c# - How to bind grid in ASP.NET? -


i cant bind grid. dont know doing wrong, grid appears empty when run program.

here code ::

protected void page_load(object sender, eventargs e)     {         if (!ispostback)             this.bindgrid(this.gridview1);       }     private void bindgrid(gridview grid)     {         sqlcommand cmd = new sqlcommand("select * person", cn);         sqldataadapter da = new sqldataadapter(cmd);         datatable dt = new datatable();         da.fill(dt);         grid.datasource = dt;         grid.databind();     }   <body>     <form id="form1" runat="server">     <div style="margin-left: 240px">     <asp:gridview id="gridview1" runat="server" cellpadding="4" forecolor="#333333"              gridlines="none" width="856px" autogeneratecolumns = "false"              showfooter = "true" showheader="true" borderstyle="groove" captionalign="top"              horizontalalign="center" onrowdatabound="gridview1_rowdatabound" >         <rowstyle backcolor="#f7f6f3" forecolor="#333333" />         <columns>             <asp:boundfield headertext="id" />             <asp:boundfield headertext="first name" />             <asp:boundfield headertext="last name" />             <asp:boundfield headertext="home phone #" />             <asp:boundfield headertext="cell #" />             <asp:boundfield headertext="email address" />             <asp:boundfield headertext="nic #" />             <asp:templatefield headertext="action">             <itemtemplate>                 <asp:button id="button1" runat="server" text="button" />                 <asp:button id="button2" runat="server" text="button" />             </itemtemplate>          </asp:templatefield>     </columns>     <footerstyle backcolor="#5d7b9d" font-bold="true" forecolor="white"           />     <pagerstyle backcolor="#284775" forecolor="white" horizontalalign="center" />     <selectedrowstyle backcolor="#e2ded6" font-bold="true" forecolor="#333333" />     <headerstyle backcolor="#5d7b9d" font-bold="true" forecolor="white" />     <editrowstyle backcolor="#999999" />     <alternatingrowstyle backcolor="white" forecolor="#284775" /> </asp:gridview> </div>  </form> </body>

it looks aren't hooking databinding in bound fields example:

<asp:boundfield datafield="id" headertext="id"/>

you can find full example of how set databound field on msdn:here
