在Gridview的页脚中显示gridview的记录总数

Question

为了达到信息目的，我必须显示gridview中存在的记录总数。

我想表明，在GridView的页脚

总记录为“”的记载。

这里是我的gridview的ASPX代码

<asp:GridView ID="grdTeacherProfile" 
       runat="server" 
       Width="100%"

CS代码隐藏： -

public void BindGrid()

     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

Answer 1

由于第一个答案太冗长，所以写了一个全新的答案。 在GridView上设置ShowFooter="true"。接下来编辑第一TemplateField这样的：

<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> 

而这一切，你应该需要。至少在我测试的时候工作。 还应该有一些方法来跨越文本到几列，但没有时间来测试..

Answer 2

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

试试这个代码。
