I want to filter data on the textchange event on listview so I use dataview to filter data. Issue in the below code is, I use dataview inside for each so that it checks only one condition that is last value only it takes, I want to check value in s1 with dataview and remaining value should bind with listview. E.g.: if I type an in textbox it should list all the item values starting with an value like anandha kumar, anna etc. Suppose I keep the value anandha kumar and anna in array s1. I should list all other values expect the array values like antony etc... in listview.
I'm having a little trouble trying figure out a way to filter specific file formats to only show in a Listview. For example I only want .txt files to show in a Listview and no other file formats. Is this achievable?I've had a look around the net but not found anything relevant to what I am trying to achieve.
I have a WPF ListView that I am trying to filter within a BackgroundWorker. My code is shown below:
Dim Worker As New BackgroundWorker AddHandler Worker.DoWork, AddressOf Me.FilterAsync Me.TextBoxText = Me.TextBox.Text Worker.RunWorkerAsync(Me.TextBox)
[code]....
This code runs through the filtering however it fails with an error "The calling thread cannot access this object because a different thread owns it." on the following line:
ListView.Filter = New Predicate(Of Object)(AddressOf Me.FindItemsAsync)
What would be the problem here? I can't seem to find any samples with filtering through the BackgroundWorker.
This is my line of codes. but it only compares to the equal match on the textbox. is there any way where i can match even just a keyword and will select all items with the same keyword that i type on textbox.[code]...
I have a listview and a textbox under it. Whenever a user input's text, I want the listview to filter. The code I have works, but the listview doesn't load the filtered data. I think it's because the listview has 2 columns of data that it's loading. [Code]

i am developing a point of sales system. currently i have my product code scanned and displayed in a listview. lets say that i have 5 product codes displayed in my first listview.

I am having a problem regarding to pass all the data on the listview from one form to another and add another columns. The purpose of my columns is that I want to put text from there because I am sending a mail but I want to get the status of my message if it failed or send and write it at every end of the rows.
I have an arraylist that holds a subset of names found in my database. I need to write a query to get a count of the people in the arraylist for certain sections i.e. There is a field "City" in my database from the people in the arraylist of names I want to know how many of them live in Chicago, how many live in New York etc.
how I might set up an sql statement to handle this. I think somehow I have to pass the subset of names to sql somehow.
Here is a sample how I am writing my sql in my code
Public Shared Function GetCAData(ByVal employeeName As String) As DataTable Dim strQuery As String = "SELECT EMPLID, EMPLNME, DISP_TYPE, BEGIN_DTE FROM Corr WHERE (EMPLNME = @name)"
[Code]....
I need a way to create a function using your sql statement to return a datatable object of names and the parameters would be city, and the List of names.
The above example isnt the sql I am looking for its just a skeleton of what the function would look like that I want to create.
So then you would use the function by iterating through all the cities passing in the same set of names each time in the fron end.
I have an idea, but i am not sure how to implement it with code.I have an application where a user can view current bookings for rooms.I have two datagridview controls, the first one shows the rooms and the second shows all my current bookings.What I want to be able to do or more the user, is click on a room and the current bookings for that room (datagridview1) to be shown in (datagridview2).What I think I need to do is apply a filter and a sort in a sub routine, then link my tables with a binding source.
If you dont mind can i have some codes that i can apply to my project? I am using Mysql database and the connection is ok. My problem is i want to filter data's on my database ex. i have 2 textboxes on my project Textbox1= Name Textbox2= Lastname and a database with 2 fields, Name,LName
All i want is if i type my name on the textbox1 and if i already had records in the database the textbox2 will be filled. ex. My record on my database is Erick for my Name and Juan for my LName once i type Erick on textbox1 the textbox2 will show Juan for my LastName??
I have a code which can get the MAX value of distinct "SYSID" field. Now, I plan to add a data filtering by time - Start and End time. I have tried but getting all sorts of error and can't get what I'm after for. So the program should do the data filtering (data >=starttime and data <=endtime) first before getting the max value of "SYSID"
Below is my Private Sub Get_Max() Dim ci As New CultureInfo(CultureInfo.InvariantCulture.LCID, True) Dim dtfi As New DateTimeFormatInfo() dtfi.ShortDatePattern = "MM/dd/yyyy" dtfi.ShortTimePattern = "hh.mm.ss" [Code] .....
I have a text file where the second column is numeric fields. All I'm trying to do is only show rows where the field in column 2 is in between txtmin.text and txtmax.text.The strange thing is that the following coding works.[code]
