下拉值获得一些不必要的数据 [英] Dropdown value get some unnecessary data
问题描述
我有一个依赖的下拉菜单。
类别和名称
指定取决于类别。在类别指定数据的chagne得到。
但是当我直接点击时间指定时..默认初始值设置(指定ID)。每个选项都包含一个单词。
opetion1:d,
option2:e,
option3:s,
选项4:我
选项5:g,
等等..
< option> d< option>
< option> e< option>
< option> s< option>
< option> i< option>
< pre>< option> ..指定..< option>
我的尝试:
< div class =input-field col s6>
@ Html.DropDownList(DesignationId,new SelectList(DesignationId,DesignationName),Select Job Post,new {@class =validate select-active})
< label for =Departmentclass => Department< / label>
< / div>
Quote:
新的SelectList(DesignationId,DesignationName)
查看文档 [ ^ ],第一个参数SelectList
构造函数是一个IEnumerable
序列,包含要显示的值。
您传入的是String
,这是一个可枚举的字符序列。因此,您的列表将包含字符串中每个字符的一个条目。
相反,您需要传入一个可枚举的指定序列作为第一个参数。
i have one dependent dropdown.
category and designation
designation is dependent on category. on chagne of category designation data get.
but when i direct click on designation that time .. default initial value set (designationid). every option contain one word.
opetion1 : d ,
option2 : e ,
option3: s ,
option4 : i
option5 : g ,
and so on..
<option>d<option>
<option>e<option>
<option>s<option>
<option>i<option>
<pre><option>..designation ..<option>
What I have tried:
<div class="input-field col s6"> @Html.DropDownList("DesignationId", new SelectList("DesignationId", "DesignationName"), "Select Job Post", new { @class = "validate select-active" }) <label for="Department" class="">Department</label> </div>
Quote:
new SelectList("DesignationId", "DesignationName")
Looking at the documentation[^], the first argument to theSelectList
constructor is anIEnumerable
sequence containing the values to display.
You are passing in aString
, which is an enumerable sequence of characters. Therefore, your list will contain one entry for each character in the string.
Instead, you need to pass in an enumerable sequence of designations as the first parameter.
