The current release of RichTextBox does not maintain state when it is set to inVisible. I would imagine that the Toolbar control is setting its contents to invisible and this is why the state is being lost. This is an omission on my part and it was registered as a bug a few days ago. It will be fixed in the next release, which I expect to be available in the next few weeks. For the time being, the workaround PaulD has suggested is a good one. You would also be able to use ViewState to store the Text value.

Thanks guys for the help but I think what I am seeing is a little different from what you are describing. The text from the RichTextBox is only lost when the client's cursor only goes directly from the RichTextBox to the ToolBar that postback the page, without passing go or losing focus on the RichTextBox. When this happens the data is does not persist through even the form_load method of the page so the workaround Paul suggested can't help. However, If the client clicks on any other type of control the data persists through the postback, additionally if the client losses focus on the RichTextBox and then regains it before posting the page there is no problem. So the problem only occurs if focus is never lost on the RichTextBox, I was thinking the best work around would be a JavaScript function that changes focus from the RichTextBox, but I was having some problems getting this to particularly work on down-level browsers. Thanks again... By the way the control is really sweet. -----Original Message----- From: Ollie Cornes [mailto:Click here to reveal e-mail address] Sent: Tuesday, June 25, 2002 3:12 AM To: aspngrichtextbox Subject: [aspngrichtextbox] Re: RichTextBox and ToolBars Hi Paul and Paul, I think these issues are one and the same and I'm sorry you are seeing issues with it.

If the Toolbar is not causing that to happen nor is it causing a form submission, then that would explain why the contents are lost. Just to check - when you click the Toolbar, there is no post back occurring and it is a purely client-side event? I'm going to enter this as an issue to be looked at for a future release as I'd like the control to work seamlessly with the Toolbar. Whether this can be achieved is another matter, but if it's possible it'll be done. For now as a workaround, your idea of changing focus is a good one as that will ensure the document is copied to the right place and maintained correctly. If you can add script to the Toolbar button, try adding this: onclick="this.focus();"; I would be interested to hear how you get on.

There is no click side click event for the toolbar so OnClick doesn't work, but onmouseover works fine, and for some reason the focus is only lost on the RichTextBox for a split second so it is hardly perceptible to the User. To answer your questions, The Toolbar DOES postback the page. It must do so without ever removing getting focus. However, if the RichTextBox should copy its contents to the hidden form field every time the page is posted, this is not occurring. So you may want to play with it to see if it is indicative of a larger bug. However, I am happy with the workaround, and with the product in general.

I think what we're seeing here is a rather beautiful ballet-like performance as a series of unrelated restrictions in RichTextBox, IE and ASP.NET interplay! :-) I am not sure if there is a good reason for the LinkButton control not firing the onsubmit event, but it's certainly not helpful. However, I'm very glad you have found a solution that works for you and I appreciate the feedback.
