推荐答案

中传递和调用的，如果它是ASP，则可以将cardNumber作为参数发送，并在SQL语句中填充数据网格，您可以添加以下内容:
其中cardNumber =''+ Parameter_you_send +''
或对于C#Windows App.您可以将cardnumber值发送到datagrid表单中的Textbox或Label，并应用相同的"Where"语句.

Well, if it is ASP you can send the cardNumber as a Parameter and in your SQL statement for the filling of the datagrid you add something like:
Where cardNumber='' +Parameter_you_send+''
Or for C# Windows App. You can send the cardnumber value to a Textbox or Label in the datagrid Form, and apply the same ''Where'' Statement...

..

将您的卡号从第一种形式发送到第二种形式..

如果要使用数据表显示数据，请使用以下代码:

Hi there..

Send your card number from the first form to second form..

If you are using datatable to display the data then use this code:

DataRow[] dr=dataTable.Select("ColumName = "+cardNo);

一切顺利.

All the best..
