changing backgroung color name in css file while selecting dropdown

[suganya]

hi

I have a dropdown with values as blue & green. If I select "blue" from the dropdown then, all the backcolor which I have specified as green in seperate css class file should change into blue. So that I can see all the buttons view which is in green color as blue immediately in the current page. what coding should I give in the selected index changed event of dropdown....

Most ASP.NET Controls have a property called CSSClass.
Since you have CSS classes "blue" and "green" all you have to do is set the controls' CSSClass property to be "blue" or "green"

Eg:
[code=vbnet]
myAspNetControl .CssClass = "blue"
[/code]
