c# - 同じページに複数の Gridview があり、複数の GridViewCommandEventArgs がある場合、buttonfield は間違った Gridview からインデックス/ID を取得します

Question

だから私はこれらの 2 つの Gridviews を持っています。「GridView1」という名前の最初のものは正常に機能しますが、「Gridview2」という名前の2番目のものは、ButtonFieldをクリックしてGridView ID列セル内からIDを取得すると、正しい行インデックスを取得しますが、間違ったGridViewから、機能 ButtonField のコードが GridViewCommandEventArgs _RowCommand コードブロック内にある 'GridView2' ではなく 'GridView1' から取得します。e.CommandSource(.ID.toString()) でさえ、それが GridView2 からのものであると言っていますが、私が取得した列 ID は最初のものから取得されます. 2 つの GridView は同一ですが、2 番目の GridView にはより多くの ButtonFields があり、最初の GridView のカスタムビューです。選択した ID のみが 2 番目の GridView(GridView2) に表示されます。これは私の最初の投稿のようなものです。あなたの助けに感謝します。Googleで検索してみましたが、私の問題は非常に具体的なようで、オンラインで見つけやすくするのは難しいです.

C# コード: 役立つ場合は、いくつかのグローバル変数:

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;

    getCustomView = null;
}

しかし、主な問題は、次のコードブロックにありました。

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) { }
    }

そのため、カスタムビューが null になったときにデフォルトで最初のデータソースにならず、別のデータソースから同じ ID を取得しているように見えるように、より良い select ステートメントを考え出す必要があります。インラインスクリプトを使用する必要があるかもしれません.

c# - 同じページに複数の Gridview があり、複数の GridViewCommandEventArgs がある場合、buttonfield は間違った Gridview からインデックス/ID を取得します
