    Hello, i have insert a dropdown menu on a jqxgrid, populate by an Json query.
    An example is better than word so i capture the behavior and lay it on youtube: https://www.youtube.com/watch?v=3jI9GY-_GjI

    As you can see on my first dropdown column every time i clic on it i got the ‘please choose message’ that not appear on my second dropdown column (that’s what i want).
    Also the value is automatically change on the first clic i do (after it value stay as default, that’s what i want).

    As my english is pretty bad, please look at the video for a better idea of the problem.
    Here my cell codes for both dropdown:

    { text: ‘LISTE’, columntype: ‘dropdownlist’, datafield: ‘LISTE’, width: 200
    , initeditor: function (row, cellvalue, editor) {
    editor.jqxDropDownList({ source: dataAdapter, displayMember:”WLdescr”,valueMember: “CODE” }); }
    , cellvaluechanging: function (row, column, columntype, oldvalue, newvalue) {
    if (newvalue == “”) return oldvalue;}

    },

    { text: ‘STATUT’, columntype: ‘dropdownlist’, datafield: ‘WL_STATUS’, width: 140
    , initeditor: function (row, cellvalue, editor) {
    editor.jqxDropDownList({ source: WLstatusdata, displayMember:”DESCRIPTION”,valueMember: “CODE” });
    }
    , cellvaluechanging: function (row, column, columntype, oldvalue, newvalue) {
    if (newvalue == “”) return oldvalue;}
    },

    Hi tompasto,

    The problem I see in the provided code is that the DropDownList’s data source is updated unnecessary each time the editor is opened. To set the data source, use the “createeditor” callback. To update the selected item, use the “initeditor” callback.

    Best Regards,
