Forms Data Controls :: Select Last Date In DropDown By Default?

Feb 24, 2010 07:50 AM

I have a date list in DropDown and there is no blank item in it. Dropdown item seems to be following:


DropDown is bounded by sqlDataSource.

If 04-02-2010 is the last date for today then I want to display 04-02-2010 by default in the dropdown if the page load.

We are updating data on daily basis. So on next day the date will be 05-02-2010 so when the data updated then 05-02-2010 should be shown iby default in the dropdown.

Select Last Item In Dropdown List

Jul 24, 2009 04:01 PM

I have a fairly simple question. I have a drop down list that is populated by a table in my sql database. I want to be able to go to the last record or item in the table and add one to the selected value, then insert that information in a textbox. Getting the selected value is easy, I just don't know how to automatically get the very last record. Since the drop down list is linked to the database, the number of items in the list changes almost daily.

Select Input Date As Default In JQuery Datepicker?

Nov 17 10 at 9:19

I have an ASP.NET application which uses JQuery datepicker for picking dates in some text boxes. For some date textboxes, I populate the date textbox from my database. When this textbox is clicked my JQuery datepicker appears, and it shows the current month with Today highlighted. This is fine for empty textboxes, however sometimes the text box is populated from the database. When the textbox is not empty I want the datepicker to show the textbox month and have the selected date to be the textbox date. Here's my current javascript code in my script header:

<script type="text/javascript">
$(function () {
dateFormat: 'dd-M-yy',
numberOfMonths: 2,
autoSize: true,
changeMonth: true,
changeYear: true,
showButtonPanel: true,
maxDate: 0

DropDownList / HTML Select List Default Selection?

Jul 18 10 at 18:53

For my ASP.NET page, in the code behind I load various items/options into a DropDownList but I do not set a default by assigning SelectedIndex. I notice for the postback SelectedIndex is set to 0, even if I never set focus to or changed the value in the DropDownList.

If not otherwise specified in the code behind or markup, will a default value of 0 be used for the SelectedIndex in a postback with a DropDownList? If yes, is this part of the HTML standard for selection lists, or is this just the way it is implemented for ASP.NET?

Web Forms :: Dropdown List - Default Value And OnSelectedIndexChanged Doesn't Fire

Jun 07, 2010 01:28 AM

I have a dropdown list that is populated by a dataset (Data being extracted from DB). Based on the selection made by the user I call OnSelectedIndexChanged, and populated the form with the relevent info. The problem I am having is the first item in the list is selected by default, so if the user selects this option OnSelectedIndexChanged does not fire. To work around this I add a default item to the dropdown list after populating it with the dataset as shown here;

jobStandardActList.SelectedIndex = 0;
jobStandardActList.SelectedValue =
"----Select an Item----");"";

This works fine, however if the user selects an item from the list, and then proceeds to selects the default item "----Select Item----" i receive an error. sys.webforms.pagerequestmanagersevererrorexception: an unknown error occured while processing the request on the server. The status code returned from the server was: 500

Jquery - Populating A Select List From An Autocomplete?

Sep 27 10 at 14:25

selecting a few items from a list of thousands. I have an autocomplete field that searches the db, and returns a name/id pair. This is working fine.

The next step is to preserve the selected IDs, and allow the user to remove some if needed. For this, I've been looking at using a select, and was hoping a UI something like that provided by this, but it doesn't work: it allows you to select items that already exist in the select, but doesn't work with a dynamically created select.

The final step is a traditional postback (using a submit button, this is in webforms) where I'll need to have access to the final list of IDs.

Page_load Fires Twice For UpdatePanel Refresh Whilst Having A JQuery Bound Change Event On A Dropdown List?

Sep 11 10 at 20:21

I've tried to wrap up my problem with a complete example below - the original problem is part of a jQuery plug-in that I'm writing to extend the behaviour of an ASP.NET ajax application I already have.

The aspx page below has one drop down list which is marked for auto post back. I've also bound a change event using jquery (which ultimately I will swap for a .live() event to maintain the binding after the update panel refresh.) The problem is, when the jQuery event is bound I see two ajax begin requests and page_loads fire but only one ddlTest_OnselectedIndexChanged event. One of the page loads is malformed too - the content-length states it's about 300 bytes long whilst the totalBytes is 0 and form data empty. This does not happen if I bind to the click event of a button.

why the erroneous page_load event is firing ?

DataSource Controls :: Insert A "Select User" Row In Linq For A Dropdown List?

Sep 07, 2010 02:47 AM

I'm new to Linq. I have searched and searched the web for a soluion, and can't find anything. I have a Linq query and I want to insert a row ("Select User") to the top before I pass it to the drop down list. I've been trying to use the Union but to now avail (it keeps telling me that my object doesn't support the Union method). My code, prior to attempting to inser a row, is very simple.

public SelectList DropDown_Users()
var context = new VivarianDataContext();
var query = from t in context.AspnetUsers
select new { t.UserId, t.LastName };
list = new SelectList(query.AsEnumerable(), "UserId", "LastName");
return list;

Now I try to insert a row and I found this on the internet and it seems to say that his solution will work. But it is filled with syntax errors. [URL]

I tried to implement it using the following code, but it doesn't compile.

public SelectList DropDown_Users()
SelectList list;
//get the original data
var context = new SQL2005633131VivarianDataContext();
var query = from t in context.AspnetUsers
select new { t.UserId, t.LastName };
//create a dummy table with an empty row
var AllUsers = new List<AspnetUsers>();
var BlankUser = new AspnetUsers()
{UserId=System.Guid.Empty, LastName="Select One"};
//use Union to join the data - ERRORS HERE
var newTable = AllUsers.Union(query);
list = new SelectList(newTable.AsEnumerable(), "UserId", "LastName");
return list;

Web Forms :: Can't Select Dropdown List Option If There Is Only One Option Returned

Jun 29, 2010 02:23 PM

I have a dynamic dropdown that is populated from sql. The user is supposed to select an option from the dropdown, then click a search button on the form to return some results based on that selection. It works fine if the dropdown gets populated with more than one record. However, if only one record is returned, that one record can't be selected. Whether you select it or just leave it alone since it's the only one, when you click the form button (search button), no results are returned b/c the dropdown selection must not be actually selected.

I've included the relevant code below. First the DDL, then the datasource, and finally the C# code in the if (!Page.IsPostBack)
