Hi Team,

We have a grid with custom drop down with a list of options.

Is there any way to bind these options using MVC tag helpers?

General code (Working):

<option value="0" selected>Select</option>

<option value="1">Future Fill Date</option>

<option value="2">Transfer Rx</option>

<option value="3">Resubmit Claim</option>

<option value="5">FileOnly</option>

</select>

</div>

</script>

MVC Tag helper asp-item code (not Working):

</select>

</div>

</script>

Hi Sandhya,

Thanks for contacting Syncfusion Support.

Query#:- We have a grid with custom drop down with a list of options. Is there any way to bind these options using MVC tag helpers?

From your query, we understand that you need to used to MVC tag helpers inside the script tag used for column template featrue of ejGrid. But we cannot directly use tag Helpers inside the script Tag, because we cannot serialize the data and bind to Taghelpers under script Tag.

To overcome this problem, we have achieved your requirement using template-refresh event of the Grid. We have placed the dropdown as Template column and rendered as ejDropdown using template-refresh event of the Grid and bind dataSourcer from server end.

Refer to the code example;-

<ej-grid id="FlatGrid" allow-paging="true" datasource="ViewBag.datasource" allow-filtering="true" template-refresh="refresh">

<e-columns>

<e-column header-text="Template" template="#columnTemplate" width="75" field="EmployeeID"></e-column>

<e-column field="OrderID" header-text="Order ID" is-primary-key="true" text-align="Right" width="75"></e-column>

. . .

</e-columns>

</ej-grid>

</script>

function refresh(args) {

var data = @Html.Raw(Json.Serialize(ViewBag.datasource1))

$(args.cell).find("#dropdown" + args.rowData.EmployeeID).ejDropDownList({ width: 150, dataSource: data, fields: { text: "text", value: "value" } });

}

</script>

Serverside:-

public ActionResult Index()

{

bike.Add(new Bikes { empid = "bk1", text = "Apache RTR" });

bike.Add(new Bikes { empid = "bk2", text = "CBR 150-R" });

bike.Add(new Bikes { empid = "bk3", text = "CBZ Xtreme" });

bike.Add(new Bikes { empid = "bk4", text = "Discover" });

bike.Add(new Bikes { empid = "bk5", text = "Dazzler" });

ViewBag.datasource1 = bike;

return View();

}
