i have an application page called from a webpart with SP.UI.ModalDialog.showModalDialog()
On this page i've an spgridview, 2 textbox for choosing date between and a button. When i click on the button i refresh the grid depending of the date choosed.
I'd like when i click on the button, display "load in progress" till the grid is loaded. Do you know an easy solution to do this? (for information i'm already in a modaldialog and i want displaying this wait message inside)
i tried SP.UI.ModalDialog.showWaitScreenWithNoClose without success because i've an exception on my function that is null or undefined
