virtualScrollMode enum
The Virtual Scrolling feature is used to display a large amount of records in the DropDownList, that is, when scrolling, an AJAX request is sent to fetch some amount of data from the server dynamically. To achieve this scenario with DropDownList, set the allowVirtualScrolling to true. You can set the itemsCount property that represents the number of items to be fetched from the server on every AJAX request.
This property enables the data to load dynamically in two ways.
Name | Description |
---|---|
normal | The data is loaded only to the corresponding page (display items). When scrolling some other position, it enables the load on demand with the DropDownList. |
continuous | The data items are loaded from the remote when scroll handle reaches the end of the scrollbar like infinity scrolling. |
Default Value
- “normal”
Example - Normal mode
<input type="text" id="dropdown" />
<script>
var dataManagerObj = ej.DataManager({ url: "http://mvc.syncfusion.com/services/Northwnd.svc/Orders" })
var query = ej.Query().select("ShipName", "ShipCountry");
// Creates DropDownList.
$('#dropdown').ejDropDownList(
{
dataSource: dataManagerObj,
query: query,
fields: { text: "ShipName", value: "ShipCountry" },
itemsCount: 20,
allowVirtualScrolling: true
});
</script>
Example - Continuous mode
<input type="text" id="dropdown" />
<script>
var dataManagerObj = ej.DataManager({ url: "http://mvc.syncfusion.com/services/Northwnd.svc/Orders" })
var query = ej.Query().select("ShipName", "ShipCountry");
// Creates DropDownList.
$('#dropdown').ejDropDownList(
{
dataSource: dataManagerObj,

itemsCount: 20,
allowVirtualScrolling: true,
virtualScrollMode: "continuous"
