ComboBoX..Items.Clear();值不在预期的范围内
//初始化收货客户集合
private void InitDealers(string CustomerSmplVch)
{
if (cbReceive.Items.Count > 0)
cbReceive.Items.Clear();
string strWhere = "";
if (!string.IsNullOrEmpty(CustomerSmplVch))
{
strWhere+=" CustomerSmplVch='"+CustomerSmplVch+"' ";
}
DataTable dt = dearBLL.GetList(strWhere);
DataRow dr = dt.NewRow();
dr["CustomerSmplVch"] = "0";
dr["DealerCodeVch"] = "0";
dr["DealerNameVch"] = "--请选择--";
dt.Rows.InsertAt(dr,0);
cbReceive.DataSource = dt.DefaultView;
cbReceive.ValueMember = "DealerCodeVch";
cbReceive.DisplayMember = "DealerNameVch";
}
给combobox赋值调用此方法后，想重新给Combobox赋值，再次调用此方法，可cbReceive.Items.Clear();报错“值不在预期的范围内。”为什么啊？请大家帮帮忙，谢谢了，在线等 combobox

错误在哪一行出现
[解决办法]

  private void InitDealers(string CustomerSmplVch) 
 
        {
            //if (cbReceive.Items.Count > 0)
            cbReceive.Items.Clear();
            cbReceive.UpdateLayOut(); //试试有没有这个方法先
            string strWhere = "";

不需要cbReceive.Items.Clear() 直接绑定
[解决办法]
cbReceive.Items.Clear(); 不要 换成 cbReceive.DataSource = null;
