AjaxLoadingPanel during Export process?

[Brian Dobberteen]

Hi,

I have a RadGrid control that I am exporting to CSV.  Everything works great, except I cannot figure out a way to make an AjaxLoadingPanel appear while waiting for the export process to complete.  In other words, there is a few seconds delay after hitting 'export' and the file download dialog box appearing - during this delay there is no visual feedback to the user.

Is this even possible?

Thanks!

Hello Brian,

One suggestion is to use "RadProgressArea" instead of RadAjaxLoadingPanel as described in following forum.
Display Loading Panel during Export

Please download the sample project attached in the forum thread and see whether it suits for your need.

Wow, I can't believe I missed that thread!

Thank you so much for your assistance!

Maybe my exuberance was a bit premature... The method suggested works, but not very well...

First, the progress indicator appears when the grid is first databound, prior to any attempts to export the data.  It only briefly appears, but I don't want to see it unless I am actually doing an export.

Second, when doing the export, the progress area exhibits inconsistent behavior... it doesn't always display, and when it does, it shows a different 'item count' than the time before.  On top of that, it never disappears, which is not at all what I want.

Ideally, again, I'd like to simply display an AjaxLoadingPanel during the export, but will settle for using the ProgressArea if need be...

Any and all assistance is greatly appreciated!

Thank you!

Hello Brian,

All "progress indicators" suffer from a common issue when exporting - there is no easy way to hide them. First, it is hard to determine whether the file has been transferred to the client. Second, all changes made after the file has been exported will affect the output file only - this means that even if you hide the loadingpanel / progressarea / etc this setting won't have an effect on your real page.
One of the workarounds would be to force the user to press a CLOSE / FINISH button to refresh the page.

I assume there's still no proper solution to hiding the ajaxpanel after the export has finished ?

you mentioned a close button, have you got a code library project with this demonstrated ? or could you describe hte implementation ?

still playing with this;

ideally it would be nice to use the radconfirm to popup when the export has finished, with a button that refreshes the page.
