In this article I have explained with an example, how to get the cells values from Selected Row of GridView in ASP.Net using C# and VB.Net.
The GridView will be assigned an OnSelectedIndexChanged event handler and when the GridView Row is selected, the values of each Cell of the Selected GridView Row will be fetched and displayed.

HTML Markup

The HTML Markup consists of following controls:
GridView – For displaying data.

Columns

The GridView consists of BoundFIeld, TemplateField and ButtonField column.
TemplateField - The TemplateField column consists of ItemTemplate.
ItemTemplate - It consists of a Label.
ButtonField – It consists of a Select Button to select the GridView Row.
There is also a Label control below the GridView for displaying the Selected Row Cell values.
<asp:GridView ID="gvCustomers" runat="server" AutoGenerateColumns="false"
    OnSelectedIndexChanged="OnSelectedIndexChanged">
    <Columns>
        <asp:BoundField DataField="Name" HeaderText="Name" ItemStyle-Width="150" />
        <asp:TemplateField HeaderText="Country" ItemStyle-Width="150">
            <ItemTemplate>
                <asp:Label ID="lblCountry" runat="server" Text='<%# Eval("Country")%>'></asp:Label>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:ButtonField Text="Select" CommandName="Select" ItemStyle-Width="150" />
    </Columns>
</asp:GridView>
<br />
<u>Selected Row Values:</u>
<br />
<br />
<asp:Label ID="lblValues" runat="server" Text=""></asp:Label>
 
 

Namespaces

You will need to import the following namespaces.
C#
using System.Data;
 
VB.Net
Imports System.Data
 
 

Binding the ASP.Net GridView control

Inside the Page_Load event handler, an object of DataTable is created.
Then, three columns are added to the DataTable Columns collection using the AddRange method.
An Array of objects of type DataColumn is specified which will hold the name and the optional parameter Data Type i.e. the Type of the column.
Once the schema is ready i.e. all the columns are defined, some rows have been added using the Rows.Add method.
Finally, DataTable is assigned to the DataSource property of the GridView and the GridView is populated.
Note: For more details about dynamic DataTable please refer my article Create DataTable dynamically and bind to GridView in ASP.Net.
 
C#
protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        DataTable dt = new DataTable();
        dt.Columns.AddRange(new DataColumn[3] {
                            new DataColumn("Id"),
                            new DataColumn("Name"),
                            new DataColumn("Country") });
        dt.Rows.Add(1, "John Hammond", "United States");
        dt.Rows.Add(2, "Mudassar Khan", "India");
        dt.Rows.Add(3, "Suzanne Mathews", "France");
        dt.Rows.Add(4, "Robert Schidner", "Russia");
        gvCustomers.DataSource = dt;
        gvCustomers.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(2) {
                            New DataColumn("Id"),
                            New DataColumn("Name"),
                            New DataColumn("Country")})
        dt.Rows.Add(1, "John Hammond", "United States")
        dt.Rows.Add(2, "Mudassar Khan", "India")
        dt.Rows.Add(3, "Suzanne Mathews", "France")
        dt.Rows.Add(4,"Robert Schidner" , "Russia")
        gvCustomers.DataSource = dt
        gvCustomers.DataBind()
    End If
End Sub
 
 

Fetching Cell Values of GridView Selected Row in ASP.Net

Inside the SelectedIndexChanged event handler, the BoundField Cell value is extracted using the Cells property.
For extracting the value of the TemplateField Cell, first the Label control is referenced and then the value is extracted.
Finally, both the values are displayed in Label control.
C#
protected void OnSelectedIndexChanged(object sender, EventArgs e)
{
    //Accessing BoundField Column
    string name = gvCustomers.SelectedRow.Cells[0].Text;
 
    //Accessing TemplateField Column controls
    string country = (gvCustomers.SelectedRow.FindControl("lblCountry")as Label).Text;
 
     lblValues.Text = "<b>Name:</b> " + name + " <b>Country:</b> " + country;
}
 
VB.Net
Protected Sub OnSelectedIndexChanged(sender As Object, e As EventArgs)
    'Accessing BoundField Column
    Dim name As String = gvCustomers.SelectedRow.Cells(0).Text
 
    'Accessing TemplateField Column controls
    Dim country As String = TryCast(gvCustomers.SelectedRow.FindControl("lblCountry"), Label).Text
 
     lblValues.Text = "<b>Name:</b> " & name & " <b>Country:</b> " & country
End Sub
