TextBox ReadOnly属性
0
[待解决问题]
TextBox ReadOnly属性设置成true以后页面刷新TextBox 的值会消失，
Enabled 属性也一样，谁有好的解决方案说一下～～多谢各位了～
问题补充：
openTab: function(link) {
var id = !link.href ? Ext.id() : link.href.replace(/[^A-Z0-9-_]/gi, '');
var tab;
var html = '<iframe id="iframe' + id + '" width="100%" src="';
if (link.href.indexOf('?') < 0) {
link.href = link.href + "?PageID=" + id + "&PageTitle=" + encodeURI(link.text.replace(/['\&''\?']/gi, ''));
}
else {
link.href = link.href + "&PageID=" + id + "&PageTitle=" + encodeURI(link.text.replace(/['\&''\?']/gi, ''));
}
//End Add
var tabTip = link.text;
if (typeof (link.tip) != 'undefined') {
tabTip += link.tip;
}
html = html + link.href;
html = html + '" height=100% name="iframe' + id + '" frameborder="0" scrolling="auto" style="border:0px none;" ></iframe>';
if (!(tab = this.getItem(id))) {
tab = new Ext.Panel({
id: id,
cls: 'preview single-preview',
title: link.text,
tabTip: tabTip,
html: html,
closable: true,
listeners: AppPortal.LinkInterceptor,
autoScroll: true,
border: true//,
});
this.add(tab);
}
this.setActiveTab(tab);
},

我估计你是这样：
程序本身的ReadOnly不是true，你用程序代码改成了true，Enable也一样。
然后，你刷新了，等于是回到了初始状态
所以，你在程序设置时，在属性中设置成ture or fasle，绝对不会如些。。。
刷新等于重新加载。。。

通过脚本控制ReadOnly或设置Attribute的ReadOnly

我估计你是用 js修改了 readonly=readonly，当postback之后，值是不会提交的，在form中所有input html，如果是disabled或者readonly，都不会post的，所以Server不会更新ViewState的值，postback之后，值就会消失。
有两种解决方法
1） 当 post 的时候，把textbox的Readonly或者Disabled 去除，如 document.forms[0].onsubmit=function(){ $("#textbox").removeAttr("readonly"); return true;}
2）在Textbox上面加focus事件，当focus到这个Texbox的时候，自动失去焦点。那么相当于readonly

纯js操作刷新之后是保存不了状态的
回楼上,readonly可以提交,disabled不会...
