Add following code in aspx page under gridview:

ASP.NET

<asp:templatefield>
	<itemtemplate>
		<asp:fileupload id="FUDocs" runat="server" />                                             
		<asp:linkbutton id="btnUpload" runat="server" class="btn blue" text="Upload Document File" onclick="btnUpload_Click">
		</asp:linkbutton> 
	</itemtemplate>
</asp:templatefield>

Add following code in code-behind file:

C#

protected void btnUpload_Click(object sender, GridViewUpdateEventArgs e)   
{
	int index = e.RowIndex;
	GridViewRow row = (GridViewRow)gv1.Rows[index];  

	FileUpload fu = (FileUpload) row.FindControl("FUDocs");  

	if (fu.HasFile)  
	{
		string file = System.IO.Path.Combine(Server.MapPath("~/Images/"), fu.FileName);  
		fu.SaveAs(file);
		
		// Implement your logic
	}		
}

Try like this:

protected void btnUpload_Click(object sender, EventArgs e)
{
GridViewRow grdrow = (GridViewRow)((LinkButton)sender).NamingContainer;

FileUpload fu = (FileUpload)grdrow.FindControl("FUDocs");

if (fu.HasFile)
{
string file = System.IO.Path.Combine(Server.MapPath("~/Images/"), fu.FileName);
fu.SaveAs(file);

// Implement your logic
}
}
