Error Invoking 'Configure Ajax Manager'

[Vino]

Hi ,

While configuring AJAX Manager , I selected the RadGrid1 as the Initiate for AJAX Request  and the control for Update i selected the same Rad Grid 1 .

Get an error saying  " Error Invoking 'Configure Ajax Manager' Details : Exception has been thrown by the target of an invocation   "

Unable to find the solution , kindly suggest me.

Thanks in advance!

Hi Vino,

Could you please elaborate a little bit more on your application? Pasting some code snippet for the Ajax and Grid settings will help us to further research on the error and provide more to-the-point solution.

Hello Andy,

I haven't replicate such an issue on our side. Could you please elaborate a bit more on your application and the Ajax settings you have.
It will be best if you could open a regular support ticket and send us runnable version of your application which demonstrates the error. Thus we will be able to replicate it locally and advise you further.

All the best,

Unfortuately its not posible to packahe up the app, its large over 2 data bases, and contails personal data.

This is the ajaz manager section from the ASPX page. not sure if this will help.

Hello Andy,

The provided Ajax settings look correct to me and I'm not able to isolate something obvious which may cause the issue. Could you please test the application by wrapping al those controls with regular asp UpdatePanel or RadAjaxPanel instead of using RadAjaxManager and let me know if this makes any difference.
