求助:TextBox改变后点击 Button!希望跳过Button事件,直接刷新到PageLoad

flyin2006 2006-12-18 09:22:18

<asp:TextBox ID="txtDestinationEdition" runat="server" OnTextChanged="txtDestinationEdition_TextChanged" AutoPostBack="True"></asp:TextBox>
<asp:Button ID="btnDestinationSon" Text="选择子项" runat="server" OnClick="btnDestinationSon_Click" />

在TextBox后希望跳过其他的事件，直接让页面跳到到Page_Load事件，有没有可能？给个思路～谢谢！一个困扰一周，才想到这么憋足的解决方法！

我讲具体些!
举例:TextBox1 TextBox2
效果:当TextBox1值改变时候 TextBox2的值变成TextBox1的值

你的意思是TextChange以后，再次帮定一下数据把？那你把帮定数据拉出来，写成方法，在TextChanged事件中调用一下不就可以了吗？

去掉这个Button.
多余的.

在txtDestinationEdition_TextChanged 事件中.稠用重新显示数据的方法就可以

是这样的
在Page_Load里面绑定了数据显示!（与TextBox内容有关）
txtDestinationEdition_TextChanged ()事件

可能是我不理解:比如TextBox 后面一个不同Button
现在你在TextBox里面输入东西，然后点按钮！是不是执行Page_Load事件，然后执行txtDestinationEdition_TextChanged ()然后btnDestinationSon_Click()我想就是
在txtDestinationEdition_TextChanged ()里面执行完以后然后再次刷新页面显示数据！
而不执行点击事件，不晓得有没有讲明白？

txtDestinationEdition_TextChanged ()事件是服务器事件为什么又加documeng.form1.submit
有点晕了

目的是为了解决一个bug 其实是我程序设计的问题

比如我鼠标从TextBox离开后,然后点击Button
他会执行Page_Load 然后 txtDestinationEdition_TextChanged 然后是btnDestinationSon_Click()
我希望是　执行Page_Load 　然后执行txtDestinationEdition_TextChanged
我在txtDestinationEdition_TextChanged ()事件里面加个documeng.form1.submit实现刷新

去掉 OnTextChanged="txtDestinationEdition_TextChanged" 就可以
