This is actually the same code that I used for the BlogEngine.Net extension that I created a while back. However I needed it to be a bit more generic (not BlogEngine specific) and take the code from a text box so I ended up creating an AJAX extender:

CopyToClipboardExtender.zip (2.07 kb)

It's rather basic. The targetID is the link you want them to click on to copy the text. The CopyID is the text box's ID. It most likely will not work in Firefox, etc. and is really only IE specific. However it's better than nothing. 

As far as setting it up, sometimes I get a bit lazy when it comes to explaining how to use some of the code on here. In the case of the AJAX controls, I usually leave out the fact that you need to download the AJAX Control Toolkit. Once you have that and you've added the templates, etc. like it says in the setup, you need to create an ASP.Net AJAX Control Project (I've used the name of AJAXControls, so if you use something different you'll need to potentially change some of the code to point to the correct namespace). From there, you add the code (making sure to have the js file as an embedded resource). Compile and you're ready to go...

Now that jQuery is going to be the norm, the setup process will probably change in the future. Plus I plan on packaging these up at some point like the utilities. For now though I leave you with the code. So try it out, leave feedback, and happy coding.

   

It always seems like there is an endless supply of reports/tables that need to be created. And one of the requests that comes up with them is to make the headers freeze so you can scroll the rest of the information. It's fairly easy to do, just add a div around the table with a set height and overflow set to auto, set the header of the table to relative positioning, and you're done. However, if you've tried this with a Gridview, you'll notice that it gets a bit annoying. It's doable, but it's a bit annoying. So to help out, I created an extender that sets everything up for me:

FixedHeaderExtender.zip (1.54 kb)

It's pretty basic and very similar to the other extenders (uses the AJAX Toolkit, etc.). All you need to do is set the target control to the GridView and set the height that you want the grid to be. You can still format everything the way that you have in the past, etc. and it doesn't change anything along those lines. All that it does is freezes the headers and allows the other items to scroll. So definitely give it a try, leave feedback, and happy coding.

   

If you've looked at my site and scrolled over any of the links, you've probably noticed that a popup comes up (well in IE it does any way, if you have javascript turned on).  So maybe you haven't seen it, but if you have you'll notice that it's a service by Snap. You add in their javascript and they'll automatically add a contextual popup (usually an image of the site) for each link. Depending on your view, this is either very annoying or fantastic.  The main issue with the service that Snap provides is it can't view an internal website. So what can you do if you want to have the same functionality on an intranet?

In a recent post, I mentioned how to take a screenshot of a web page on the fly and convert it to a PDF. We can use the same code (so go download it), to create a similar functionality to the one Snap provides.

LinkVisualizerExtender.zip (3.04 kb)

The zip file above contains two items. The first is an extender. This extender simply takes a div as input and will attach itself to every link inside that div (mouseover and mouseout events). When the mouseover event is fired, it positions a div underneath the link, and calls a handler (the second item in the zip file) to load an image. The handler is called PageToImage. This item takes in a max size for the resulting image and a URL which you want to change into an image. This handler uses the code from the other post to get the screenshot, so you'll need it as well.

Please note that this is very basic example and was intended more as a proof of concept than anything. I'd definately add a div as a secondary target that would hold the image of the link (so I could format it however I wanted), add a property to define the size of the image (at present it's static at a max size of 500 pixels), maybe another property to define where I wanted to place the item (top, bottom, left, etc.), and maybe some sort of animation if you really want. None of that would be too difficult to add really.

The handler also needs to be changed as it doesn't know where you want to place the images (there's a FolderName string object that needs to be filled in). Other than that though, it works fine (even caches the item on the client side as well as on the server). The only thing I might add there is some code to have the server side cached item die off after X number of days. That would be it though.

Anyway, download the code, try it out, and happy coding.
