Hi,
I observed a strange behaviour when testing webdatamenu under Firefox 14.0.1, sometimes client itemclick won't fire.
After playing a bit with this behaviour it seems that, if the first time you click the item (let`s say Nodo1.1 in the sample), clicking on the item while moving the mouse, as if it were a tiny drag caused by the speed or hurry of the user. After that, item click won't fire. It does not seem to happen on IE. I know that it sounds strange but it is more normal than it seems.
I am using the last service release (12.1.20121.2048).
Any hints?
Sample:
<script> function nodeclick() { alert("click"); } </script>
<ig:WebDataMenu ID="WebDataMenu1" runat="server"> <ClientEvents ItemClick="nodeclick" /> <Items> <ig:DataMenuItem Text="Nodo1"> <Items> <ig:DataMenuItem Text="Nodo1.1"> </ig:DataMenuItem> </Items> </ig:DataMenuItem> </Items> </ig:WebDataMenu>
Thanks.
Hello rickycl,
This is caused by the browser. If you test this under different browsers you will observe the same behavior - when there is dragging with the mouse button down the click event is not fired. Maybe just the time for dragging required to cancel the click event is slightly different for each browser. However you could instead handle the mousedown event for all node elements, for example using jQuery:
$('#WebDataMenu1 li').mousedown(function () { alert("click");});
Let me know if this helps.
I understand what you say but what I observed is that after there is a "drag" over a datamenu item when you try clicking again, without moving the mouse this time, itemclick doesn't fire.
Hi rickycl,
Could you provide a sample replicating this behavior as I am so far unable to reproduce it. If I click on an item without moving the mouse, ItemClick is fired.
Using the code from my first post, in Firefox 14.0.1,
1 - Enter the page
2 - Click the inner item, moving the mouse over the item (as if you were a normal user that doesn't now about this issue)
3 - Click the inner item again, this time with the mouse still.
Note: I am "opening" the outer item by hovering but without clicking, if I click on the parent node in order to see the child node it doesn't occur.
I am still unable to reproduce the issue. This is what I am doing:
Do these steps reproduce the issue on your side? I used NetAdvantage v12.1.2012.1.2048, Firefox 14.0.1.
Between steps 2 and 3 move the mouse out of the menu and then hover "Nodo1" and proceed to step 3.
NOTE: it must be the first thing you do on the page, if you click, for example, Nodo1 first then the issue doesn't happen.
I checked ig and ff version and are the same. I am runing the application in debug mode in visual studio 2010's development server on windows 7.
Attached you will find the exact code just in case.
Thanks!
I was able to reproduce the issue. However, I tested the same sample with the latest internal build and the issue did not occur. So the fix will be available in the next service release, projected for August 24 - http://ko.infragistics.com/help/service-releases/.
