文本框已更改为下拉列表，然后此错误消息 [英] Text box was changed to a dropdownlist and then this error messase

问题描述

分析器错误消息：基类包含字段'txt_Brn_Name'，但其类型（System.Web.UI.WebControls.TextBox）与控件类型（System.Web.UI.WebControls.DropDownList）不兼容。

 <   asp：DropDownList     ID   =  txt_Brn_Name    runat   =  server    AutoPostBack   =  True  
   
  高度  =  16px    onselectedindexchanged   =  txt_Brn_Name_SelectedIndexChanged  
   
  宽度  =  201px >  
 <   asp： ListItem  >  

下面有一条蓝线下面的陈述

 <   asp：DropDownList     ID   =  txt_Brn_Name    runat   =  server    AutoPostBack   = 真   

如何更正此错误？

谢谢



我尝试了什么：



我在网上搜索了解析，我无法从我发现的内容中找出任何意义

解决方案

您在HTML中更改了它，但在页面类C＃代码中没有更改：使用VS查找所有引用，您应该看到CS定义。

HI，



试用一个测试用例：

1.添加一个原始控件下拉列表。

2.比较两个控件。



尝试识别错误并删除

Parser Error Message: The base class includes the field 'txt_Brn_Name', but its type (System.Web.UI.WebControls.TextBox) is not compatible with the type of control (System.Web.UI.WebControls.DropDownList).

<asp:DropDownList ID="txt_Brn_Name" runat="server" AutoPostBack="True"

Height="16px" onselectedindexchanged="txt_Brn_Name_SelectedIndexChanged"

Width="201px">
<asp:ListItem>

There is a blue line under the statement below

<asp:DropDownList ID="txt_Brn_Name" runat="server" AutoPostBack="True" 

How do I correct this error?

New Bie

Thanks

What I have tried:

I searched for the parse on the net and i cant make any meaning out of what I found

解决方案

You changed it in the HTML, but not in your Page class C# code: Use VS to "Find All References" and you should see the CS definition.

HI,

Try a test case :
1. Add an original control of dropdown.
2. Compare both controls.

Try to identify the error and remove that.
