I thik I've found the solution. It was quite simple and it seem to work !
function
CuteWebUI_AjaxUploader_OnSelect(files) {
var submitbutton = document.getElementById('<%=SubmitButton.ClientID %>');
submitbutton.style.display =
'';
}
function
CuteWebUI_AjaxUploader_OnInitialize() {
var submitbutton = document.getElementById('<%=SubmitButton.ClientID %>');
submitbutton.style.display =
'None';
}
function
CuteWebUI_AjaxUploader_OnStart() {
var submitbutton = document.getElementById('<%=SubmitButton.ClientID %>');
submitbutton.style.display =
'None';
}
