asp.net bind a list to a gridview

List<MasterBook> listOfBooks = new List<MasterBook>();

after i put the masterbook objects which by the way have 3 fields( name,id and active ) into the list

 GridView1.DataSource = listOfBooks;
 GridView1.DataBind();

in the web form 

   <Columns>

            <asp:TemplateField HeaderText="Book Name">
                <ItemTemplate>
                    <asp:Label ID="BookNameText" runat="server" 
                            Text="<%#Container.DataItem%>">

                    </asp:Label>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>

    </asp:GridView>

Use this sintax:

<asp:Label ID="BookNameText" runat="server" 
                        Text="<%# ((MasterBook)Container.DataItem).Name %>">

Change: 

  <%#Container.DataItem%>

To:

  <%#Eval("name")%>

The quick, dirty hack workaround is to overload the ToString() method of your MasterBookclass in order to return that name. Commit seppuku afterwards if you do it.

The elegant and graceful way is to make an object datasource. That way you can bind the grid view's columns to the objects' properties. In the case of a DataList or other templated data controls, you can bind your objects' properties to the data control's child controls in their templates.

The middle path is in hutchonoid's answer: evaluate a property of the object, not the object itself.

Cast it to MasterBook:

Text="<%# ((MasterBook) Container.DataItem).Name %>">
