更新された問題:
いくつかのページをマスター ページを使用するように変換したところ、問題なく動作しました。
子ページで request.form を実行すると (フォーム宣言はマスターページにあります)、null 値を取得します (Request.Form("field") を実行するだけで NULL が返されますが、マスターページの前に機能しました
注：マスターページを実装する前に、すべてのコードが正常に機能しました!!
ボタンのコードは次のとおりです。
<asp:Button ID="btnPACheck" runat="server" Text="<%$Resources:share,btnPACheck %>" onclick="btnPACheck_Click" />
ボタンの HTML ページのビュー ソースは次のとおりです。
<input type="submit" name="ctl00$ContentPlaceHolder1$btnPACheck" value="Continue" id="ctl00_ContentPlaceHolder1_btnPACheck" />
onclick コードは長いですが、次のように宣言されています (最初の行にはデバッグ行が配置されており、それに到達していません)。
protected void btnPACheck_Click(object sender, EventArgs e)
{
bool validPA = false;
マスターページは以下です。
