如何禁用treeview aoutopostback [英] how do I disable treeview aoutopostback

问题描述

我在masterpage中有一个树视图。根据选择的节点，变量传递给页面并基于此变量，页面内容被更改。但是选择一个节点，主页是重新加载，树视图显示在第一个状态。

如何禁用树视图的后视图？

解决方案

< blockquote>我们可以将'NavigateUrl'设置为值'javascript：void（0）'以避免回发如下： -

 <   asp：treenode     text   = 项目1.1    navigateurl   =  javascript：void（0）    xmlns：asp   = ＃unknown >  <   / asp：treenode  >  

但不确定您是否正在处理其点击以将变量的值传递给页面，这也可能会受到影响。在这种情况下，您可以使用将值设置为隐藏字段并可以使用它。



希望这将有助于继续进行。

如果您需要任何进一步的帮助，请告诉我。

I have a treeview in masterpage.according to what node is selected, a variable pass to a page and based this variable ,the content of page is changed. but whit select of a node, the masterpage is reload and treeview shown in first state.
how do I disable aoutopostback of a treeview?

解决方案

We can set 'NavigateUrl' to value 'javascript:void(0)' to avoid the postback as below :-

<asp:treenode text="Item 1.1" navigateurl="javascript:void(0)" xmlns:asp="#unknown"></asp:treenode>

But not sure if you are handling its click to pass the value for the variable to page, which also might be affected. In this case you can use to set value to hidden field and can use it.

Hope this will be of help to proceed further.
