如何保持所有下拉列表的宽度和高度相同？ [英] How to keep width and height of all dropdownlist as same?

问题描述

我在visual studio中制作了一个Web应用程序。

我想保持所有下拉列表的宽度相同。我有3个下拉列表，所有宽度都不同。我必须使用百分比而不是像素来保持它们相同

解决方案

使用 css 。

。 ddl  {
  width  ：  20％;  
 高度 ：  10％;  
  / *  宽度 - 高度无论你想要什么* /  
} 

 <   asp：dropdownlist     id   =  ddl1    runat   =  server    cssclass   =  ddl    xmlns：asp   = ＃unknown >  
 <   / asp：dropdownlist   >  
 <   asp：dropdownlist     id   =  ddl2     runat   = < span class =code-keyword> server    cssclass   =  ddl   < span class =code-attribute> xmlns：asp   = ＃unknown < span class =code-keyword>>  
 <   / asp：dropdownlist  >  
 <   asp ：dropdownlist     id   =  ddl3    runat   =  server    cssclass   =  ddl    xmlns：asp   =  #unknown >  
 <   / asp：dropdownlist  >

解决方案

By using css.

.ddl{
    width: 20%;
    height:10%; 
/*width - height whatever you want*/
}

<asp:dropdownlist id="ddl1" runat="server" cssclass="ddl" xmlns:asp="#unknown">
</asp:dropdownlist>
<asp:dropdownlist id="ddl2" runat="server" cssclass="ddl" xmlns:asp="#unknown">
</asp:dropdownlist>
<asp:dropdownlist id="ddl3" runat="server" cssclass="ddl" xmlns:asp="#unknown">
</asp:dropdownlist>
