View 1 RepliesI'm trying to use an ajax auto complete extender, but it's not working. I put a break point on the GetCompanyNames method in the web service, but it doesn't even hit the break point.
Here is my ajax autoextender

I'm trying to tie the AJAX autocomplete control to a textbox and pull the results from an sql database using VB. Anyone know how to do this? I found plenty of examples in c but I need to do it in VB. Here's code for C I guess but I can't figure out how to convert it to VB.

I don't want to use a webservice to populate an autocomplete extender on a textbox. In this case, it's where the user is entering email addresses and I don't want to make a trip to the database every single time. I'd much rather keep a collection in session state and 'bind' the autocomplete to that.
Is it possible to set ServicePath and/or ServiceMethod to something in the codebehind as opposed to a webservice?
In a page to create new user accounts, we have a database with a little of allowable users. To streamline getting the Email address of the new user correct, we want to use an AutoComplete extended textbox.Now I know that WebMethods are working because I have a cascading-drop-down tied to web methods in another page.As I'm just starting on this page, the code is simple.The page itself:
<cc1:ToolkitScriptManager ID="ScriptManager2" runat="server"/>
<p></p> Please enter new user's Email:
<asp:TextBox ID="txtUser" runat="server" />
<cc1:AutoCompleteExtender runat="server" ID="autUser" TargetControlID="txtUser"

I'm not even getting to the LogDebug statement. I've used all the same boilerplate code (Inherits, the 'WebService' tags, etc) that worked in the other WebMethod with the appropriate changes to the Class name but this really has me stumped.

View 3 RepliesI know how to call a simple old fashion asmx webservice webthod that returns a single value as a function return result. But what if I want to return multiple output params? My current approach is to separate the params by a dividing character and parse them on teh client. Is there a better way.

The VB.Net desktop app uses the IE browser control to navigate the web. When a normal page loads the document_complete event fires and I can read the resulting page and go from there. The issue I am having is that the page I am driving is written with AJAX, so the document complete event never fires. Furthermore, when you view the source of the page after it loaded a new portion via AJAX, it hasn't change.

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

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 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

View 5 RepliesI'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
View 1 RepliesI 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()

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 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

Note : This issue causes the application exit (sometimes) on Windows XP, but Doesn't affect on Windows 7
