Clear Grid of Results

jaykapalczynski — Thu, 17 Jul 2014 19:12:31 GMT

If I am populating my grid as such how to I clear it.....when I rerun my function to get new data in a new area the last results are there untill the code finishes running....I want that to clear first before running the code.

Function updateGrid(featureSet) {

var data = arrayUtils.map(featureSet.features, function (entry, i) {

return {

id: entry.attributes.OBJECTID,

SITENAME: entry.attributes.SITENAME,

WATERBODY: entry.attributes.WATERBODY,

ACCESSAREA: entry.attributes.ACCESSAREA,

LOCATION: entry.attributes.LOCATION

};

});

// If you use a store...

dataStore = new Memory({

"data": data,

"idProperty": "id"

});

gridNoColumnSets.set("store", dataStore);

gridNoColumnSets.startup();

}

Jay,

If it is a dgrid you are talking about then you have to add an empty store to it before you go through your loop to add the new store.


function clearMyGrid()


{


     var emptyCells = { items: "" };


     var emptyStore = new dojo.data.ItemFileWriteStore({data: emptyCells});

     gridNoColumnSets.setStore(emptyStore);


}
