I can send you a sample project that reproduces a bug related to RadTimePicker we haven't been able to solve so far. I wasn't able to issue a support ticket although we have licensed copy of RadControls for Ajax and Report. Please let me know how you'd like to get the sample project.
In that sample .NET 3.5 web application project, WebForm1.aspx is a start page. It has 2 panels. First panel is visible and second one is invisible.
Panel 1 has a "Show Time Picker" button that when clicked toggles both panel's visibility. I.e. it switches to panel 2.
Panel 2 has a RadTimePicker and a Back button.
Back button's OnClickClick opens a RadWindow which shows another page called ConfirmBox.aspx.
On confirming Yes, a JS function is called that calls WebForm1's (parent's) callback JS function.
The callback function does a __postback indicating that BackButton is clicked.
In the codebehind PageLoad method if BackButtonClicked flag is set then the Panel 1 is visible.
Once you get the sample project, you can reproduce the problem with these steps:
- Click Show Time Picker in Panel 1.
- Panel 2 is shown.
- Click Back button on Panel 2.
- Confirmation box appears.
- Click Yes.
- Panel 1 is shown again.
- Click Show Time Picker button again.
- Now the Panel would be displayed with RadTimePicker not rendered at all in IE, Firefox, Chrome, Safari.
See attached screen showing the problem with RadTimePicker. The problem happens only when RadAjaxManager or RadAjaxPanel are used. We want to show progress indicator so we want to use RadAjaxManager or RadAjaxPanel but we're now stuck.
