when the page loads am trying to get the number of rows in the i5Grid but am not sure why it shows 0 row count. The only time where I could see the row count is when the i5Grid is selected.

Below is the sample code:

var grid_c0c0 = new com.sap.xmii.grid.init.i5Grid("grid template path","query templ path",true);
grid_c0c0.registerCreationEventHandler(ceController.addObject("c0c0",grid_c0c0));
grid_c0c0.draw("gridc0c0");
alert("initial"+grid_c0c0.getGridObject().getRowCount());

I couldn't figure out what is the issue. Any help would be Appreciated.

Thanks

Sap

I think some async goes on and you may be trying to use parts of the grid object before they get completely instantiated. Try triggering your logic with the FirstUpdate or Update events. There won't be any rows or data in there anyway until those are fired.

Here is the code sample which I tried with first update event and I still get the same error. Am not sure if anything is wrong with my code.
