Dot Net Code Snippets

Here We have to discuss about how to set the default button in Masterpage
for ex: in Master i have Search_textbox and Search_button when the user enter some text in the Textbox and pres Enter so the Search_button should trigger..

Html Code

<asp:Panel ID="SearchStyle_Panel" runat="server" width="100%">
<table width="100%" border="0" cellspacing="0" cellpadding="0">
                        <tr>
                              <td width="188" align="right" valign="middle" class="white_text">
                                   SEARCH
                              </td>
                               <td width="235" align="right" valign="middle">
                                   <asp:TextBox ID="search_textbox" runat="server" value="ENTER KEYWORD" onfocus="if (this.value == 'ENTER KEYWORD') {this.value = '';}"
                                      onblur="if (this.value == '') {this.value = 'ENTER KEYWORD';}" CssClass="textbox"></asp:TextBox>
                               </td>
                             <td width="5" align="right" valign="middle">
                          </td>
                           <td width="40" align="right" valign="bottom">
                                 <asp:Button ID="search_button" runat="server" Text="GO" CssClass="go_btn"/>
                              </td>
                           </tr>
                      </table>
                     </asp:Panel>

since the button is nested inside of a control that implememts INamingContainer, its UniqueId will not match its server ID

for that reason, you should set the DefaultButton property in code.

myPanel.DefaultButton = myButton.UniqueId

then on page_load

SearchStyle_Panel.DefaultButton = search_button.UniqueID
