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.
View 1 RepliesI have a situation. I know that backspace and delete don't work if we have asp textbox linked with MaskedEditExtender inChrome browser(may be other browsers have the same situation)but I've written some javascript to handle this.
<asp:TextBox .... onKeyDown="KeyDownHandler();"...../>
and in KeyDownHandler I check if it is backspace or delete key pressed and do manipulation with textbox text manually soat the end I have real normal text.And During editing text in textbox everything is fine but as soon as I get focus on another control .. text changes back (as it was before editing)What should I do to change the real text in textbox ? Now I am operating with textBox.value property but It seems MaskedEditExtender save this value or something like this.I found some property in MaskedEditExtender - MaskedEditExtender._LogicTextMask but if I change this .. it works only for particular mask of extender.....
I used below code for textbox
<cc1:MaskedEditExtender ID="MEE1" runat ="server"
TargetControlID="Txtprice"
Mask="999,999,999,999"
MessageValidatorTip="true"
MaskType="Number"
InputDirection="RightToLeft"
AcceptNegative="Left"
DisplayMoney="None"
ErrorTooltipEnabled="True" />
Here if I enter wrong digit and want clean wrong digit it doesn't clean I mean I should select all digit and type again

I want enter this number==500,256,325Â
if I enter 500,44 Â and want delete 44 and type correct digit(256) it doesn't clean it I press backspace but it doesn't clean it...

Why do I have to press the "Enable" button twice to enable a disabled ComboBox ?
I'm getting an error in all browsers with the ComboBox that in IE causes the user to not be able to enter data into any other field on the form. In Firefox it just throws an error but doesn't cause any problems.
The error is this:this.ajax__combobox_prototypes[i]._popupBehavior is null
I've got a few ComboBoxes on a page which worked fine before. I can't recall making any changes to the form but now I get an "Object Expected" javascript error when the page loads and the comboxes don't load/work.
On debugging from IE, the highlighted error is in MicrosoftAjax.js in the piece of code
var a=g?new h(g):new h
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 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'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.
in aspx i written as follows
<ajaxToolkit:ComboBox ID="cmbAddressAlias" runat="server" DropDownStyle="Simple" AutoCompleteMode="Suggest" CaseSensitive="false" AutoPostBack="true" RenderMode="Inline" Width="170px" CssClass="cmbProvince" OnSelectedIndexChanged="cmbAddressAlias_SelectedIndexChanged"> </ajaxToolkit:ComboBox>
it binding correctly(datasource dynamically binded) and it raises event too while changing index but it is not raising event when we manually clearing the combobox text..if currently combobox having text "ASP" then i manually select that entire text and using del key i am deleting but it is not raising event for me.. when i change index it automatically raising event...i need to raise event while combobox is empty...
i am using the combobox ajax control i in design time i am having an error:
there was an error rendering the control. Request is not available in the context.
I've got an AutoCompleteExtender on one of my pages, it seems to be working fine aside from this strange behaviour: Let's say I key in 2 characters, the suggestion list would display. When I press on backspace to delete those 2 characters, wait until the suggestion list to disappear, and re-enter those 2 characters, the suggestion list would no longer display (or sometimes would flicker for about a second after losing focus from the textbox) and I'll need to refresh the page just to get it working again.
However, if I do press backspace and delete those 2 characters but not let the suggestion list to disappear and re-enter new characters, it would continue displaying with correct suggestions. This behaviour seems to happen only in IE8, (although it works with IE8 using Compatibility View and Firefox)... My code is almost the same as the sample on this site except for the animations, and the service looks up in a database table.

I am working on an app and have added masked edits to some of the textboxes. On Google Chrome v6.0.472.62 the backspace button is inoperative along with the delete button. I have found no method around this. It also functions incorrectly on the ajax toolkit website: [URL]
Chrome is fairly popular and I doubt I can use this code with this issue.
I was just typing on an old site of mine that requires the constant contact method that uses threading and an update panel to prevent users from being logged out since despite setting the timeout period in web.config to what mathematically should be millions of minutes people still seem to get logged out after like 5 minutes. I tried the web service method, but it was ineffective.
The constant contact with an update panel accomplishes its primary objective well, however when a user clicks on their keyboards back button at the wrong time they get redirected to the previous page and if they click the forward button in their browser the page contains none of their typed data.
Is there a way to override whatever causes the backspace button to do this?
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.
the following is the Markup of my page based on a master page. its a log in page with a default login control.

View 6 RepliesIn Key Press Event i have put the logic of search in textbox, when i press enter key it will take the values from textbox and brings the data in DataGrid.
In another event of GotFocus there is an logic of autocompletestring collection from Table. If i type a in that textbox it will shows all the suggested string in that.
If i comment the logic of GotFocus Event for textbox for autocomplete then only then Key Press events work else its not working. I dont know why its happening.
So GotFocus loic creates the problem.

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.
