Thanks. It's weird not wierd. Actually it's not even weird. It's just reusable.

Evan, Thanks for your advice! How do I make the usercontrols event handler listen for the containing page's button click event? Would it be something like ... handles me.parent.page.findControl("btnPreview")_click() or something like that? "Evan Freeman" wrote: Are these controls dynamically created? Anyhow the method I told you should work, just expose all the generated id's as an array, and then loop through. I mean you are specifying an ID of some kind in the markup, if not then you need to rethink what your doing. Another way to do it would be to expose an event handler in your control and make them all listen to the click event of the preview button, then do your CssChanging from with in that. -- Evan Freeman Evan.E.Freeman (AT) gmail (DOT) com http://evanfreeman.blogspot.com "foton" <jbhopper (AT) newsgroups (DOT) nospam.com> wrote in message news:F4BA8669-8A1A-49C8-85F7-735DCD294A77 (AT) microsoft (DOT) com... I'm sorry that my question isn't clear. I have an aspx page which uses a master page. In that aspx page I have 9 instances of the same usercontrol. I have other pages with different numbers of this usercontrol. Each usercontrol has a button named "btnEdit". When a 'preview" button is clicked in the aspx page I need to hide the btnEdit buttons. Each will have a unique id thanks to asp's efforts to keep them unique. The "preview" button's click event fires in the aspx page's codebehind AFTER the 9 usercontrols and their edit buttons have loaded. So what would be a way to change the cssClass of each of the usercontrol's btnEdit buttons as a result of the "preview" button being clicked in the containing aspx page? Thank you, "Evan Freeman" wrote: One it doesn't mangle the name per say. You could easily expose the generated name to your client side script. asp:Button ID="MyControl" runat="server" Text="Foo"/ var control = <%MyControl.ClientId %>; document.getElementById(control).cssCLass = "CoolBeans"; Second why would you want to change the style before the elements are loaded, you'd just spit out errors, the dom needs to be ready befor eyou start manipulation of tags. Anyhow the above should let you do what you need client side. It's not perfect I typed it from memory. Enjoy! -- Evan Freeman Evan.E.Freeman (AT) gmail (DOT) com http://evanfreeman.blogspot.com "foton" <jbhopper (AT) newsgroups (DOT) nospam.com> wrote in message news:374A274A-E13C-4F42-90F8-04E2A0DA46BE (AT) microsoft (DOT) com... I can't make the change client-side because the aspx page has a master page and asp mangles the names of controls to keep them unique. So I've tried to make the change in the code-behind of the aspx page or the master page but the button_click event is always handled last, after all of the parts of the page have loaded. Thanks! "foton" wrote: In the aspx page, in the button_click event handler, I set the cssClass of a button in a usercontrol contained by the aspx page. Since the event handler fires after the usercontrol is loaded, that doesn't work. How else to approach this?

What code are you using to change the CSS class, and what event is that code in? -- Nathan Sokalski njsokalski (AT) hotmail (DOT) com http://www.nathansokalski.com/ "John Hopper" <jbhopper (AT) newsgroups (DOT) nospam.com> wrote in message news:9C8ADC19-41FE-49E7-947D-E32861D8E5CD (AT) microsoft (DOT) com... Hello, I have a button in an aspx page. When that button is clicked I want to change a css class in a usercontrol in that page. However the button's click event is not raised until after the usercontrol loads, and there is no postback after the click event. How can I do this? Thank you, |
