Prevent Custom Input
The following example demonstrates how to allow only existing values in the AutoComplete widget.
<div id="example">
<div id="shipping">
<label for="countries" class="info">Choose shipping countries:</label>
<input id="countries" />
<div class="hint">Start typing the name of an European country</div>
</div>
<script>
$(document).ready(function () {
var data = [
"Albania",
"Andorra",
"Armenia",
"Austria",
"Azerbaijan",
"Belarus",
"Belgium",
"Bosnia & Herzegovina",

// Create the UI of the AutoComplete.
$("#countries").kendoAutoComplete({
dataSource: data,
filter: "startswith",
placeholder: "Select country...",
change: function() {
var found = false;
var value = this.value();
var data = this.dataSource.view();
for(var idx = 0, length = data.length; idx < length; idx++) {
if (data[idx] === value) {
found = true;
break;
}
}
if (!found) {
this.value("");
alert("Custom values are not allowed");
}
}
});
});
