Save updates to a datagrid?

ionarawilson1 — Thu, 12 Dec 2013 20:01:28 GMT

Can anybody show me how to delete and save updates to a datagrid? If not to delete, at least to update the edits will help. Here is my code with two buttons, one to delete and one to save the record. Thanks

Hi Ionara,

Sorry I don't have many times to use your example. But I can give you a short sample to save updates.

function saveUpdatesFromDG():void{  var updates:Array = [];  for(var iRow:Number = 0; iRow<dgDataProvider.length; iRow ++)  {   var attributes:Object = {};   for (var id:String in dgDataProvider.getItemAt(iRow))   {          attributes[id] = dgDataProvider.getItemAt(iRow)[id];   }   var feature:Graphic = new Graphic(null, null, attributes);   updates.push(feature);  }  featureLayer.applyEdits(null,updates,null); }

I hope it helps

Thank you Ben. I just have a quick question and I'll leave you alone, I promise 🙂 Do you think you can answer the question in the post below? I actually got that search to work, where the records in the table appear according to a search but the feature layer needs to be created pro grammatically. Thank you so much!!!
