c#数据绑定之删除datatable数据示例

c#数据绑定之将datatabel的data添加listview中，简要的通过代码应用了datatable，datatablecolumns,datatablerow类，通过ui界面的textbox向datatable中添加数据然后响应到listview控件中。在本实例中主要针对如何删除datatable的纪录，并同步到listview中。

首先，对ui做一些改动，最终界面如下图所示。主要是在listview 中添加了checkbox控件。

在listview中添加checkbox 的xaml 代码：

<gridviewcolumn x:name="gvcselectall">
                                <gridviewcolumn.header>
                                    <checkbox content="全选" />
                                </gridviewcolumn.header>
                                <gridviewcolumn.celltemplate>
                                    <datatemplate>
                                        <checkbox />
                                    </datatemplate>
                                </gridviewcolumn.celltemplate>
                            </gridviewcolumn>

在listview中items添加button 的xaml 代码：

<gridviewcolumn header="操作">
                                <gridviewcolumn.celltemplate>
                                    <datatemplate>
                                        <button content="删除" minwidth="50" margin="2" name="btndelete" click="btndelete_click" commandparameter="{binding path=autoid}"/>
                                    </datatemplate>
                                </gridviewcolumn.celltemplate>

其次，对button添加

click="btndelete_click"

事件，事件的响应的c# 后台代码为：

private void btndelete_click(object sender, routedeventargs e)
        {
            button b = sender as button;
            int32 autoid = convert.toint32(b.commandparameter);
            delmember(commodity, autoid);
            lstdisplay.datacontext = commodity;
            lstdisplay.items.refresh();

        }

        private datatable delmember(datatable table,int32 laction)
        {
            //deleting  a existed row in datatable commodity;
            datarow delrow = table.rows.find(laction);
            table.rows.remove(delrow);
            return table;
        }
