Problem to Link button

Hi,
There is Link button below, to the GV

        <asp:GridView ID="gvResult" runat="server" 
            CellPadding="4" ForeColor="#333333" Font-Size="12px" 
            AutoGenerateColumns="False" PageSize="20" 
            DataKeyNames="id"
            style="margin-top: 1px" AllowPaging="True" 
            onpageindexchanging="gvResult_PageIndexChanging" 
            OnRowDataBound="gvResult_RowDataBound" onrowcommand="gvResult_RowCommand">
            <PagerSettings Mode="NumericFirstLast" />
            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
            <Columns>
                <asp:TemplateField ShowHeader="False">
                    <ItemTemplate>
                        <asp:LinkButton ID="lbEdit" runat="server" CausesValidation="False" 
                            CommandName="RowEdit" Text="更改資料" CommandArgument='<%# Eval("Id") %>'></asp:LinkButton>
                            
                        <asp:LinkButton ID="lbEdit2" runat="server" CausesValidation="False" 
                            CommandName="RowEdit2" Text="更改資料" CommandArgument='<%# Eval("Id") %>'></asp:LinkButton>
                    </ItemTemplate>
					...

Open in new window

when running the page, the Link button is not shown. But I cannot find out any codes, which are hiding such Link button. Why?

Is the grid showing and did you see any error message?
You may want to provide a screenshot.

is your datagrid bind to a datasource and got records returned to the screen?

Yes, GV is binding to a datasource.
Why can't I see the codes that are disabling the button below

                <asp:TemplateField ShowHeader="False">
                    <ItemTemplate>
                        <asp:LinkButton ID="lbEdit" runat="server" CausesValidation="False"
                            CommandName="RowEdit" Text="更改資料" CommandArgument='<%# Eval("Id") %>'></asp:LinkButton>
                           
                        <asp:LinkButton ID="lbEdit2" runat="server" CausesValidation="False"
                            CommandName="RowEdit2" Text="更改資料" CommandArgument='<%# Eval("Id") %>'></asp:LinkButton>
                    </ItemTemplate>
                    <ItemStyle HorizontalAlign="Center" Width="30px" />                   
                </asp:TemplateField>
                                ...

I don't have a VS with me right now, but you can do quick checks:

-ensure your linkbutton control is visible in the page (not using scripts to set the visible property to false)
-since it's within your GV control, ensure your GV column is not being hidden via scripts (not to set the column's visible property to false)
-there is data that binded to GV, NO data = Nothing will be shown

Sorry, GV is being shown. But I do not know why Linkbutton is not shown there.
