asp.net - New line pressing "Return" key with asp:TextBox -



asp.net - New line pressing "Return" key with asp:TextBox -

i have asp:textbox in ajax popup panel. i've searched way create new line when user presses "enter/return" key, nil has worked far.

here textbox:

<asp:textbox id="commentairesavetxt" maxlength="4999" textmode="multiline" width="250px" height="100px" runat="server" />

i've read come in key defaults button without indication so, none of ajax panel's buttons events firing. far know, nil happens @ all. suspect there might kind of problem textbox beingness in panel.

here ajax:

<ajaxtoolkit:modalpopupextender id="btnsauvegarder_modalpopupextender" runat="server" targetcontrolid="dummysauvegarder" popupcontrolid="btnsauvegarder_modalpopupextender_pnl" cancelcontrolid="buttoncancel" backgroundcssclass="modalbackground" enabled="true" dynamicservicepath="" /> <asp:panel id="btnsauvegarder_modalpopupextender_pnl" style="display: none;" cssclass="modalpnl" runat="server" meta:resourcekey="btnsauvegarder_modalpopupextender_pnlresource1"> <table border="0"> <tr> <td> <img src="..\images\iconquestion.png" alt="question" /> <asp:textbox id="commentairesavetxt" maxlength="4999" rows="50" textmode="multiline" width="250px" height="100px" runat="server" /> </td> </tr> <tr> <td> <asp:label id="lblmessagesauvegarder" runat="server" meta:resourcekey="lblmessagesauvegarderresource1"> </asp:label> </td> </tr> </table> <div style="text-align: right;"> <asp:button id="buttonoksauvegarder" runat="server" text="ok" onclick="buttonoksauvegarder_click" meta:resourcekey="buttonokdeleteresource1" /> <asp:button id="buttoncancelsauvegarder" runat="server" text="cancel" meta:resourcekey="buttoncancelresource2" /> </div> </asp:panel>
