这是我的标记:
<div class="postit">
<ul>
<li>
<asp:Label ID="lblPostBaslik" runat="server" Text="Baslik :" CssClass="postit-label"></asp:Label>
<asp:TextBox ID="txtBaslik" runat="server" CssClass="postit-txtbox" ></asp:TextBox>
</li>
<li>
<asp:Label ID="lblPostEtiket" runat="server" Text="Etiket :" CssClass="postit-label"></asp:Label>
<asp:TextBox ID="txtEtiket" runat="server" CssClass="postit-txtbox" ></asp:TextBox>
<li class="aciklama">
<asp:Label ID="lblAciklama" runat="server" Text="Açiklama :" CssClass="postit-label"></asp:Label>
<asp:TextBox ID="txtAciklama" runat="server" CssClass="postit-txtbox-aciklama" TextMode="MultiLine" ></asp:TextBox>
</li>
<div class="postitbuttons" id="postitbuttons">
<asp:Button ID="btnKaydet" runat="server" Text="Kaydet" CssClass="submit button large" onclick="btnKaydet_Click" />
<asp:Button ID="btnVazgec" runat="server" Text="Vazgeç" CssClass="submit button large"/>

<asp:LinkButton ID="btnKapat" runat="server" CssClass="submit button large" CommandName="Cancel">Vazgeç</asp:LinkButton>--%>
</div>
</li>
</ul>
</div>
<asp:ObjectDataSource ID="ods_postit" runat="server" DataObjectTypeName="Post" TypeName="yonet" InsertMethod="PostEkle" >
<InsertParameters>
<asp:ControlParameter ControlID="txtBaslik" PropertyName="Text" Name="Post_Baslik" Type="String" />
<asp:ControlParameter ControlID="txtEtiket" PropertyName="Text" Name="Post_Etiket" Type="String" />
<asp:ControlParameter ControlID="txtEtiket" PropertyName="Text" Name="Post_Icerik" Type="String" />
</InsertParameters>
</asp:ObjectDataSource>
当我点击btnKaydet时,我收到以下错误:
“ObjectDataSource'odss_postit'没有要插入的值。请检查'values'字典是否包含值。”
有什么问题?它可以是这样的:
<asp:ObjectDataSource ID="ods_postit" runat="server" DataObjectTypeName="Post" TypeName="yonet" InsertMethod="PostEkle" >
我尝试断点,但它不会触发databaseworks.cs和yonet.cs。
我不能使用这个OOP代码吗?我不想使用像(formview等)这样的表格。
这是代码隐藏和其他类:
protected void btnKaydet_Click(object sender, EventArgs e)
{
ods_postit.Insert();
}
Post.cs
public class Post
{
//Post Private Özellikleri

private Guid _post_user_id;
private string _post_baslik;
private string _post_etiket;
private string _post_icerik;
//Post Public Özellikleri
public int Post_ID
{
get { return _post_id; }
set { _post_id = value; }
}
public Guid Post_User_ID
{
get { return _post_user_id; }
set { _post_user_id = value; }

set { _post_baslik = value; }
}
public string Post_Etiket
{

set { _post_etiket = value; }
}
public string Post_Icerik
{
get { return _post_icerik; }
set { _post_icerik = value; }
}
}
databaseworks.cs
public static void PostEkle(Post post)
{
using (SqlConnection baglanti = new SqlConnection(dbconnect()))
{
SqlCommand komut = new SqlCommand("sp_post_ekle", baglanti);
komut.CommandType = CommandType.StoredProcedure;
komut.Parameters.AddWithValue("post_id", post.Post_ID);
komut.Parameters.AddWithValue("post_user_id",Membership.GetUser().ProviderUserKey);
komut.Parameters.AddWithValue("post_baslik", post.Post_Baslik);
komut.Parameters.AddWithValue("post_etiket","#" + post.Post_Etiket);
komut.Parameters.AddWithValue("post_icerik", post.Post_Icerik);
baglanti.Open();
komut.ExecuteNonQuery();
baglanti.Close();
}
}
yonet.cs
public static void PostEkle(Post post)
{
databaseworks.PostEkle(post);
}

FormView或DetailsView处理UI控件和数据源之间的集成,以及您没有指定的Bind语句的所有绑定(我认为即使您使用ControlParameter也很重要;要么,或者控件参数可以工作但是你需要FormView控件。
此外,ODS在你的场景中没有获得任何东西;您可以完全转储ObjectDataSource,将对象中的数据推送到业务层并将数据写入命令。
