Re: Converting aspx pages into ascx pages

9-Apr-14 14:08

Hi,

I have some aspx pages, as we are adding some new applications which are going to use some of the same pages we want to make those common pages as user controls.

I started making the aspx pages into User controls I changed the name of the files to ascx, ascx.cs, removed page attribute and put the control attribute, removed html, body and form tags from aspx file, in code behind I made change to inherit from UserControl class. Everything looks good upto this.

But those previous aspx pages were accessing some user controls, now those controls are displaying error message. Like at uc1:htmlhead and uc1:formheader it is displaying error message as "Unrecognized tag prefix or device filter uc1".

Below are the register and control directives for the user control. For the current User Control I have taken Control directive and for other ones I have taken Register directive. Am I missing any where. Please help me or suggest me or give me a link, any type of help is very helpful. Thanks in advance.

<%@ Register TagPrefix="uc1" TagName="HtmlHead" Src="../Includes/HtmlHead.ascx" %>
<%@  Page Language="c#" CodeBehind="ChangePass.ascx.cs" AutoEventWireup="false" Inherits="DIS.CnpWeb.Core.ChangePass" %>
<%@ Register TagPrefix="uc1" TagName="FormFooter" Src="../Includes/FormFooter.ascx" %>
<%@ Register TagPrefix="uc1" TagName="FormHeader" Src="../Includes/FormHeader.ascx" %>

<uc1:htmlhead id="HtmlHead1" runat="server"></uc1:htmlhead>
<uc1:formheader id="FormHeader1" runat="server"></uc1:formheader>

Looking at the ChangePass.ascx, it is a control so the following tag is incorrect:

HTML

<%@  Page Language="c#" CodeBehind="ChangePass.ascx.cs" AutoEventWireup="false" Inherits="DIS.CnpWeb.Core.ChangePass" %>

it should be:

ASP.NET

<%@ Control Language="c#" AutoEventWireup="false" CodeFile="ChangePass.ascx.cs"
    Inherits="DIS.CnpWeb.Core.ChangePass" %>

don't know if this will fix your error but this can be leading up to the issue.

Gridviews and hyperlinks help please

Hi, I have written a control that inherits from DataBoundControl

[ToolboxData("<{0}:MyClass runat=server></{0}:MyClass>")]
[Designer(typeof(MyClassDesigner))]
[ToolboxItem(true)]
public class MyClass: DataBoundControl

Problem is, when I try to drag it from the toolbox to the page, the mouse cursor changes to an icon that represents it's not allowed(circle with diagonal line through it). How do I make my control support that? The control works just fine if I manually type it in the page.
What am I forgetting? Any ideas?

web api query - 401 error

Dear all,

When I call 'api/values', it only allows me login as 'full' user details, but if a login as 'trial' user login details, it throws a 401 error. I would like to ask, if I am missing something in the queries in the user class below or the basicAuthn class:

protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
     {
         AuthenticationHeaderValue authValue = request.Headers.Authorization;

         if (authValue == null || authValue.Scheme != BasicAuthResponseHeaderValue)
         {
             return Unauthorized(request);
         }

         string[] credentials = Encoding.ASCII.GetString(Convert.FromBase64String(authValue.Parameter)).Split(new[] { ':' });
         if (credentials.Length != 2 || string.IsNullOrEmpty(credentials[0]) || string.IsNullOrEmpty(credentials[1]))
         {
             //return Unauthorized(request);
             var resp = new HttpResponseMessage(HttpStatusCode.NotFound)
             {
                 Content = new StringContent(string.Format("access denied")),
             };
         }

         ClaimRole user = repository.trial(credentials[0], credentials[1]);
         ClaimRole user2 = repository.unlim(credentials[0], credentials[1]);

             if (user == null || user2  == null)
         {
             var resp = new HttpResponseMessage(HttpStatusCode.NotFound)
             {
                 Content = new StringContent(string.Format("access denied")),
             };

         }
         else
         {

            IPrincipal principal = new GenericPrincipal(new GenericIdentity(user.Username, BasicAuthResponseHeaderValue), new string[] { user.role });
             Thread.CurrentPrincipal = principal;
             HttpContext.Current.User = principal;
         }

         return base.SendAsync(request, cancellationToken);

     }

User Class

public ClaimRole trial(string username, string password)
     {
         var query = (from s in db.subs
                     join u in db.user on s.sUID equals u.uID
                     where s.sExpiryDate >= DateTime.Now &&
                     u.uUsername == username &&
                     u.uPassword == password
                     select u).FirstOrDefault();

         if (query != null)
         {
             // Build a user and add the appropriate Trial role
             return new ClaimRole { Username = query.uUsername, Password = query.uPassword, role = "Trial" };
         }
         else
         {
             // No user was found
             return null;
         }
     }

     public ClaimRole full(string username, string password)
     {
         var query = (from s in db.subs
                     join u in db.user on s.sUID equals u.uID
                     where s.sPID.Value == 163 &&
                     u.uUsername == username &&
                     u.uPassword == password
                     select u).FirstOrDefault();

         if (query != null)
         {
             // Build a user and add the appropriate Trial role
             return new ClaimRole { Username = query.uUsername, Password = query.uPassword, role = "full" };
         }
         else
         {
             // No user was found
             return null;
         }
     }

Please advise
many thanks

I guess the problem is here:

ClaimRole user = repository.trial(credentials[0], credentials[1]);
ClaimRole user2 = repository.unlim(credentials[0], credentials[1]);
if (user == null || user2  == null)

If the user does not have BOTH the trial and unlim priviledges, you send the Access Denied message.
Use && isntead of ||.

Thank you so much for your response and help. I am sorry to inform, that i have tried using the '&&' operator but I am still getting the same 401 error, when logging in using full query user details.

i would like to ask, if their is certain parameter and method, i should be looking into while debugging the code.

I really appreciated your help. please advise.
Many thanks.

then test those two repository.trail / repository.unlim functions. At least one of them has a bug.

How to save secured password for individual users

Thank you for your feedback. i am stuck on little status code issue, regarding this long problem. When I debug the full and trial repository, while login as 'trail' user, 'resp' variable below is highlighted as red with a 404 status code, but on the fiddler testing environment, it displays the url as 401 unauthorized issue.

 ClaimRole user = repository.trial(credentials[0], credentials[1]);
ClaimRole user2 = repository.full(credentials[0], credentials[1]);

     if (user == null || user2  == null)
 {
     var resp = new HttpResponseMessage(HttpStatusCode.NotFound)
     {
         Content = new StringContent(string.Format("access denied")),
     };

 }// this bracket is highlighted while debugging through which the local window shows 404 status code
 else
 {

<br />
resp --	{StatusCode: 404, ReasonPhrase: 'Not Found', Version: 1.1, Content: System.Net.Http.StringContent, Headers:

Hence I am little unclear, which error to look into. if you get time, could you please advice on any material i should look into or concentrate on.

Many thanks for your time and help.

As of now,Popup in a page asks for password and onclick jquery ajax method calls webmethod, which returns the actual password of the user for validation.

But if a press F12,the password gets viewed as response .

Note:- After buttonclick, page needs to redirect to the same page.

Never send a password back to the client. The program should send the user's input to the server side for validation. Not the other way round.

Apart from the fact that you shouldn't be sending the user's password to an unauthenticated client, you shouldn't be able to send the user's password, ever.

Passwords should NEVER be stored in plain text.

You should be storing a salted hash of the password. When you need to verify the entered password, you apply the same salting and hashing algorithm to the entered password, and compare the result to the stored salted hash of the real password.

See Salted Password Hashing - Doing it Right[^] for more information.

Exporting Repeater values in to Excel

Hi All,

I am trying to write repeater values in to Excel file, it is writing something but it not writing clearly. Can anybody please help where am I doing mistake. Another problem is repeater control has text boxes and td values. Initially I couldn't write into excel because of text boxes then I did this work around but didn't give me the solution I want.
Here is my code:

protected void ExportToExcel(object sender, EventArgs e)
{
     Response.Clear();
     Response.Buffer = true;
     Response.ContentType = "application/vnd.ms-excel";
    Response.ContentEncoding = System.Text.Encoding.UTF7;
     Response.AddHeader("Content-Disposition", "attachment;filename=" + ConfigurationManager.AppSettings["ExcelFilePath"].ToString() +
       ddlProductId.Text + "_" + ddlProcessor.Text + ".xls");
     Response.Charset = "";
     this.EnableViewState = false;

     System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
     System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

     HtmlForm frm = new HtmlForm();
     this.Page.Controls.Add(frm);
     frm.Attributes["runat"] = "server";
     frm.Controls.Add(this.rptMonthlyReport);
     frm.RenderControl(oHtmlTextWriter);
     rptMonthlyReport.RenderControl(oHtmlTextWriter);
     Response.Write(oStringWriter.ToString());
     Response.End();
}

public override void VerifyRenderingInServerForm(Control control)
{ /* Do nothing */ }

public override bool EnableEventValidation
{
    get { return false; }
    set { /* Do nothing */}
}

Then I have out put displayed as below. Please help me in this regard. Any help link or code snippet or a suggestion would help me a bit. Thanks in advance.

Hi,

Thank you for your help, it is working fine but the alignments are not that good. Like a column is taking lot of space but the other is not.
And I think it is taking Text boxes as it is in the excel file, is there any way to make everything as normal text and write those values in to excel file as just normal text.

Thanks & Regards,

Do you have text-boxes in repeater? while exporting data to excel i think there should textbox instead of that labels or Literals should be there,

indian1439-Apr-14 7:33

9-Apr-14 7:33

Yes I do have text box, they are editable text boxes. This client made me to create almost an online excel sheet man Smile | :)

. Sorry I was kidding. But yes it has text boxes. And I can't get rid of them too because user will be entering values in Text boxes, then it is going to change the totals.

The problem with it is, it is always displaying a message and then in excel it is showing the text boxes as it is.

Is there any way to get rid of it? and make it as a plain excel.

Thanks & Regards,

Your repeater is always in edit mode...? Strange.
generally what happene. we display data in labels or literals and when we need to edit some record just click on edit button and it become editable.
Simple approach, in this way your export to excel will work absolutely fine.
