That's OK Martin,

Thank you very much for your help!!!

Hello Flavio,

ColumnUpdatingComboEditorOptions class doesn't have a property for setting "ID" of the combo. And there is no other way to set it in this class. The workaround as you suggested is to use a ColumnUpdatingSetting.EditorOptions property which is a string property. You can set the dataSource by serializing the List<Customer> using the System.Web.Script.Serialization.JavaSctiptSerializer class.

Here is an example code:

ColumnUpdatingSetting productSetting = new ColumnUpdatingSetting();

productSetting.ColumnKey = "ProductID";

JavaScriptSerializer serializer = new JavaScriptSerializer();

productSetting.EditorOptions = String.Format("id: 'myCustomId', valueKey: 'ProductID', textKey: 'Name', dataSource: {0}", serializer.Serialize(GetProducts()));

Hope this helps,

Ok Martin, I solved ;-)

As you suggested I saw that example and I copy the idea that combo editor is not generated at a very first time.
So what I did?

1. I extract the combo dataSource on the igGridRendered event, just looking for the exactly column:
           var updating = $("#grid1").data("igGridUpdating");
           var colSettings = updating.options.columnSettings;
   datasource = colSettings[2].editorOptions.dataSource;
2. In this way I am able to call my custom function mapCustomer(id) directly from FormatterFunction of the interested column

As you can see, my big problem was "how to catch the igCombo dataSource". With the bold sentence it is perfectly done.

However, it would be interesting to know how to set ID directly from controller or to pass datasource directly from controller to the GridModel by editorOptions...

Thanks

Hi Martin,

thank you very much for your answer.

You're right, but in that sample combo ID is assigned by cshtmlView side. In my case I need to set it byController side, and I am not able to find that option...

ColumnUpdatingComboEditorOptions updatingComboEditorOptions = new ColumnUpdatingComboEditorOptions();
            updatingComboEditorOptions.DataSource = customers.AsQueryable();
            updatingComboEditorOptions.DropDownOnFocus = true;
            updatingComboEditorOptions.ShowDropDownButton = false;
            updatingComboEditorOptions.ValueKey = "CustomerId";
            updatingComboEditorOptions.TextKey = "CustomerName";
            updatingComboEditorOptions.FilteringType = ComboFilteringType.Local;
            updatingComboEditorOptions.ID = ...

For sure I could try in this way:

ColumnUpdatingSetting uSetCustomer = new ColumnUpdatingSetting();
uSetCustomer .EditorOptions = "id: 'combo_fornitori'" +
                                            ",dataSource: ???"
                                            ",valueKey: 'IdFornitore'" +
                                            ",textKey: 'RagioneSocialeFornitore'" +
                                            ",dropDownOnFocus : true" +
                                            ",showDropDownButton : false" +
                                            ",filteringType : 'local'";

But what about datasource? What have I to specify for it? Take in account that I have a List<Customer> list by controller side that I can set AsQueryable... But I really don't know how to set it in my action GridModel creation...

Thanks

Flavio
