I am not sure but i am looking for some help regarding values to be autosuggested from database when a user types in a textbox and the values should be a drop down list. I am using VB Net and it is something like the Autocomplete feature except that the values should be from database. I have not seen any links to this type of material but i just wanna know if it is possible. Infact i have found this type of stuff working with a combobox but havent found any for textbox.

txtBox has key up event that fires, if txBox.length = 2, a sql select to dataset for custom source of autocomplete.when user types in 2 letters it selects the 2 letters and when 3rd character is typed of course it erases the first 2 if you dont unselect..

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

View 2 RepliesThe First Question is not that important but you know that when you click on 'Favorites' in IE 8 a form thing comes up? Well I've been trying to do that for a long time but I can't figure out how. 2: In IE8 when you expand the window and collapse the window, the toolbars expand and collapse as well. How do I make my tool bars in my Web Browser do that. 3: I actually have a third question and that's, How do you make a horizantal scroll bar on your web browser control. (just like in Internet Explorer.)
View 4 RepliesI have used the command:
For Each Proc as process in process.getprocesses
Combobox1.Items.Add(Proc.MainWindowTitle)
to populate a combo box with the list of current process windows, however for every process that doesnt have a main window title there is a blank space, is there a way that I could tell it to not insert the item if it's mainwindowtitle field is blank?
have build some code which goes through the datasource finding records on what a user types, basically if the user types 'P' in the combobox it finds all records from FieldName with 'P' and if you type 'Portugal' it finds all records from the FieldName with 'Portugal, it all narrows down the search list say if there are to entries which match 'Portugal' the combox would only have to items in. The problem i am have is that when i bound the datasource back to the combobox every letter you type stays at Postion 0 of the combobox and doesn't move to the end of the letter as normally the combo works, does any one now how to get arround this problem.
At the moment i call my combobox search code from the keypress event of the combobox.This code works fine with recordsets in msaccess combobox but i cannot get it to work with the datasource of the combobox in vb.net Heres the code from the combobox keypress event:
Private Sub ComboBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles ComboSearch.KeyPress
Dim keyascii As Integer = AscW(e.KeyChar)
PhoneBookComboSearch(keyascii)
End Sub
Below is the code at the end of my keypress event send the datasource back to the combobox.
Dim adapter As New SqlClient.SqlDataAdapter(strSQL, conn)
Dim dt As New DataTable("MyTable")
Dim ds As New DataSet

I would like to maintain a list of all of the strings entered into a ComboBox across all uses of an application on a given PC, for use as the AutoCompleteSource for that ComboBox, i.e., I enter in "Fred" in the ComboBox, commit the data, close the application, reopen the application, reopen the ComboBox, type "F", receive the suggestion "Fred".Assuming I already have in place code to create and maintain such a list in memory and add new elements to it as they are entered into the ComboBox, etc., what do you suggest as the best way to save/load this data in between sessions?Possible complicating factors: This application will be deployed via OneClick deployment, and will search for updates online every time the application starts. I would prefer that if the application updates, the list still exists after the update has completed.

View 1 RepliesI have a combobox (cmbCharge1) that gets populated by a text file. Inside the combobox, the data inside is laid out like this: 41-1A-1303: EXPIRED REGISTRATION Now, autocomplete works fine, if I start typing in the statute (like the 41 part).

View 5 RepliesI have a small HR app.First step for user is to select the employee.I wanted a single combobox (autocomplete , drop-down), where the user can start typing either firstname lastname or nickname (these are 3 different fields in an SQL DB).At first, I would have the user check a checkbox near the combobox to select what they would be searching by (first, last, nick name), but then I thought - someone could probably help me with an example of not having to select which name type they are searching for, but just start typing and the combobox would autocomplete based on whichever name ?

Update 1: ButtonRenderer After searching all around, I found the ButtonRenderer class. It provides a DrawButton static/shared method which -- as the name implies -- draws the proper 3D button. I'm experimenting with it now.
