I have a radComboBox containing a radTreeView for selection. It is based very strongly on one of the demos. It worked beautifully until I decided to enable/disable it in the client, based on other page events. Once the radComboBox has been disabled and re-enabled, the following lines of code in the radComboBox's OnClientDropDownOpened event handler throw an error because it can no longer find the control "rtvRights" in the item (oTreeView is undefined):

var oTreeView = sender.get_items().getItem(0).findControl("rtvRights");

var oSelectedNode = oTreeView.get_selectedNode();

As I said, this code works fine unless you disable and then enable the radComboBox using it's client-side disable/enable methods.

Possible bug with checkboxes

Hi,

Using checkboxes within a combo and Checkall turned on I find that if I press the icon to open the combo box then click elsewhere without checking any entries in the combo box it the closes the box and displays the text of the first item in the list even though it was not checked.

Having AllowCustomText="True" prevents this from happening however when using checkboxes this shouldn't be needed should it?

Regards,

Jon

ValidationSummary in dynamically loaded user control

Hi, i have a page that loads user controls, like in this demo: http://demos.telerik.com/aspnet-ajax/ajax/examples/common/loadingusercontrols/defaultcs.aspx . The User control have a form (RadListView with EditTemplate) with validator controls and a ValidatorSummary control.
The problem is, the ValidatorSummary only works with ShowSummary="True" and i need to have ShowMessageBox="True". Is it the expected behavior ? How can i get it to work?

Thanks in advance.

Clear SortExpressions from viewstate

Hi,

in CreateChildControls i add the sort expressions to the grid. Because the unique name of a column could change (because the current datasource was removed from the cache because of a timeout), I clear the SortExpressions and add the new ones. But in the DataBound event, only the old sort expressions are set but not my new ones. I think they are set because of the viewstate.
How can I prevent that the Grid overrides my new SortExpressions with them from the viewstate?

Thanks!

[Solved] Internal build checkbox issue on Chrome

Hi,

Using the latest internal build (June 26th I think), I get the checkbox looking too big in Chrome. It doesn't skin properly and also the box is oversized.... Simple to replicate... It looks fine in IE9.

Event called after "remove" button appears

I'm working with a RadAsyncUpload control and currently have a javascript function attached to OnClientValidationFailed which pops up an alert with an error message.

At the time OnClientValidationFailed fires, there is a cancel button for the file that has called it rather than the remove button once it has failed validation. Is there any event that can be captured after a file has failed and the remove button has replaced the cancel button?

[Solved] How to open DIRECTLY the custom advanced insert form

got my radscheduler working fine with objectdatasource against my sql-db.

One small drawback: When i right click to add a new appointment,
it opens a basic form. there i have to click "options" to open my advanced
form. I want my advanced form opened just after click to my "add new appoinment"
context menu item, as the basic form cannot provide all required data.

how can i achieve this?
(the less java the better :-) else please be explicit)
