We suspect a bug of Telerik controls:
Bug of Telerik: PageView.set_contentUrl(MyUrl) method - call MyUrl twice if RadTabStrip and RadMultiPage is inside RadAjaxPanel control. Firefox only.
Code: http://bit.ly/2NVbm8Z
It enter here two times: http://bit.ly/2NZ0cQH
If try it in chrome - request goes only one time.
If remove RadAjaxPanel - also request goes only one time.
Is it bug of your Controls?
Hi Steve,
Using the attached code sample, I was unable to reproduce this issue. For your reference, I have included a video with the attached sample displaying the expected behavior.
Can you confirm the Base Class titled BasePage isn't forcing a second AJAX Request?
Please let me know the results of the BasePage investigation. Thank you and I look forward to your reply.
