datepicker works in standalone aspx file but not when associated with a Master Page VS Studio 2010 C#

in Using jQuery UI • 4 years ago

I'm working with code from a supplier who created the shell of a working website. I need to add a date range to one of the reports.

The web site has a Master Page (ASP.NET)where it uses the form tag that begins and ends on the Master Page.

The page where I want to add two date fields is started and ended with <asp:Content></asp:Content>. The fields for the two dates work on a separate aspx page where I can use the form tag and there is no <asp:Content> section. That exact code does not work between the <asp:Content> and </asp:Content> tags in the web site code.

Here is my separate calendar.aspx. This code does not work between <asp:Content> tags and a Master Page already have a form tag which causes VS 2010 c# to disallow the one in this code.

ASP mangles IDs, so you can't use them directly in the JavaScript code. Either insert the ID generated by ASP or look for the given ID at the end of the actual ID. Something like this, I think:

$(function() {
$('input[id$="SearchFromdateTextBox"],input[id$="SearchToDateTextBox"]').datepicker({
changeMonth: true,
changeYear: true
});
});

Thank you. I have the calendars showing up now when I enter the fields intended for date entry. Much to learn since they handed me this project to finish.

Your answer gives me an alternative to what I found on another posting:

$(document).ready(function() {
$('#<%= SearchFromdateTextBox.ClientID %>').datepicker({
changeMonth: true,
changeYear: true
});

That's the code for the first option I mentioned: "insert the ID generated by ASP".

to kbwood.au. Re-reading your post, it was definitely the first I read to identify the answer. I'm very new to JQuery UI and also learned about the ability to apply the datepicker to more than one field. I've marked it as the best answer. Thanks again.
