.net - Jquery Autocomplete From An Array In Session?
Mar 21, 2011
I will be storing an array in session that will contain data entered by the user (id numbers used to search in several different areas of the application) I then want to return the values in this array that is residing in session as auto complete selections.
Getting the array into session and updating it is the easy part, getting it from session into the autocomplete isn't as much so. I'd rather use the array to do the auto complete instead of converting to json.
I've tried using '<%= SESSION("MEMBER_SEARCH_ARRAY") %>' as the source for the autocomplete but no dice.
I am attempting to create a ASP .Net (VB.Net) custom control for an auto-complete drop down that uses jQuery auto-complete.The basic flow is the consumer of the control will set some properties (such as the data source) which will then be injected as javascript to initialize the autocomplete.There are a lot of pieces involved so i may have missed posting some of the code, please comment if you think something is missing and i will add it.the consumer's code behind (PreInit event):
myDropDown.DataCallback = "testFunc";
the DataCallback property in the control:
Public Property DataCallback As String
the options object creation and javascript injection in the control code behind (PreRender event):
Dim _serializer As New JavaScriptSerializer() Dim optionsObject As New Dictionary(Of String, Object) optionsObject.Add("source", DataCallback)
[code]....
when i debug into the initialize function, i see options has one property, source, with the string "testFunc" as it's value. what i need is for source's value to be testFunc (not as a string) so it can be executed as a callback in autocomplete instead of autocomplete thinking it is a URL.
Dim dt As DataTable = MyClass.DatabaseRecordsetCall() Dim str(dt.Rows.Count) As String
If dt IsNot Nothing AndAlso dt.Rows.Count > 0 Then For Each row As DataRow In dt.Rows
str.SetValue(row.Item(0).ToString, dt.Rows.IndexOf(row)) Next End If
This is the code I am using to populate a string array to use as an autocomplete source for a textbox.The datatable has 17 rows in it. However, it creates the string array with a length of 18.Just an FYI, if you try to use an autocomplete source that contains a value = nothing, it will cause your application to crash.No, not cause an exception which could be dealt with, but a solid inexplicable, pull your hair out, scream and curse because you cannot figure it out crash. The microsoft message that comes up references the file browseui.dll.The above code as is, will generate an extra array value whose value WILL equal nothing and cause this crash to happen.
I am storing an array of a custom serializable class in session on my site. When a page on the site changes, suddenly it renders them invalid, and tells me that it can't cast the type to it's own type. I assume the class version numbers are changing or something?!
I'm not trying to redesign this whole process.
Unable to cast object of type 'ShipmentPackages[]' to type 'ShipmentPackages[]'.

I am storing a session variable that a user types into a textbox. With their valid input, their session gets created and they get a little more functionality than the regular end users of the site.I was wondering if it is possible to find a way to add someone's session variable to the end of a URL. This way we can email a link to one of our clients, they click it, and their session has automatically begun. They already have the textbox to enter their code into, but I was told that it would be much easier for the users to just click a link that will start their session.
On startup of my software which i developed in vb.net, it connects to mssql server. I want to have session id or session number of the connection with mssql. I'm sure it is unique number and i want to use this session in my software for different purposes. My question is
1. is there anything like session id or session unique number when you connection mssql server
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: DataGridViewComboBoxCell Value is not valid. To replace this default dialog please handle the dataerror event" . When ever I click it's always shows this message.
I have some code that calls to Active Directory and gets a list of users then adds them into a ComboBox.
I would like to extend this feature by allowing the combo box to autocomplete when a user starts to type.
Ive read a few articles but they seem to be based on data coming from SQL server but none on Active Directory. Could anyone assist by advising how i could go about this?

i am new to VB.net and i am now exploring the some of the controls in VB.net i have a problem with regards to autocomplete in VB.net 2005 in my textbox, i set the AutoCompleteMode to "SuggestAppend" and i have filled my AutoCompleteCustomSource.
the autocomplete works but with one simple problem.... i have a problem with regards to "/" character
in my attachment when you type "A" and your succeeding characters is with "/" character... it will not display the rest of the characters..for example, "A. VALVE 1/2 X 3/4" in textbox will display "A. VALVE 1/".
Is there any workaround with this problem? I hope that you can help me with regards to my problem...
I have a combobox that is populated with movies with a number corresponding to where it is held in our archives ie. "451 How The Grinch Stole Christmas"What I would really like to do is have an autocomplete routine that would make it possible NOT to have autocomplete only work on the first character. As it stands, with Visual Studio's native autocomplete if my combobox is populated by:
Apple Smoothie Banana Puree Crayon Colors
[code]....
and I type "Pu" I will get only "Pure Energy" as an autocomplete result. I would like it so that typing "Pu" would return Pure Energy & Banana Puree.
I'm struggling to meet a demand from my supervisors.Basically there are places in our project where there is a big selection of options. The most concrete example is choosing a city in the world. The items are hundreds of thousands.Using standard winforms controls and properties, one can search through a list fast.The problem is that we're using a concatenation of city&district name for all the items. Essentially PREFIX autotomplete works but does not work as needed. The task is to filter and show items by any given string in any part of the item. Essentially a FULL TEXT search in the combobox.Does anyone have an idea about switching autocomplete sources in runtime relatively qiuckly and handling the suggest/suggestappend event?
I have a couple of texbox and combobox controls that are bound to a dataset. I can scroll this with the a bindingnavigator. But I want to have the combobox do autocomplete from the dataset. For example, if i type a "D" in the combobox bound to the 'ClientName' column of the 'ClientInfo' table,i want the comcobox to display all (or maybe the top 20) names that start with a "D". If i then type an "E" I would like the list to show all names starting with "De" and so on.
I have tried to bind the 'autocompletesource' of the combobox to the 'ClientName' column, but that did not appear to do anything.I am reasonably experienced with VB .Net, but totally new to database and data centric applications.
I have a datagridview in vb 2010 and in one of the columns I populate a combobox with items from a database. With autosuggest, I filter the list to select an item. But autosuggest only works on the beginning of an item. I would like to search in each item. For example typing 'bank', I would like to select from:
I am building a autocomplete on my textbox. Really simple and it works really fine. But I like to do the next thing. When there is a match in the list and I will click on it. then i like to have a function.
For example
Private Sub ListItems_click(ByVal sender As Object, ByVal e As System.EventArgs) MsgBox("test") End Sub
I use combo boxes with the Autocomplete turned on (Source = ListItems and Mode= SuggestAndApplend). The problem is that if the user stops typing for two seconds and then continues typing, the Autocomplete starts matching only on a new characters being typed. For example, I have a list with two items: "apple" and "please". I type "ap", then pause for a couple seconds and then continue typing "ple". I want the list to match on "apple" but instead it matches on "please". I'm looking for a property or some way to set the length of time the control resets the matching. Do you know if one exists?
I have an application that I am completing that has several AutoComplete TextBoxes, but I can't get them ti work. My program is in Visual Basic 2010 with an SQL Server Express R2 database.
The database Query is:
[Code]...
When I run the program, nothing happens, my guess is that the problem is in the properties.
I have a combox that is run-time bound to a table that is run-time built and populated from a text file. I have set the combobox autocomplete mode to suggest and the source to list items, but only the 1st item will work. Ok so here's the code:
Private Sub SetStateComboBox() 'set autocomplete for combobox state_cmbx.AutoCompleteMode = AutoCompleteMode.SuggestAppend[code]....
The file is a text file with a list of the 50 states and their abbreviations in the format : stateName - abbr.Now what happens is the data is displayed correctly, but when I begin to type a letter for the autocomplete the only letter that shows anything is the "a" and it will only show the very first item in the text file.Everything else does not display with the autocomplete, but does show in the list. I have tried variations such as adding the data as items like this:
Private Sub SetStateComboBox() 'set autocomplete for combobox state_cmbx.AutoCompleteMode = AutoCompleteMode.SuggestAppend[code]....
This way does not allow any autocomplete when I begin typing but everything is in the list. I've also tried converting the table to a customautocompletestring and still the same results.The only way that I have been able to get it to work is be entering each state as an item: state_cmbx.items.add("Michigan - MI"), then it works correctly.Also the combobox dropdownstyle is set to dropdown, and I'm using visual studio 2010 ultimate and coding using VB.
Can we make a particular column in DataGrid to behave like text box AutoComplete mode?In the GUI, am planning that the user will select a ProductName and will enter the details in the datagrid.The problem I am facing is am not able to set datagrid column to AutoComplete.If I use Textbox or Combobox for the purpose, am not able to enter the selected content into the datagrid because the datagrid is binded to a dataset.
I have a vb.net form with a textbox on it set to autocomplete custom collection from a database. Is there an event that fires when a user finds the value they want from the autocomplete list?
