Use the Defaultbutton Of the form

You can set your button as DefaultButton putting textbox and button in a panel

<asp:Panel ID="Panel1" runat="server" DefaultButton="Button1">
<asp:TextBox runat="server" ID="txtcity" ></asp:TextBox>
            <div id="resultDiv" runat="server>
            </div>
            <cc1:AutoCompleteExtender ID="txtcity_AutoCompleteExtender" runat="server" MinimumPrefixLength="1"

                ShowOnlyCurrentWordInCompletionListItem="true" CompletionSetCount="10" ServiceMethod="getcityName"

                ServicePath="webservice.asmx" CompletionInterval="1000" CompletionListElementID="resultDiv"

                EnableCaching="true" TargetControlID="txtcity">
            </cc1:AutoCompleteExtender>
            <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />

</asp:Panel>

<pre lang="text">
