Tree Grid/List Grid not loading JSON data

[pchenna1]

Hi,
I'm trying load JSON data to ListGrid and I'm not seeing any records been listed.I'm seeing 15 records after executing eval.
Please suggest on this.What i'm missing here.

public void onModuleLoad()
	{

		final ListGrid countryGrid = new ListGrid();

		countryGrid.setWidth(400);
		countryGrid.setHeight(224);
		countryGrid.setShowAllRecords(true);
		countryGrid.setData(loadData());
		countryGrid.draw();
	}

	private ListGridRecord[] loadData()
	{
		String jsonString = "[{    \"continent\":\"North America\",    \"countryName\":\"United States\",    \"countryCode\":\"US\",    \"area\":9631420,    \"population\":298444215,    \"gdp\":12360000,

	public static native ListGridRecord[] jsonToRecords(String jsonString) /*-{

Thanks beforehand.

Thanks for the reply.Below additional lines solved the issue and grid has been loaded with data

		ListGridField codeField = new ListGridField("countryCode", "Country", 128);
		ListGridField nameField = new ListGridField("countryName", "Name", 128);
		ListGridField capitalField = new ListGridField("capital", "Capital", 40);
		
		countryGrid.setFields(codeField,nameField,capitalField);
