ContextMenu set target

[TheCroc]

Hi

In Q2 2007 we are using the following code to dynamically set the target and open a ContextMenu on client click of a regular html control.

var menu = window["<%= PropertiesMenu.ClientID %>"];
if (menu)
{
  menu.SetContextElementID(obj.id);
}

We're refactoring to use Q3 2008 and can see from the documentation that we should be using "set_targets" instead but this raises an error. Can you provide an eaxmple of how to use set_targets?

Hello there,

Unfortunately this functionality is not available out of the box. However, we have prepared a workaround for you. Put the following lines right after the ScriptManager declaration:

<script type="text/javascript">
        Telerik.Web.UI.RadContextMenu.prototype.addTargetElement = function(element) {
            if(element){
                this._targetElements[this._targetElements.length] = element;
                var eventName = $telerik.isOpera ? "mousedown" : "contextmenu";
                $addHandler(element, eventName, this._elementContextMenu);
            }
        }

        function pageLoad() {
            var menu = $find("RadContextMenu1");
            menu.addTargetElement($get("div1"));
        }
    </script>

You can find sample project attached as well.

Since we think this is a good addition, we have decided to implement the feature for the future version of the RadContextMenu. In fact, it will be available forth from the next internal build.

In addition I have updated your Telerik points.
