Hi.
I am using a webdropdown that has around 100 items in it. By default, on page-load, I want to select the first item in the list.
I am using
$find("webdropdown1").set_selectedItemIndex(0);
in client-side javascript. It is selecting the first item correctly. But when I open the dropdown, the first items does not show selection. The currently selected item should be highlighted in the dropdownlist. How to accomplish this?
For your Information, I have also tried :
$find("webdropdown1").set_selectedItemIndex(0, true);
but did not work.
Hi Nikifor,
I don't have any other browser apart from IE. I am able to reproduce the behaviour with your sample. Please find your updated sample.
I have increased the number of items in webdropdown2 to 3 by adding "Z" value as well when "2" is selected in webdropdown1.
Also, I have added the below two lines in the AJAXResponse javascript function:
var ddLength = ig_controls.WebDropDown2.get_items().getLength(); alert("Number of items in webdropdown2:" + ddLength);
to check the number of items in webdropdown2 after AJAX Response comes. It shows the old values and not the count of newly loaded items.
I want to do some processing on the new items after getting the new items in the AJAX Response. but since this is not working, I am stuck here.
Is this behavior reproducible with the sample i have attached? Because i have tested this sample with FF 14, Opera 12, IE 9 and Chrome and none of the browsers shows this behavior. All the browsers show the new loaded values with the sample
I was asking for a solution to the AJAX response problem. Whatever solution you have given will not work till the AJAX response fix is done.
Problem Description: When ItemsRequested event is called and control goes to server-side to load a webdropdown with new values and after that, when a AJAX response comes to client-side, it still shows the old items in the response. When ItemsRequested event is called again, then the AJAX response shows the previous response and that's how it is working.
Ideal behaviour: When AJAX response is handled at client-side, it should show the newly loaded items so that validations can be done on the client-side for the new items.
Please provide some temporary solution to this problem if you don't have a permanent solution now. And when we can expect a permanent solution.
Hello Sunil,Please use this temporary workaround:
function mySelector() {
var dd = ig_controls.WebDropDown2;
if (dd.get_selectedItemIndex() > -1) {
dd.get_selectedItem().unselect();
}
dd.get_items().getItem(0).select();
var vtd = dd.get_items().getItem(0).get_text()
dd.set_currentValue(vtd,
true);
dd._elements[
"Input"].value = vtd;
Just checking to know how much time it will take to solve the issue? If it is going to take weeks, then please suggest some alternate solution/workaround for this issue.
