Dear,
How can you fill database data in a dropdownlist control is part of a grid for dialog editing mode to add, edit and delete?

Hi Carlos, 

Thanks for contacting Syncfusion support. 
 
We need to give EditType as Dropdown with column property and also bind DataSource to column using DataSource property of columns in Grid. Dropdown DataSource must have text and value pair. Please refer to the below code example and sample.   
 
@(Html.EJ().Grid<SyncfusionMvcApplication89.OrdersView>("FlatGrid") 
.. 
        .Columns(col => 
        { 
.. 
            col.Field("ShipCountry").HeaderText("Ship Country").EditType(EditingType.Dropdown).DataSource((List<object>)ViewBag.dropdown).Width(85).Add(); 
        })) 
 
GridFeatures.cs 
        public ActionResult GridFeatures() 
        { 
             
            ViewBag.dropdown = Get(); // here will get dropdown datasource 
            return View(); 
        } 
        public object Get() 
        { 
            var country = new NorthwindDataContext().EmployeeViews.Select(s => s.Country).Distinct().ToList(); // here we will get country data in database 
            var ShipCountry = new List<object>(); 
            foreach (var id in country) 
            { 
                ShipCountry.Add(new { value = id, text = id }); // here we will bind text and value pair 
            } 
            return ShipCountry; 
        } 
 
 
If we have misunderstood your requirement, please share more details about requirement to validate the issue at our end.

Hi Carlos, 

Query1: With the example sent, yet the description is shown. 
 
Dropdown DataSource must have text and value pair. Text will be shown in dropdown and corresponding value will be saved. Please refer to the below screenshot. 
 
 
 
If you want to show id in dropdown we suggest to give idIdRol in text(text = id.iIdRol). 
 
If we have misunderstood your requirement, please share more details about requirement to validate the issue at our end.   
 
Query2: How do to hide a column on the main screen grid 

In Grid, we have visible property to show or hide columns in grid. Please refer to the below Help document and code example. 

        .Columns(col => 
        { 
            col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).TextAlign(TextAlign.Right).Width(75).Add(); 
            col.Field("CustomerID").HeaderText("Customer ID").Width(80).Visible(false).Add(); 
            col.Field("EmployeeID").HeaderText("Employee ID").EditType(EditingType.Dropdown).DataSource((List<object>)ViewBag.dropdown).TextAlign(TextAlign.Right).Width(75).Add(); 
            col.Field("Freight").HeaderText("Freight").TextAlign(TextAlign.Right).Width(75).Format("{0:C}").Add(); 
            col.Field("ShipCountry").HeaderText("Ship Country").Width(85).Add(); 
        }))

Hello such,
What you want is to display the description on the main screen grid and when the dialog to edit or add.

With regard to the other question, you want to hide a column on the main screen grid, but if you show the dialog to edit or add.

Thank you.

Greetings.

Hi Carlos, 

We deeply regret for the inconvenience. 

We have achieved your requirement using DialogTemplate feature and ActionComplete event. While using this feature, you can edit the fields that are not bound to grid columns. To edit the records using Dialog template form, set EditMode as ‘DialogTemplate’ and specify the template id to DialogEditorTemplateID property of EditSettings. While using template, you can change the elements that are defined in the Template, to appropriate JS controls based on the column type. This can be achieved by using ActionComplete event of grid. Please refer to the below Help document, code example and sample. 



@(Html.EJ().Grid<SyncfusionMvcApplication89.OrdersView>("FlatGrid") 
.. 
                  .ClientSideEvents(eve => { eve.ActionComplete("complete"); }) 
                .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.DialogTemplate).DialogEditorTemplateID("#template"); }) 
        .Columns(col => 
        { 
           col.Field("EmployeeID").HeaderText("Employee ID").EditType(EditingType.Dropdown).Visible(false).TextAlign(TextAlign.Right).Width(75).Add();// this column will be hidden initial rendering of the grid 
        })) 
<script type="text/template" id="template"> 
    <b>Order Details</b> 
    <table cellspacing="10"> 
.. 
        <tr> 
            <td style="text-align: right;"> 
                Employee ID 
            </td> 
            <td style="text-align: left"> 
                <select id="EmployeeID" name="EmployeeID"> 
                </select> 
            </td> 
            .. 
 
   </table> 
</script> 
<script type="text/javascript"> 
 
    function complete(args) { 
        var data =   @(Html.Raw(Json.Encode(ViewBag.dropdown))); 
            if ((args.requestType == "beginedit" || args.requestType == "add") && args.model.editSettings.editMode == "dialogtemplate") { 
                $("#EmployeeID").ejDropDownList({dataSource: data, width: '116px' }); // here we will bind datasource for dropdown column 
.. 
                } 
            } 
        } 
</script>
