i see the table in tablesystem and i add new field... but i can see the custom fields in cmsdesk--->project
i finde list.xml and add this code:
<column source="email" caption="ایمیل" wrap="false" externalsourcename="email" />
and add this line code in list.ascx
protected object gridElem_OnExternalDataBound(object sender, string sourceName, object parameter)
{
DataRowView row = null;
switch (sourceName.ToLower())
{
case "email":
string email = ValidationHelper.GetString(((DataRowView)((GridViewRow)parameter).DataItem).Row["email"], "");
return HTMLHelper.HTMLEncode(email);
