I specified DropDownStyle = "DropDownList", so that users are not allowed to enter text that does not correspond to an item in the list.but my problem is that I can not typed text in the combobox even if I type the text that corresponds to an element of the list of combobox!!
<asp:ComboBox ID="Cmb_unitte_filtre" runat="server"
AutoCompleteMode="SuggestAppend"
DropDownStyle="DropDownList" MaxLength="0" AutoPostBack="False" ></asp:ComboBox>

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 have added a combobox to my page. Listview is updated based on selection from combobox. It is working great except it does not fire when Enter is pressed. User has to click on option from dropdown or has to press tab key to have Listview to populate. I want the user to be able type use arrow key to select option and then press the enter key for event to fire.
Using .net 3.5 and c#

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.

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 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 have a display problem when I try to use a ajax combobox inside a tab control: when my tab control loads on the page where the combobox is, everything works fine; however, if it loads on a another page, the you change to the page which contains the combobox, the right button (which opens the list of the combobox) isn't displayed at all.

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 have built a dataset named Transaction_Time.I called it on Page_Load
Transaction_Time tranTme = new Transaction_Time();
put it in the session.
Session["Transaction"] = tranTme;
Then I call that session and cast to dataset.
DataSet dstTranTime = (DataSet)Session["Transaction"];
I got the following error.Unable to cast object of type 'Transaction_Time' to type 'System.Data.DataSet'.
[InvalidCastException: Unable to cast object of type 'Transaction_Time' to type 'System.Data.DataSet'.]
Transaction_Time.Page_Load(Object sender, EventArgs e) in c:InetpubwwwrootWilliam29_11_2010Transaction_Time.aspx.cs:47

It is OK for some other pages. But for some page, it doesn't.
