问题描述

Point_Of_Sale.CustomerInfoDataSet.ItemsDataTable items = new CustomerInfoDataSet.ItemsDataTable();
            itemsTableAdapter.Fill(items);

            //dataGridView1.DataSource = items;
            comboBox1.DisplayMember = "ItemName";
            comboBox1.DataSource = items;

推荐答案

好吧，我想尝试帮助您，因为我了解您拥有combobox和datagridview，并且需要从中获取选定的项组合到网格....这很容易:
首先，您必须取消组合的选中或选中的项目

ok man i want to try to help you, as i understand you have combobox and datagridview and you need to bing the selected items from combo to grid....it is easy man:
first you must ckeck the selected or checked items of the combo

List<string> lstString = new List<string>();
        foreach (ListItem lItem in combo.Items)
        {
            if (lItem.Selected)
            {
                lstString.Add(lItem.Value);
            }
        }

这样，您可以将选定项的ID组合添加到字符串列表(ID列表)中，然后必须获取这些ID的对象项:

in this way you are adding the IDs of the selected items in combo into a list of strings(list of IDs), then you have to get the objects item of these IDs:

List<items> lst = new List<items>();//insted of Items put your class
        Items item = new Items();
        foreach(string s in lstString)
        {
            item = lstItem.FirstOrDefault(p => p.ID == s);
            lst.Add(item);
        }</items></items>

现在，您必须绑定网格，以为其提供数据源，该数据源是项目列表
grid.DataSource = lst;

注意:当您绑定组合框时，必须将项目放入
session ["]为使数据保持活动状态，我们需要通过它进行搜索

最好的问候

now you must bind the grid , to give it datasource which is the list of items
grid.DataSource = lst;

Note: when you bind you combobox you have to put items in
session[""] in order to keep data alive becuese we need to search via it

best regards

好的，我想帮助您，据我所知您拥有combobox和datagridview，并且您需要将选定的项目从combo到grid ....很容易男人:

        foreach(string s in lstString)
        {
            item = lstItem.FirstOrDefault(p => p.ID == s);
