I have to simply say thanks for this tid bit …

I have been trying to figure out what was going on the ASP:MENU control for almost a day.

Metropolis12 – No Firefox does not support any of the Microsoft filters as far as I know.

In the ASP.net 2.0 rounded corner drop down menu issue I had above, Firefox did not render a white background, so there was no fix needed.

Kevin,
Thank you for your response! You have helped me solve an issue that I’ve been working on for a long time! I began digging around for some scripting and came up with the following which works great for this (removing the iFrame white flash in IE, just prior to the content loading into the iFrame .) First is applying the chroma filter as you documented above to remove the flash (by instructing IE to filter out pure white, it’s default bg color), the next step is to then disable the filter after a few seconds so that white elements that will then get loaded into the respective iFrame, won’t have the white pixels removed. Here is the javascript I used:

// timer to disable chroma filter in IE iFrame

Best Regards, and thank you for ending my frustrations with this!

Hi J,

I’m sure you can turn the filter on for say the first 1 or 2 seconds then turn it off with JavaScript. Unfortunately, I’m not a Javascript whiz. Here are some reference links that may help on the filter side of things. Sorry I can’t help more on this.

Thank you for this information. I have a question though… I was trying to apply this for a different reason… I have 2 iFrames that I’m loading content into for a site. All browsers are fine, except for IE which flashes it’s default bg color #ffffff before loading in the content for the iFrame.

Using your method above, it does remove the white “flash” I was getting in IE, but it also removes all other pixels that are #ffffff that get loaded into that iFrame from there on out. Is there a way to have it filter out the white background initially and then either turn off once the page has loaded? Or to tell it to only filter out the white background and ignore all other page elements?

Thanks for your time!

Bhavana, if you want to send a link I can take a look. FYI – you’ll never see the iFrame in your project, it is created as the page is rendered.

Another FYI – : ) – ASP.net’s new CSS Adapters remove all these nested tables and iframes from drop down menus and can be *much* easier to style.

I am having the same problem of whitepsace in my menu .I used the code pasted on your site but it did not resolve the issue.My menu is not getting created inside an iframe but in a div tag .It is also being created programmatically in the CS file.

How do I solve this problem?Your help is highly appreciated.
Thanks a lot

Bhavana
