Question

I have a textbox onin a masterpage which I’m using as a search box. When the user presses enter I want to redirect to an other page with the search terms in the url paramaters.

Trouble it only seems to work on pages that don’t have their own page_load subs.

            <div id="search-bar">
                <asp:TextBox ID="txtSearch" runat="server" Text=""></asp:TextBox>
                <asp:Button ID="btnSearch" runat="server" style="display:none"/>
            </div>

IN masterpage page_load:

    txtSearch.Attributes.Add("onKeyDown", "do_search(this)")

javascript function so that when user presses enter it calls btnSearch_Click

    function do_search() {
        if (event.keyCode == 13) {
            var invisibleButton = document.getElementById('<%=btnSearch.ClientID %>');
            __doPostBack(invisibleButton.name, '');
        }
    }


Protected Sub btnSearch_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSearch.Click
    If Trim(txtSearch.Text) <> "" Then
        Response.Redirect("viewall.aspx?q=" & txtSearch.Text, True)
    End If
End Sub

It only works on pages that don’t have a Page_load i.e. the response.redirect doesn’t fire on pages with a page_load.

Any ideas?

Ok, thanks for the answers above but didn’t seem to work. I finally got around this via this article…it seems a mysterious problem and is browser related.

3rd post down:

“I then tried wrapping the controls in a
Panel and set the Panel’s DefaultButton and that seemed to get it
working in IE.”

My page now is as follows:

                <asp:Panel ID="Panel1" runat="server" DefaultButton="btnSearch">
                    <asp:TextBox ID="txtSearch" runat="server" Text=""></asp:TextBox>
                    <asp:Button ID="btnSearch" runat="server" Style="display: none" />
                </asp:Panel>

…and it works! finally.
