I was -- even now -- trying to this and thinking there must be a better way! David October 15, I need to review my jquery selector syntax again. I've been using the following function for a while, which doesn't rely on jquery, but now that I use jquery pretty much by default, I may switch. Cristovao Morgado October 15, Chris Brandsma October 15, I like the postfix fetch on ID, but it can take a while when dealing with large pages, so I gravitate to the global definition.
But, now I've switched to Asp. Because I can no longer count on my page being in a particular directory hierarchy, I can't hard-code my Ajax method names probably a bad idea anyway. So I have Url.

Anyone know how to make an jsx just like the aspx we have with mvc? Dave Juth October 15, But it's a pain and I know it's fragile. James Hughes October 15, Class selection on large DOM's tend to be significantly faster then attribute parsing plus if someone then introduces a new element, or a new instance of your user control of uses your control inside a repeater you get into trouble.
DotNetShoutout October 15, Nicholas October 15, How much faster will depend on your usage, obviously.. NET ClientIDs with jQuery I could never being myself to deal with this nightmare that is part Master pages, so in spite of much convenience I opted not to use them long ago. Pathing in MVC especially for page relative content is a royal pain - in fact I'm still playing around with what feels right in terms of where to place script related script and CSS files. This is definitely one place where having a fixed page location and folders that can hold related data is easier.
As to selector speed that many mention here: Yes using Attribute selectors is slow and if you do need the extra performance the explicit declarations are more effective. However, I suspect in most situations we're looking for a single ID'd element and that look up and a single lookup likely isn't going to kill perf too badly.
And if you want to use the explicit object scoped client IDs you can check out the ScriptVariables component which will automatically spit out client IDs without manually adding them to the document. I've been using that approach successfully for quite some time and it adds basically two lines of server code. Prefixing the attribute selector with a specific element prefix like input[ This is obviously a convenience function meant to make it easy to retrieve the IDs without having to think about the underlying logistics of how client IDs work.
Steve - re: Master Pages. I always contemplate not using them in my apps for the naming container mess they create, but they are so damn useful that I always end up using them anyway. Chirstavo - Using class selectors is a good idea but it requires some extra effort on your part to explicitly tag controls with the class name you want for an Id. I suppose ASP. NET 4. Mark Kadlec October 15, Thanks for sharing! Your task can be solved without using ClientID's.
You can use a TextBox's Load event to specify it's client-side text changed event, based on the row key:. Then, in the server side "Done" button, click the event handler.
