AJAX :: Control Toolkit Combobox Produces An Error 800a025e?
Oct 4, 2010
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:
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?
ajaxcontrol toolkit combobox control, a picture is worth than a lot of words so here is the picif you are not able to view then here is the link

the problem is the items text in the combox box is having a square beneath at the second character which is hindering the visibility of the list. but the square is not appearing in the text area.
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]....

<asp:ComboBox ID="ProductDescription" runat="server" [code]...Answer in vb preferably.
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.
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 am Getting the following error using the Numeric UpDown Control from Ajax Control Toolkit. Assembly 'AjaxControlToolkit, Version=3.0.30512.20315, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' contains a Web resource with name 'AjaxControlToolkit.NumericUpDown.NumericUpDownBehavior.debug.js', but does not contain an embedded resource with name 'AjaxControlToolkit.NumericUpDown.NumericUpDownBehavior.debug.js'.
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:
ive used the Ajax Control Toolkit in previous versions of VWD but for some reason im having trouble adding the Toolkit to the toolbox in this new version (2010) i have setup on my laptop, when i browse to and select the .dll file it gives me the error "Object reference not set to instance of an object" can anyone please help ive been trying to fix this issue for a little over an hour now.
This is the error i get in the browser. Update panel is workingBut Accordion,Rounded Corners Extender & much more controls does'nt workRESTARTING Visual Stuio does'nt help!
I am using both the AJAX Control Toolkit HTMLEditor and making AJAX WCF calls from my web form. Since we can only have one Script Manager per page, I am using this:
wanna use filtered TextBox ajax control in my simple page.I add a textbox in my page. And then i drag first script manager on my page and then drag filtered textBox in my textbox.But when i run my project i had an error like this picture..What is the problem? Where i doing mistake?
I just installed Ajax Toolkit. The controls are available in my Toolbox, but when I insert them in a page, Visual Studio underlines them with the error message "unknown server tag".
I googled the problem and found several ideas :
check if the DLL is in Bin folder check if ajaxToolKit tags prefix is registered in web.config and make sure I'm not using a different prefix in my pages check if the DLL is registered in the pages with <% @ Register ... %>
Unfortunately all of this is fine, but I still can't get the controls to work. Is something else missing ?
EDIT : My environment is ASP.Net 2.0, Ajax Extensions 1.0, Ajax Toolkit 1.0.20229, Visual Studio 2005

1. RadioButtonList Which is placed inside Update panel1 first. 2. GridView Which is placed inside Update panel2 second..and Gridview generated five Textboxes Dyanamically in which i have used autocomplete extender with one textbox. 3.

I have really stucked at a big problem using the AsyncFileUpload inside a TabContainer.

I cant understand what is causing this error ?
The Error that is highlighted in the code will be this:
