Hola, todos creé un proyecto que tiene una vista de formulario vinculada a una vista de cuadrícula. Todos los demás comandos parecen funcionar bien, excepto cuando intento actualizar la vista de formulario, aparece el error en el título. Aquí está mi código.

    <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:

             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="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>

No estoy seguro de a dónde ir desde aquí
