grid.startup() not working for different data in the Dojo data grid
Below I have pasted a function to show the data in the datagrid based on the function call shownames('a'). DataGrid is not refreshing for different characters like shownames('b')...and so on . Or, How do I change the data in the datagrid without destroying the grid completely ?
function shownames(chr) {
require([
"dojox/grid/EnhancedGrid",
"dojo/store/Memory",
"dojo/data/ObjectStore",
"dojo/_base/xhr",
"dojo/domReady!"
], function(DataGrid, Memory, ObjectStore, xhr){
var grid, dataStore;
xhr.get({
url: "http://localhost/xampp/namedb.php?name_idx="+chr,
handleAs: "json"
}).then(function(data){
dataStore = new ObjectStore({ objectStore:new Memory({ data: data.items }) });
if(dijit.byId("namegrid")) {
grid.destroy();
} else {
grid = new dojox.grid.EnhancedGrid({
id: "namegrid",
store: dataStore,
query: { name_id: "*" },
queryOptions: {},
structure: [
{ name: "Name", field: "name", width: "25%" },
{ name: "Actual Meaning", field: "meaning", width: "50%" },
{ name: "name_id", field : "name_id", hidden: true }
]
}, "alphanames");
grid.startup();
}
/*
dojo.connect(grid, "onRowClick", grid, function(evt){
var idx = evt.rowIndex,
item = this.getItem(idx);
// get the ID attr of the selected row
var value = this.store.getValue(item, "country_name");
});
*/
});
});
}
Thanks, Raja
you should not refresh the grid the way you posted it !
First you need to initialize a grid at startup. So the grid shows you some data. Dont create a grid each time !!!! AFTER that your function has to communicate with the grid by using it's methods !
I constantly use this bulk to refresh the grid:
var grid= // CREATE GRID IN HERE
function yourFunction(id) {
var prepareQuery={};
prepareQuery["name_id"]=id; // Create a query based on id
grid._pending_requests={}; // Stop everything thats loading
grid._setQuery(prepareQuery); // Pass query to the grid
grid._refresh(true); // Refresh grid
}
It may also work with your code, but you may have to do some adaptions.
