Filter out Duplicates

[binfchParticipant]

Hi there

I have a combobox with:

var srcCompany = { datatype: "array", localdata: CompanyDataArray };
var datCompany = new $.jqx.dataAdapter(srcCompany);
$("#cmbImpCompany").jqxComboBox({ source: datCompany, displayMember: "CompanyName", valueMember: "CompanyId" });

The CompanyDataArray contains many fields. For the combobox I just need “CompanyName” and “CompanyId”. This code works but with dupplicates

-> What would be the recomended way to avoid dupplicates?

Thx & cheers,
P.

Hi binfch,

You can specify an unique DataField to the DataAdapter. This will filter out the duplicate records.

                var dataAdapter = new $.jqx.dataAdapter(source, {
                    autoBind: false,
                    async: false,
                    uniqueDataFields: ["ContactTitle"]
                   }                             
                );

Hi Peter

Thanks for the info -> This works great but I have another question.

The “source” data array looks like:

Right now I filter/extract (in a separate/new array) the 2 columns “DepartmentId” and “DepartmentName” for “CompanyId = 3” before using/assigning these in a jqxComboBox.

This process takes some time and I was wondering if there is a more performant/better way to directly use the “source” data array in the jqxComboBox (without passing through the mentioned extra step)?

Thanks & cheers,
Peter

Hi Peter,

I am afraid that there’s no built-in filtering in the jqxDataAdapter. It is only possible to filter the duplicate records by using a code like in my previous post.
