Suggestions for an effective approach to use for designing a form

groverg — Thu, 19 Nov 2009 21:30:00 GMT

Hi,

I need to develop a form which has to be used by various markets around the globe. The form has a couple of text boxes for input and just a button for submitting it.

The tricky part is, based on each market, some of the text boxes are different, also, the layout of these text boxes changes based on the market for ex US might have a first name, last name text box while Taiwan could just have a single textbox called name. Another interesting thing is the rules that are attached to the input boxes, say if there is a textbox for phone, it might accept numbers in a different way for different countries, in short, there are rules associated for each country.

As i mentioned above, the layout becomes most critical in the address section as different countries have different ways how people enter addresses, basically the form elemensta re the same but their positioning changes.

I wanted to check what could be some good ways for approaching this problem?

How can I convert GetPostBackEventReference to ClientScript.GetPostBackEventReference

How can I convert GetPostBackEventReference to ClientScript.GetPostBackEventReference?

My code is recommending that I do this. When I try I get a message that clientscript is not a member of control.

Public Shared Function DisableTheButton(ByVal pge As Control, ByVal btn As Control) As String
        Dim sb As New System.Text.StringBuilder()
        sb.Append("if (typeof(Page_ClientValidate) == 'function') {")
        sb.Append("if (Page_ClientValidate() == false) { return false; }} ")
        'sb.Append("if (confirm('Are you sure to proceed?') == false) { return false; } ")
        sb.Append("this.value = 'Please wait...';")
        sb.Append("this.disabled = true;")
        sb.Append(pge.Page.GetPostBackEventReference(btn))
        sb.Append(";")
        Return sb.ToString()
End Function

Reducing size of ASP.NET pages

ajay.ms2000 — Sat, 21 Nov 2009 19:52:39 GMT

We all know when a page is requested, ASP.NET process the page, its server controls and finally sends the Html to the client side for the browser to render it. The time taken to download the html to client side depends mainly on its final size. If your page is data rich, it would take much time to fetch it. So here I am presenting a technique to reduce the sizes of the pages.

When you see the pages html source by clicking the “View Source” in the browser, you could see that there are a lot of white spaces on the left side of each line on the html. This is actually a waste. Try saving the html page to your desktop and notice its size. Then delete all the spaces on the left side and then watch its size. You could see that the size of the page reduces considerably, sometimes more than 50%!! (watch the view source of Orkut in the browser).

Here is a technique to achieve the same.

1. Create a class in the App_Code, that is deriving from “System.Web.UI.Page” class.

public class MyPageBase : System.Web.UI.Page
{
}

2. Replace “System.Web.UI.Page” from all your web pages (.aspx.cs) and put MyPageBase. Means now all your webpages are deriving from MyPageBase.

3. Override the Render function in this class

public class MyPageBase : System.Web.UI.Page
{
    protected override void Render(HtmlTextWriter writer)
    {
    }
}

4. Place the below code inside the function and also write a support function as below

public class MyPageBase : System.Web.UI.Page
{
    protected override void Render(HtmlTextWriter writer)
    {
            base.Render(htmlwriter);
            string html = htmlwriter.InnerWriter.ToString().Trim();

            if (ConfigurationManager.AppSettings["OptimizeHtmlOutput"] != "0")
            {
                bool isAsync = !html.StartsWith("<");

                if (!isAsync)
                {
                    StringBuilder sb = MyPageBase._TrimHtml(html);
                    writer.Write(sb.ToString());
                }
                else
                {
                    StringBuilder sb = new StringBuilder();

                    int startIx = 0;
                    while (true)
                    {
                        int x = html.IndexOf("|updatePanel|", startIx);

                        if (x > -1)
                        {
                            int xS = html.LastIndexOf("\r\n", x); xS = (xS < 0 ? 0 : xS);
                            int xE = html.IndexOf("\r\n", x) + 2;

                            string header = html.Substring(xS, xE - xS);
                            header = header.Trim().TrimStart('|', ' ');

                            string sLen = header.Substring(0, header.IndexOf('|'));
                            int cLen = int.Parse(sLen);

                            string content = html.Substring(xE - 2, cLen);
                            content = MyPageBase._TrimHtml(content).ToString().Trim();

                            startIx = xE - 2 + cLen;

                            cLen = content.Length + 4;
                            header = (xS > 0 ? "|" : string.Empty) + cLen.ToString() + header.Substring(header.IndexOf('|'));

                            sb.AppendLine(header);
                            sb.AppendLine(content);
                        }
                        else
                        {
                            string stateData = html.Substring(startIx);
                            sb.Append(stateData.Trim());

                            writer.Write(sb.ToString());
                            break;
                        }
                    }
                }
            }
            else
            {
                writer.Write(html);
            }
        }
    }

    private static StringBuilder _TrimHtml(string source)
    {
        StringBuilder sb = new StringBuilder();

        source = source.Trim();
        using (StringReader sr = new StringReader(source))
        {
            string data = string.Empty;
            while (data != null)
            {
                data = sr.ReadLine();
                if (data != null)
                {
                    data = data.TrimStart(' ', '\t');
                    if (data != string.Empty) sb.AppendLine(data);
                }
            }
        }

        return sb;
    }
}

Notes:
1. Notice the usage of ConfigurationManager.AppSettings["OptimizeHtmlOutput"] != "0". You can define a key in app settings section of the web.config file to enable or disable this feature. Any value other that “0” will enable the optimization.
2. This code works well in AJAX based applications as well.

Compare the size difference and performance by changing the flag. This is very beneficial especially in pages which contains a huge amount of data.

validator Control Problem

new.preetam — Sat, 21 Nov 2009 19:52:07 GMT

Hi,

I have a simple page. Where suppose there is a Textbox, Submit button, Cancel button and sime other links on Master page to navigate to other pages. Now I do have a required field validator control, which is targetting the text box using it's ControltoValidate property. Now as per my requirement if I dont put any value into the text box and click on Submit button then it shoud display default preset error message, but if I click on cancel button then it should redirect to other page. Now, the problem is, if I click on any link, or if I click on cancel buton without providing the input inside the text box, then I am not being able to redirected to other page. What shall I do?

Should I use the validation group for this purpose, which should be specified for the validator control and for the submit button only?

Can any one answer?

C# How to deploy a User Control in a Website?

iturune — Sat, 21 Nov 2009 12:14:13 GMT

I have made a User Control called AccountInfo, when I drag it on my Default.aspx page, it gets a green line underneath and I can't access in Default.aspx.cs. I am presented with this error message:

"Element 'AccountInfo' is not a known element, this can occur if there is a compilation error in the web site, or the web.config is missing"

My 'AccountInfo' consist of various TextBoxes, DropDownLists, RadioButtonList, CheckBox placed in a Table.

The strange thing is that when I make a more simple User Control with just a couple of TextBoxes and drag it unto my Default.aspx page there is no problems, so why do the simple User Control work and my AccountInfo User Control not work?

I have uploaded a test project on skydrive: http://cid-67cedb7203d06459.skydrive.live.com/browse.aspx/.Public?uc=1

It's just a simple Website, with a simple User Control which works and then the User Control AccountInfo which does not work. Why do the User Control AccountInfo not work? Please have a look at the simple test project.

Below I have pasted the AccountInfo User Control:

Cache Expiration Problem in ASP .Net

shabeer50 — Thu, 19 Nov 2009 13:23:03 GMT

I want to cache table having more than 1 lakh records with more than 600 columns. At present i am caching the entire records in a single cache but it occupies nearly 0.5GB memory of my RAM. But the problem am facing is that i could not maintain the cache in the server for a period where i have set a absolute expiration of 10 hours, But the cache doesn't maintaini in the server for the mentioned expiration time.

I have seen one article which says the size limitation of a cache must be between 2-3GB.

Please suggest me

* What are the limitations in caching where in a huge data handling project?

*How can i play around with Cachies in terms of dependencies both hardware and software?

*What are the measurement criteria that needs to be taken care in Cache sizes and expiration policies?

Thanks in advance :)

elbasha — Sat, 21 Nov 2009 08:46:17 GMT

Hello,

I have redirect all site errors that occur to my page at ErrorPage.aspx, now my concern was to see if it is possible that whenever a user goes to that page (on form_load), I would get the URL he tried to go to, the error number, and the exception all listed in the form load for me to send an email to myself to note it.

            gvExcel.RenderControl(hw);
            StringReader sr = new StringReader(sw.ToString());

open a PDF file in App_Data from link created during Page_Load

dbijloos — Tue, 17 Nov 2009 11:48:43 GMT

Hi,

I know that this topic is not the first on this forum, but I cannot find one post that matches my specific case.

After the user logs in the application retreives the files for that user ID from the ASPNETDB in the App_Data folder. All files are placed as links in 2 tables based on their type (report/quotation). Now when I click a link, I it opens the error page with : Server Error in '/' Application. Illegal characters in path.

The path in the SQL database is "~/files/QuotationNOC091007.pdf" as a Varchar. I user this as the navigateUrl for the link. What did I do wrong?

How can I open the PDF file in Acrobat Reader?

Thanks in advance.
