Thanks for your answer.
i have implemented as you have said. but i have String[][] for me for
countries, where i am storing (id, value)
as i am having this store.
Store gridCountriesStore = new SimpleStore(new String[]{"countryid",
"countryName"}, new String[][]);
and i am updating this store with values in "onFocus" method of
ComboBoxListenerAdapter. and i am getting values in to store as
// copied this while debugging in the eclipse.
[[1, INDIA], [2, US], [11, UK], [12, Australia], [13, England], [14,
Srilanka], [15, China], [16, West Indies], [17, Asia], [19, South
America], [24, Africa]]
i am able to see country names when i see int he dropdown. but after
selecting a particular country and tabbing out from there, immediately
id is populated in the grid cell. For Example: if i select England
from dropdown, and tabbed out from there, 13 is displayed in the cell.
so, i used the below code to solve the problem. but i am getting null
from record.getAsString("countryName");
col.setRenderer(new Renderer() {
public String render(Object value, CellMetadata
cellMetadata,Record record,
int rowIndex, int colNum, Store store) {
String name = record.getAsString("countryName");
return name;
}
});
please help me..
