Show Gridview Header and Footer when there is No Data / Empty in Asp.net

Jun 10, 2015
Introduction

Here I will explain how to display or show
gridview header and footer when the gridview is empty in asp.net using c#, vb.net with example or show gridview header and footer when there is no data or empty in asp.net using c#, vb.net with example. By using gridview properties ShowHeaderWhenEmpty, EmptyDataText we can show gridview header even when data is empty but to show footer we need to write custom code by adding new to gridview in asp.net.


By using gridview properties ShowHeaderWhenEmpty, EmptyDataText we can show gridview header even when data is empty but if we want to show footer also means we need to write custom code. Before implement this example first design one table productinfo in your database as shown below

Column Name
Data Type
Allow Nulls
productid
Int(IDENTITY=TRUE)
Yes
productname
varchar(50)
Yes
price
varchar(50)
Yes
Once table created in database enter some dummy data to test application now open your aspx page and write the code like as shown below


<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Show Gridview Header and Footer When Gridview Empty in Asp.net</title>
<style type="text/css">
.GridviewDiv {font-size: 100%; font-family: 'Lucida Grande', 'Lucida Sans Unicode', Verdana, Arial, Helevetica, sans-serif; color: #303933;}
.headerstyle
{
color:#FFFFFF;border-right-color:#abb079;border-bottom-color:#abb079;background-color: #df5015;padding:0.5em 0.5em 0.5em 0.5em;text-align:center;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div class="GridviewDiv">
<asp:GridView ID="gvDetails" runat="server" AutoGenerateColumns="false" ShowFooter="true" ShowHeaderWhenEmpty="true" EmptyDataText="No Records Found">
<HeaderStyle CssClass="headerstyle" />
<Columns>
<asp:TemplateField HeaderText="Product Id">
<ItemTemplate>
<asp:Label ID="lblId"  runat="server" Text='<%#Eval("productid") %>'/>
</ItemTemplate>
<FooterTemplate>
Footer1
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Product Name">
<ItemTemplate>
<asp:Label ID="lblName"  runat="server" Text='<%#Eval("productname") %>'/>
</ItemTemplate>
<FooterTemplate>
Footer2
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Price">
<ItemTemplate>
<asp:Label ID="lblPrice"  runat="server" Text='<%#Eval("price") %>'/>
</ItemTemplate>
<FooterTemplate>
Footer2
</FooterTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</div>
</form>
</body>
</html>

After completion of aspx page add following namespaces in codebehind

C# Code


using System;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;

After completion of adding namespaces you need to write the code like as shown below


protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGridview();
}
}
protected void BindGridview()
{
DataSet ds = new DataSet();
using (SqlConnection con = new SqlConnection("Data Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB"))
{
con.Open();
SqlCommand cmd = new SqlCommand("select * from productinfo where productid=0", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
con.Close();
if (ds.Tables[0].Rows.Count == 0)
{
ds.Tables[0].Rows.Add(ds.Tables[0].NewRow());
gvDetails.DataSource = ds;
gvDetails.DataBind();
int columncount = gvDetails.Rows[0].Cells.Count;
gvDetails.Rows[0].Cells.Clear();
gvDetails.Rows[0].Cells.Add(new TableCell());
gvDetails.Rows[0].Cells[0].ColumnSpan = columncount;
gvDetails.Rows[0].Cells[0].Text = "No Records Found";
}
else
{
gvDetails.DataSource = ds;
gvDetails.DataBind();
}
}
}

VB.NET Code


Imports System.Web.UI.WebControls
Imports System.Data
Imports System.Data.SqlClient
Partial Class VBCode
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
If Not IsPostBack Then
BindGridview()
End If
End Sub
Protected Sub BindGridview()
Dim ds As New DataSet()
Using con As New SqlConnection("Data Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB")
con.Open()
Dim cmd As New SqlCommand("select * from productinfo where productid=0", con)
Dim da As New SqlDataAdapter(cmd)
da.Fill(ds)
con.Close()
If ds.Tables(0).Rows.Count = 0 Then
ds.Tables(0).Rows.Add(ds.Tables(0).NewRow())
gvDetails.DataSource = ds
gvDetails.DataBind()
Dim columncount As Integer = gvDetails.Rows(0).Cells.Count
gvDetails.Rows(0).Cells.Clear()
gvDetails.Rows(0).Cells.Add(New TableCell())
gvDetails.Rows(0).Cells(0).ColumnSpan = columncount
gvDetails.Rows(0).Cells(0).Text = "No Records Found"
Else
gvDetails.DataSource = ds
gvDetails.DataBind()
End If
End Using
End Sub
End Class
