Feb 11, 2010
I have 2 DropDownList in my page:
[Code]....
and in the code behind I have the following:
[Code]....
Now, when you select an item from the 1st DropDownList, you go t the right page, but then if you click on the browser back page, and select an item from the 2nd drop down, still the 1st drop down event will be fired and then you land on the Fixtures.aspx page again instead of Results.aspx.

I have an AJAX enabled ASP.Net 3.5 app in which I have:
A Master PageA Web Content PageA User ControlMore precisely, there's a Placeholder control in the Web Content Page into which one of many User Controls are loaded (one at a time or none at all).
The basic User Control I'm working with has a bunch of Labels and one DropDown ListBox. The latter control is a date selector - ie. June 2010, May 2010, April 2010, etc. When the user changes the date, since AutoPostBack = true for the control, a PostBack occurs. But when this happens, the User Control disappears!
All I want is for a partial postback to occur so that I can use the new date to repopulate the various Label controls. I even put the Placerholder control in its own UpdatePanel but this didn't resolve anything - the User Control still disappeared.

This is the code being generated by the HTMLEditor:

Is Regex.Replace the best way to replace these items? I need to keep the text between the opening and closing statements as well as ensure the proper formatting to the text so doing just ReplacementText.Replace will not work. I've tried a number of different things to try and get Regex.Replace working properly but keep having different issues and different things happen. But why it's not using the the closing span for the bold statement but using the closing span for the italics is beyond me.
