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?
Is it possible to use a custom format string in the markup? In the codebehind page the string looks like this:
MyBoundField.DataFormatString = "{0:n" + MyEnvironment.CurrentCulture.NumberFormat.CurrencyDecimalDigits + "}";
i.e i want to do something like the below example (but that does not work)
<
asp:BoundField
DataField="Amount"
DataFormatString="{0:n'<%# SummarumEnvironment.CurrentCulture.NumberFormat.CurrencyDecimalDigits.ToString())
%>'"
/>
I am fetching some data from Db and displaying it in a textarea using jquery in the following way.$('#textareatest').val('<% =teststring %>').It is possible that the string 'teststring' can contain XHTML line breaks(<br/>).whenever the string contains <br/> I am getting the 'unterminated string literal' error.I saw a number of posts considering '' as line breaks and suggesting to escape it.I tried to escape the <br/> similarly,but it didn't work.
View 4 RepliesWhat I'm trying to do is take an instance of a control, and figure out what the markup would look like based on the property values set in the code behind. We've built a web-based web form designer. At the end of the design process we save the markup. For simple controls with supported types, generating the markup was easy. For complex controls with nested properties or unsupported types, we're faced with creating a custom markup generator for each custom control. I was hoping to find info out there that would jump start this development effort.
In simple terms, I have this:
Dim Ctl as Control = CType(Asm.CreateInstance("MyNameSpace.MyControl"), Control)
Ctl.Name = "Name of my control"
And I want to end up with this:
<cc1:MyControl ID="MyControl1" runat="server" Name="Name of my control" />
As it stands right now, I have a literal control on my page. In my code-behind, I'm using StringBuilder to generate some JavaScript. Also on that page I have a item collection. What I want to do is for each item in my item collection, generate my literal which will in essence generate my JavaScript. Here is an example of my code-behind now. I'm ok with doing something different, but I just need to generate said JavaScript for every item in the collection and I'm not sure how to do it.
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("<script type='text/javascript'>");
sb.Append("mboxCreate("product_productpage_rec",");
sb.Append(""entity.id=" + _prodID + "",");
sb.Append(""entity.categoryId=" + _categoryID + "",");
sb.Append(""entity.name=" + _prod.Title + "",");
sb.Append(""entity.pageURL=" + Request.Url.ToString() + "",");
//The following value has been taken from the productImageControl code behind.
//Might have to refactor in future as a property of the image control.
string filename = AppSettingsManager.Current.ProductImagePathLarge + _prod.ActiveProductItemCollection[0].Sku + AppSettingsManager.Current.ProductImageExtension;
sb.Append(""entity.thumbnailURL=" + filename + "",");
sb.Append(""entity.inventory=" + _prod.ActiveProductItemCollection.Count + "",");
sb.Append(""entity.value=" + _prod.ActiveProductItemCollection[0].ActualPrice + "",");
sb.Append(""entity.ProductItemID=" + prodItem.Id + "",");
sb.Append(""entity.addToCartImg=~/Images/Buttons/btn_AddToCartFlat.gif");<");
//The last line has to be /script. < inserted on prev line. do not change it or bad things will happen.
sb.Append("/script>");
//add script to page
this.LiteralMBoxScript.Text = sb.ToString();
I am trying to display an error to the user of a web page using a javascript alert popup, I currently have the following code to clean the error string:
errorMessage.Replace("'", "'")
But this is not sufficient as some illegal characters are not being removed, is there a static method somewhere in the framework that will format my string for clean insertion into html?Update: my initial question was slightly ambiguous. the string needs to be valid as in alert('this is some 'illegal text' that will not popup');I will try Server.HtmlEncode, hopefully it will do the trick.
I'm bulding document-from-template engine. At certain points I need to match on Reg Exp groups and replace template text with content from a db.
I 'hardcoded' my RegExp initially, doing something like: Regex r = new Regex(@"{DocSectionToggle::(?<ColumnName>w+)::(?<ResponseValue>.+)}[[(?<SectionContent>.+)]]", RegexOptions.Multiline);
it does group capture, so the syntax isn't the prettiest.
Just to make things neater and because I want' to keep the patterns in web.config or elsewhere, I've 'evolved' algorithm to something like:
[code]...
But I'm getting an error: 'Input string was not in correct format'.
Is this a limitation of string.Format(...)?
I have a decimal value that is a winning percentage so will always be three digits to the right of the decimal but I dont want the 0 appearing to the left of the decimal.What format string can I use to clean it up?
I want .667
im getting 0.667
Can someone please tell me the difference and the advantages in these other than styling them? ```First option:
[Code]....

I'm trying to pass a string value to a javascript function from a LinkButton's OnClientClick event, but the function is receiving "<%# Container.DataItem %>" instead of the value. Here's the code:
OnClientClick="javascript:SaveQuotaGroupCode('<%# Container.DataItem %>');"
The container is a collection of strings. Why is it not evaluating?EDIT: This is located in a nested ListView. The datasource for the inner ListView is a property in the datasource of the outer ListView.
Here is my JavaScript:

function onholdev(index) {

We have a service that generates a report (using word templates and a 3rd party library), and then returns a string in HTML. While this HTML isn't great - its formatted correctly in this string. We want this HTML to show up on a page - format intact. What we currently have done is set an ASP.net Literal's text element to this string. While this works, I have noticed that it has reformatted the HTML string slightly. For the most part, it looks like it generated a bunch of new CSS classes, and a new style element in the HTML. This HTML does not exist in the string thats being returned. I could filter all of this back out, but wonder if there is a better way. I assume that the Page itself is altering something. What is the best way to display this raw HTML back to the user? I can't directly use a Response.Write(string), because this page does have a few other controls on it.

I have a simple function that is supposed to create a string of year values(separated by a comma) from a form that contains checkboxes for a set of years.
[Code]....
The problem is, it is doubling data somehow. For example, if I check the checkboxes for 2008, 2009, 2010, it will return :
,2010,2010,2009,2010,2009,2008
But I can't figure out why it is doing this...is there something I am doing wrong?
I created a UserControl and added a public DateTime property. I want to set this property in Markup (ie. <cc1:MyControl runat="server" id="MyControl1" DateTimeProp="1/1/2010" /> ) however I live in a place with a dd/mm/yyyy date format so it complains if I set something like "20/1/2010". Is there a way to set markup in my local datetime format or do I have to conform to "mm/dd/yyyy"?

queryBuilder = queryBuilder.Substring(0, queryBuilder.Length - 1);

I have project in development where string operations like "Hi " + variable + ", welcome to Project" are used at many places (given example is very minor one).
One of the requirement is to convert it to string.format style.
It is very long and tedious job, where I would not like to break earlier working code due to any human error might happen while converting it.
I would like to if any Macro or VS command which I can create to handle it. Just like we mark block of code and do Extract function in Re-factor options.

I've just encountered an interesting problem in a standard BoundField in a GridView. The field is for EmployeeCode, which is purely numeric, but stored in a character column in the database. The DataFormatString="{0:00000}" attribute on the BoundField doesn't work, as I assume that format is only for numeric values.
To work around this, I had to use a TemplateField, and bind the text value using the attribute Text='<%# PadNumericString(Eval("EmployeeCode").ToString(), 5) %>'. Is there no simpler way of doing this?
