Hi Naomi,

I could probably help with a clearer and more concise explanation, perhaps additional code excerpts could help understanding.

>Hi everybody,

>Now, I have an Edit Box for entering HTML and I have a Preview button on the form to show that HTML in the Browser. I want this prevew button to be enabled when something is entered in the HTML.

>this.parent.cmdPreview.Refresh()

>However, nothing seems to happen, the code in InfoChanged method works, but my button remains disabled even after I typed a few keystrokes.

>So, I am wondering what is the source of the problem - is it because the "binding" of the value in edtHTML to the table.HTML happens in the Valid event and therefore checking Alias.HTML doesn't help?

>What do you think?
