Hi, @mrthanhkhoi  Multi-Select Selector is possible.

Can you please share your code here?

Have you added this in the .aspx page? 

<px:PXMultiSelector runat="server" DataField="Ledger" ID="CstPXSelector4" CommitChanges="True" ></px:PXMultiSelector>

Hi @Naveen Boga,

thank you for your answer. It works for me.

By the way, I create a multiple selector in order to filter list ReplenishmentItem by this selector instead of Warehouse (single selector)

Which part should I modify to change filter by new multiple selector?

@mrthanhkhoi 

I’m glad that I helped you on getting the Multi-Select selector field.

You need to check the view delegate and modify the logic accordingly to fetch the selected multiple warehouses’ details and populate in the grid.

Hi @Naveen Boga 

I have modified the view as following code but it doesn’t work. I guess there is an issue with condition Where<INReplenishmentItem.siteID, In<Current<INReplenishmentFilterExt.usrWarehouse»

I tried with Where<Current<INReplenishmentFilterExt.usrWarehouse>, Contains<INReplenishmentItem.siteID> but it does not work too :(

Could you please have a look and and instruct me?

        public abstract class usrWarehouse : PX.Data.BQL.BqlString.Field<usrWarehouse> { }
        #endregion
    }
