Annoying VS 2010 IntelliSense markup problem - after some recent updates

velio — Wed, 20 Oct 2010 08:09:13 GMT

Honestly I have no idea exactly when and which of the recent updates is causing the problem, but at one point I noticed that VS2010 IntelliSense marked tags on standard web controls as unknown.

Further more: The IntelliSense stopped to support the standard asp: tags.

As you can imagine, this was really annoying problem for me.
So, I dig around half an hour and found a solution to the problem.
Seems to me like something in the signature of the System.Web.Extensions assembly was changed.
In order to fix the markup IntelliSense I had to remove the details assembly reference info in the Web.config, where the asp tags’ prefix is defined for web extensions.
Here is how it looks before the change:

And here is after the change:

Now, I have back my good pal IntelliSense on markup:

Hope this could helps to anyone experiencing same problem.

Extension Methods: HtmlTextWriter part 1 - RenderTag

velio — Tue, 17 Aug 2010 06:51:36 GMT

So, for me case is clear guys: “Static helper methods are dead, long live the Extension Methods.”
Since extension methods were out, I become a big fan of them.
For example, instead of:

     StringHelper.Encode(“Some secret”);

it looks much more nice and natural to me:

    ”Some secret”.Encode();

I have implemented and I’m using tons of extension methods so far and I decided to start a category in my blog where to share some of them with you guys.
Hope all those methods to be useful to you too, as they are to me.

First of the series will be a couple of extension methods to HtmlTextWriter.
You know, as a web and especially web controls developer, I use it much and that’s why I like extending it.

During my development I found a lot of lines where I just render and open tag and then immediately the closing (end) tag is rendered, like:

    writer.AddAttribute(HtmlTextWriterAttribute.Id, fieldName + "_Error");

    writer.AddAttribute(HtmlTextWriterAttribute.Class, "field-validation-error");

    writer.RenderBeginTag(HtmlTextWriterTag.Span);

    writer.RenderEndTag();

The other case I often found myself using is: open tag, write some content text and closing the tag, like:

    writer.RenderBeginTag(HtmlTextWriterTag.Span);

    writer.Write("allow editing");

    writer.RenderEndTag();

I have developed some snippets for Visual Studio, which you could find at my website, in order to speed up typing such a kind of code bocks, but at some point I said to myself: why not merge those lines in a single methods. Of course, in a single extension method .

Here are the simple extension methods I came with:

    /// <summary>

    /// Renders the tag.

    /// </summary>

    /// <param name="writer">The writer.</param>

    /// <param name="tag">The tag.</param>

    public static void RenderTag(this HtmlTextWriter writer, HtmlTextWriterTag tag) {

        writer.RenderBeginTag(tag);

        writer.RenderEndTag();

    }

    /// <summary>

    /// Renders the tag.

    /// </summary>

    /// <param name="writer">The writer.</param>

    /// <param name="tag">The tag.</param>

    public static void RenderTag(this HtmlTextWriter writer, string tag) {

        writer.RenderBeginTag(tag);

        writer.RenderEndTag();

    }

    /// <summary>

    /// Renders the tag.

    /// </summary>

    /// <param name="writer">The writer.</param>

    /// <param name="tag">The tag.</param>

    /// <param name="content">The content.</param>

    public static void RenderTag(this HtmlTextWriter writer, HtmlTextWriterTag tag, string content) {

        writer.RenderBeginTag(tag);

        writer.Write(content);

        writer.RenderEndTag();

    }

    /// <summary>

    /// Renders the tag.

    /// </summary>

    /// <param name="writer">The writer.</param>

    /// <param name="tag">The tag.</param>

    /// <param name="content">The content.</param>

    public static void RenderTag(this HtmlTextWriter writer, string tag, string content) {

        writer.RenderBeginTag(tag);

        writer.Write(content);

        writer.RenderEndTag();

    }

Now using those extension methods the sample lines of code above will become:

    writer.AddAttribute(HtmlTextWriterAttribute.Id, fieldName + "_Error");

    writer.AddAttribute(HtmlTextWriterAttribute.Class, "field-validation-error");

    writer.RenderTag(HtmlTextWriterTag.Span);

and:

    writer.RenderTag(HtmlTextWriterTag.Span, "allow editing");

Hope this helps.

Velio

VisualStudion 2010 Javascript Outlining 1.0

velio — Fri, 04 Jun 2010 23:06:00 GMT

As a Web 2 developer I found myself dealing with fast growing JavaScript code files.
And I really missed the code regions in Visual Studio, which is a nice way to organize the code blocks and focus on reasonable small amount of code.
There are some macros available out on the web for placing a regions outlining in JavaScript code editor.
I was not fully satisfied with macros and the fact I have to manually run them (even with a shortcut keys) every time I open the JavaScript file.
Thus, I have spend some amount of my time and came out with a Visual Studio 2010 Editor Extension for JavaScript Oulining.

Even, if this first version is simple as functionality it gave me much better JavaScript code experience.
So, I decided to share it with you guys and hope it helps you too.

Please, find the visual studio package here

Visual Studio 2010 is out now.
It is great the new Visual Studio 2010 allow usage of code snippets widely now.
Apart of that, the cursor is goes at wrong place after inserting some of the HTML snippets, which breaks the nice continuous typing experience

Have same problem like me?
Do you know you can edit and "fix" them.

Check out this short video, where I for example change the standard textbox snippet

Hope this helps,

GoogleMap Control JS with Pseudo-Named functions now

velio — Sun, 22 Nov 2009 18:59:56 GMT

I’m working recently on next release of GoogleMap Control v4.1.
As I have mentioned - I’m switching from anonymous to pseudo-named JS function for that release.
All the effort made, was for a better JS debug and error feedback experience.

At least, that’s the theory.
However, today I did some work on the control again and had a chance in practice to prove I was right.
I got some JS error during my work, but the information I have now in the call stack is much more useful than just a list of anonymous function.

Here is a simple example of what I mean:

In this particular case, I just mismatch the functions’ bodies , but you get the idea, right.

Generic extension method for a safe item value fetch from HttpSessionState.

velio — Fri, 09 Oct 2009 06:46:59 GMT

del.icio.us Tags: ASP.NET,C#

Hi there,

Here is an extension method for getting a value from the session in a safe manner.

        1: static public bool TryGet<T>(this HttpSessionState session, string key, out T value) {

       2:  

       3:     bool flag = false;

       4:     value = default(T);

       5:  

       6:     if (session != null) {

       7:         object objectValue = session[key];

       8:         if (flag = (objectValue != null && objectValue is T)) value = (T)objectValue;

       9:     }

      10:  

      11:     return flag;

      12: }

The usage is simple like:

       1: bool flag;

       2: if(this.Page.Session.TryGet<bool>("MyFlag", out flag)) {

       3:     // TODO value exists and can be used

       4: }
