基于另一个列表项目填充列表项目(Populate a List Item based on another List Item)

 我们有一个用户选择部门的UI。 它进入一个List项目。 我们为每个部门分别使用SharePoint用户组。 
 
 我想在列表项目之一中填充SharePoint组中的用户。 所以现在基于选择的部门，我需要填充列表项。 
 
 请帮助我这样做。 我可以使用以下方式获取组中的所有用户： 
 
        DropDownList ddl = new DropDownList();
        ArrayList al = new ArrayList();
        SPWeb web = SPContext.Current.Web;
        SPGroupCollection grpCln = web.Groups;
        foreach (SPGroup grp in grpCln)
        {
            if (grp.Name == "Viewers")
            {
                foreach (SPUser user in grp.Users)
                {
                    al.Add(user.Name);
                }
            }
        }
        ddl.DataSource = al;
        ddl.DataBind();

We have an UI where user selects a department. It goes into a List item. We have separate SharePoint user groups for each department.
 
I want to populate the users in the SharePoint group in one of the list Item. So now based on department selected I need to populate the List Item.
 
Please help me in doing this. I am able to get all the users in a group using:
 
        DropDownList ddl = new DropDownList();
        ArrayList al = new ArrayList();
        SPWeb web = SPContext.Current.Web;
        SPGroupCollection grpCln = web.Groups;
        foreach (SPGroup grp in grpCln)
        {
            if (grp.Name == "Viewers")
            {
                foreach (SPUser user in grp.Users)
                {
                    al.Add(user.Name);
                }
            }
        }
        ddl.DataSource = al;
        ddl.DataBind();
