Using WebCombo 3.0.3000.18 with VS.Net 2003 on Windows XP with Internet Explorer 7

We are "suddenly" experiencing problems with postback when debugging our solutions locally using VS.Net 2003. It also happens when we use the locahost-site without using Vs.Net, i.e. simply typing in http : // localhost/mysite/... in Internet Explorer.

We have a setup where we use two WebCombos and making a selection in the first webcombo triggers the other webcombo and it retrieves the data based on the selection of the first.

When a value is selected in the first WebCombo, a Postback orrurs and we get the Javascript error: "An object was expected". The problem occurs in the file ISCore.js and according to VS.Net in the Javascript fragment

var v23740 =window.event.srcElement.id

What is really weird is that we do not have these problems in our test/production environment where we also use Internet Explorer 7 and Windows XP (but not locally).

Do you guys have an idea of what we might be doing wrong?

Thanks,

Jesper

My own addition:

We just confimed that the problem does not exist when accessing the site at localhost using Firefox (3.0).

Any help is still highly appreciated.

Thanks,

Jesper

I have a page with WebCombo controls that use MultipleSelection. I want to reset the selection on reset button. I'm using foloowing javascript.
var wcEmployee = ISGetObject('wcEmployee');
wcEmployee.ClearSelection();
Currently the textbox is cleared but if the user opens the webcombo, the items are still selected inside. How do I clear the multiple selections?

I have a page with WebCombo controls that use MultipleSelection. On that page I have a clear button which should clear the webcombo's value completely. Below is part of the code which is contained in the aspx.vb file. The function is called when a user clicks the clear button.

var wcEmployee = ISGetObject('wcEmployee');
wcEmployee.ClearSelection();

Currently the textbox is cleared but if the user opens the webcombo, the items are still selected inside. How do I clear the multiple selections?

I left a less than favorable review of this control for many reasons. I guess componentsource only shows favorable reviews for their products. IMO, they should remove the review function if they won't allow an intelligently written yet critical review of a product come to light. I wasted hours and hours on this control, and felt it would be good to share news of this with my colleagues. I guess componentsource doesn't want my business!

David,

I'm with you. We have had an unbelievable time getting tech support for this product. These guys just ignore you for days at a time, in some cases just never answering. I wrote a less than stellar review as well, we'll see if it gets posted.

David - To the best of my knowledge your review was posted shortly after you submitted it.

I just got the control and am in the process of implementing into my application. Very nice, except????
I can't figure out how to prepopulate the control (unbound mode)with some text that may not be in the collection of rows. Can you help? I think I can add a row
with the text in it and make it the selected row, but that sounds pretty clunky. There should be an easier way, no? The problem is that the Text property is read only.

Please get back soon, I am on deadline.

John
