Upload gets to 99% never hits 100% and does not close.

[Wired_Nerve]

I have a radgrid where I am exporting to Excel.
The RadprogressBarArea increments just fine to 99 percent then stops. (CommandItemTemplate imagebutton click event fires the export process)
After a moment the open,save or cancel window opens for the excel export process..
I save save it or etc...
The progress area never goes away.
Someone suggested reloading the page (not an option).
I have looked at various java script options and other forum post,  but I am having problems following them.

Anyone else run across this and know of a good link?

Hi Warren,

Please try setting progress.OperationComplete = true in the UpdateProgressContext method. Does the issue persist?

Kind regards,

this does not help! :(

Hello Warren,

Is the whole content place holder ajaxified by RadAjaxManager or wrapped inside RadAjaxPanel? Does the issue persist If you disable Ajax?

All the best,
