Hi,

I've just upgraded to the latest version of Eo v 6.0.31.2 and now have a problem with processing with callbackpanels in a EO Dialog control.

My Dialog control has a callbackpanel around controls in both the content and footer templates (as below). Checkboxes trigger the callbackpanel in the content template to process the enable state of the accept button in the footer template. this was working in the previous version of EO. Now the code is fired but no change is made to the accept button.

Can you tell me what I need to change please.

Dialog

--- Content Template
------------Callbackpanel (groupname = feedcopy)
---------------Controls including checkboxes which are triggers

--- Footer Template
------------Callbackpanel (groupname = feedcopy)
---------------Image controls which are also the accept and cancel buttons for the Dialog

Hi,

We are not aware of any problems or changed on Callback made in 6.0.31. Can you make a test page that demonstrates the problem?

Thanks!

OK, I've created a sample page that tests this.

How do I upload it to you?

{

}
protected void cbpCommand_Execute(object sender, EO.Web.CallbackEventArgs e)
{
PopupCopy();

}

private void PopupCopy()
{

this.dlgCopy.IsModal = true;
this.dlgCopy.InitialState = EO.Web.DialogState.Visible;

Hi,

Thanks for the test code. We have looked into the issue and this does appear to be a bug. However it does appear to have always been there and does not appear to have been introduced by the new version. Nevertheless we will try to fix it as soon as possible.

Thanks!

OK thanks. If it helps it was working in version 6.0.26.2.

In the meantime do you have any idea of timescales for a fix?

This also affects other object events within the callback within a single template.

E.g A Callbackpanel containing a dropdown list and listbox exist in the content template of a dialog. The dropdown list is a trigger for the callbackpanel, to appy new list items to the listbox ona selected index change.

This scenario does NOT apply also.

Hi

Thanks for the upgrade. It has resolved the problem.

However a new problem has now arisen client side. If I try to update a Listbox during a callback in a dialog. The changes are not applied. This was working prior to the new version as i used it as a workaround while waiting for the server side fix.

From the example below you will see a that the checkbox can be updated during a client callback of the dropdown list within a dialog but not a listbox.

Here's the code (ASPX, CODEBEHIDE & SCRIPT)

Hi,

I believe that is normal. ASP.NET stores the item list in ViewState and when the page posts back, it rebuilds the list based on .aspx and ViewState, at which moment changes you made on the client side becomes irrelavent. ASP.NET controls are designed to bring certain changes on the client side back to the server ---- but only those the control specifically "brings back" to the server. For example, the selected item index for a list box, the text for a text box, etc. Any other changes you made are discarded when the page posts back.

Thanks
