所以我有这两个Gridviews。第一个名为“GridView1”的工作正常，但第二个名为“Gridview2”，当我单击 ButtonField 以从 GridView ID 列单元格内部获取 ID 时，它获取正确的行索引，但来自错误的 GridView，它从 'GridView1' 而不是 'GridView2' 获取它，其中 ButtonField 功能的代码位于 GridViewCommandEventArgs _RowCommand 代码块内。我一生都无法弄清楚为什么它是从第一个获取的，即使 e.CommandSource(.ID.toString()) 说它来自 GridView2，但是我得到的列 ID 是从第一个获取的. 这两个 GridView 是相同的，除了第二个有更多的 ButtonField 并且是第一个的自定义视图，只有选定的 ID 显示在第二个 GridView(GridView2) 上。这是我的第一篇文章，非常感谢您的帮助。尝试搜索谷歌，但我的问题似乎很具体，很难在网上找到更广泛的内容。

C# 代码：一些全局变量（如果有帮助）：

public partial class userArea : System.Web.UI.Page {

static string getCustomView;
static string hash;
static string authNum;
static string addToMyCustomView;
static string getDistinctArray;
static string getFirstName;
static string getLastName;
static string getUsernameToAddToComp;
static string getNotes;
static string getUserSessionStatus;

        catch (Exception ex) { }
    }


    getCustomView = null;
}

但主要问题在于这里的这段代码：

if ((getCustomView == null) )
    {
        //Perform the custom view with the select command
        SqlDataSource2.SelectCommand = "SELECT lheID, lhewirelessGiant, lheFName, lheInitials, lheLName, lhePrimaryEmail, lheDisplayName, lheNameID, lheWhosLookingAtthis FROM lhentries WHERE lheID  = 0  AND lheCompleted = 'False' ORDER BY lheID DESC; ";
    }
    else
    {

        try
        {

            //Perform the custom view with the select command
            SqlDataSource2.SelectCommand = "SELECT lheID, lhewirelessGiant, lheFName, lheInitials, lheLName, lhePrimaryEmail, lheDisplayName, lheNameID, lheWhosLookingAtthis FROM lhentries WHERE lheID IN (" + getCustomView + ")  AND lheCompleted = 'False' ORDER BY lheID DESC; ";
        }
        catch (Exception ex) { }
    }

所以现在我必须想出一个更好的选择语句，这样当自定义视图变为空时，它不会默认为第一个数据源，看起来它从不同的数据源获取相同的 id。可能必须使用一些内联脚本，我仍在接受意见，但这可能应该关闭这个问题。
