i try to use grid with smart rendering and paging method.
With first column master checkbox to select row.
Problem is i working with big size data 4000+ , a master check box is a picture
So it have to render picture every row,when i loading data it take time to load.
How can i solve this problem?Or what i miss? 
Sorry , i not master_checkbox but it 's a check box .
How do you manage this case with more than 4000 record and not use smart rendering?
Smart rendering mode is incompatible with paging mode
You should try to use smart renderinfg mode or paging mode.
Yes , i just use only paging mode not smart rendering.
How do you manage this case with more than 4000 record and not use smart rendering?
If you have any troubles with the speed of loading of your grid you should enable smart rendering mode or paging mode.
Please read the tutorial about the increasing of performance:
