nanich, if I understood you correctly: Only one level is supported. For everything else, you have to stick with a tree. Hint to the ExtJS guys: Seems that a multi-level tree control with rows and sorting seems to be a popular request
1. Fill the grid using JSON like you would usually do.
2. Specify "reader" : "json" in the config (see above).
For anyone interested in downloading the subdata on-demand via ajax/JSON one way is to change the expand handler around line 169. I changed the function to take 4 parameters, the fourth being the rowIndex and added an Ext.Ajax.request to my server. The success method calls subtableRowExpander.updateRow(rowIndex) to immediately render the subtable. So the initial page load includes an empty array for each row's subdata attribute and when the row is expanded the actual data is requested.
it's really nice plugin and suits me requirement.
right now i am generating simple grid using DWRProxy and JsonReader.
can you please suggest me how to use your plugin with DWRProxy. Because my data is coming from Java side.Response object is like Collection object inside object.
