I have received an error message when I run my program. I feel this is a common type of error. Can you explain this error in simple terms.

Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1061: 'ASP.searchbygenre_aspx' does not contain a definition for 'ddlGenre_SelectedIndexChanged' and no extension method 'ddlGenre_SelectedIndexChanged' accepting a first argument of type 'ASP.searchbygenre_aspx' could be found (are you missing a using directive or an assembly reference?)

Source Error:


Line 6:      <p>
Line 7:          Choose a Genre:
Line 8:          <asp:DropDownList ID="ddlGenre" runat="server" AutoPostBack="True" OnSelectedIndexChanged="ddlGenre_SelectedIndexChanged">
Line 9:          </asp:DropDownList>
Line 10:     </p>

推荐答案

根据错误消息，在您的首页上( c:\ Users \ Jithma Senarathne \ Desktop \ fiverr \ asp.net \ Project \ Cinema网站\电影院网站\电影院网站\ SearchByGenre.aspx )，您可能会有一个下拉列表(名为 ddlGenre )，该列表绑定到 OnSelectedIndexChanged 事件 ddlGenre_SelectedIndexChanged，但是 SearchByGenre.aspx.cs 文件中后面的代码中没有该方法.您应该做的是:

According to the error message, in your front page (c:\Users\Jithma Senarathne\Desktop\fiverr\asp.net\Project\Cinema Website\Cinema Website\Cinema Website\SearchByGenre.aspx), you may have a dropdownlist (named ddlGenre) which is bound the OnSelectedIndexChanged event ddlGenre_SelectedIndexChanged, but there doesn't have the method in the code behind in the SearchByGenre.aspx.cs file. What you should do is:

1. 或者删除首页 SearchByGenre.aspx 第8行中的事件绑定代码: AutoPostBack ="True" OnSelectedIndexChanged ="ddlGenre_SelectedIndexChanged" ，

1. either remove the event binding code in front page SearchByGenre.aspx line 8: AutoPostBack="True" OnSelectedIndexChanged="ddlGenre_SelectedIndexChanged",

或在 SearchByGenre.aspx.cs 文件中后面的代码处添加事件方法.

or add the event method at code behind in the SearchByGenre.aspx.cs file.
