var dataStore;
var Grid;
var DataUrl;
function getGridsettings(GridsettingsUrl, DataUrl,param, method) {
DataUrl=DataUrl;
if (param == null && method == null) {
Ext.Ajax.request({
url : GridsettingsUrl,
method : 'GET',
success : onGetGridSettingsSuccess,
failure : onGetGridSettingsFailure
});
}
};
function onGetGridSettingsSuccess(result, request) {
GridSettings = result.responseText;
Intialize(GridSettings);
};
function onGetGridSettingsFailure(result, request) {
Ext.MessageBox.alert('Failed', 'GetColumns failed: ' + result.date);
};
function Intialize(gridsettings) {
var gridSettingsValues = Ext.util.JSON.decode(gridsettings);
var gridName = gridSettingsValues.title;

wow, that's really hard to read!
Yes it's possible to load data after the grid is instantiated/rendered. You need to inspect the store to see what's going on. also, does your data match the mapping (fields)?
is it possible to load data?
No.
Or, maybe it is since there's so many examples of grids with data in them. :)
I can't stand reading coding that's not properly indented, so maybe you can look at the Grid FAQ to figure out your problem. The first one should help.
can you please provide me example.
the example looks like
1. function has to return grid settings like function getgridsettins(url,params) and return json object
2. function to create the grid by taking json object and has return grid component.
3. function has to take grid and load the data.
