对所有组合框都使用相同的项.我该怎么办?


在此先谢谢您.

Now I need to select a default item for each of the combobox in the datagridview, but it''s not necessary to be the same item to all the combobox. How could I do that?


Thanks in advance.

推荐答案

您可以使用组合框列的DefaultCellStyle.NullValue和DefaultCellStyle.DataSourceNullValue属性.代码示例为:

You can use the DefaultCellStyle.NullValue and DefaultCellStyle.DataSourceNullValue properties of the combo box column. Code sample is:

comboColumn.DefaultCellStyle.NullValue = "dataToStore";
comboColumn .DefaultCellStyle.DataSourceNullValue = "dataToStore";
