c# - GridView CS1061 错误

Question

这是 GridView 代码:

<asp:GridView ID="datagrid" runat="server" CssClass="mydatagrid" PagerStyle-CssClass="pager" HeaderStyle-CssClass="header" RowStyle-CssClass="rows" AllowPaging="True" OnPageIndexChanging="datagrid_PageIndexChanging">
</asp:GridView>

这是 C# 代码:

string str = "Data Source=(LocalDB)\\MSSQLLocalDB;";
str += "AttachDbFilename=|DataDirectory|DinoData.mdf;";
str += "Integrated Security= True";

SqlConnection c;
c = new SqlConnection(str);

DataTable dt = new DataTable();
String req = "SELECT * FROM [User]";
SqlDataAdapter da = new SqlDataAdapter(req, c);
da.Fill(dt);
datagrid.DataSource = dt;
datagrid.DataBind();

错误:

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.manger_search_aspx' does not contain a definition for 'datagrid_PageIndexChanging' and no extension method 'datagrid_PageIndexChanging' accepting a first argument of type 'ASP.manger_search_aspx' could be found (are you missing a using directive or an assembly reference?)

Answer 1

您将 asp 中的属性 OnPageIndexChanging 设置为 datagrid_PageIndexChanging 表示将有一个处理程序来处理 OnPageIndexChanging 事件。

如果你没有在任何地方声明这个处理程序，你会得到这个编译器错误。因此，如果您不需要/不需要该处理程序，请从您的 asp:GridView 标记中删除该属性。
