Hi,
did not install the .NET components so a reference is missing.
However, I managed to reproduce in one of your online examples:
Visit http://js.syncfusion.com/demos/web/#!/bootstrap/grid/editing/inlineonlocaldata
Go to edit to open in jsplayground
Overwrite the grid data with this value:
window.gridData=[{OrderID:10248,CustomerID:"VINET",EmployeeID:5,OrderDate:new Date(8364186e5),ShipName:null,ShipCity:"Reims",ShipAddress:"59 rue de l'Abbaye",ShipRegion:null,ShipPostalCode:"51100",ShipCountry:"France",Freight:32.38,Verified:!0},{OrderID:10249,CustomerID:"TOMSP",EmployeeID:6,OrderDate:new Date(836505e6),ShipName:"Toms Spezialitäten",ShipCity:"Münster",ShipAddress:"Luisenstr. 48",ShipRegion:null,ShipPostalCode:"44087",ShipCountry:"Germany",Freight:11.61,Verified:!1},{OrderID:10250,CustomerID:"HANAR",EmployeeID:4,OrderDate:new Date(8367642e5),ShipName:"Hanari Carnes",ShipCity:"Rio de Janeiro",ShipAddress:"Rua do Paço, 67",ShipRegion:"RJ",ShipPostalCode:"05454-876",ShipCountry:"Brazil",Freight:65.83,Verified:!0}];
and place just before the grid function.
You will get this code:
...
...
<script type="text/javascript">
window.gridData=[{OrderID:10248,CustomerID:"VINET",EmployeeID:5,OrderDate:new Date(8364186e5),ShipName:null,ShipCity:"Reims",ShipAddress:"59 rue de l'Abbaye",ShipRegion:null,ShipPostalCode:"51100",ShipCountry:"France",Freight:32.38,Verified:!0},{OrderID:10249,CustomerID:"TOMSP",EmployeeID:6,OrderDate:new Date(836505e6),ShipName:"Toms Spezialitäten",ShipCity:"Münster",ShipAddress:"Luisenstr. 48",ShipRegion:null,ShipPostalCode:"44087",ShipCountry:"Germany",Freight:11.61,Verified:!1},{OrderID:10250,CustomerID:"HANAR",EmployeeID:4,OrderDate:new Date(8367642e5),ShipName:"Hanari Carnes",ShipCity:"Rio de Janeiro",ShipAddress:"Rua do Paço, 67",ShipRegion:"RJ",ShipPostalCode:"05454-876",ShipCountry:"Brazil",Freight:65.83,Verified:!0}];
$(function () {
$("#Grid").ejGrid({
...
...
After that run the example. The Ship Name of the first item is empty. If you edit it and click save the field will stay empty, the modification will not be saved!
