AJAX :: Use AutoComplete ComboBox In A DataTable And GridView
Nov 23, 2010
I am using an Active Directory DirectorySearcher to populate a DataTable and GridView so I can make a sort of "Phone List", very similar to the following post: [URL] What I also want to do is use a ComboBox with Append AutoComplete mode to easily filter this phonelist. However, what datasource am I supposed to bind the ComboBox to?
I need to fill Combox only after the page loaded. same like AutocompleteExtender. My Page have more than 10 ComboBox and it will be good for my project if only ComboBox can populated when use make setfocus. if there is something like AutoCompleteExtender for ComboBox?
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.
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...

In my recent project i have used auotcomplete extender. it work well with simple textbox
Now i want to use it with gridview , in my application for fill product details for any order i have used gridview if user wants to add multiple products so by making class create list of objects of that class and bind to gridview i am able to add row. in that row one field stock code now on that i want to use autocomplete extender as per below code
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 am having problems getting the Autocomplete extender to work within a grid view which is contained inside an update panel.Outside of the update panel the auto complete works fine, but when placed inside the 'EditItemTemplate' tags on my gridview it does not display any results. Debugging revealed that the webservice is being called and values returned, but they are not being displayed within the grid view.
how to join two datatable datas into one datatable to show in one gridview
i.e in 1 datatable i have username and pwd and in another datatable i have that user details. how to show all these in one datatable to get those values display in gridview(asp.net)
I am going to outline my setup then where i am failing
UpdatePanel1 - Contents : 3 textboxes and AddButton UpdatePanel2 - Contents : 1 GridView and SubmitButton
AddButton adds new row to DataTable with data from textboxes, binds DataTable to GridView SubmitButton sends data to database. The Adding of a row works to add the row to the gridview, but it won't add a second or third and so on, only adds the 1. SubmitButton belives the DataTable that GridView is databound to is null and won't send anything to the database. How can i get the datatable to persist between the two update panels? Do i use Sessions as my storage location? Page
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.
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 was trying to use CssClass="WindowsStyle" with the following CSS. Its working fine if WindowsXP theme is selected but when the theme is changed it looks odd (different from other controls).
I wish to have the ComboBox similar to the style used by other controls. Please give me the solution for this issue.
I understand the issue is with the button(background-image: url(../images/windows-arrow.gif);) but what could be the alternate solution?CSS used
I want to create a dll Only for Ajax ComboBox. I mean I want when I add this dll in toolbax, I able to drag Ajax Combo Box control on web form.Ajax provided source code & JavaScript files for ComboBox but how I can Create a dll from this.
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
