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 have a problem with my coding to autocomplete textbox. nothings happen
Dim col As New AutoCompleteStringCollection NewDataSet("select * from tbluser") If ds.Tables("0").Rows.Count > 0 Then For i = 0 To ds.Tables("0").Rows.Count - 1
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 want to make a textbox suggest all possible inputs based on a certain column in my database. for example, i have a country column in the database and i want my textbox to display all countries from my database column that starts with P when i type it and so on
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 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 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. ( What a browser does with already visited pages )
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 want a textbox to have autocomplete. I want the completion to be based off of text that has been previously entered into the textbox. My method of saving seems to work but when i close the program and re run it the autocomplete suggestions arent there anymore.
I have a textbox, a sql database, a binding source bound to the sql database. I can use auto-complete mode of the textbox with custom strings and it suggests in in a drop down form as the user types in a textbox. How can I use autocomplete mode with datasaved in different records of a field using the bindingsource?
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
I have datagridview containing 4 columns with 2 combobox. With the initial loading of datagridview I could select an item with the combobox, but when I tried to select an item with other combobox I've got an error showing "System.ArgumentException:
I have a datagrid and I have imported it to my project under vb.net language, and the database is MS access any way in this datagrid one table call "Employees" ID - Name - Nationality - Job title and what I want is when I write the ID number of the Employee, all the other details automatically comes upon to his ID number.
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") Dim conn As SqlConnection = New SqlConnection
[code]....
I didnt include the IsReusable when posting, but that is there. why it doesnt like multiple values but will display one lone value?
** Edit ** I just looked in Firebug and it is getting a response but just not displaying it. My implementation of this is pretty simple so far, nothing to fancy.
I have a combo box with autocomplete binded to a database. I would like it to return, or at least assign to variables specific columns in the same row to a label when I press the button. I read something about Tag and Text in the label section but couldnt quite figure it out.
I have a ComboBox in my WinForm which has data from SQL server (used LINQ to bring up the data). I'd like to have an option just like AutoComplete in VB.NET but not only by the first letter but for a search LIKE.
I'm having troubles with my datagridview. Id like to use a combobox that you could type into and (as you are typing) would update the drop down list with the ability to use wildcardsThe list is populated with a table in my database. I know how to do this using just a combobox on a form, but I'm still learning everything with datagridviews.Is there a way to do this with a combobox in datagridview? If not, is there a way to do it any other way (i.e. using a textbox and having something pop up like the autocomplete windows)? I really would like to have the ability to use wildcards with this
I would like a fulltext autocomplete functionality for a Combobox. Built-in autocomplete only filters those items, that match the written text from the first letter. Is there any 3rd party components that has fulltext autocomplete? Or do I need to make functions myself?
i have a combobox with autocomplete to listitems it works very fine if i wrote the first letter it suggests a list of items that starts with this letter. i need to make it work if i write any part of the word not only the first letter?
