FormView在bind中调用字符串函数

我的网站内有一个编辑用户页面(edituser.aspx)。用户名和密码放在Access数据库中,我在FormView中显示它们。像这样:

<asp:FormView 
ID="EditForm" 
runat="server" 
DefaultMode="Edit">
    <EditItemTemplate>
        <strong>username:</strong><br />
        <asp:TextBox ID="usernameIDTextBox" runat="server" Text='<%# Bind("usernameID") %>' /><br />

        <strong>Password:</strong><br />
        <asp:TextBox ID="passwordIDTextBox" TextMode="password" runat="server" Text='<%# Bind("passwordID") %>' /><br />
    ... .

我在数据库中加密了密码但是虽然我有解密功能,但是我不知道如何在绑定短语中使用它。例如我试过

 <%# decrypt(Bind("passwordID")) %>

这不起作用。

注意:我使用asp.net 3.5,这是我在edituser.aspx.vb中解密的函数:

Public Function Decrypt(ByVal strDecoded_Pword As String) As String
        On Error Resume Next
        Dim i, ct As Integer
        Dim letter, dec, StrValappend, strVal As String
        dec = ""
        strDecoded_Pword = StrReverse(strDecoded_Pword)

        For ct = 1 To Len(strDecoded_Pword) Step 2
            StrValappend = Chr(Val("&H" & (Mid(strDecoded_Pword, ct, 2))))
            strVal = strVal & StrValappend
        Next
        strDecoded_Pword = strVal

        For i = 1 To Len(strDecoded_Pword)
            letter = Mid(strDecoded_Pword, i, 1)
            dec = dec & Chr(Asc(letter) - i - 5)
        Next
        Decrypt = dec
    End Function

尝试Eval而不是Bind:

<%# Decrypt(Eval("passwordID")) %>
