DataSource Controls :: Script To Clean Up HTML Text?

Jun 10, 2010

I got a column which contains html content. The problem is, the content is not properly formatted. Meaning they consist of a big bulk of text, but without <p> or line break or proper <li>. Can anyone think of a quick way to write a script to tidy it up? I can't go through each and edit as there are like five thousands rows of them...

AJAX :: HTMLeditor, Always Paste With Word Clean Up On?

Oct 11, 2010

I haven't been able to find a post about this, but the HTMLEditor is finally a rich text editor that properly removes word formatting without messaging up other stuff (thank god!). However, because I know my users, I would like for this 'paste as word' mode to be always on whenever they paste, how can I accomplish this?

AJAX :: Data Driven Site - Clean Page Load?

Jul 2, 2010

I have a data driven site that displays a lot of information, particularly images, using listviews contained within UpdatePanels, since this data can change with each post back you often see 'submit query' before the Item image appears. So, is there a way of making the page display only after it has finished loading data? The delay as the page loads is only brief but looks quite ugly when 'Submit query' appears all over the site.

Setting Request.ContentEncoding / The Text Gets All Messed Up When The User Enters Data?

Jan 20, 2011

I have a page that supports multiple languages (the user can change the language at any time).I update the thread's culture based on the user selection in the Initialize Culture method.

I also update the response object based on the code page for the selected country and set its charset to the WebName of the encoding used (if i don't update the response object based on the code page, then the data bound to controls gets garbled). the resource files are also localized based on the code page.

After doing the above changes, the page is getting displayed correctly in the browser.

However, when the user enters data in one of the Asian languages, the text gets all messed up. The drop down list actually throws the invalid callback or postback argument exception.

On checking the request.contentEncoding i found that it was still UTF-8 (set in web.config).

If I change the request.ContentEncoding during BeginRequest event, the input comes in correctly. But I am not sure of the user selected language this early in the page cycle.

I'm considering to host WCF Rest Service that i've built on IIS 7. The URL to access my service will be something like

Recently, i've been looking to some REST API implementation with a clean URL like Yahoo API

I'm wondering what will be the best WCF host environment (e.g. Windows Service) or any solution (e.g. URL rewrite module) considering that I dont want to have application name and .svc in my URL so that I can have a completely clean URL for my REST API

C# - Characters To Strip Out In A SEO Clean Uri?

Jan 19, 2010

I'm using asp.net/C# and I'm looking to create unique(?) uris for a small CMS system I am creating.

I am generating the uri segment from my articles title, so for example if the title is "My amazing article" the uri would be www.website.com/news/my-amazing-article

There are two parts to this. Firstly, which characters do you think I need to strip out? I am replacing spaces with "-" and I think I should strip out the "/" character too. Can you think of any more that might cause problems? "?" perhaps? Should I remove all non-alpha characters?

Second question, above I mentioned the uris MAY need to be unique. I was going to check the uri list before adding to ensure uniqueness, however I see stack overflow uses a number plus a uri. This I assume allows titles to be duplicated?

C# - Clean User HTML In .net?

Jan 6, 2010

My C# site allows users to submit HTML to be displayed on the site. I would like to limit the tags and attributes allowed for the HTML, but am unable to figure out how to do this in .net.

I've tried using Html Agility Pack, but I don't see how to modify the HTML, I can see how to go through the HTML and find certain data, but actually generating an output file is baffling me.

Does anyone have a good example for cleaning up HTML in .net? The agility pack might be the answer, but the documentation is lacking.

.net 4.0 - Clean Web.Config File?

May 9, 2010

I am wondering having clear web.config file could be good but you know some shared web hosting companies don't allow us to touch things like machine.config and etc.

So If a lot of things have been moved onto machine.config, then will we be allowed to change things like we used to through web.config file.

C# - Clean Up The Surface On WaterMark Of An Image?

Aug 11, 2010

There is an image for the surface, and a text is written on the image for 184 rows of date..
Thus, it is expected to see 184 different text written image files are generated with all the same background images. (The code is declared below...)

The problem is that the first text is written for all 184 different data.. I think I have to remove something in the loop. But what is that ??

Clean Way To Output Values In MVC Views When Value Is Not Null?

May 21, 2010

Is there a better way to write the code below? I have quite a few blocks that are similar, and this is making the code in the Viewpage very messy to work with. The data value with the associated label only needs to be output when certain conditions are met, which is almost always if the value is not null. The options I can think is to use a response.write to atleast minimize the usage of the ASP script tags, or to format the webpage is such a way that the label displays with an appropriate n/a type value.

<% if (myData.Balance != null)
{ %>
Balance: <%= String.Format("{0:C}", (myData.Balance))%>
<% } %>

C# - LinkButton Passing Multivalue Possible Clean Solutions

Dec 9, 2010

I once asked for a way to let a linkbutton pass more than one value in the commandArgument and then I reached the approach where I pass a string of multiple values separated by any character and split it into it's original parts...that didn't work out I don't know what was wrong with the splitting!

Now I tried the only solution I got, which is created a user control of the LinkButton and add properties to accept any values nedeed!...could you please tell me what's wrong with my 2 approaches and which is better ?

The first question can be found here : link text

and this is the code for the user control approach >>

MultivaluedLinkButton.ascx :
<asp:LinkButton ID="LnkBtnSort" runat="server" Text="Sort" OnClick="LnkBtnSort_Clicked"/>
MultivaluedLinkButton.ascx.cs :
public partial class MultivaluedLinkButton : System.Web.UI.UserControl
{
public event EventHandler Click;
private int _sortingType;
private string _sortingFactor;
private string _text;
public int SortingType
{
set { _sortingType = value; }
get { return _sortingType; }
}
public string SortingFactor
{
set { _sortingFactor = value; }
get { return _sortingFactor.ToString(); }
}
//public string Text
//{
// set { _text = value; }
// get { return _text.ToString(); }
//}
protected void LnkBtnSort_Clicked(object sender, EventArgs e)
{
if( Click != null )
{
this.Click(this, EventArgs.Empty);
}
}
}
Finally, Here's the implementation of my control inside an aspx page:
protected void MultivaluedLinkButton1_Clicked(object sender, EventArgs e)
{
MultivaluedLinkButton ctrl = (MultivaluedLinkButton)sender;
using (SqlConnection cn1 = new SqlConnection(ConfigurationManager.ConnectionStrings["testConnectionString"].ConnectionString))
{
using (SqlCommand cm1 = new SqlCommand(commandString2, cn1))
{
cm1.Parameters.Add("@arrange_by_id", System.Data.SqlDbType.Int);
cm1.Parameters["@arrange_by_id"].Value = ctrl.SortingType;
cn1.Open();
using (SqlDataReader dr1 = cm1.ExecuteReader())
{
SortBy_rpt.DataSource = dr1;
SortBy_rpt.DataBind();
}
}
}
}

The item template of the repeater in the implementation page :

<ItemTemplate>
<uc1:MultivaluedLinkButton ID="MultivaluedLinkButton1" runat="server" OnClick="MultivaluedLinkButton1_Clicked" SortingType='<%#Eval("arrange_by_id")%>' />
</ItemTemplate>

MVC :: Clean Way Chain Html Attributes In View?

Mar 11, 2010

I would like to add html attributes to form inputs, specifically disabled="disabled" in addition to others. I have conditional logic in the Controller that determines whether to add this html attribute or not that sets a bool IsDisabled flag in my ViewModel e.g.

class ViewModel
{
bool IsDisabled {get;set;}
}

So in my View, I want to do something like:

<%= Html.TextBoxFor(x => x.Data, new {maxlength = 30, IsDisabled ? disabled = "disabled": null}) %>

or rather something like

<%= Html.TextBoxFor(x => x.Data, new Dictionary<string, object>().Add("maxlength", "30").AddConditional("disabled", "disabled", IsDisabled) %>

Except that Add returns void, and there is no such thing as AddConditional. Is there something like an MVC HtmlAttributeBuilder class, or should I just extend Dictionary with these two extension methods?

Can Find A Clean API For Visual Basic Development

Feb 18, 2010

I am completely new to ASP.NET programming, and was asked to work on a small project involving ASP.NET, VB (which I am new to as well) and Microsoft SQL Server 2005.

Being used to php/java I was hoping to find some kind of similar API to php.net and the javadoc. It would be very useful to have as I would prefer to work with a text editor, instead of using DreamWeaver or Visual Web Developer.

In the project I basically only need to use ASP.NET to read from a SQL 2005 database and write to JSON files.

Mobiles :: Clean Exit From Mobile Website?

Nov 4, 2010

I've just completed my first iPhone-compatible & Droid-compatible mobile app. At one time, I was confounded by differences in back button behaviour between the two platforms, but I came up with a suitable workaround.One thing remains that I'd like to correct if it's at all possible. The application is very session-variable dependent, so naturally, its very dependent on sessions. Users invariably use leave pages open when they turn off their smartphones, and this means that they return to a non-repsonsive timed-out page when they turn it back on. Can anything be done to preclude this? As in active web app or no web app?

AJAX :: Show/hide The Text Box Depending On The Text Of The Selected Item In The Combo Box?

Nov 13, 2010

I have a .net 3.5 web form with an ajax combo box and a text box inside it. The bombo box is bound to a SqlDataSource.

My requirement is to show/hide the text box depending on the text of the selected item in the combo box. If a particular string, say 'xyz', appears in the text of the selected item, the I will make the text box invisible. I enabled the AutoPostback, made the text box disappear in the SelectedIndexChanged event, and everything worked fine.

However, when users enter their own texts (which are not in the list items), I am unable to show / hide the text box. I've tried the TextChanged event but nothing happens. It seems the event is not trigger after I enter a new text and locate the focus to other place.

is there a way to prevent the user ented text from being inserted into the bombo box?

AJAX :: Text In Tabpanel Not Shown But Text Is Rendered To Browser

Apr 30, 2010

I have placed the code below on a page. The strange thing is that the "SOME TEXT" string doesnt show up in the page! I do see "upanel" and "pnl":

upanel
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
pnl
<cc1:TabContainer OnActiveTabChanged="TabChanged" ID="tabContainer" runat="server"
ActiveTabIndex="0" OnClientActiveTabChanged="ActiveTabChanged" Width="100%">
<cc1:TabPanel ID="tp1" runat="server" HeaderText="A tab">
<ContentTemplate>
<asp:UpdatePanel ID="UpdatePanel3" runat="server" UpdateMode="Always">
<ContentTemplate>
SOME TEXT
</ContentTemplate>
</asp:UpdatePanel>
</ContentTemplate>
</cc1:TabPanel>
</cc1:TabContainer>
</ContentTemplate>
</asp:UpdatePanel>

HOWEVER, when I view the pagesource, I see this, so the text IS rendered to the browser! What can be happening here?

upanel
<div id="ctl00_CPHCenter_UpdatePanel2">
pnl
<div id="ctl00_CPHCenter_tabContainer" style="width:100%;visibility:hidden;">
<div id="ctl00_CPHCenter_tabContainer_header">

Generating Clean Markup With Literal And String.Format

Jun 2, 2010

In order to generate clean markup, I often resort to using code similar to this:

<asp:Literal ID="ltItem" runat="server">
<li class="{0}"><a href="{1}">{2}</a></li></asp:Literal>

And in the codebehind:

[code]....

Therefore my question:

Is this a common way to generate clean markup? Are there better alternatives? Is the databinding syntax approach preferable?

Best Practice For Making Links That Take Advantage Of Clean Urls

I'm using ASP.NET 4 and the routing engine. In my Global.asax I have something like this.

routes.MapPageRoute(

"manager/items",
"~/Manager/Item/Items.aspx"

Is writing a link this this acceptable?: <a href="/Manager/Items"></a> Should I be using the <% %> tags and code within to retrieve the route name, "Items" in this case?
