[转]如何在数据绑定时不让combox控件触发SelectedIndexChanged事件

    this.cboVendor.SelectedIndexChanged -= new System.EventHandler(this.cboVendor_SelectedIndexChanged);                     cboVendor.DataSource =  myClass.RunQueryCmd(strSqlCmd); 
           cboVendor.DisplayMember = "SupplierCode"; 
            //添加事件
         this.cboVendor.SelectedIndexChanged += new System.EventHandler(this.cboVendor_SelectedIndexChanged);
