Tooltip visibility toggle based on task field

[James]

Is there any way to toggle tooltips for different tasks in the Gantt based on a field set in the model? We have some tasks that require tooltips, and I made a template for them that displays some model fields. When a top-level (i.e., summary) task does not contain children, I've added a task that displays No Tasks as its title (per user requirements). It is for these 'No Tasks' tasks that I would like to completely toggle off tooltips. Any suggestions?

Hi,

Instead of assigning a string as the template, you can specify a function, where you can modify the template based on the task.

I can and have done that for different task types already. What I am trying to do is completely turn off tooltips for specific tasks. I'm not sure that's feasible. Here's the latest version I tried - all selected items are as required, just am unable to turn off the tooltip for some tasks. Not setting anything in the tooltip template causes a small, empty tooltip to display.

function onDataBound() {
    var gantt = this;
    ...
    gantt.element.find(".k-task-single").each(function (e) {
        this.style.border = "0px";
        this.style.height = "20px";
        var z = this;
        var xx = $(z).find(".taskProj"); // a class I added to a span inside the wrapper div in the task template
        var xxx = xx[0]; // there should only be one item in this array
        if ($(xxx).data("pid") === null) {
            $(z).tooltip.visible = false; // this isn't working
        }
    });
}

Hello,

Thank you for clarifying. Since you can embed javascript code inside the template, you can use the following approach to hide the tooltip for certain tasks:
