实现不带内联编辑GridView编辑按钮

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
    <Columns>
        <asp:BoundField DataField="Name" HeaderText="Name" />
        <asp:BoundField DataField="Age" HeaderText="Age" />
        <asp:TemplateField HeaderText="Edit">
            <ItemTemplate>
                <asp:Button ID="btnEdit" runat="server" Text="Edit" OnClick="btnEdit_Click" />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

protected void btnEdit_Click(object sender, EventArgs e)
{
    Button btnEdit = (Button)sender;
    GridViewRow row = (GridViewRow)btnEdit.NamingContainer;
    int rowIndex = row.RowIndex;

    // 获取当前编辑行的数据
    string name = GridView1.Rows[rowIndex].Cells[0].Text;
    int age = Convert.ToInt32(GridView1.Rows[rowIndex].Cells[1].Text);

    // 执行编辑操作，例如更新数据库中的数据

    // 重新绑定数据源并刷新GridView
    BindGridView();
}

private void BindGridView()
{
    // 绑定数据源到GridView
    // 例如：GridView1.DataSource = 数据源;
    //      GridView1.DataBind();
}
