OK, figured it out. Not sure, but the documentation seems to be a little misleading, it lists the following:
Editor1.SetSecurityImageGalleryPath= "~/uploads";
but here is how I got it to work:
protected void FormView1_PreRender(object sender, EventArgs e)
{
try
{
string theUser= ....some code
............... some code
CuteEditor.
Editor editor1 = (CuteEditor.Editor)(FormView1.FindControl("MyAnswerTextBox"));
if (editor1 != null)
{
string securityPath = Server.MapPath(MyPath + theUser + @"/MyPics");
.... some code
editor1.SetSecurityImageGalleryPath(securityPath);
... some code
Thanks,
