DataGrid上的“插入”按钮有什么意义 [英] What is the point of the Insert button on a DataGrid

问题描述

如果在创建DataGrid时，设置

 <   asp：commandfield     showinsertbutton   =  true    /  >  
 

您获得了一个插入内容每条记录旁边的按钮。这是如何运作的？单击它时，会调用后面的代码，但新记录的值只是单击按钮的行中的值，因此我看不出如何创建这样的新记录。 />


我必须在这里找不到简单的东西。



非常感谢解释（可能会阻止我疯了）。

参见来自给定链接的InsertCommand

 insertcommand =  插入[客户]（[客户名称]，[公司名称]，[城市]，[邮政编码]，[国家]）值（@CustomerID，@ CompanyName，@ City，@ PostCode，@ Country] 
 connectionstring =  <％ 

ConnectionStrings：NorthWindConnectionString％>

Hi,

If when creating a DataGrid, you set the

<asp:commandfield showinsertbutton="true" />

you get an insert button next to each record. How does this work? When you click it, the code behind is called, but the values for the new record are simply the ones from the row in which the button was clicked, so I don't see how you can create a new record like this.

I must be missing something simple here.

An explanation would be very much appreciated (and may stop me going insane).


Kind wishes ~ Patrick

See InsertCommand from the given link
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.commandfield.showinsertbutton(v=vs.110).aspx[^]

insertcommand="Insert Into [Customers]([CustomerID], [CompanyName], [City], [PostalCode], [Country]) Values (@CustomerID, @CompanyName, @City, @PostalCode, @Country)"
       connectionstring="<%

ConnectionStrings:NorthWindConnectionString%>" runat="server">
