Question

在第一页加载下，编辑模板中的下拉列表显示选择请选择值，所选值为0.但是当我更改此值时，在下一个添加新的下拉列表中显示的所选索引是上一个。它应该显示选择请为每个新项目。我已经尝试了所有可能的方法，但一切都是徒劳的。这是我的代码。

                                    </cc1:Grid>

编辑：

暂时，我通过使用 ClientSideEvents 解决了这个问题，即OnClientPopulateControls函数。我只是在我的Gridview中添加了以下行。

<ClientSideEvents OnClientPopulateControls="onClientPopulateControls"/>

function onClientPopulateControls(record,type) {            
            if (type == "add")
            {
                record.SalesPerson_ID_V3Account = "Please Select";
                record.SalesPerson_TeamType="Please Select";           
            }           
        }

但是，仍在寻找更好，更可靠的解决方案。谢谢！
