Question

Hoping someone can help. I am working on an aspx site, using the c# as the code behind. I have 3 input boxes, however when my cursor is in one of the input boxes, it seems to fire off the search_Click code which is fine if the cursor was in in the searchBox, but it seems to do it when the cursor is in the Username and Password Textbox. I dont have any javascript firing off this event, and what wanted to do was if user is in searchBox and hits enter, they fire the Search_Click otherwise if they are in either the username or password textbox and hit enter they fire off te code associated to login_Click. Hope that makes sense, anyone know why its firing the Response.Redirect even though I have no javascript/jquery teling it to.

//Front end aspx page
<input type="text" class="searchBox" autocomplete="off" id="searchBox" name="searchBox" runat="server" />
<asp:Button ID="searchBtn" class="searchBtn" runat="server" onclick="search_Click" />

<li>
  <asp:Label ID="UserNameLabel"  AssociatedControlID="UserName" runat="server" Text="Username :" CssClass="usernamelabel" />
  <asp:TextBox ID="UserName" runat="server" ValidationGroup="RegisterValidationGroup" CssClass="Username-Password" />                     
</li>
<li>
  <asp:Label ID="PasswordLabel"  AssociatedControlID="Password" runat="server" Text="Password :" CssClass="usernamelabel" />
  <asp:TextBox ID="Password" runat="server" ValidationGroup="RegisterValidationGroup" TextMode="Password" CssClass="Username-Password" />
</li>
<li>
  <asp:Button ID="loginBtn" class="loginBtn" Text="Login" runat="server" onclick="Login_Click" />
</li>



//C# Code behind
protected void search_Click(object sender, EventArgs e)
{
    Response.Redirect("/SearchResults.aspx?q=" + Server.UrlPathEncode(searchBox.Value));
}

Unless I’ve misunderstood your question, you can use the DefaultButton property of an asp:Panel object

For your login use something like… (untested)

<asp:Panel runat="server" DefaultButton="btnLogin">
  <asp:TextBox runat="server" id="txtUsername" />
  <asp:TextBox runat="server" id="txtPassword" TextMode="Password"/>
  <asp:Button runat="server" id="btnLogin" Text="Login" />
</asp:Panel>

And then for your search have… (untested)

<asp:Panel runat="server" DefaultButton="btnSearch">
  <asp:TextBox runat="server" id="txtSearch" />
  <asp:Button runat="server" id="btnSearch" />
</asp:Panel>

The idea behind this is that if the focus is on a asp:TextBox within the asp:Panel, pressing enter will initiate the DefaultButton. If you don’t want a particular one to cause a post-back to the server, then update the DefaultButton so that it automatically cancels, such as…

<asp:Button runat="server" id="btnSearch" OnClientClick="return false;" />
