Invisible to Visible and Back Again!

Reply Quote

I am a new customer, considering purchasing CuteEditor. The other textbox products I have found have some of the same issues I am encountering with CuteEditor, but many of them have failed to give me much input, so here goes.

I am trying to embedd the Editor into a Dialog from AJAX and/or ComponentArt.Web.UI's Dialog control. The problem is that the Editor renders even when the dialog has not yet been shown (whereas the editor should remain invisible until the dialog is shown). Setting the Editor to Invisible DOES solve the rendering issue, however once it is set to invisible, I find it impossible to set it to Visible again, as every call I make to the code seems to tell me the object doesn't exist because it was not rendered since ..it was invisible. . .

Is there a reason why CuteEditor renders even when it is inside of a hidden parent control? Is there any known solution for this problem?

Thank you for your time,

Derek

That would be adequate for what I need. My goal was simply to hide the Editor until the dialog was shown, then have a button/link to make it visible.

How would I go about sending you something?

derek,

I have checked your project and find out your control use visibility: hidden to render the dialog code. In my example, I am using display: none.

The display: none and visibility: hidden CSS properties appear to be the same thing, but they aren't.

These two style properties do two different things.

visibility: hidden hides the element, but it still takes up space in the layout. (That's why all controls are rendered.)

display: none removes the element completely from the document. It does not take up any space, even though the HTML for it is still in the source code.
