JQuery :: TextboxWaterMarkExtender And Datepicker - TextBox Losing Value On PostBack?
Feb 25, 2011
I have a textbox that uses TextboxWaterMarkExtender and jquery-ui's datepicker plugin.Upon postback, my textbox is losing the value selected from jquery datepicker.Below is the sample code to see the behavior. Is there anyway I can make my textbox to retain selected value on postback?One thing to note is, if I use jquery watermark plugin, it does postback the value. But for certain reasons, I think I plan to use AjaxControlToolkit.

I've got an application that uses jquery ui datepicker on an asp.net textbox control.The control is working as intended, but I've noticed that when you postback from a server call (via submit button), the entered value gets lost in the application.Was wondering if you all have experienced this? And what measures that you have to do to prevent this?Here is my code:HTML:
<asp:TextBox runat="server" ID="txtCallsMadeFrom" class="field" EnableViewState="true">
JQuery:
var callsMadeFromId = '#<%=txtCallsMadeFrom.ClientID %>';
jQuery(callsMadeFromId).datepicker({ showOn: "button", buttonImage: "../images/calendar.gif", altFormat: 'dd/mm/yy', buttonImageOnly: true, onSelect: function () { } });

everytime the user selects a date from my datepicker the for some reason instead of staying focused on the are the date picker is in it scrolls to the top of the page.
Heres the function located at the bottom of my asp.net page under the
<script>
$(function() {
$( "#<%= pissued1.ClientID %>" ).datepicker();
});
</script>
This is the code.
<td align="left" colspan="2">
<strong>
<asp:Label ID="labdi1" runat="server" Text="*Date Issued:"></asp:Label>
<asp:RequiredFieldValidator ID="p1divalidate" runat="server" ControlToValidate="pissued1"
ErrorMessage="You Forgot The">*</asp:RequiredFieldValidator><br />
</strong>
<asp:TextBox ID="pissued1" runat="server" Width="45%"></asp:TextBox>
</td>
and also on postback my datepickers stop working. For example i have a dropdownlist that causes postback and if the user uses the drop downlist then the datepickers stop working

In a page I have a link; clicking on it opens a dialog and sets a textbox value for that dialog.
However, once I click on submit in that dialog, the textbox value is null.
Link:
<a href="#" onclick="javascript:expand('https://me.yahoo.com');
jQuery('#openiddialog').dialog('open'); return false;">
<img id="yahoo" class="spacehw" src="/Content/Images/spacer.gif" /></a>

I have some textboxes (in an UpdatePanel in a ModalPopup in a User Control) that look like this:
<asp:TextBox ID="exampleTextBox" runat="server" MaxLength="10"
CssClass="datepicker" ReadOnly=true
Text='<%# Bind("ExampleDateField") %>' Width="77px">
</asp:TextBox>
I also have some jQuery (imported from file on the Master page) that hooks up the jQuery DatePickers like so:
function pageLoad() {
$(".datepicker").unbind();
$(".datepicker").datepicker({
changeMonth: true,
changeYear: true,
showOtherMonths: true,
selectOtherMonths: true,
beforeShowDay: $.datepicker.noWeekends,
showOn: 'button',
buttonImage: '../Resources/Images/Calendar_scheduleHS.gif',
buttonImageOnly: true,
buttonText: 'Select a Date'
});
}
The DatePickers appear correctly, even after a postback. The problem is that the value of the textboxes is not changed when a postback occurs. This is very odd since the textbox shows the selected date in the browser. However, the value of the textbox is still the date that the textbox originally had, not the date selected from the datepicker.

I am using the jQuery Datepicker without any problem for TextBox controls that are non-templated. However, I am unable to get the datepicker to work with a TextBox that is in an EditItemTemplate of a ListView control. My latest attempt is to get a handle on this textbox by CSS class name "DateControl"?

I have a gridview that I can't for the life of me get the datepicker calender to pop up for. I've been using the datepicker for months very successfully for a variety of textboxes on the page and inside of formviews but this is the first time I've tried using with gridview. I didn't expect any issues however can't seem to find anything to work. I have searched the forums for 2 days and attempted any suggestions found within the solutions to no avail. I've tried using the CSS to link the datepicker but everything stopped working when I changed the code and my page which uses a css style already got all distorted looking.Here is my gridview (only included a part b/c it is large and am only having problem with the datepicker for the date completed text box)
[Code]....
Here are my scripts at the bottom of my page...the problem one is the "txtActual_date_completed". Please note that I am using 2 other datepickers on this page in fiter criteria for my gridview and they are working just fine.

I have read a lot of post and seen some solutions to this; however, nothing seems to work for me. I have a gridview inside an update panel and when the user clicks on the edit link the row goes into edit mode. when the user clicks into the text box specified for the date nothing happens. here is what my JS looks like and the gridview row i am working with. i have tried the CSS selector and the ID selector with no luck......I also have a date picker working great on my page, but it is not inside a gridview or an update panel....
<script type="text/javascript">
$(document).ready(function () {
$(".show").datepicker({ dateFormat: 'yy-mm-dd', showOtherMonths: true });

I haven't been able to find anything on the net about this yet. A project that used to work fine all of a sudden started having trouble with a couple users. The TextBoxWatermarkExtenders for these users are now always firing the TextChanged event of the textboxes they are assigned to for every postback. I don't think this is what they are supposed to do. They didn't use to do this. Has anyone else experienced this? I can add code to ignore these unintentional events, but I would like to know why all of a sudden the change in behavior.

I'm completely new to JQuery and MVC. I'm working on a pet project that uses both to learn them and I've hit my first snag.
I have a date field and I want to add the JQuery datepicker to the UI. Here is what I have done:
Added <script src="../../Scripts/jquery-1.3.2.min.js" type="text/javascript"></script>
to the site.master
Inside my Create.aspx (View), I have
<asp:Content ID="Create" ContentPlaceHolderID="MainContent" runat="server">
<h2>
Create a Task</h2>
<% Html.RenderPartial("TaskForm"); %>
</asp:Content>
and inside "TaskForm" (a user control) I have:
<label for="dDueDate">
Due Date</label>
<%= Html.TextBox("dDueDate",(Model.Task.TaskID > 0 ? string.Format("{0:g}",Model.Task.DueDate) : DateTime.Today.ToString("MM/dd/yyyy"))) %>
<script type="text/javascript">
$(document).ready(function() {
$("#dDueDate").datepicker();
});
</script>
As you can see, the above checks to see if a task has an id > 0 (we're not creating a new one) if it does, it uses the date on the task, if not it defaults to today. I would expect the datepicker UI element to show up, but instead I get:
"Microsoft JScript runtime error: Object doesn't support this property or method" on the $("#dDueDate").datepicker();
It is probably a very simple mistake, so don't over-analyze. As I said, this is the first time I've dealt with MVC or JQuery so I'm lost as to where to start.

I have been using session variables in my asp.net application for passing the next property:
[DefaultValue(true)]
public bool IsModificationMode
{
get
{
return (bool)Session["ModificationMode"];
}
set { Session["ModificationMode"] = value; }
}
In the PageLoad, I set it's value.
Now after the Postback, I am losing it's value having a a NullReferenceException

I have an upload control (csv file) of which I use the stream to retrieve data in a datatable that I then bind to a datagrid, sitting in a repeater control.I have to bind more than one record to the repeater, therefore I need to find a way of storing the stream for each binding, so that I can bind it to the datagrid again, via itemdatabound event of repeater.
I have tried storing the stream in the repeater's datatable but on each postback, the content of the stream gets lost. The stream still exists, but its length is set to 0.I have tried storing it in a session object, but again it is reset to 0.
I have tried using viewstate but I get a xmlserialization error. Saying IXmlSerialization is not implemented.I am desperate to find a work around as I am feeling the pressure at work.

I have a ascx page where I am using a hidden field to store the value of a the drop down box as it is generated using a google address finder. My problem is that when I try to store the value directly in the hidden field :
hfDdlVerifyID.Value = ddlVerifySS.SelectedValue;
in the event of a button click, the value is stored but on postback is lost again. Whereas, if i try to use Scriptmanager to do it, nothing is stored.
getBuild.AppendLine("$get('" + hfDdlVerifyID.ClientID + "').value = $get('" + ddlVerifySS.ClientID + ").value;");
ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "storeHidden", getBuild.ToString(), true);
// Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "storeHidden", getBuild.ToString(), true);
string test = hfDdlVerifyID.Value.ToString();

I have a form with a update panel. This posts the form and validates it. Returning a errorMessage string of any invalid field such as "Field xyz is a required field, Field abc needs to be a quantity"
When I enter incorrect date it posts back fine and displays the text in a div at the bottom of the page which the update panel is aimed at to update. (and only this it should be changing)
This works but the second time I hit say (say i enter invalid data twice) the Complete form will disappear leaving me with just the banner of the site and the error message that is returned.
Ive tried commenting out the entire of the code post back so that the button doesn't actually do anything but it still has the same problem(of course this time it wouldnt have a error message created)
So i can only think it is something to do with the updatepanel itself and how it works but i have been staring at this for ages and have no more ideas!

I have this date value fetch from a Controller but when I use jQuery Datepicker with validation, the output is not good.The validation is to check if the value is less than or greater than today's date. JQuery Datepicker works well.If I select a date two days from now using datepicker, the validation error won't occur. [:(]
ViewData("DateToday") = Date.Now.ToShortDateString()

I am in beginner level on developing web pages. I was coding on desktop applications and as you know it is easy to say that web applications are extremely different than desktop applications.
I wonder why data are lost between postbacks.???? And what is the best way not to lose the data belonging to a specific control (especially gridview). Session or viewstate or anything else?

Never had this happen before. I just upgraded my site from 3.5 to 4.0. Here's the scenario:
1.) I have a literal on a web form, in an UpdatePanel.
2.) On PostBack, the Literal's "Text" property loses it's value. The ViewState is enabled throughout the page. Further, I changed the Literal to a label and it also has this problem. The TextBox's appear to keep their values.
3.) If I remove all of the Ajax controls (which currently is just the UpdatePanel and the ScriptManager) then the Literal control keeps it's value through PostBacks.
4.) There is no client side JavaScript where I'm manually changing the values of these controls. They are only editted in the server side events.
I have read that setting the AutomaticDataBind property in the web.config could remedy this but I can't find any documentation on it and I don't know where to put it in the web.config to even try it.

I am using the AJAX Contol Toolkit and 4 CascadingDropDown extenders with an ODBC connection in a Web Service. The original load of values in each level works great. I then use these values to set the create the SQL for the SelectCommand for a Gridview.
The problem I am having is that when I submit the page to perform the search, the first 2 dropdowns repopulate and set the selected index accordingly, but the 3rd dropdown does not retain its selected value. It does populate with the values, but the selected value does not get set.
The correct values are available for the SelectCommand which returns the correct values.
