Ok. I created a small test program using the webdropdown and an html button.

using the 2 methods below. The result is the 4 items get added - somewhat- I cannot select items B or C. Onlhy A and B are highlighted as i move the mouse over. So I would say that no YOUR WEBDROPDOWN just like your WEBDATAGRID are not yet  ready to replace yoru classic controls.

Unless there is something I am missing please respond! 

Button1_onclick() {

addItem(

"AAA", "1");

addItem("BBB", "2");

addItem(

"CCC", "3");

addItem(

"DDD", "4");

}

addItem(sText, sValue) {

item.set_text(sText);

item.set_value(sValue);

combo.get_items().add(item);

}

Hello Gary.

Please download the latest service release 11.1.20111.2064. This issue is fixed in it.

Hi Gary,

 Even we want to add items in Webdropdown on client side. And also filter items using Ajax calls. But we currently have version 10.2. So do we have to update to version 11.1 if  we want to get this feature?

Thanks a lot.

Hi,

Any updates?

Hi,

I am using build 12.1. Getting the above mentioned error while trying to add second item.

Hi,

Yes it was fixed and resolved in the latest service release of 10.3 and in 11.1.20111.2064 service release for 11.1. This issue should be resolved in the newest versions of NetAdvantage. If you are still facing it please point your build and if possible attach a sample reproducing it.

Was this bug#85506 fixed. I am still getting issues while adding more than one items on client-side. The below error message is coming:

Microsoft JScript runtime error: 'this._control._callbackManager' is null or not an object
