You are going to need to define the button control inside of the <Columns> section of your GridView markup, like this:

<asp:gridview id="CustomersGridView" runat="server">
    <columns>
        <asp:boundfield datafield="DateColumn" headertext="Date"/>
        <asp:TemplateField>
            <HeaderTemplate>
                Positive
            </HeaderTemplate>
            <ItemTemplate>
                <asp:Label id="LabelPositive" runat="server" Text='<%# Eval("PositiveColumn")%>' />
                <br />
                <asp:Button id="ButtonPositive" runat="server" Text="Show" />
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField>
            <HeaderTemplate>
                Negative
            </HeaderTemplate>
            <ItemTemplate>
                <asp:Label id="LabelNegative" runat="server" Text='<%# Eval("NegativeColumn")%>' />
                <br />
                <asp:Button id="ButtonNegative" runat="server" Text="Show" />
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField>
            <HeaderTemplate>
                Neutral
            </HeaderTemplate>
            <ItemTemplate>
                <asp:Label id="LabelNeutral" runat="server" Text='<%# Eval("NeutralColumn")%>' />
                <br />
                <asp:Button id="ButtonNeutral" runat="server" Text="Show" />
            </ItemTemplate>
        </asp:TemplateField>
        <asp:boundfield datafield="NoCommentsColumn" headertext="No Comments"/>
        <asp:boundfield datafield="TotalColumn" headertext="Total"/>
    </columns>
</asp:gridview>

Note: The datafield and Eval() calls are bound to made up names like NeutralColumn and NoCommentsColumn , substitute those names with your real database field names.

You need to add while data binding the grid. Look for an event call and handle your code there.
