This gets me 90% of the way there but then you use "
$("#GridEmployeeID")". Where does GridEmployeeID come from? Is this something that Syncfusion creates? If so then how are we supposed to know what the drop-down-list will be named?Hi William,
"
$("#GridEmployeeID")". is the id dropdown element which is the combination of Grid id and column field name.Regards,

Hello Alan,
I tried the below code in my Razor view and i am unable to see the Dropdown values for the cloumn in the grid. can you please suggest any change to make it work.
<div id="ControlRegion">
<br />
<div>
<table style="padding-left: 200px">
<tr>
<td style="width:auto">
@(Html.EJ().Grid<UnitClassPlanTool.Models.DeptPlanLevel>("FlatGrid")
.Datasource((IEnumerable<UnitClassPlanTool.Models.DeptPlanLevel>)ViewBag.deptplans)
.EditSettings(edit => { edit.AllowEditing(); })
.ClientSideEvents(eve=>eve.ActionComplete("actionComplete"))
.Columns(col =>
{
col.Width("150px").Field("DeptID").HeaderText("Department").HeaderTextAlign(TextAlign.Center).IsPrimaryKey(true).Add();
col.Width("275px").Field("PlanLevelName").HeaderText("Plan Level").HeaderTextAlign(TextAlign.Center).EditType(EditingType.Dropdown).Add();
}))
</td>
</tr>
</table>
</div>
</div>
<script type="text/javascript">
function actionComplete(args) {
//while editing the grid
if (args.requestType == "beginedit") {
//New Dropdown data source and here text is display purpose and values is saved to data base.
var dpDataSource = [{ value: 1, text: 'WOS' }, { value: 2, text: 'TopDown' }, ];
$("#GridPlanLevelName").ejDropDownList({ dataSource: dpDataSource, selectedIndex: 1 }); //Set the new Dropdown datasource
}
}
</script>
I am not sure why the HTML tags lost. here is the scriptblock i used
<script type="text/javascript">
function actionComplete(args) {
//while editing the grid
if (args.requestType == "beginedit") {
//New Dropdown data source and here text is display purpose and values is saved to data base.
var dpDataSource = [{ value: 1, text: 'WOS' }, { value: 2, text: 'TopDown' }, ];
$("#GridPlanLevelName").ejDropDownList({ dataSource: dpDataSource, selectedIndex: 1 }); //Set the new Dropdown datasource
}
}
</script>
function actionComplete(args) {
//while editing the grid
if (args.requestType == "beginedit") {
//New Dropdown data source and here text is display purpose and values is saved to data base.
var dpDataSource = [{ value: 1, text: 'WOS' }, { value: 2, text: 'TopDown' }, ];
$("#GridPlanLevelName").ejDropDownList({ dataSource: dpDataSource, selectedIndex: 1 }); //Set the new Dropdown datasource
}
}
