根据两个或多个条件将数据插入下拉列表。额外空格显示下拉列表中的所有项目由于验证工作而不考虑项目。如何删除空闲空间。代码是给定贝娄： -

private void loadUserGroup()
{
    CUsers objCUsers=new CUsers();
    ddlUserGroup.Items.Clear();
    ddlUserGroup.Items.Insert(0, new ListItem("", "0"));
    ddlUserGroup.Items.Insert(0, new ListItem("Admin", "2"));
    string suseid= User.Identity.Name;
    int iUserID = Convert.ToInt32(suseid.ToString());
    long iUserParent = objCUsers.SelectUserParent(iUserID);

    int iadID=objCUsers.SelectUserIDforAdmin(ddlUserGroup.Items[0].Text);
    if(iUserParent==0 || iUserParent==null)
    {
        ddlUserGroup.Visible = false;
        lblUserGroup.Visible = false;
    }
    else if (iUserParent == iadID)
    {
        ddlUserGroup.Visible = true;
        lblUserGroup.Visible = true;
        ddlUserGroup.Items.RemoveAt(0);

        ddlUserGroup.Items.Insert(0, new ListItem("Dealer", "4"));
        ddlUserGroup.Items.Insert(1, new ListItem("Admin", "3"));//Similar To Admin
    }
    else
    {
        long iUserGroup = objCUsers.SelectUserGroup(iUserID);
        if(iUserGroup==4)
        {
            ddlUserGroup.Items.Insert(0, new ListItem("Company", "5"));       
        }
        else if(iUserGroup==3)
        {
            ddlUserGroup.Items.Insert(0, new ListItem("Admin", "3"));
        }
        else if (iUserGroup == 5)
        {          
            ddlUserGroup.Items.Insert(0, new ListItem("Company", "5"));
        }       
    }   
}

您必须删除以下行：

ddlUserGroup.Items.Insert(0, new ListItem("", "0")); // blank line

所以新代码如下：

private void loadUserGroup()
{
    CUsers objCUsers=new CUsers();
    ddlUserGroup.Items.Clear();
    //ddlUserGroup.Items.Insert(0, new ListItem("", "0"));
    ddlUserGroup.Items.Insert(0, new ListItem("Admin", "2"));
    string suseid= User.Identity.Name;
    int iUserID = Convert.ToInt32(suseid.ToString());

DropdownList中的可用空间
