我有一个数据网格,有一个装束子,含有精度值。 用户可以选择其中一种有效术语。 然而,我面临一个奇怪的问题——当你在选定的价值中点击 com器,把一些how光树脂放在名单上的第一.上,从而失去了已经选定的树脂。 看一看情况
这是对窗口的初步看法:
This is when I select similar column with a double value in it(note the selection in combobox s list)
这正是我选择一个具有贬值价值的栏目。 甄选(第293号)缺失
The Code I use:
public Form1()
{
InitializeComponent();
dgwResult.AutoGenerateColumns = false;
var list = new List<string>(){"A", "B", "C", "D"};
var list2 = new List<double>();
var list3 = new List<decimal>();
for (int i = 0; i < 300; i++)
{
list2.Add((double)i);
list3.Add((decimal)i);
}
dgw_2.DataSource = list;
dgw_2.DataPropertyName = "two";
dgw_3.DataSource = list2;
dgw_3.DataPropertyName = "three";
dgw_4.DataSource = list3;
dgw_4.DataPropertyName = "four";
DataTable dt = new DataTable();
dt.Columns.Add("one", typeof(string));
dt.Columns.Add("two", typeof(string));
dt.Columns.Add("three", typeof(double));
dt.Columns.Add("four", typeof(decimal));
dt.Rows.Add(new object[] { "akjsgdf", "A", 10.0, 10.0m });
dt.Rows.Add(new object[] { "akjsgdf", "B", 15.0, 15.0m });

难道有人可以指出,为什么行为如此奇怪? Maybe 在这里,我没有简单的东西?
