Question

我必须显示gridview中存在的总记录数，以供参考。

我想在Gridview页脚中显示为

总记录是＆＃34;＆＃34;记录。

这是我的gridview aspx代码

CS Codebehind： -

public void BindGrid()
    {
        string conString = ConfigurationManager.ConnectionStrings["DefaultCSRConnection"].ConnectionString;
        SqlCommand cmd = new SqlCommand("Select Id, first_name, last_name,emailid, dob, gender, designation, joining_date, leaving_date, active from tbl_teachers_profile Order by Id desc");
        using (SqlConnection con = new SqlConnection(conString))
        {
            using (SqlDataAdapter sda = new SqlDataAdapter())
            {
                cmd.Connection = con;
                sda.SelectCommand = cmd;
                using (DataTable dt = new DataTable())
                {
                    sda.Fill(dt);
                    grdTeacherProfile.DataSource = dt;
                    grdTeacherProfile.DataBind();
                    DisablePageDirections();
                    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ShowFooter="true"上设置GridView。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>

这就是你应该需要的。至少在我测试时有效。还应该有一些方法可以将文本扩展到几列，但没有时间来测试它......

Answer 2

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

试试这段代码。
