BSLZ问问题不给分。

[alonecong]

你BS我，我没分了。真不好意思啊。。

[alonecong]

问题补充！！！
String[] value = { province_name.Text, kid.Value,area_name.Value.ToString(),area_name.Text.ToString(), province_id.Value };


想问的问题是，为什么这里的area_name.Value.ToString(),area_name.Text.ToString()

都是同一个值呢？

[alonecong]

顶起来。

[杰子]

楼主别顶了
原因：
1，没分
2，你结贴率太低
3，粘那么多代码，很麻烦的。

[LutzMark]

为什么这里的area_name.Value.ToString(),area_name.Text.ToString() 都是同一个值呢？
————————————————————
ASPxTextBox这控件的Value属性和Text属性可能是引用了同一个字段，所以同一个值很正常

[pretyboy]

太长了，重点不突出，不知想说什么问题。。

ASPxTextBox这控件的Value属性和Text属性可能是引用了同一个字段，所以同一个值很正常
-------------------------------------
哥们看好了，不是一个字段。
this.area_name.TextField = "area_name";
this.area_name.ValueField = "area_id";

之前写的联动也是这么实现的，text值和value的值可以是不一样的啊！！！！
没分就不回答了。真成。冲我分来滴，还是提高问题，帮助人。




强烈BS你。。。
