Can you use FluentHTML or other alternatives in an web application user control?
Can you put a markup file in a System.Web.UI.Control like the System.Web.UI.UserControl but without the burden of the Page object?
I would like to reduce the number of lines of the following code:
[code]....
is it possible to get HtmlTextWriter of a control?
if no, then how can i call the RenderEndTag of a control in code behind?
i am facing a problem in my application. i extended the listbox user control and override its RenderEndTag event.
if i used the new listbox (Mylistbox) normally inside a WebPage, everything works fine. but when i put Mylistbox in a Webusercontrol and include the Webusercontrol in a WebPage, the RenderEndTag of the control is not called for some reason.
If I have an HtmlTextWriter with some content in it, is it possible to append the output of ontrol.RenderControl to the existing content of the HtmlTextWriter directly?
Or do I always have to output to a separate HtmlTextWriter/StringWriter/StringBuilder and then append the StringBuilder?
We're using the MS Chart for .net, but encountering the "image not found" problem for which there doesn't seem to be a solution. Are there any alternatives for generating simple charts?
View 4 RepliesCurrently, I'm using a Table control and manually retrieve data from the database and then dynamically create the Table to display the data. However, I find Table control hard to format/style. GridView looks easier because we have a skin created for gridview which will give a uniform look. But the problem is GridView is designed to work with Data components instead of manually data retrieval.
View 1 RepliesI've got an ASP.NET 3.5 Web Forms application in which a large chunk of code needs to be duplicated between a few different pages. Sounds like the ideal candidate for a user-control right? Problem is, this cannot be contained within a <form runat="server"> because it contains a client-side form of it's own. There are no runat=server controls or postbacks or anything that really need that webform - think of it just as a chunk of HTML with a few basic <% %> tags. I'd just want to set a property on the control when it's loaded, so that it knows what to output. This is purely an exercise to make the code easier to maintain.Before I resort to using an oldskool <!--#include-->, is there some better way of doing this?
View 5 RepliesI have a modal pop extender that has a user control in it, I use it in several forms in a ASP.NET 4.0 project. I am not very happy with the js code that it produces and the mess in the markup So, any worthy alternatives that can be controlled from the codebehind easily :)?
View 2 Replies I have this code that creates a document, and want to show it in a new page. I'm new with the HtmlTextWriter class, and don't know how to accomplish this.

Quite simply I want to be able to test that a Asp.Net web forms server control is outputting the correct Html as it will be building dynamic content. I'm just starting to create the control and wanted to do it in a TDD style building up the Html that gets output. I've created a separate class to do the actual Html building so that I am able to test it in isolation outside of the normal Asp.Net pipeline.In my unit tests I can control what html is returned but I'm having problems confirming that the html contains the markup I am expecting for example:
<div id="wrapper">
<div id="fields">
</div>

I am using the AttributeCollection with the HtmlTextWriter objects and want to set the ReadOnly attribute.
It seems everything needs to be setup Attribute="value" but the readonly property just needs the name not ReadOnly=True.
Is there a way to just output ReadOnly with the AttributeCollection instead of ReadOnly=True?
You may be asking why, I don't know how compatible ReadOnly=True would be with older browsers and everything I design is compatible with ie4+.
I have a third party tool that creates an img tag through code using HtmlTextWriter's RenderBeginTag, RenderEndTag & AddAttribute methods. I want to get the resulting HTML into a string.
I tried the reflection method mentioned here but I get a error "Unable to cast object of type 'System.Web.HttpWriter' to type 'System.IO.StringWriter". The InnerWriter type of the HtmlTextWriter is of type HttpWriter.
how to copy the output HTML into a string?

I am creating a custom server control in which I place a RequiredFieldValidator. In the the Render method and I want to dynamically create a RequiredFieldValidator and render it to the HtmlTextWriter.
The problem is, when I call RenderControl on the RequiredFieldValidator, it only generates a span for me with no javascript or client side code.
How can I completely render a RequiredFieldValidator to an HtmlTextWriter?
Im looking for some input on a validation problem i have. My demands for validation are:
1. Able to do database checks
2. Error messages are custom and imported from other localized source as stringvariables(NOT resource files).
3. DRY serverside and clientside validation.
As far as ive seen data annotations dont work well under these cirumstances, custom attributes are needed just to be able to output the strings(wonder why this wasnt thought of). This isnt a dealbreaker but as ive tested sofar custom attributes must be added in the global.asax wich i 1. cannot get to work in the CMS im building this on and 2. i dont want to have to edit the global.asax everytime the scripts are implemented. Serverside this solution works fine though. From what ive read IDataErrorInfo should not be used? So havent really checked how to get this rolling with client-side either.
My thought was using custom service layer validation with xval but documentation is very poor to the extent i could find any(couldnt find any real nfo on how to implement xval with your own code, ie not using the autgened client-side metadata wich leads to the annotation problem described above). So i have a hard time finding any working solution other than to build something 100% custom.
Do anyone have a solution or perhaps some information or can steer me in any direction on the best way to getting this done in a good fashion other than building custom?
I'm considering purchasing a resharper license but would like to know if there are any possible alternatives to resharper and how would you rate these compared to reharper? It doesn't necessarily have to be a free alternative but I would just like to know how good equivalent products are.
View 8 RepliesI am looking for an alternative to using UDP multicast on the .NET Framework and am looking for suggestions.I need to send messages to several web servers running quite a few ASP.NET applications. These messages would be one-way only, coming from several different machines. UDP multicast would be perfect except that I can't use it due to it requiring administrative rights. Seehttp://stackoverflow.com/questions/1941463/asp-net-multicast-udpclient-problems for details as to why.Is there something else that would work in a similar manner, allowing multiple applications to receive broadcast-type messages?

What is your opinion of DataSets vs. just stubbing out custom classes and working with those? What are other alternatives?
I'm developing an ASP.NET website that will allow users to view and print Microsoft PowerPoint slides. Right away, I knew that Aspose had a product that would likely allow me to do this. What I'd like to do is look at alternatives just to say to management, "Yes, I've looked at the alternatives and they are". I can't seem to find any other than the open source project on Source Forge which seems to be mostly dead and I'm not even sure if it's something that would meet my needs anyway: [URL]. Is anyone aware of any alternatives to Aspose Slides .NET? Please list them if so. If you are aware there are no decent alternatives, I would find that information useful as well.
View 2 RepliesIn my web application, I have a dynamic query that returns huge data to datatable and this query is often recalled with different parameters. So database is exhausted. I want to get all record with no parameters to an object, and perform queries (may be with linq) on this object. So database will not be exhausted. Which objects can be used instead of datatable?
View 1 RepliesAre there any other ViewState alternatives? I've heard a lot Like Session, holding the state of some of the page's controls' state and getting destroyed the moment the user leaves the page. I know I'm describing ViewState itself, but I'm looking for a pattern of sorts or suggestions so I can avoid ViewState altogether. An example of how I'm using it is where I'm storing the contents of my grid (A list of ViewModels) to ViewState. This helps to know which entries are dirty, which ones have been modified, their indexes, the currently selected objects, etc.
View 4 Repliestitle isn't as detailed as I hoped but I have a few questions. Traditionally I've always been a mixed mode person, storing PDFs and other things into the file system with pointers from my SQL DB to them.
Recently I've heard more people storing files into the DB directly and wonder if I'm storing files around 100-200MB in size, will I run into a lot of issues? Are there ways to compress the files other than perhaps zipping them up and storing the zip?
Finally, something I've always wondered about but never really found a good work around for... if I decided to continue with the mixed-mode storage solution, and these I need to retrieve these files for use on a website, how do I secure these files so that someone can't just randomly come and retrieve these files off the server by guessing files names, etc?
I did one work around once where I stored a set of PDFs to a non-web directory like c:pdf and setting permissions for the web account to access them. This allowed me to retrieve them using the references in the DB and provide some garbled filename so people couldn't retrieve it themselves but this all seems rather complicated.
recommend any alternatives to the error provider? What are their advantages?
View 1 RepliesIn my experience, web.config files are widely reviled. In particular, I have found them difficult to manage when you have multiple environments to support, and fiddly to update due to the lack of validation at update-time and the verbosity of XML.
