From msdn, you should check this. GridView.SelectedIndexChanged event

void CustomersGridView_SelectedIndexChanged(Object sender, EventArgs e)
{
// Get the currently selected row using the SelectedRow property.
GridViewRow row = CustomersGridView.SelectedRow;

// Display the company name from the selected row.
// In this example, the third column (index 2) contains
// the company name.
MessageLabel.Text = "You selected " + row.Cells[2].Text + ".";
}

void CustomersGridView_SelectedIndexChanging(Object sender, GridViewSelectEventArgs e)
{

// Get the currently selected row. Because the SelectedIndexChanging event
// occurs before the select operation in the GridView control, the
// SelectedRow property cannot be used. Instead, use the Rows collection
// and the NewSelectedIndex property of the e argument passed to this 
// event handler.
GridViewRow row = CustomersGridView.Rows[e.NewSelectedIndex];

// You can cancel the select operation by using the Cancel
// property. For this example, if the user selects a customer with 
// the ID "ANATR", the select operation is canceled and an error message
// is displayed.
if (row.Cells[1].Text == "ANATR")
{

  e.Cancel = true;
  MessageLabel.Text = "You cannot select " + row.Cells[2].Text + ".";

}
}

Do these things

Step 1. Wire up a RowCommand Evnt to your GridView
Step 2. Inside that event at code-behind, do this 

if(e.CommandName.Equals("SendRequestCmd"))
{
    var clickedRow = ((Button)e.CommandSource).NamingContainer as GridViewRow;
    // now access the cells like this
    var clickedSLNo = clickedRow.cells[0].Text;
}

Update:

e.CommandSource definition

A instance of the System.Object class that represents the source of the command.

IButtonControl.CommandArgument definition

A control that implements the IButtonControl interface must implement the CommandArgument property and the CommandName property to indicate the argument and command name that are propagated to the Command event.
