In general for ASP.NET GridView control, it is bit difficult to handle

  • Fixed height when the number of rows are less in a page or when there is no data to display.
  • showing custom paging summary like showing 1-10 of 100 records

In this article, we tried to address both the issues using below code.


<%@ Page Language="C#" AutoEventWireup="true" CodeFile="FixedHeightGridViewEvenForLessRows.aspx.cs" Inherits="FixedHeightGridViewEvenForLessRows" %>
<html xmlns="">
<head runat="server">
    <title>GridView Fixed Height and Custom Paging</title>
    <form id="form1" runat="server">
            <asp:GridView ID="gvStudent" runat="server" Width="600px" AutoGenerateColumns="false"
                AllowPaging="true" OnPageIndexChanging="gridOfficalDocs_PageIndexChanging"
                OnDataBound="gridOfficalDocs_DataBound" ShowHeaderWhenEmpty="true" EmptyDataText="No records Found to Display!">
                <HeaderStyle Height="35px" BackColor="YellowGreen" />
                <FooterStyle Height="50px" />
                <RowStyle Height="20px" BackColor="#89EDB9" />
                <AlternatingRowStyle Height="20px" BackColor="#EA8F64" />
                    <asp:BoundField HeaderText="Roll No" DataField="rollno" />
                    <asp:BoundField HeaderText="Full Name" DataField="fullname" />
                    <asp:BoundField HeaderText="Gender" DataField="gender" />
                <PagerSettings Mode="Numeric" />
                <PagerStyle VerticalAlign="Bottom" />
                <EmptyDataRowStyle HorizontalAlign="Center" VerticalAlign="Top" />


using System;

public partial class FixedHeightGridViewEvenForLessRows : System.Web.UI.Page
    public int totalRowCount = 0;

        if (!IsPostBack)

    protected DataTable GetData()
        //create sample data here
        DataTable dt = new DataTable();

        for (int i = 1; i <= 12; i++)
            DataRow dr = dt.NewRow();
            dr["rollno"] = i.ToString();
            if (i % 2 == 0) //odd row
                dr["fullname"] = "Ramu";
                dr["gender"] = "Male";

    protected override void OnPreRender(EventArgs e)

    public void SetFixedHeightForGridIfRowsAreLess(GridView gv)
        double headerFooterHeight = gv.HeaderStyle.Height.Value + 35; //we set header height style=35px and there no footer  height so assume footer also same
        double rowHeight = gv.RowStyle.Height.Value;
        int gridRowCount = gv.Rows.Count;
        if (gridRowCount <= gv.PageSize)
            double height = (gridRowCount * rowHeight) + ((gv.PageSize - gridRowCount) * rowHeight) + headerFooterHeight;
            //adjust footer height based on white space removal between footer and last row
            height += 40;
            gv.Height = new Unit(height);

    protected void gridOfficalDocs_PageIndexChanging(object sender, GridViewPageEventArgs e)
        gvStudent.PageIndex = e.NewPageIndex;

    protected void gridOfficalDocs_DataBound(object sender, EventArgs e)
        createPagingSummaryOnPagerTemplate(sender, totalRowCount, pageSize);

    public void createPagingSummaryOnPagerTemplate(object sender, int totalCount, int pageSize)
        GridView gv = sender as GridView;
        if (gv != null)
            //Get Bottom Pager Row from a gridview
            GridViewRow row = gv.BottomPagerRow;

            if (row != null)
                //create new cell to add to page strip
                TableCell pagingSummaryCell = new TableCell();
                pagingSummaryCell.Text = DisplayCusotmPagingSummary(totalCount, gv.PageIndex, pageSize);
                pagingSummaryCell.HorizontalAlign = HorizontalAlign.Right;
                pagingSummaryCell.VerticalAlign = VerticalAlign.Middle;
                pagingSummaryCell.Width = Unit.Percentage(100);
                pagingSummaryCell.Height = Unit.Pixel(35);
                //Getting table which shows PagingStrip
                Table tbl = (Table)row.Cells[0].Controls[0];

                //BottomPagerRow will be visible false if pager doesn't have numbers and page number 1 will be displayed
                if (totalCount <= pageSize)
                    gv.BottomPagerRow.Visible = true;
                    tbl.Width = Unit.Percentage(100);
                //Find table and add paging summary text
                //assign header row color to footer row
                tbl.BackColor = System.Drawing.ColorTranslator.FromHtml("#1AD9F2");
                tbl.Width = Unit.Percentage(100);

    public static string DisplayCusotmPagingSummary(int numberOfRecords, int currentPage, int pageSize)
        StringBuilder strDisplaySummary = new StringBuilder();
        int numberOfPages;
        if (numberOfRecords > pageSize)
            // Calculating the total number of pages
            numberOfPages = (int)Math.Ceiling((double)numberOfRecords / (double)pageSize);
            numberOfPages = 1;
        strDisplaySummary.Append("Showing ");
        int floor = (currentPage * pageSize) + 1;
        int ceil = ((currentPage * pageSize) + pageSize);

        if (ceil > numberOfRecords)

        strDisplaySummary.Append(" of ");
        strDisplaySummary.Append(" results ");
        return strDisplaySummary.ToString();


GridView Page1

GridView Page2

From the output, we can observe

  •  GridView Page2 image has only two rows but the grid height is same as GridView Page1 image.
  •  Custom paging summary (Showing 1-10 of 12 results ) on right side of footer.

Showing fixed GridView height when there is no data to display:

From the code behind file, if we comment one line(//dt.Rows.Add(dr);) then Data Table will not return any data and output looks like

Hope this solves your issue!
