Asked On September 2, 2019 04:28 PM UTC

Good morning gentlemen,

I'm trying to put a dropdownlist inside a Grid (which is easy to do), the thing is that in this dropdown I need to put the elements in a specific order different than the alphabetical, can you help me please with this one?

The column for the dropdown is "Parentezco", and "Orden" is a field of the table that I'm trying to use to order the ViewBag content

In advance, thanks!



/////////MY GRID IN THE VIEW/////////////////////

<ejs-grid id="DetalleFormatoAltaGmmVidaApGrid" dataBound="dataBound" locale="es-MX" query="new ej.data.Query().addParams('FormatoID', '@Model.FormatoID')" toolbar="@(new List<string>() { "Cancel", "Update", "Add", "Delete" })">
        <e-data-manager id="dataManager" adaptor="UrlAdaptor" url="/Sistema/Formatos/DetalleFormatoAltaGmmVidaApGrid_Read/" crudUrl="/Sistema/Formatos/BeneficiariosAccidentesPersonalesGrupalGrid_CRUD" requestType="Post"></e-data-manager>
        <e-grid-editSettings allowDeleting="true" allowEditing="true" allowAdding="true" mode="Normal" showDeleteConfirmDialog="true"></e-grid-editSettings>
        <e-grid-columns>
            <e-grid-column field="DetalleID" isPrimaryKey="true" isIdentity="true" visible="false"></e-grid-column>
            
            <e-grid-column field="Parentezco" headerText="Parentezco" foreignKeyField="TipoParentezco" foreignKeyValue="Descripcion" dataSource="@ViewBag.TiposParentezco"></e-grid-column>

            
        </e-grid-columns>
    </ejs-grid>

///////////////////CONTROLLER SIDE///////////////////

ViewBag.TiposParentezco = _context.TiposParentezco.OrderBy(p => p.Orden).ToList();

Hi Javier, 
 
Greetings from Syncfusion support. 
 
For this scenario, you can use our sortOrder property of DropdownList component to achieve it. Could you please check the below code block and sample? 
 
<ejs-grid id="Grid" dataSource="@ViewBag.datasource" height="315" allowPaging="true" toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Update", "Cancel" })"> 
    <e-grid-editSettings allowAdding="true" allowDeleting="true" allowEditing="true"></e-grid-editSettings> 
    <e-grid-columns> 
        <e-grid-column field="OrderID" headerText="Order ID" isPrimaryKey="true" textAlign="Right" width="100"></e-grid-column> 
        <e-grid-column field="CustomerID" headerText="Customer ID" edit="@(new {create = "create", read = "read", destroy = "destroy", write = "write"})" type="string" width="120"></e-grid-column> 
 
        <e-grid-column field="Freight" headerText="Freight" textAlign="Right" format="C2" editType="numericedit" width="120"></e-grid-column> 
        <e-grid-column field="ShipCountry" headerText="Ship Country" width="150"></e-grid-column> 
    </e-grid-columns> 
</ejs-grid> 
 
<script> 
    var elem; 
    var drpObj; 
    function create(args) { 
        elem = document.createElement('input'); 
        return elem; 
    } 
 
    function write(args) { 
        var grid = document.getElementById('Grid')["ej2_instances"][0]; 
        var data = grid.dataSource; 
        drpObj = new ej.dropdowns.DropDownList({ 
            value: args.rowData[args.column.field], 
            dataSource: data, 
            fields: { text: 'CustomerID', value: 'CustomerID' }, 
            sortOrder: 'None' 
        }); 
        drpObj.appendTo(elem); 
    } 
 
    function destroy() { 
        drpObj.destroy(); 
    } 
 
    function read(args) { 
        return drpObj.value; 
    } 
</script> 
 
 
 
 
Please check the sample and get back to us, if you require any further assistance on this. 
 
Regards, 
Ashokkumar B.
