  instead of .Url you can use .DataFunc("jsfunc") to set data and use $('#id').data('api').load() to reload it on demand, in the load method you can pass parameters .load({ params:{ x: 153 } }); or you could also set the last result .data('o').lrs and call render .data('api').render() to select certain items you just call this: $('#id').val("[123,125]").change();

  • There is my View and Script: <div id="dynamicControl"></div> <div> <input type="button" id="btnSubmit" value="Submit" /> </div> <script> $("#btnSubmit").click(function (){ $('#dynamicControl').html(@Html.Raw(str)); var selectedItems = ["First", "Second", "Third"]; $('#Mult').val(selectedItems); }); function MultLoad() { var result = []; result.push({ C: "First", K: "First" }); result.push({ C: "Second", K: "Second" }); result.push({ C: "Third", K: "Third" }); return result; } </script>

  • a button inside a form tag will also submit the form and refresh the page, not sure what are you doing there, anyway that's a different problem; you need to call change event after setting the value or call api render; $('#Mult').val(selectedItems).change();

  • Missed this in the above code: @{ var str = Json.Encode(Html.Awe().AjaxCheckboxList("Mult").Multiselect(o => o.NoSelectClose()).DataFunc("MultLoad").CssClass("form-control").ToString()); } $('#Mult').val(selectedItems).change(); works fine if there is only one item in selectedItems array but it doesnt work for more than one item. I want to display a AjaxCheckboxList with all of its values selected by default.

  • selectedItems needs to be a string like "[1,2,3,4]"; so you could call JSON.stringify(["First", "Second", "Third"]);
