How to save TinyMCE after postback in UpdatePanel

Question

When I click on the button that causes the UpdatePanel to the UpdatePanel , it calls tinyMCE.triggerSave() .

It reloads the panel and the editor appears again, but when I try to call tinyMCE.triggerSave() , the second time I get the following error:

 g.win.document is null 

I got the old instance, but I also delete the control ( tinyMCE.execCommand('mceRemoveControl',false,'Editor'); ) after calling save. Despite this, he is still out of order a second time.

How to fix it?

Answer 1

After a lot of confusion, I found that the fix that @ André Gadonski posted no longer works in TinyMCE 4. This not only does not work, but also does not provide feedback on the console error!

New mceRemoveEditor

I found that this can either be used immediately before reinitializing TinyMCE, or just before updating the ASP update pane using

 var prm = Sys.WebForms.PageRequestManager.getInstance(); prm.add_beginRequest(BeginRequestHandler); function BeginRequestHandler(sender, args) { tinymce.execCommand('mceRemoveEditor', true, 'EditorID'); } 

Answer 2

tinyMCE.execCommand ('mceRemoveControl', however, the editor ');

Before leaving UpdatePanel, it will force tinyMCE to completely be deleted, and then when you add it again, it will not work.

Answer 3

For tinymce 3.2.x, use the following to remove the tinyMCE instance in IE8 or any other browser. Because the tinymce.execCommand function makes the input fields immutable in IE8.

 tinyMCE.remove(editor); //editor is instance of tinymce editor and not editor id 

This will fix the "Allow Failure" error without disabling other input fields on the same page.

Answer 4

I have the same problem. For correction, you can add script code for the create post back element. my button creates the message back, I add it to OnClientClick ():

 <asp:LinkButton ID="lbnSave" OnClick="lbnSave_Click" ToolTip="Add New" OnClientClick="dotim()" runat="server">save</asp:LinkButton> 

and script:

 function dotim() { tinyMCE.triggerSave(); } // this is my attempt at a fix
