I have a grid, inside of some column of which I have created a combobox editing UI, using columns.editor function. My goal is every time a user selects some value from the combobox -while populating a newly created grid record-, this value to be removed from the list options of a next record's combobox.
One of the things i've tried is shown below:
function equipmentDropDownEditor(container, options) {
var equipmentComboBox = $('<input id="equipmentDropDownEditor" required data-text-field="name" data-value-field="name" data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoComboBox({
autoBind: false,
dataSource: equipmentTypesDS,
dataBound: function(e) {
var equipmentData = e.sender.dataSource.data();
if(currentlyInsertedEquipmentTypes.length > 0){
for(var i=0;i<currentlyInsertedEquipmentTypes.length;i++){
$.each( equipmentData, function( index, selectedEquipmentData ) {
if (selectedEquipmentData.name == currentlyInsertedEquipmentTypes[i]){
var dataItem = e.sender.dataSource.at(index);
console.log("dataItem: " + dataItem.name + " is being removed");
e.sender.dataSource.remove(dataItem);
}
});
}
}
}
});
}
I've created a global array variable named "currentlyInsertedEquipmentTypes" inside of which I hold all the user's already selected values (for example if the user has created 2 records inside the grid and has selected "laptop" option in the combobox of the first and "workstation" option in the combobox of the second --> currentlyInsertedEquipmentTypes = ["laptop", "workstation"] ).
Inside the combobox dataBound event I check whether the user has already selected values (currentlyInsertedEquipmentTypes.length>0) and if he has, I locate the corresponding object inside the bound dataSource and I remove it, so that it wont be available in the next record's combobox list. This is where the whole thing crashes even though the data item removal takes place.
Am i missing something that i should do after the data item removal? Should i rebind the datasource to the combobox in some way? Any help would be much appreciated.
[EDIT]
---- The combobox datasource code
var equipmentTypesDS= new kendo.data.DataSource({
transport: {
read: {
url: "api/equipment_types",
type: "GET",
data: {
//"equipment_category": 1
},
dataType: "json"
}
},
schema: {
data: "data",
total: "total"
}
});
--- the kendo grid code:
$("#popup_equipment").kendoGrid({
dataSource: {
schema:{
model:{
id: "equipment_type_id",
fields:{
equipment_type_id: { editable: false },
name: { }, //validation: {required: true}, defaultValue: "LAPTOP",
items:{ type: "number", defaultValue:1, validation: { required: true, min: 1} }
}
}
}
},
toolbar: ["create"],
columns: [
{ field: "name", title: "εξοπλισμός", width: "300px", editor: equipmentDropDownEditor, template: "#=name#" },
{ field: "items", title:"πλήθος", width: "80px"},
{ command: ["destroy"], title: " ", width: "100px" }
],
//editable: "inline",//true,
editable:{confirmation: false},
scrollable: false,
selectable: false
});
