错误：

无法更新 EntitySet 'ClientFeedBack'，因为它具有 DefiningQuery 并且<InsertFunction>元素中不存在<ModificationFunctionMapping>支持当前操作的元素。

代码：

protected void DetailsView1_ItemInserting(object sender, DetailsViewInsertEventArgs e)
{
    ProTrakEntities1 objEntity = new ProTrakEntities1(); 
    TextBox txtTitle = DetailsView1.FindControl("txtTask") as TextBox;
    RadComboBox cmbStatus = DetailsView1.FindControl("cmbStatus") as RadComboBox;  

    RadComboBox cmbTaskType = DetailsView1.FindControl("cmbTasktype") as RadComboBox;  
    RadComboBox cmbTaskPriorty = DetailsView1.FindControl("cmbPriority") as RadComboBox;

    string Description = (DetailsView1.FindControl("RadEditor1") as RadEditor).Content;

    ClientFeedBack objResource = new ClientFeedBack();
    objResource.Title = txtTitle.Text;
    objResource.Description = Description;

    objResource.TaskPriorityID = Convert.ToInt32(cmbTaskPriorty.SelectedValue);
    objResource.TaskTypeID = Convert.ToInt32(cmbTaskType.SelectedValue);

    objEntity.AddToClientFeedBacks(objResource);
    objEntity.SaveChanges();

    DetailsView1.ChangeMode(DetailsViewMode.ReadOnly);
    ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "CloseAndRebind('navigateToInserted');", true);
}

我的表名是ClientFeedBack.

检查主键，检查您的表 ClientFeedBack 是否定义了主键。
