Stop OnClientNodeClicked when double clicking?

[Zonk]

As in the topic - I have both events subscribed and I want to prevent NodeClick from happening when double click occurs, how can I do that?

Hello Zonk,

The issue with handling both events is that the OnClientNodeClicked event occurs before the OnClientDoubleClick.  The only way I can you handling this issue would be to delay the code being executed in the OnClientNodeClicked event and then stopping the code from executing in the OnClientDoubleClick event (if it occurs). So something like this:

var delayedClickEvent;

function OnClientNodeClicked(sender, args) {
    //  Store variables you need from event to be used in the delay click method
    delayedClickEvent = setTimeout('PerformDelayedClick()',500);
}
function OnClientDoubleClick(sender, args) {
    clearTimeout(delayedClickEvent);

    // Double Click Code
}
function PerformDelayedClick() {
    // Delayed Click Code
}

So in the OnClientNodeClicked event you create a timeout to perform the click event and hold a reference to the timeout. In the OnClientDoubleClick you clear the timeout, so the code doesn't execute, and perform any logic that needs to be done.

I hope that helps.

Thanks Kevin for solution!

Hello Kevin,

Just one addition - sometimes depending on the browser and the delay time, a single click will occur twice. To prevent that you can add the followin line in the OnClientNodeClicked event, before you set the timeout:

if (delayedClickEvent) clearTimeout(delayedClickEvent);
