在上一篇《EXT.NET高效开发（一）——概述》中，大致的介绍了一下EXT.NET。那么本篇就要继续完成未完成的事业了。说到高效开发，那就是八仙过海各显神通。比如使用代码生成器，这点大家可以参考我的这篇帖子《CodeSmith系列（三）——使用CodeSmith生成ASP.NET页面》。本人是比较推崇批量化生产的。当然，本篇的重点不在这，看过标题的人都知道。
在使用EXT.NET的时候（当然不仅仅是EXT.NET），总是要做很多重复的事，于是封装一些实用的函数可以一劳永逸呀。
1）单选框和复选框.
看图说话开始了，如图
当选择其他的时候，出框框填写数据。在实际需求中，很多选择项都不是只有A、B、C、D，往往还能自己自定义。遇到这种需求的，每次加个框框跟后面既麻烦又不方便布局，于是秉着不重复造轮子的原则，定义了以下函数：

这样调用起来就方便了，如：

ExtControlHelper.BindCheckGroup(
this
, _db.SelectGeneralFromTableINFO(ShopID, CurrentFormID,
"TerminationReason"
).ToList()
,
"cblTerminationReason"
,
"AttributeValue"
,
"AttributeID"
,
"CheckValue"
,
4,
"其他"
, 8);

不过别忘了在页面上丢一个“<ext:Hidden ID="cblTerminationReasonHidden" runat="server" />”。
为了方便，本人又定义了以下几个函数：

2）下拉列表。

绑定下拉列表，在这里，本人也封装了以下。如下面代码：

public
static
void
BindComobox<T>(Control _userControl, List<T> lst,
string
ID,
string
TextPropertyName,
string
ValuePropertyName,
string
_SelectValue)
{
if
(lst !=
null
&& lst.Count > 0)
{
ComboBox _cbos = _userControl.FindControl(ID)
as
ComboBox;
if
(_cbos ==
null
)
return
;
_cbos.Items.Clear();
foreach
(
var
item
in
lst)
{
T t = item;
Type type = t.GetType();
ListItem _li =
new
ListItem();
//文本属性
PropertyInfo TextProInfo = type.GetProperty(TextPropertyName);
if
(TextProInfo ==
null
)
ExtensionMethods.ThrowNullException(type, TextPropertyName);
//值属性
PropertyInfo ValueProInfo = type.GetProperty(ValuePropertyName);
if
(ValueProInfo ==
null
)
ExtensionMethods.ThrowNullException(type, ValuePropertyName);
object
objText = TextProInfo.GetValue(t,
null
);
_li.Text = objText ==
null
?
string
.Empty : objText.ToString();
object
objValue = ValueProInfo.GetValue(t,
null
).ToString();
_li.Value = objValue ==
null
?
string
.Empty : objValue.ToString();
_cbos.Items.Add(_li);
}
if
(!
string
.IsNullOrEmpty(_SelectValue))
_cbos.SelectedItem.Value = _SelectValue;
}
}
|
其实还有一种方式可以绑定，但是本人更喜欢这种。比如通过Store：
|
1
2
3
4
5
|
_store =
new
Store { ID =
string
.Format(
"_store{0}"
, Guid.NewGuid().ToString(
"N"
)), IDMode = IDMode.Static };
_jsonReader =
new
JsonReader();
_jsonReader.Fields.Add(
new
RecordField(
"text"
, RecordFieldType.String));
_jsonReader.Fields.Add(
new
RecordField(
"value"
, RecordFieldType.String));
_store.Reader.Add(_jsonReader);
|
然后再加上自己定义的URL和参数，定义几个参数，封装一下，也可以通用，这里我就不继续写下去了。
3）SharePoint中，给EXT.NET赋权。
这段代码，提供给需要的人吧。当初这问题把我折磨得快疯狂了。还好想到了这么一个解决方案。

上面的代码进行了可为空类型的判断，这点需要注意。
5）设置通用的表单验证脚本。

该出图的时候还是得出图啊。

首先需要验证的表单页面得挂上这段JS：
|

7
8
9
10
11

var
valCss =
''
;
function
showMsg(title, content, cs) {
if
(valCss != cs) {
valCss = cs;
Ext.net.Notification.show({
hideFx: {
fxName:
'switchOff'
,
args: [{}]
},
showFx: {
args: [
'C3DAF9'
,
1,
{
duration: 2.0
}
],
fxName:
'frame'
},
iconCls: cs,
closeVisible:
true
,
html: content,
title: title +
' '
+
new
Date().format(
'g:i:s A'
)
});
}
}

然后：

if
(!
string
.IsNullOrEmpty(_fp.Listeners.ClientValidation.Handler))
return
;
_fp.Listeners.ClientValidation.Handler =
@"
var isCheckd=valid;var msgs;var msg='';
if(typeof(ValCustomValidator)=='function')
{
msgs=ValCustomValidator(false,valid);
if(typeof(msgs.IsVal)!='undefined')
{
isCheckd=msgs.IsVal;

msg='<span style=\'color:red;\'>'+msgs.Message+'</span>';
}
else
isCheckd=msgs;
}
if(typeof(#{btnSave})!='undefined' && #{btnSave}!=null)#{btnSave}.setDisabled(!isCheckd);
if(typeof(#{btnSumbit1})!='undefined' && #{btnSumbit1}!=null)#{btnSumbit1}.setDisabled(!isCheckd);
var valCs=isCheckd ? 'valaccept' : 'valexclamation';
if (msg=='') msg=isCheckd ? '<span style=\'color:green;\'>验证通过，可以提交数据</span>' : '<span style=\'color:red;\'>输入有误，请检查标红的输入项。</span>';
this.getBottomToolbar().setStatus({text :msg, iconCls: valCs});showMsg('温馨提示',msg,valCs);
"
;
|
顺便解释一下：
- 支持在页面上写自定义验证函数“ValCustomValidator”。存在与否都不会引发异常。
- 支持页面上防止保存提交按钮，存在与否也没关系。
- 你还可以根据自己的情况自定义。
因为这里是通用的，比如默认给每一个表单使用这个验证脚本。那么如何实现自定义验证呢？先欣赏两幅美图：
然后右下角就来提示了：
这里再贴上具体的JS：

看到上面那一串ID没，这就是不使用IDMode的后果。因为刚开始接触，未发现有这么个好东东。
