如何在SqlDataSource中参数化Update查询

Question

I am maintaining an old website, the code was pretty messy.

I want to use SqlDataSource to do the Updating, selecting, inserting functions. I really do not want to write the back-end code by myself. (I actually have already written all code, but the old code is too messy to test and does not have comments so it makes me very hard to detect where bugs are, so I have discarded the back-end code and am using SqlDataSource)

Instead, I'd like to use the UpdateCommand in SqlDataSource do to the update. Here is my Updating query:

UPDATE MedicareLocalAccounts SET Account=@Account and PWD=@PWD WHERE DivisionID=@DivisionID

The data source comes from 3 different tables.

 <asp:GridView ID="gv_MediCareLocals" runat="server" AllowPaging="True" AllowSorting="True"
            AutoGenerateColumns="False" DataKeyNames="LUDivisionsUID" ClientIDMode="Static" AutoGenerateEditButton="True"
            EnablePersistedSelection="True" DataSourceID="SqlDataSource1">
            <Columns>
                <asp:HyperLinkField DataTextField="LUDivisionsUID" HeaderText="Division ID" ShowHeader="true"
                    SortExpression="LUDivisionsUID" />
                <asp:BoundField DataField="Division" HeaderText="Medicare Local" ReadOnly="true" SortExpression="Division"/>
                <asp:BoundField DataField="States" HeaderText="State" ReadOnly="true" SortExpression="States" />

                <asp:TemplateField HeaderText="Account">
                    <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text='<%# Eval("Account") %>' />
                    </ItemTemplate>
                    <EditItemTemplate>
                        <input type="text" clientidmode="Static" runat="server" id="tbAccount" value='<%# Eval("Account") %>' />
                    </EditItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Password">
                    <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text='<%# Eval("PWD") %>' />
                    </ItemTemplate>
                    <EditItemTemplate>
                        <input type="text" clientidmode="Static" runat="server" id="tbPassword" value='<%# Eval("PWD") %>' />
                    </EditItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

So as you can see, I need to have the DivisionID parameterized as well, but the DivisionID field does not have an ID (not like the Account and Password). So How can I write the where clause in order to find the DivisionID in the current row?

Update: I have changed the DivisionID column to

  <asp:TemplateField HeaderText="DivisionID" SortExpression="LUDivisionsUID" >
                        <ItemTemplate>
                            <asp:Label runat="server" ID="lblDivisionID" Text='<%# Eval("LUDivisionsUID") %>'>' ></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>

But I got an error after I clicked the Update button.

Could not find control 'tbAccount' in ControlParameter 'Account'.

As you can see from the code, I have already applied the property ClientIDMode="Static" on both GridView and columns. I use Chrome to see the generated ids for the Account column and found the id=tbAccount, but the name="ctl00$PageTitlePlaceHolder$gv_MediCareLocals$ctl02$tbAccount"

I don't think the Sql UpdateParameter is going to use the name property anyway.

If u create a stored procedure then it will be easy.For that purpose visit this Link

Hope it works.
