I would do it something like this:

ASPX

<asp:GridView ID="YourGrid" 
              OnRowCommand="YourGrid_RowCommand"
              OnRowCreated="YourGrid_RowCreated"  
              runat="server">
  <Columns>
    <asp:TemplateField>
       <ItemTemplate>
           <asp:LinkButton ID="LinkButton2" runat="server" CommandName="View">
           <%#Eval("RSS_Title") %></asp:LinkButton>
       </ItemTemplate>
    </asp:TemplateField>
  </Columns>
</asp:GridView>

CS

protected void YourGrid_RowCommand(Object sender, GridViewCommandEventArgs e)
{
    if(e.CommandName=="View")
    {
      int index = Convert.ToInt32(e.CommandArgument);
    }
}
protected void YourGrid_RowCreated(Object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
      var LinkButton2 = (LinkButton)e.Row.FindControl("LinkButton2");
      LinkButton2.CommandArgument = e.Row.RowIndex.ToString();
    }

}

Please use the following:

<asp:LinkButton ID="LinkButton2" runat="server" CommandName="View" CommandArgument="1"><%#Eval("RSS_Title") %></asp:LinkButton>

I mean, add a CommandArgument.
