Client event double click task

[OfficeHeart]

Hello,

Is it possible to attach a eventhandler to a double click event on a task and get the taskId?

Thanks,
Martin

Hello Martin,

You can attach a double click event handler manually and implement your logic there. Here's an example of how to get a task from inside a double click handler:

function pageLoad() {
    var $ = $telerik.$;
    var gantt = $find("RadGantt1");

    $(".rgtTask").on("dblclick", function(e) {
        e.stopPropagation();

        var $element = $(e.target);

        if (!$element.is(".rgtTask")) {
            $element = $element.parents(".rgtTask").first();
        }

        var uid = $element.attr("data-uid");
        var tasks = gantt.get_allTasks();
        var task;

        for (var i = 0; i < tasks.length; i++) {
            if (tasks[i]._uid === uid) {
                task = tasks[i];
                break;
            }
        }

        console.log(task);
    });

}

Hi,

Can you share your code (just the relevant part, demonstrating the Gantt and how you're using it), so that we can inspect it in order to find out why you might be getting this error.

The most probable cause is that the following line is not getting the proper reference to the Gantt control:

var gantt = $find("RadGantt1");

This might be caused by several reasons:
1. Your Gantt has a different ID
2. Your Gantt is inside a naming container, causing its client ID to be different than the one specified in the markup. In this case try using the following syntax:

var gantt = $find("<%= RadGantt1.ClientID %>");

Hi,

When you have new and different issues, please post them in a new forum thread (or in an old one discussing the particular issue), so that we can keep each forum thread concise and relevant to it's title. That way when another person searches through the forum he can more easily find a relevant topic.

As for the issue at hand, again, without relevant code there's little we can say about the problem. Also, make sure you are using the official release of RadGantt (Q3 2014), rather than the beta release (Q2 2014), since there were some issues concerning databinding and CRUD operations that were addressed between the two versions.

pleas give me code 
When clicking gantt  task 
get Task Id 

[Peter Milchev]

Hi,

Once you get the task as suggested by Bozhidar, you can use the client-side API of the task to get its ID:

• https://docs.telerik.com/devtools/aspnet-ajax/controls/gantt/client-side-programming/objects/gantttask-object;
• task.get_id();
