I'm using the RTB on a page that has multiple panels. I'm navigating =
through the panels with a next and back button that sets the proper =
panel to visible or not visible. When I set the panel with the RTB to =
not visible I lose the text that was in the box. How can I keep that =
text there?

Thanks,
RIcki

I have a page that contains 14 different RTB controls that had to be
collapsed or expanded at any given time. What worked very well for me
was the use of <asp:panel> control that renders to a <div> tag. Then I
just wrote some client-side code to hide or show the panels by changing
the "display" style property.

Hope this helps!

Ricki,

The current version of RichTextBox doesn't work well in the scenario you
have. If you hide it, the document is cleared. This will be fixed in the
next release, but for now Jeff's solution will work well. His solution
may actually be better as it avoids a round-trip to the server and so
the experience for the user will be a little better.

I'm sorry for the problems this issue has caused - it will be sorted
out.

I've hit this problem doing exactly the same thing and it seems that
RTB isn't maintaining state, although I understand this is due to be
fixed in the next release.

To get around it I just load the contents into viewstate using:-

public string pageContent {
get {
if(ViewState["pageContent"]!=null)
return ViewState["pageContent"].ToString();
else
return "";
}
set {
ViewState["pageContent"] = value;
}
}

When you hide the panel that RTB is on I use:-

pageContent = RichTextBox1.TextXhtml.ToString();

And then when I display it I use:-

RichTextBox1.Text = pageContent;

THat seems to do the job.

Thanks for your help with this. I'm having an issue with it though. =
Right now, I'm going back to the server for showing and hiding my =
panels. So, in effect my pageContent property is getting reset with =
each postBack. I'm new with .net so I'm certain there is a better way =
to do this. Any suggestions?

public string pageContent {
get {
if(ViewState["pageContent"]!=3Dnull)
return ViewState["pageContent"].ToString();
else
return "";
}
set {
ViewState["pageContent"] =3D value;
}
}

When you hide the panel that RTB is on I use:-

pageContent =3D RichTextBox1.TextXhtml.ToString();

And then when I display it I use:-

RichTextBox1.Text =3D pageContent;

THat seems to do the job.

Hi Ricki,

I'm sorry you've got problems. This issue is caused because RichTextBox
is not correctly maintaining the state across postbacks when it is
Visible=false. This will be fixed in the next release, but for now your
two options top work around it are:

1. Use Julian's code to save the document in the ViewState object
between postbacks.
2. Use a client-side solution to hide the editor.

Does that help?
