C# 代码隐藏中GridView的数据源

我已经有一个填充的GridView运行良好，但现在我需要设置一些参数。我正在HTML页面中填充gridview。以下是我的完整GridView HTML代码 希望你们不要认为它是垃圾邮件，因为它是一个巨大的代码。

如何在Aspx.cs文件中执行所有这些操作，是否创建数据集并将其设置为GridView的数据源，以及如何将值设置为列？谢谢 Obs：我的手机上还有两个Buton。

[注释]-其他解决方案是在下面的代码中传递参数，是否可能？我需要传递会话的值

您也可以在代码隐藏页面中完成所有这些任务。 请参考以下链接以进一步参考

我终于找到了答案

我的aspx代码：这是我的Select命令，参数为@club

工作刚刚完美xD希望它能帮助其他人。。。再见，伙计们

我现在就看。。。但是告诉我。我有两个按钮，这些按钮有功能。我也可以做吗？使用您刚才发送给我的链接中的方法感谢这些功能是什么，您对这两个按钮的期望是什么。它们都会打开一个包含行详细信息的新页面。。。一个是查看，另一个是编辑。打开一个新的windos，一个我只看到详细信息，另一个我可以编辑取消状态。您可以在代码隐藏页面中执行这两项功能。您可以根据为按钮指定的命令名从rowcommand事件调用相同的页面。例如：item.commanname=visualizar然后执行与现在相同的操作，我现在也是这样做的。。。我只需要知道如何以现在的方式将参数值传递给gridview，我想这会更容易。。。
