Asp.net 从父GridView向嵌套GridView获取信息

我希望有人能帮我把数据从一个GridView转换到我在其中创建的另一个GridView。我试图将

wou id

字段从第一个GridView获取到第二个GridView的数据源（在第一个GridView中创建）

现在，在下面的代码中，“partsused”SqlDataSource的WHERE子句中有“tasks=tasks”，我希望它使用父GridView中的

wo_id

字段（从而显示特定工单的正确零件列表）

标准工单
查看可打印版本



会话（“workordrid”）=“”

没有记录任何部件

如果您能以某种方式精简代码，使其成为一个示例，演示您正在尝试做的事情，并清楚地显示问题所在（或您感到困惑的部分），这将非常有帮助。这是太多的代码了，有点难跳进去-这使得你不太可能得到一个好的答案（或者根本没有答案）。很抱歉，第一次使用它。（选择parts\u used\u id，dim\u users。[user\u name]，全名，wo_id作为任务，使用的事实零件。零件id，尺寸零件。零件编号+“”+尺寸零件。零件描述作为零件，数量，使用的事实零件的成本内部连接尺寸零件用户在尺寸用户上。[用户id]=使用的事实零件。[用户id]内部连接尺寸零件在尺寸零件上。零件id=使用的事实零件。零件id）a其中任务不为空且任务=任务“我需要更新的是什么？我需要从父GridView中获取任务id。有人需要我吗？您需要使用“编辑”按钮更新您的问题，并删除除演示问题的基本代码以外的所有内容。不太可能有人会通过挖掘所有这些代码来理解和解决您的问题。因此，为了您的最大利益，我们（回答者）可以更方便地帮助您=）查看有关为本网站编写好的示例代码的指导。
