Append QueryString To PostBackUrl Attribute In ASP.NET Web Forms LinkButton Control Inside GridView Control
There was a question raised in the forum on how to append query string to a PostbackUrl attribute in an ASP.NET LinkButton inside the template field of a GridView control. To answer that, one possible solution is to set the PostBackUrl with String.Format() method where you can include the desired query string of that url. 1 2 3 4 <asp:LinkButton ID= "lnkProductPage" runat= "server" PostBackUrl= '<%# String.Format("ProductPage.aspx?Id={0}", Eval("ID"))%>' CausesValidation= "false" Text= '<%# Eval("ID")%>' > </asp:LinkButton>
