Ok, I think I have come up with a solution by editing the js file for creating the combo box - you may recognise most of the script to turn in to a combo box. I have highlighted the added lines with ** ** at the beginning and end (I was trying to make it bold)
(function ($) {
$.widget("ui.combobox", {
_create: function () {
var self = this,
select = this.element.hide(),
selected = select.children(":selected"),
value = selected.val() ? selected.text() : "";
**var disabled = select.is(':disabled');**
var dropDownListID = this.element.context.id;
var input = this.input = $("
")
.insertAfter(select)
.val(value)
.autocomplete({
delay: 0,
minLength: 0,
source: function (request, response) {
var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i");
response(select.children("option").map(function () {
var text = $(this).text();
if (this.value && (!request.term || matcher.test(text)))
return {
label: text.replace(
new RegExp(
"(?![^&;]+;)(?!<[^<>]*)(" +
$.ui.autocomplete.escapeRegex(request.term) +
")(?![^<>]*>)(?![^&;]+;)", "gi"
), "
$1"),
value: text,
option: this
};
}));
},
select: function (event, ui) {
ui.item.option.selected = true;
self._trigger("selected", event, {
item: ui.item.option
}
);
__doPostBack(dropDownListID, '');
},
change: function (event, ui) {
if (!ui.item) {
var matcher = new RegExp("^" + $.ui.autocomplete.escapeRegex($(this).val()) + "$", "i"),
valid = false;
select.children("option").each(function () {
if ($(this).text().match(matcher)) {
this.selected = valid = true;
return false;
}
});
if (!valid) {
// remove invalid value, as it didn't match anything
$(this).val("");
select.val("");
input.data("autocomplete").term = "";
return false;
}
}
}
})
.addClass("ui-widget ui-widget-content ui-corner-left")
**.attr('disabled', disabled)**
.click(function () { $(this).select(); });
input.data("autocomplete")._renderItem = function (ul, item) {
return $("")
.data("item.autocomplete", item)
.append("
" + item.label + "")
.appendTo(ul);
};
this.button = $("
")
.attr("tabIndex", -1)
.attr("title", "Show All Items")
**.attr('disabled', disabled)**
.insertAfter(input)
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass("ui-corner-all")
.addClass("ui-corner-right ui-button-icon")
.click(function () {
// close if already visible
if (input.autocomplete("widget").is(":visible")) {
input.autocomplete("close");
return;
}
// work around a bug (likely same cause as #5265)
$(this).blur();
// pass empty string as value to search for, displaying all results
input.autocomplete("search", "");
input.focus();
});
},
destroy: function () {
this.input.remove();
this.button.remove();
this.element.show();
$.Widget.prototype.destroy.call(this);
}
});
})(jQuery);
