AJAX :: Control Toolkit ComboBox SelectedValue / Does The Combobox Has As A Disadvantage That The Text Has To Be Unique
Apr 28, 2010
I have the following items bound to my combobox:
Value: 1, Text: SNS
Value: 2, Text: ING
Value: 3, Text: ING
Choosing value 1 results in a SelectedValue of 1
Choosing value 2 results in a SelectedValue of 2
Choosing value 3 results in a SelectedValue of 2
does the combobox has as a disadvantage that the Text has to be unique?

I just downloaded the latest ajax control toolkit and was trying to use ComboBox (as described on the samples page). However, I can't find it (tried to do reflection on the assembly as well).So is the ComboBox still in ajax control toolkit or it is removed or renamed etc?

I have 2 tables, call them stock and visit. Stock contains a list of standard products (code and description columns). Visit contains a list of products used during a visit (product description column amongst others). When a user adds a product to the visit table they can either select a standard product from the list or select a product code and amend the description, e.g. they could select "paint" and change the description to "blue paint". The new description will only be relevant in the Visit table. This all works fine.
I have an editable gridview which lists the products used during a visit. There is an Ajax control toolkit combo box in the EditItemTemplate which allows the user to select a different product. If the product exists in the Stock list then everything works
fine. If the user amended the description (e.g. changed "paint" to "blue paint" when they added the product to the Visit table I get the following error.
'ProductDescription' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
I presume this is because the amended description won't exist in the standard list of products. How do I add the amended description to the combo box list? I've tried using the RowEditing event but can't reference the combo box in the EditItemTemplate.I think what I want is something along the lines of [Code]....
Combobox markup below
<asp:ComboBox
ID="ProductDescription"
runat="server"
[code]...Answer in vb preferably.

I have a ajax combobox in my page, when i try to select an item from it i can select by typing in text and its selectedindexchanged event fires, but when that event is complete and when i try to select another item from the combobox it produces the following error:
could not complete operation due to error 800a025e,and an alert asks me if i want to debug it.If I press yes then i get this page:
// Name: AjaxControlToolkit.ComboBox.ComboBox.debug.js
// Assembly: AjaxControlToolkit
// Version: 3.0.30930.28736
// FileVersion: 3.0.30930.0
/// <reference name="MicrosoftAjax.js"/>
htmlfile: Could not complete the operation due to error 800a025e.
_setTextSelectionRange: function(textBox, selectionStart, selectionEnd) {
// set the selection range on the text box[code]....
The Weird thing about this is that the error does not occur on the development machine but only on the server.

I have problems with optimizing AJAX Control Toolkit. The specific problem is that 4800 records take about 30 seconds to bind in Internet Explorer (only 2 seconds in Opera & Firefox). I've tried anything, but I still can't improve the load time in IE.I've already enabled compression and caching, I'm using ToolkitScriptManager instead of ScriptManager. I've tried setting LoadScriptsBeforeUI and EnablePartialRendering to false, but it still doesn't help.
This is the query I use for binding.

I currently have an Instance of the ASP.net ajax control toolkit combo box residing in a field set with a style of position:releative applied. The control also sits in a very plain table.
There are two problems with the display of the list:
The list does not sit flush with the text box. In I.E. 7 (which is the majority of my target audience, intranet where IE7 is the company standard) the list display about 10px below the fieldset, which is what the bottom margin of the fieldset is set to. In FF 2.0 the list sits sinificantly lower and off-set to the right.
Below the filed set there is more content in a div, also with a style of position:relative applied. The list from the combo box displays behind the content of this div, which is obviously an issue.
Removing position: releative from the fieldset resolves the display issue of the combo box, but results in other unwanted display side effects.

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.

I have a combobox inside a hidden div which I use css display = none to make it invisible, but when I make the div visible by setting display = block, the combobox just show the input and its button and ul list all have css as display = 'none', visibility ='hidden'.
I can tell it is done by combobox inbuild javascript because I tried to use javascript to set the css manually with no luck. It is a bug of combobox. I spent a week to solve this, and our team put a lot trust on the toolkit.
Below is the code to reproduce the bug. When you run it, you can't see the dropdown:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</asp:ToolkitScriptManager>
<div id="d" style="display:none">
<asp:ComboBox ID="ComboBox1" runat="server">
<asp:ListItem>a</asp:ListItem>
<asp:ListItem>d</asp:ListItem>
<asp:ListItem>f</asp:ListItem>
</asp:ComboBox>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</div>
<div ID="Button1" runat="server" onclick="show();">click me</div>
<script type="text/javascript">
function show() {
var d = $get('d');
d.style.display = 'block';
}
</script>

I have a problem with the Ajax ComboBox from the Ajax Control ToolKit. When I want to erase the text in the ComboBox, I got this error:
"Microsoft JScript runtime error: '_optionListItems[...].text' is null or not an object". I only get this error when deleting the content of the Combox is the first action I do on the ComboBox. If I overwrite the text by entering something else before deleting this text, I got no error.

I have a problem with CascadingDropDown... I have two related comboboxes, where the second is a slave of the first (e.g. country the first, cities the second). What I want is that if I select one country from combobox 1 then the second must be "filtered" by that selection (it should display all the cities inside the selected country, and the actual CascadingDropDown implementation is OK), but if I leave the combobox 1 in the default option (e.g. "Please select a country") I want the second to display all the cities I have in the database. The problem is that when selecting default option for combobox 1 the second combobox is disabled and a postback to my webservice never occurs.

When the WebPage loads i would like for the Text to be cleared in Ajax ComboBox and/or DropDownList. However Setting the text to nothing or null doesn't seem to work. So I did some searching and found this...
[Code]....
Is there another way to clear the text other then adding a null item to the list? I don't really want the user to have a selection of "null", this seems like a hack job.

How do you refresh a combo box from clicking on something from another Combobox (using Visual Basic).
I don't want to use a button for this as i know it works that way by using .Databind() on the other combobox.
In access it is so easy by using the click event on a combo box but visual studio does not seem to use it.

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.

I am developing a web application in Visual Studio 2008 using ASP.NET with VB. I am using a ComboBox control from the AJAX Control ToolKit. The ComboBox gets populated from a database.On Page Load the focus is on the ComboBox control. The user can use the Down Arrow Key to drop the listed items, move up and down through it and on pressing Enter key on the highlighted item the other controls on the page (such as Text Box, DropDown List) get populated with data related with the selected item from the ComboBox on which the Enter key was pressed.What I want is that if somebody uses mouse on the ComboBox items and clicks any one item the data related to the clicked item should populate the other controls. This should also work on Lost Focus.So how do we write the Mouse Click and Lost Focus events for a ComboBox control from the AJAX Control TookKit.

I am using AJAX ComboBox control (or I can use simple ASP.NET DropDown Control it does not matter) in my form. What I do is, I bind combo box control to my database and retrieve client names:
[Code]....
But here is the problem. I want First and Last names to go into separate TextBox controls (txtFirstName and txtLastName). Now it inserts Last Name and Firts Name in txtLastName control. At the same time I would really like to keep LastName + FirstName together in Combo Box.
