Insert data in ASP GridView Without Having Making Use of Database

Multiple Rows and columns will be added to GridView with the help of DataTable in ViewState or Session thus the GridView is populated without using database.

HTML Markup

The following HTML Markup consists of an ASP.Net GridView along with some TextBoxes and a Button in order to insert data in GridView control.

<asp:GridView ID="GridView1" runat="server" CssClass="Grid" AutoGenerateColumns="false"
EmptyDataText="No records has been added.">
<Columns>
    <asp:BoundField DataField="Name" HeaderText="Name" ItemStyle-Width="120" />
    <asp:BoundField DataField="Country" HeaderText="Country" ItemStyle-Width="120" />
</Columns>
</asp:GridView>
<br />
<table border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse">
<tr>
    <td style="padding-bottom: 10px">
        Name:<br />
        <asp:TextBox ID="txtName" runat="server" />
    </td>
</tr>
<tr>
    <td style="padding-bottom: 10px">
        Country:<br />
        <asp:TextBox ID="txtCountry" runat="server" />
    </td>
</tr>
<tr>
    <td style="width: 100px">
        <asp:Button ID="btnAdd" runat="server" Text="Add" OnClick="Insert" />
    </td>
</tr>
</table>

You will need to import the following namespace.

using System.Data;

VB.Net

Imports System.Data

Binding the GridView utilizing an Empty DataTable

Originally a DataTable needs to be produced and it is saved inside the ViewState variable after which the BindGrid technique is executed which populates the GridView from your DataTable saved in ViewState variable.

Right here the principal cause to make use of ViewState variable is to preserve the GridView data across PostBacks.

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        DataTable dt = new DataTable();
        dt.Columns.AddRange(new DataColumn[2] {new DataColumn("Name"), new DataColumn("Country") });
        ViewState["Customers"] = dt;
        this.BindGrid();
    }
}
 
protected void BindGrid()
{
    GridView1.DataSource = (DataTable)ViewState["Customers"];
    GridView1.DataBind();
}

VB.Net

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
    If Not Me.IsPostBack Then
        Dim dt As New DataTable()
        dt.Columns.AddRange(New DataColumn(1) {New DataColumn("Name"), New DataColumn("Country")})
        ViewState("Customers") = dt
        Me.BindGrid()
    End If
End Sub
 
Protected Sub BindGrid()
    GridView1.DataSource = DirectCast(ViewState("Customers"), DataTable)
    GridView1.DataBind()
End Sub

Inserting data in GridView without using database in ASP.Net

First the DataTable is fetched from the ViewState variable and then a new Row is added to the DataTable by making use of the data from the TextBoxes.

Finally the DataTable is saved back in ViewState variable and the BindGrid method is executed which updates the GridView data.

protected void Insert(object sender, EventArgs e)
{
    DataTable dt = (DataTable)ViewState["Customers"];
    dt.Rows.Add(txtName.Text.Trim(), txtCountry.Text.Trim());
    ViewState["Customers"] = dt;
    this.BindGrid();
    txtName.Text = string.Empty;
    txtCountry.Text = string.Empty;
}

VB.Net

Protected Sub Insert(sender As Object, e As EventArgs)
    Dim dt As DataTable = DirectCast(ViewState("Customers"), DataTable)
    dt.Rows.Add(txtName.Text.Trim(), txtCountry.Text.Trim())
    ViewState("Customers") = dt
    Me.BindGrid()
    txtName.Text = String.Empty
    txtCountry.Text = String.Empty
End Sub
