I was not able to reproduce your issue, as I do not have enough information about your case - which event handlers do you use and how, is your grid databound and how, etc. Nevertheless I have attached my VS test pages in the RadButton_RadGrid_hide_Vb.zip archive. Could you compare your actual page with mine and try to find the difference that is causing this problem? If you still cannot resolve the problem could you try to reproduce the issue with my sample, and if it is related to our products then send it back to us, so we can inspect it locally?
What I can suggest as additional troubleshooting steps are the following:
- make sure the grid is properly databound when you make it visible. If it does not have a proper datasource it cannot show data
- if you are showing the control during an AJAX request the problem could be that it cannot register its skins (stylesheets go in the head section and it is not updated during a partial postbak). In that case you can try setting the grid's EnableAjaxSkinRendering property to true before making it visible.
All the best,
