[C# net 4] Load page please wait (not updating but page load)
Hi all, hope in your help and suggestions.
I need show the classic message 'Please wait' when my gridview is populated in my page aspx.
In the google search I find all examples and tutorials with buttons that update the page aspx, e.g.:
http://aspsnippets.com/Articles/Display-loading-progress-image-when-Page-Loads-or-does-PostBack-using-ASPNet.aspx
In this demo when call gridview.aspx the message not show, instead is show when click in the button 'btnSubmit'.
Can you help me?
I tried this version but the images spinner4-greenie.gif not showed:
