Hi folks
I have a aspx page that is linked to a master page.
The master page has three sections (top, LHS & footer) plus a content section.
The aspx page has a calendar control plus two buttons & two corresp text boxes. The buttons just read whatever date is selected and copies that to the corresp text box.
There are also some other controls as well on the page, but at this stage they don't do anything.
The problem I have is that every time one of the two buttons are clicked, it does what is intended, but it also causes a round trip to the server which is not what I want and is unnecessary at this point in time.
The dates that are written to the text boxes will eventually be used by the other unused controls that will extract info from a SQL DB based upon those dates.
Is there any way I can avoid a round trip to the server when the buttons are clicked?
Here is the markup for the aspx page:
CODE
<%@ Page Language="VB" MasterPageFile="~/CCFMaster1.master" AutoEventWireup="false" CodeFile="Sermons.aspx.vb" Inherits="Sermons" title="Sermons" %>
<asp:Content ID="Content1" ContentPlaceHolderID="bodyContentPlaceHolder" Runat="Server">
<script language="vbscript" runat="server">
Sub SetDateFrom(ByVal sender As Object, ByVal e As EventArgs)
Me.txtDateFrom.Text = Me.calChooseDate.SelectedDate.ToShortDateString
End Sub
Sub SetDateTo(ByVal sender As Object, ByVal e As EventArgs)
Me.txtDateTo.Text = Me.calChooseDate.SelectedDate.ToShortDateString
End Sub
</script>
If you have a look below, you will be able to see a Calendar and two buttons (From
& To). All you have to do is pick a date on the Calendar, ...
<br />
<br />
If you do that, then a drop down list box will be populated giving the dates of
the aactual sermons.<br />
<br />
<asp:Calendar ID="calChooseDate" runat="server" BackColor="White" BorderColor="#3366CC"
BorderWidth="1px" CellPadding="1" FirstDayOfWeek="Sunday" Font-Names="Verdana"
Font-Size="8pt" ForeColor="#003399" Height="200px" Width="271px">

</asp:Calendar>
<br />
<asp:Button ID="btnSetDateFrom" runat="server" Text="From" OnClick="SetDateFrom"/>

<br />

<asp:TextBox ID="txtDateTo" runat="server" Enabled="False"></asp:TextBox><br />
<br />
<asp:Button ID="btnShowSermonDates" runat="server" Text="Show Sermons" /><br />
<br />
<asp:DropDownList ID="ddlShowSermonDates" runat="server" AutoPostBack="True" Width="272px">
</asp:DropDownList><br />
<br />
<asp:DataList ID="ShowSermonDetails" runat="server" BackColor="White" BorderColor="#E7E7FF"
BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Horizontal">
<FooterStyle BackColor="#B5C7DE" ForeColor="#4A3C8C" />
<SelectedItemStyle BackColor="#738A9C" Font-Bold="True" ForeColor="#F7F7F7" />

<ItemStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" />
<HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#F7F7F7" />
</asp:DataList>
</asp:Content>
