I think downlodify needs flash to work. Without it you are restricted to the size of records the grid stores.
Sorry, have no time to change those JS plugins... I think if possible Ext JS community needs to fix Downloadify by flash removement (or replacement). Hope such solution is existing. Need to be implemented.
P.S. I haven't got why the Downloadify developer used flash. Why he made such solution.
I am trying to give my custom image by specifying downloadImage attribute in the config, but any image i put in the image flickers and on clicking hides. Can anyone please help if seen this issue or what I need to do exactly to specify my image rather using the download.png provided by the library.
{
xtype: 'exporterbutton',
store: <<my store>>,
downloadImage: <<path to image>> //pointing to my image on my local
}
