<asp:datagrid id="dg1" runat="server" horizontalalign="center" autogeneratecolumns="false" width="850" allowsorting="true" onsortcommand="lawsortevent" showfooter="true" onitemdatabound="lawdg_itemdatabound" footerstyle-font-bold="true" >   <columns>   <asp:boundcolumn datafield="id" headertext="" headerstyle-horizontalalign="center" itemstyle-horizontalalign="center" />   <asp:boundcolumn datafield="afecategory" sortexpression="afecategory" headertext="code" headerstyle-horizontalalign="center" itemstyle-horizontalalign="right" />   <asp:boundcolumn datafield="transdate" dataformatstring="{0:mm/dd/yyyy}" sortexpression="transdate" headertext="date" headerstyle-horizontalalign="center" itemstyle-horizontalalign="center" />   <asp:boundcolumn datafield="company" sortexpression="company" headertext="vendor" headerstyle-horizontalalign="center" itemstyle-horizontalalign="center" />   <asp:boundcolumn datafield="description" sortexpression="description" headertext="desc" headerstyle-horizontalalign="center" itemstyle-horizontalalign="left" />   <asp:boundcolumn datafield="systemtype" sortexpression="systemtype" headertext="system" headerstyle-horizontalalign="center" itemstyle-horizontalalign="center" />   <asp:boundcolumn datafield="apinvoice" sortexpression="apinvoice" headertext="ap inv" headerstyle-horizontalalign="center" itemstyle-horizontalalign="right" />   <asp:boundcolumn datafield="amount" sortexpression="amount" dataformatstring="{0:c}" headertext="total" headerstyle-horizontalalign="center" itemstyle-horizontalalign="right"  />     <asp:templatecolumn headertext="" itemstyle-horizontalalign="center" >       <itemtemplate>         <asp:imagebutton id="btnviewinvoice" runat="server"           imageurl="/images/glass2.png"            oncommand="dgviewinvoice"            commandargument='<%# databinder.eval(container.dataitem, "apinvoice") %>'            commandname='<%# databinder.eval(container.dataitem, "vendornum") %>'            alternatetext="view invoice"            visible='<%# (databinder.eval(container.dataitem, "systemtype") <> "gl") %>'          />       </itemtemplate>     </asp:templatecolumn>   </columns> </asp:datagrid>

my issue imagebutton - don't know how write in c#, because i'm not sure trying do.

the closest found explaining of what's deal databinder.eval , container.dataitem?, i've been trying different ways of changing text make work last 30 minutes no success.

everytime change text, error message changes tried differently.

i rock.

i figured out.

<asp:templatecolumn headertext="" itemstyle-horizontalalign="center" >   <itemtemplate>     <asp:imagebutton id="btnviewinvoice" runat="server"       imageurl="/images/glass2.png"        oncommand="dgviewinvoice"        commandargument='<%# eval("apinvoice") %>'        commandname='<%# eval("vendornum") %>'        alternatetext="view invoice"        visible='<%# eval("systemtype") != "gl") %>'      />   </itemtemplate> </asp:templatecolumn>
