问题描述

大家好，我创建绑定了一个GridView一个FormView的项目。所有其他的命令似乎除了当我尝试更新表单视图我得到错误的标题很好地工作。这里是我的code。

Hi all I created a project that has a Formview bound to a Gridview. All the other commands seem to work fine except when I try to update the form view I get the error in the title. Here is my code.

    <EditItemTemplate>
         num:

         <asp:TextBox ID="TextBox1" runat="server" 
             Text='<%# Bind("[num]") %>' />
         <br />   
         Job Title:
         <asp:TextBox ID="Job_TitleTextBox" runat="server" 
             Text='<%# Bind("[Job Title]") %>' />
         <br />
         Status:
         <asp:TextBox ID="StatusTextBox" runat="server" Text='<%# Bind("Status") %>' />
         <br />
         Department:
         <asp:TextBox ID="DepartmentTextBox" runat="server" 
             Text='<%# Bind("Department") %>' />
         <br />
         Date Position Available:
         <asp:TextBox ID="Date_Position_AvailableTextBox" runat="server" 
             Text='<%# Bind("[Date Position Available]") %>' />
         <br />
         Position Type:
         <asp:TextBox ID="Position_TypeTextBox" runat="server" 
             Text='<%# Bind("[Position Type]") %>' />
         <br />
         Job Duties:
         <asp:TextBox ID="Job_DutiesTextBox" runat="server" 
             Text='<%# Bind("[Job Duties]") %>' />

         <br />
         Qualifications:
         <asp:TextBox ID="QualificationsTextBox" runat="server" 
             Text='<%# Bind("Qualifications") %>' />
         <br />
         Physical Demands:
         <asp:TextBox ID="Physical_DemandsTextBox" runat="server" 
             Text='<%# Bind("[Physical Demands]") %>' />
         <br />
         Closing Date:
         <asp:TextBox ID="Closing_DateTextBox" runat="server" 
             Text='<%# Bind("[Closing Date]") %>' />
         <br />
         Hours Per Pay Period:
         <asp:TextBox ID="Hours_Per_Pay_PeriodTextBox" runat="server" 
             Text='<%# Bind("[Hours Per Pay Period]") %>' />
         <br />
         <asp:LinkButton ID="UpdateButton" runat="server" CausesValidation="True" 
             CommandName="Update" Text="Update" />
         &nbsp;<asp:LinkButton ID="UpdateCancelButton" runat="server" 
             CausesValidation="False" CommandName="Cancel" Text="Cancel" />
     </EditItemTemplate>

    UpdateCommand="UPDATE [career_posting] SET [Job Title] = @Job_Title, [Status] = @Status, [Department] = @Department, [Date Position Available] = @Date_Position_Available, [Position Type] = @Position_Type, [Job Duties] = @Job_Duties, [Qualifications] = @Qualifications, [Physical Demands] = @Physical_Demands, [Closing Date] = @Closing_Date, [Hours Per Pay Period] = @Hours_Per_Pay_Period WHERE [num] = @num">

     <UpdateParameters>
         <asp:Parameter Name="Job_Title" Type="String" />
         <asp:Parameter Name="Status" Type="String" />
         <asp:Parameter Name="Department" Type="String" />
         <asp:Parameter Name="Date_Position_Available" Type="String" />
         <asp:Parameter Name="Position_Type" Type="String" />
         <asp:Parameter Name="Job_Duties" Type="String" />
         <asp:Parameter Name="Qualifications" Type="String" />
         <asp:Parameter Name="Physical_Demands" Type="String" />
         <asp:Parameter Name="Closing_Date" Type="String" />
         <asp:Parameter Name="Hours_Per_Pay_Period" Type="String" />
         <asp:Parameter Name="num" Type="Int32" />
     </UpdateParameters>
 </asp:SqlDataSource>

我不知道从这里到

推荐答案

下面是从的这个参考：

检查SqlDataSource的对象为你拉或重命名的任何字段
  在他们的空间。一个'_'下划线将正常工作，但做了
  像这样的查询选择[somename]为[部分名] FROM [名] WHERE
  [ID] = @ ID将导致上述错误

Check the SqlDataSource object for any fields you’ve pulled or renamed with spaces in them. An ‘_’ Underscore will work fine, but doing a query like this "Select [somename] as [Some Name] FROM [names] WHERE [id]=@id" will result in the above error

试着用下划线替代所有的空间（例如JOB_TITLE）

Try replacing all the spaces with underscores (e.g. Job_Title)
