Naming a document element problems (trying to getElementByID() but the id's of the control are staring with _'s, which are not valid)


This page is an almost working implementation of http://www.markjrubin.com/286219/ex1.html

When viewing the HTML source, you'll see the two files are very close, with the difference being that the spans in the working on faulty version are named "_ctl0_Strategy0" instead of "Strategy0". That causes the getElementByID() javascript function to fail because id's staring with _'s are not valid). Since as far as I know, I can't control the control's naming prefix (via a C# command), how do I get around this?

You could just append the _ctl0_ in your JavaScript.

Are you making this controls available on the server?

Hi Mark, Eric
ctlo_ prefix probably concatenated by UserControl or some other container. appending ctlo_ in most cases is not a good idea. Better solution is using ClientID at server to determine element id at client. See this post.

Treeview control: how do you access client id's for each node's checkbox?
Is it possible to get the client id's for the checkboxes that are created by a treeview control?  I need to create some javascript that will manipulate the checked status of the boxes on the client side, but can not figure out how to determine the client id's for each checkbox. I am in a situation where the tree can have 4 levels of nodes, and they are not populated unless the user expands a node.  This causes the client id's to constantly change as they are numerically numbered from the top down. Thanks, Billy You can get the ClientID of a checkbox inside javascript as follow...

Can I hide a user control's control from the hosting page's client script?
Okay, my previous question was not unswered and I guess you can't hide a control's panel with server code then show it with client code. Now this is what I try to do: on the hosting page's onload event, call a function to hide the user control's penal. Here is the deal: the user control was looped as many times as data required. So the penals will be name mypanel1, my panel2, etc... that is not even a problem if I know if the following is true: * Do all server codes finish running before the page get sent back to the client? Say the database gave me 5 penals, I can then determine how...

All-- Received this error from a PB 7.0.3 app running against Sybase 12. One of the suggested workarounds is to run sp_configure against Sybase to enable Unicode. (We are not at all in favor of doing that.) The other alternative is to translate our ANSI-codepage app into Powerbuilder for Unicode. What *is* PowerBuilder for Unicode, and how do we get our hands on it? Is it an add-on, or is it bundled with the ANSI version?

When viewing a ng I'm having problems with choosing what to view. It's like this. When scrolling through the posts my reader wants to view every thread. Let's say I read a particular post. It's highlighted because I chose to read it. Then after I am done and scroll down, instead of the highlight moving, it stays centered and wants to read/open every post that I'm scrolling through even though I haven't clicked on it and I don't want to read it. This also affects choosing which ng to read. Things want to scroll when I am not wanting them too. When I ...
