                    grdTeacherProfile.BottomPagerRow.Visible = true;
                }
            }
        }
    }

请帮忙

Answer 1

写一个全新的答案，因为第一个答案太冗长了。 在您的GridView 上设置ShowFooter="true"。接下来编辑第一个TemplateField，如下所示：

<asp:TemplateField HeaderText="Select" ItemStyle-Width="5">
    <ItemTemplate>
        <asp:CheckBox ID="chkDelete" runat="server" onClick="Check_Click(this)" />
    </ItemTemplate>
    <FooterTemplate>
        Number of records: <%# grdTeacherProfile.Rows.Count %>
    </FooterTemplate>
</asp:TemplateField>

这就是您所需要的。至少在我测试时有效。 还应该有一些方法可以将文本跨越到几列，但没有时间测试..

Answer 2

int RowCount = grdTeacherProfile.Rows.Count;
lblDisplayCount.Text = RowCount.ToString();

试试这个代码。
