asp.net - Modifying querystring on asp:hyperlink? -

my code looks this:

<asp:hyperlink id="hyperlink1" navigateurl="search.aspx?txtgraphicnumber=" target="_blank" runat="server">search related</asp:hyperlink> 

my querystring starts "txtgraphinumber=". i'd append querystring information in field on screen. field called txtgraphicnumber.

can like:

<asp:hyperlink id="hyperlink1" navigateurl="search.aspx?txtgraphicnumber=" + txtgraphicnumber + " " target="_blank" runat="server">search related</asp:hyperlink> 

you have 2 options achieve same:

option 1# code behind:

//assuming txtgraphicnumber textbox. hyperlink1.navigateurl += txtgraphicnumber.text;  

option 2# inlinecode:

<asp:hyperlink id="hyperlink1" navigateurl='<%="search.aspx?txtgraphicnumber=" +     txtgraphicnumber.value %>' target="_blank" runat="server">search related </asp:hyperlink>
