如何在GridView中刪除特定行的行或禁用刪除按鈕？

Question

我在如何為rowindex = 0禁用GridView Delete Button時遇到問題。

其次，我想Delete一個Row上的Delete Button點擊。

我的GridView在這里僅用於獲取數據。 我正在使用ak創建新行，並將其用作GridView DataSource 。

  <asp:gridview ID="Gridview1" runat="server" ShowFooter="true" AutoGenerateColumns="false" AutoGenerateDeleteButton="true" OnRowDeleting="Gridview1_RowDeleting">
            <Columns>
            <asp:BoundField DataField="RowNumber" HeaderText="Row Number" />
            <asp:TemplateField HeaderText="WorkDone">
                <ItemTemplate>
                    <asp:TextBox ID="txtWorkDone" runat="server"></asp:TextBox>
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField HeaderText="Total Time spent">
                <ItemTemplate>
                    <asp:DropDownList runat="server" ID="ddlHours">
                        <asp:ListItem Selected="True">1</asp:ListItem>
                        <asp:ListItem>2</asp:ListItem>
                        <asp:ListItem>3</asp:ListItem>
                        <asp:ListItem>4</asp:ListItem>
                        <asp:ListItem>5</asp:ListItem>
                        <asp:ListItem>6</asp:ListItem>
                        <asp:ListItem>7</asp:ListItem>
                        <asp:ListItem>8</asp:ListItem>
                        <asp:ListItem>9</asp:ListItem>
                    </asp:DropDownList>

                </ItemTemplate>
                <FooterStyle HorizontalAlign="Right" />
                <FooterTemplate>
                 <asp:Button ID="btnAddNewRow" runat="server" Text="Add New Row" 
                        onclick="btnAddNewRow_Click" CausesValidation="false"/>
                </FooterTemplate>
            </asp:TemplateField>

            </Columns>
        </asp:gridview>

但我不知道在事件RowDeleting內部要實現什么

           //Here i am not getting
        }
