ユーザーがグリッドビューのアクションボタンをクリックすると開くはずのアクション確認Javascriptポップアップボックスがあります。私の問題は、サブのコード全体が実行されるまでポップアップボックスが開かず、値を割り当てる必要がある変数が手遅れになるまで値が割り当てられないことです。ポップアップを開いて、サブが終了する前にユーザーがDelUserConfirm変数にデータを入力できるようにするにはどうすればよいですか？助けてくれてありがとう！私のコードは次のとおりです。

Sub Gridview_RowCommand（ByVal sender As Object、ByVal e As GridViewCommandEventArgs）

    Dim currentcommand As String = e.CommandName
    Dim index As Integer = Convert.ToInt32(e.CommandArgument)
    Dim cell As GridViewRow = grdUsers.Rows(index)
    Dim currUserID As String = grdUsers.Rows(index).Cells(0).Text

    If e.CommandName = "DelUser" Then

        Dim DelUserConfirm As String = Request.Form("confirm_value")

        If (Not ClientScript.IsStartupScriptRegistered("alert")) Then

            Page.ClientScript.RegisterStartupScript(GetType(action), _
                "alert", "Confirm()", True)

        End If

        If DelUserConfirm = "Yes" Then

            cmd.Connection = conn
            conn.Open()
            cmd.CommandText = "DELETE FROM USERS WHERE USER_NAME = '" + currUserID + "'"
            cmd.ExecuteNonQuery()
            conn.Close()
            dtUsers.Rows(index).Delete()
            grdUsers.DataSource = dtUsers
            grdUsers.DataBind()

        End If

        Exit Sub

    End If

    If e.CommandName = "EditUser" Then

        Session("EditUserPerms") = dtUsers(index)
        Session("UserPerms") = dtUserPerms
        Response.Redirect("AddEditUser.aspx")

    End If

End Sub
