Adding Date/Time picker to your web form:

Adding Date/Time picker to your web form:

Using date picker for input to Date/Time field always made my applications more user friendly and never bothered me and the users about formatting the date/time. It is very simple to add date picker into any of your web forms or search pages in ASP. Net. The built in calendar control comes out very handy.

Drag and drop a Text box (TextBox1) into your form and you can add either the image of calendar or add text with hyperlink to date picker page next to it.

DatePicker

Now go to html view and change the codes as follows:

<asp:textbox id="TextBox1" style="Z-INDEX: 105; LEFT: 384px; POSITION: absolute; TOP: 56px" runat="server" Width="80px"></asp:textbox><STRONG> </STRONG><STRONG>  <A href="javascript:calendar_window=window.open('calendar1.aspx?formname=Form1.TextBox1','calendar_window','width=154,height=188');calendar_window.focus()"><STRONG><IMG style="Z-INDEX: 106; LEFT: 472px; POSITION: absolute; TOP: 56px" src="button_date.gif"></STRONG></A>

Now, create another webform, name it calendar1.aspx and add the following codes on html page.

Add these codes in the head portion of html page:

<script runat="server">

Private Sub Calendar1_SelectionChanged(sender As Object, e As System.EventArgs)

Dim strjscript as string = "<script language=""javascript"">"

strjscript = strjscript & "window.opener." & Httpcontext.Current.Request.Querystring("formname") & ".value = '" & Calendar1.SelectedDate & "';window.close();"

strjscript = strjscript & "</script" & ">" 'Don't Ask, Tool Bug

Literal1.text = strjscript

End Sub

Private Sub Calendar1_DayRender(sender As Object, e As System.Web.UI.WebControls.DayRenderEventArgs)

If e.Day.Date = datetime.now().tostring("d") Then

e.Cell.BackColor = System.Drawing.Color.LightGray

End If

End Sub

</script>

And add the following codes in the body:

<body leftmargin="0" topmargin="0">

<form runat="server" ID="Form1">

<asp:Calendar id="Calendar1" runat="server" OnSelectionChanged="Calendar1_SelectionChanged" OnDayRender="Calendar1_dayrender"

DayNameFormat="FirstLetter" BackColor="#FFFFCC" FirstDayOfWeek="Monday" BorderColor="#FFCC66"

ForeColor="#663399" Height="188px" Width="154px" BorderWidth="1px" Font-Size="8pt" Font-Names="Verdana"

ShowGridLines="True">

<TodayDayStyle ForeColor="White" BackColor="#FFCC66"></TodayDayStyle>

<SelectorStyle BackColor="#FFCC66"></SelectorStyle>

<NextPrevStyle Font-Size="9pt" ForeColor="#FFFFCC"></NextPrevStyle>

<DayHeaderStyle Height="1px" BackColor="#FFCC66"></DayHeaderStyle>

<SelectedDayStyle Font-Bold="True" BackColor="#CCCCFF"></SelectedDayStyle>

<TitleStyle Font-Size="9pt" Font-Bold="True" ForeColor="#FFFFCC" BackColor="#990000"></TitleStyle>

<OtherMonthDayStyle ForeColor="#CC9966"></OtherMonthDayStyle>

</asp:Calendar>

<asp:Literal id="Literal1" runat="server"></asp:Literal>

</form>

</body>

And that is it. You are ready to use your date picker to enter the date value through text box into your date/time field of database.

I tried this, and it would not work for asp.net 2.0

I finally figured it out. asp.net renames your controls when it renders the page. It also renames your form. So, when you send the literal Form1.TextBox1, that is not what asp.net 2.0 renders in the web browser. In reality, its 'aspnetForm' for Form1 (the form name) and '_ctl0_Main_TextBox1' for TextBox1.

When I altered the javascript in calendar1.SelectionChanged, it worked.

Title: Calendar failure in master Pages.
Name: Laserman

Comment:
Hi. We are using C# and had success until we decide to
use a Master Page for all our web pages.

The calendar will come up but then, after clicking the date,
the form1.txtFieldname is said to be null or not an object.
We tried adding the id of the content placeholder
asp:contentplaceholder
which did not work either. Can you help? Thanks.

Anyone try to make this work inside of a FormView control? I'm having a problem where it fails to close the calendar as well as failing to transfer the selected date back to the textbox. It's all inside of a FormView in the EditItemTemplate.

Comment:
make sure the textboxes that you have are of the same id as the line 'calendar1.aspx?formname=Form1.Textbox1{change this textbox name to the name of your textbox(s) ie i have 1 as txtfromDate so the line is 'calendar1.aspx?formname=Form1.txtfromDate}
That was how i solved my problem which was the same as you said urs was - hope it helps you

Title: For it to work in Firefox... Take 2

Sorry, I made a typo in the script in my last post. There is a dot after the word "document"

strjscript = strjscript & "window.opener.document." & Httpcontext.Current.Request.Querystring("formname") & ".value = '" & Calendar1.SelectedDate & "';window.close();"

By the way, your idea was realy helpfull. Keep up the good work!

Title: For it to work in Firefox...
Name: Eric Brousseau
Date: 2005-08-09 5:26:08 PM
Comment:
This code works well in Internet Explorer, but not in Firefox. If you want it to work, you must modify the JavaScript part from the calendar page like this:

strjscript = strjscript & "window.opener.document" & Httpcontext.Current.Request.Querystring("formname") & ".value = '" & Calendar1.SelectedDate & "';window.close();"

See, the "document" word is missing from your code and it crashes the FirefoxJavaScript compiler... Seems like IE is able to "understand" it both way.

And also, you should use RegisterStartupScript to add the JavaScript code to the WebForm in place of a Literal.
