Question

我正在尝试在我的asp.net webforms应用程序中使用Ninject 3。它工作正常，但包含ObjectDataSource的某些网页，Select的{{1}}方法会抛出ObjectDataSource。我的代码如下：

NullReferenceException：

Web.Admin.Grades.aspx

<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" EnablePaging="true" TypeName="Web.Admin.Grades" SelectMethod="GetData" SelectCountMethod="GetDataCount" StartRowIndexParameterName="StartRowIndex" MaximumRowsParameterName="MaximumRows"> <SelectParameters> <asp:ControlParameter ControlID="SearchTxtBox" Type="String" Name="SearchKeyWord" PropertyName="Text" /> </SelectParameters> </asp:ObjectDataSource>：

Web.Admin.Grades.cs

Answer 1

很抱歉误会我解决了这个问题如下

 <asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
                EnablePaging="true" TypeName="Domain.Abstract.IGradesRepository"
                SelectMethod="GetGrades" SelectCountMethod="GetGradesCount"   OnObjectCreating="ObjectDataSource1_ObjectCreating"
                StartRowIndexParameterName="StartRowIndex" MaximumRowsParameterName="MaximumRows">
                <SelectParameters>
                    <asp:ControlParameter ControlID="SearchTxtBox" Type="String" Name="SearchKeyWord"  PropertyName="Text" />
                </SelectParameters>
            </asp:ObjectDataSource>

和Web.Admin.Grades.cs：

[Inject]
    public IGradesRepository _Grades { get; set; }
protected void ObjectDataSource1_ObjectCreating(object sender, ObjectDataSourceEventArgs e)
    {
        e.ObjectInstance = _Grades;
    }

在asp.net webforms中使用Ninject和objectdatasource？
