Performance problem with "datgrid:detailview"

[rezzonico]

Hi all,

I am experiencing some performance problems when using "view: detailview" in a datagrid.

As you can see in the following graph without "detailview" the response time is very good.
When using "view: detailview" the response time is 6 times slower.

In firefox the default value of max_script_run_time is 10 seconds.
This means that if I want to display more the 5000 lines I must increase the value of max_script_run_time.


Is this a bug ?
Is it possible to speed up the process ?

Thanks in advance
Miche

How do you define your detail view? Please show an example to demonstrate your issue. If you are displaying large rows without pagination, please try to use the scrollview.

Hi stworthy,

in all my datagrids I use pagination.
But in this example I must display all the rows in order to print them.

Here the first example without "view: datailview".
As you can verify the responde time is very good.

And here the second example with "view: datailview".

Thanks in advance for your help.

Please define an expander column in 'columns' to improve rendering speed.

Code:

columns: [[
	{field:'_expander',expander:true,width:24,fixed:true},
	{field:'Assetnum',title:'Apparecchiatura',width:25,editor:'text',sortable:true}
]],

Hi  stworthy ,

as you can verify with the following link, after implementing your solution, the response time is better:

Instead of 27 sec, now the response time is only 15 sec.

Thanks a lot !
