This is really weird - I am using html chart in an asp .net site and as of last week clients with 9.x and 10.x versions of IOS on ipad (and possibly iphone) are no longer having charts rendered on a page, everyone else is acting normally. I thought it may have come from an update where i added a radupdatepanel but have removed that and have the same problem.
I can replicate it on my old ipad but cannot debug it because of the version.
The charts are straight forward:
<telerik:RadHtmlChart runat="server" ID="chtTimeGraph" class="chartwrapper" RenderAs="Canvas" Transitions="False" EnableViewState="False">
<ClientEvents OnLoad="chartLoad" />
Have tried with viewstate enabled, without the OnLoad, different renderAs but all to no avail.
is anyone else having this problem?
