Forms :: Textbox That Is Filled Using Auto-complete?
Apr 2, 2009
I have a textbox that is filled using autocomplete. The autocomplete is a globally accessible sub that I use for textboxes and (I guess) comboboxes.My problem is that the autocomplete sub takes several seconds to fill the textbox. Is there some way my code could be improved? (The code below takes three seconds to fill for 288 autocomplete entries, which I don't think should be a lot for this kind of functionality.)
My best bet is that the autosorcecollection has to redraw itself every time an entry is added, and that causes the delay, but I'm not sure.Apart from taking time I think this global function is really handy, so feel free to use!

I have auto complete functionality in combo box ,it works properly but there is little issue ,I made the suggestion list appear for the text length more than 3 chars ,but the list appears after the length of 4 char (when user enters the fifth char of the text) which means when the code executed in the first time the list doesn't appear here is the code in Text_Changed Event
Private Sub TxtItem_TextChanged(sender As System.Object, e As System.EventArgs) Handles TxtItem.TextChanged
If Trim(TxtItem.Text) <> "" And Trim(TxtItem.Text).Length > 3 Then
'Autocomplete
[code].....
Note : This issue causes the application exit (sometimes) on Windows XP, but Doesn't affect on Windows 7

What is the best approximation algorithm to implement full-text fuzzy search. For example we have a dropdownlist with the following data (from SQL datasource):
Company Policy
Product Catelog
Our Partners
Now I want to replace it with an autocomplete textbox, such that when the letter "p" is typed the list shows all three results. It should start matching the first letter of the first word or second word and so on. Also, it should highlight or make the matched letters bold in the suggestions dropdown.Is there a readymade control for ASP.NET (with JS or jQuery) to deliver all the aforementioned functionality? Otherwise if I have to implement it, is there a tutorial/blog which point me in the right direction?

I'm using the AutoComplete function of a TextBox to suggest values from a database to the user. This works almost as expected. However, I do have two questions that I can't seem to find the answer to...
1) Is it possible to change the function that selects the items to display in the AutoComplete dropdown such that it will also select strings that match anywhere else than at the beginning? For example, when I type 'apple' I want that to match 'Apple' but also 'I have an apple!'.
2) Is it possible to change that same function to sort the options? (In my case based on how often they exist in the database.)

I implemented auto complete in vb.net textbox , but there is an issue that when user types something in text box the auto complete suggestion list blinks and disappears like if the focus changed
here is the code:
Dim Bl As New ItemBL
Dim suggestions = DAL.DisplayLikeNameList(Trim(MyTextBox.Text))
Dim MySource As New AutoCompleteStringCollection()
[code]....
I believe the problem in Mdi form because it has timer code executed after the above code :
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
LblDateAndTime.Text = Now
End Sub
Note: the auto complete code is executed in a child form not in the Mdi Form , what do you suggest to keep suggestions list "sticky" as the user writing in the text box ?

I have a textbox in form1 and I want to enable the autocomplete with the items in Listbox1 in Form2. For example if the users enter in textbox1 something that is similar to any of the items in Listbox1, I would like it to be shown in a list below the textbox.

I have a small problem with my AutoComplete Textbox in that it doesn't replace what I type with the item from the drop down list. This is hard to explain so I will start off with the AutoComplete of the combobox and how it works.
If I create a combobox with the following listitems (pay attention to case as this is the actual problem)
Item1
Item2
Production1
Production2
Now I can set my AutocompleteSource to ListItems and when I begin typing into a combobox I get a list of matches (Using SuggestAppend)So if I type i (lowercase) I get a list containing Item1 and Item2 with tem1 added and selected for overtyping in my combobox text. Now if I press Tab or Enter, My combobox.text is updated with Item1 with the proper casing from the list even though I typed a lowercase i. This is not how it is working in the textbox. Using the following code:
Dim mySource As New AutoCompleteStringCollection
mySource.AddRange({"Item1", "Item2", "Production1", "ProductionItem2"})
TextBox1.AutoCompleteCustomSource = mySource
TextBox1.AutoCompleteSource = AutoCompleteSource.CustomSource
TextBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend
When I begin typing in the textbox, again, the list drops down. And again, when I type a lowercase i, I get a list containing Item1 and Item2 with tem1 filled in to my textbox. Now if I press enter or tab, my textbox is filled with item1 instead of Item1 as it did with the combobox.
My question is:Is there a way to ensure that the text in the textbox matches the actual case of the item in the customsource? I can click the item in the dropdown and it appears in the textbox just fine. But I don't want to force my users to have to do that.

I'd like to create a standard AutocompleteTextBox that works with a timer, such that there is only one BackgroundWorker working on searching - if the user entered a few more keystrokes, but the old search is still running - that search shall be canceled gracefuly (via CancelAsync), and as soon as its canceled the new search will begin.

I'm trying to make the autocomplete work on a list of items entered into a textbox separated by semicolons. I have a list of authors the user can choose from and it autocompletes as they type the name no problem, but what I'd like to do is after the user types a name followed by a semicolon, the autocomplete works on the next name and so on.e.g., Smith, John; Eastwood, Clint?

I am trying to set autocomplete for a textbox using data from a column in a table an Access database. Some of those records in the table have no values. I have set the AutoComplete Mode property to SuggestAppend and the AutoCompleteSource property to CustomSource. When I run the application nothing happens when I type into the textbox. The dataset is called DatabaseDataSet and the table name in the database is called Simple and the specific field/colum is called SIM_TAG1
'Create customsource for tag textboxes to suggest tag terms based on what is in database
Dim oTag As New AutoCompleteStringCollection()
For Each term As DatabaseDataSet.SIMPLERow In Me.DatabaseDataSet.SIMPLE

I would like the autocomplete list of a textbox to be the words that the user has previously typed and saved. For example if they enter "dog", "cat" and "fish" I want the autocomplete suggests to show these three options. So far my Code only shows the last user input. I expect there is an easy solution as I am new to all this, but I can't seem to find it on my own.

So I was reading a bit on AutoComplete of textboxes in VB.NET, but I can't really understand where these are stored? Is it a fully built in feature, or do I have to write some code for it to work? I've found the AutoCompleteMode and AutoCompleteSource properties of textboxes.But I want to append whatever I've written in the textbox to the autocomplete source. Do I connect the source to My.Settings or something

Im currently diving into jquery autocomplete for the first time. To start off with, I had a .net handler calling out to a mssql db and pulling last names. That worked great.However when I try to add additional values it simply doesnt work. The code being used in the handler is as follows.
Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim prefixText As String = context.Request.QueryString("term")

I didnt include the IsReusable when posting, but that is there. why it doesnt like multiple values but will display one lone value?
