Hi,

Take a look at this link: 

http://help.k2.com/onlinehelp/K2smartforms/DevRef/1.0.7/default.htm#Adding_Custom_Javascript.html%3FTocPath%3DCustom%20Controls%7C_____3

It details how you can add custom javascript to an existing control. 

Your link doesn't help.

The question is how to add a method which can be triggered by rules. Not how to include Javascript!

Any Idea? Anyone?

Edit: So here's what I found out so far...

Xml:

  <ExecuteMethod>ToolbarControl.execute</ExecuteMethod>
  <Methods>
    <Method ResultType="None">
      <Name>ResolvePermissions</Name>
      <DisplayName>Resolve Permissions</DisplayName>
      <Description>Yadda</Description>
    </Method>
  </Methods>

JS:

ToolbarControl = {

>...]

        execute: function (objInfo) {
            var parameters = objInfo.methodParameters;
            var method = objInfo.methodName;
            var result = "";
            var currentControlID = objInfo.CurrentControlID;

            switch (method) {
                case "ResolvePermissions":
                    // some code here
                    break;
            }
        }
    };
})(jQuery);

But still missing is how to trigger a method implemented at the server control (code behind)...

Edit:

Found it ;)
