The following sample shows an example of adding a custom button in C# code and configuring the image, tooltip, etc. in JavaScript

http://richtexteditor.com/demo/custom_buttons.aspx

Is there a way to do it all in C#? 

Hi frJericho,

For now has not the way to add custom button all by the server side code. We will add this in the future version. Sorry for your inconvenience.

Is the JavaScript code to configure buttons documented? I can't seem to find any documentation.

For example, I notice in a few example that we can set the icon on a button with:

this.set_imagename("openfolder");

I am guessing this works because RTE knows what the "openfolder" icon is but what if I want a custom icon? Is it possible to do something like:

this.set_image("http://mysite.com/images/myimage.jpg");

Dear frJericho,

The toolbar image path solution in  RTE likes the below code

1.  this.set_imagename("openfolder");

2. RTE will find "richtexteditor/images/openfolder.png” as the image source in this demo.

Regards,

 Jeff,

I don't think you took the time to read to example I gave you. I am trying to use a custom image on my button. The image is not located in the RTE path. The image in my example was http://mysite.com/image/myimage.jpg

Please note that this was very easily done in CE 6 with C# code similar to this:
