AJAX Combobox Adding New Items Without Autopostback="true"

Jan 25, 2011

Buenos nachos, to be brief, my question is: is it possible to allow users to add new items to a combobox at runtime without having the autopostback property set to true? I understand it needs to postback if a new item is added, but I do not want the box to postback if the user simply selects a different value!

The tag I currently have is below. Without having the autopostback="true", the comboxbox doesn't allow the user to add new items to the box >_<' Any thoughts?

<ajx:ComboBox ID="cbCompany" runat="server" Width="226px" DropDownStyle="DropDown"
OnItemInserted="addCompany" AutoCompleteMode="SuggestAppend">
</ajx:ComboBox>

I know I could add a few more controls and do an easy workaround, just wondering if it is possible to do it this way.

How To Validate Inserted Items In AJAX Combobox Against Database

Nov 30, 2010

I wonder how to validate if a inserted item in a Combobox exists in a database during postback? If the item.text exists, a errormessage should notify the user that the item already exists in the database. If the item does not exists in the database a inserting should be done.

Should i use the customvalidator and create a servervalidationfunction that searches my databasetable for the item name?

Should i validate inside one of the two ComboBox control events, ItemInserting and ItemInserted?

After validating the existence i would like to validate if the inserting to the database was successfull.

Hitting Backspace In AJAX ComboBox Causes JavaScript Error?

Sep 16, 2010

I am using a ComboBox from the ASP.NET AJAX Toolkit (version for .NET 3.5) with values populated into its DataSource property.If I use my mouse to drop the combobox down and select a value, then highlight the value and click backspace, I get an error: Microsoft JScript runtime error: '_optionListItems[...].text' is null or not an objectMy DropDownStyle is set to "DropDown" so I should be able to have text in the control that does not exactly match one of the items in it. Therefore, I do not understand why I get this error. It seems to work perfectly otherwise.

AJAX :: Dynamically Populate A ComboBox Through Client-side Javascript?

Jul 29, 2009

I'm using the ComboBox control from the May 2009 release of the ASP.NET Ajax Control Toolkit.

I'd like to try and populate this ComboBox's list of options dynamically from the client-side Javascript (because I'm retrieving the data from the server based on the user's selection in another drop-down box). how to accomplish this? I tried this:

[Code]....

And it didn't work. The ComboBox just ended up with just one item (the first one) in the list, instead of all of them.

Choosing value 3 results in a SelectedValue of 2

AJAX :: ComboBox Input / When leave The Combobox It Adds To The Combox List?

Dec 3, 2010

I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).

I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.

Web Forms :: Add Items To Combobox From Popup Window?

Dec 27, 2010

I've a webform that has a formview in insertmode that among others has a combobox with a datasource. The problem is that user needs to have a way to add new items to combobox directly rather than having to go to mainteinance webform that deals with the info related with the table that feeds combobox. So I thought that I should have an update panel and put the combobox in there together with a button to open a popup window to add the new record, close when done and update combobox with newly added item.

In theory that's what I want. What I require are examples of how to do that in the best way. I thought first of using javascript but how do I know when the popup window was closed? how to trigger update panel?

Add Items From A ComboBox Or DropDownList; Similar To Shopping Cart?

Sep 19, 2009

I have two controls on my page; a ComboBox and a ListBox. I am confortable working with either, and I'm fine with setting up the SQLDataSource. I am wondering, though, how to click an item in the ComboBox, or an item in the ListBox, and get these items, which will be multiple items, into another page, and saving the items to that page, kind of like adding items to a shopping cart. This is not for commercial purposes though, and there is no 'shopping cart', but rather, I am trying to select items from lists to plan events. Is there a turotial online, either in written format or a video, that demonstrates how to do this?

AJAX :: Adding The 'multiple' Attribute To The Final Dropdown List And It Allows The Selection Of Multiple Items?

Mar 16, 2011

I am using the cascading dropdownlist controls from the Ajax toolkit. I have everything working perfectly and all of my select changes work. I have 3 related select boxes that all work great for single item select. What I need is for my last dropdownlist to allow for the selection of multiple items. I have tried adding the 'multiple' attribute to the final dropdown list and it allows the selection of multiple items but I cannot get the items when I post back, just a single item.

MVC :: Html Helpers With Javascript... Include Javascript In Helper But Avoid Adding Javascript Twice?

Jun 22, 2009

So I love MVC and I love Html Extensions and now I want to push it a little further... If I wanted to create something like an Html Helper that creates a javascripty style Calendar (for the sake of example as I don't want a calendar :-) how could I wrapper the javascript into the helper so that the consumer of the helper does not have to include the javascript on the page. MOST IMPORTANTLY though I want to have many instances of my calendar on the same page, if I put the Javascript in the Html Helper it will get written out 3 times to the page which is no good, so I am wondering how to get around this.

Essentially I want to know whether I can access the page's DOM whilst the Html Helper is being run so that:1) I can add javascript script/src tags (did I mention I don't want to have inline javascript :-)2) I can query the DOM to check whether the required script has already been included by a previous call the same Html Helper.This may be a no-brainer for some mvc/asp guru out there, it may also be the case that you can't access the DOM at runtime via c#

Javascript - ExtJS Combobox Sometimes Hides Behind Window Greyed Out?

Sep 27, 2010

So the code below is called when a user selects Save on an ExtJS popup modal window. This window ONLY contains a combobox. Now, sometimes when a user saves this, and then re-opens it later on, the combobox will appear BEHIND the window all grayed out, unable to get to. Other times, it will be fine and work, and no difference in events happening either time, just complete utter inconsistency.Does anyone know what this could be?

var changeProductOK = function() {
var win = getChangeProductWindow();
if (win.subProductId.getValue() == '') {

AJAX :: Highlighting The Text Of The Selected Item In Ajax Combobox?

Sep 26, 2010

Is there a way to programmatically select the entire string of the selected item in the AJAX Combobox?What I'm trying to do is bascially on a State/City selection.

1. User selects a State from the first combobox. This triggers the City combobox to be populated. The item(0) is "Select One:".

2. I want the entire "Select One:" to be hightlight as if the user had used their mouse and highlighted all the text.

The reason for this that I'd like the user to be able to start typing the city without needing to clear out the "Select One:" manually.

Web Forms :: Adding Colour Items To A Listbox?

Sep 8, 2008

I need to dynamically add a string sNewRow to a listbox. This is easy, I just use:

ListBox1.Items.Add(New ListItem(sNewRow)) in my VB.NET code.

However, sometimes when the code runs I would need the item to be added in a different colour, depending on some other condition. Does anybody know if there is a way of adding the new listitem to the listbox but at the same time declaring its colour to be (for example) green?
