我在winforms中有一个DataGridView,它包含一个组合框列。 gridview以编程方式填充,并且在开始时为空。 “list”是包含自定义对象的列表。 Value1 / 2/3对每一行都是唯一的。

int[] array = new[] {value1,value2,value3}
for (int i = 0; i < list.Count; i++)
{
    DataRow newrow = MyDataTable.NewRow();
    newrow["idColumn"] = list[i].Customer_id;
    newrow["dateoforderColumn"] = list[i].Customer_date;
    newrow["commColumn"] = list[i].Customer_comment;
    // This is what I want, and can't get to work.
    newrow["comboColumn"] = array;
    // I have also tried (newrow["comboColumn"] as DataGridViewComboColumn).DataSource
    // but it didn't work either.

    MyDataTable.Rows.Add(newrow);
}

如何填充新创建的组合框?另外,我需要在for循环中执行它,因为我需要索引来获取数据。

从代码的外观来看,您只需要设置一个值数组。在这种情况下,您只需要为列设置一次,而不是为每一行设置它,我通常在构造函数中或在填充行之前执行此操作。

        //Clear any junk items that may have been there from the designer or previous view
        ((DataGridViewComboBoxColumn)MyDataTable.Columns["comboColumn"]).Items.Clear();
        //Add you new values
        ((DataGridViewComboBoxColumn)MyDataTable.Columns["comboColumn"]).Items.AddRange(array);

然后设置新行的单元格的值

        //Set value to be selected in new row
        newrow["comboColumn"] = list[i].Customer_value;
