Filter Out Unique Values
Jul 20, 2009is there a way to filter out unique values in a dataview or an array? I currently filter a dataview as such: [code] So now I have a dataview filtering the table, but can I further filter this data to find the unique instances of an item in this table? I eventually have to pass a portion of this table to an array, so if there is a way to find unique values in an array, I can use that.

View 1 RepliesFilter BindingSource By Greater And Less Than Values
Apr 11, 2012I thought I had this sussed until I then wanted to filter between two values or greater than or less than two values. I have searched and searched all over the web for this and I just go round in circles. This is so frustrating why is this so difficult to find something so basic (anyway that is my rant). I have something like this but am totally confused and do not understand what I am doing now: how I get this working in plain English.
Me.BindingSource.Filter = String.Format("DeliveryDate >= #{0:MMM/dd/yyyy}# And DeliveryDate <= #{1:MMM/dd/yyyy}#", dtpStartDelDate.Value.Date, dtpEndDelDate.Value.Date) _
& String.Format("JobID >= {0} AND JobID <= {1}", txtStartJobID.Text, txtEndJobID.Text)
If I run this with just the date range filter it works fine it is when I add the second filter for the Job ID range I get the following error; {"Syntax error: Missing operand after 'JobID' operator."}
So I it is this line I have the problem with:
String.Format("JobID >= {0} AND JobID <= {1}", txtStartJobID.Text, txtEndJobID.Text)

Change The Log File Filter (SourceSwitch ) Values At Run Time?
Aug 9, 2009I want to change the log file filtering at filtering at runtime. I am referring to the traceEventType in the following example.
My.Application.Log.WriteEntry(String.Format("{0:T} DeserilizeProperties", Now), _
TraceEventType.Verbose)
I have found the documentation that allows me to change it in the config file, but I need to do it at runtime. What I am trying to acheive is to allow a beta tester to turn on more detailed logging (according to the TraceEventType...) when encountering an issue in order to email me the log. And then switch back to less detail.TraceEventType.Information)
.Application.Log.WriteEntry(String.Format("{0:T} Send email", Now), TraceEventType.Information)
Format DataColumn Values In DataView.Filter Expression?
Jun 11, 2012I am trying to build a filter string for my DataView, but I have run into a problem. My underlying DataTable contains values that are formatted when displayed in my DataGridView.For example, if the DataColumn contains 1.52 and the DataGridViewColumn.DefaultCellStyle.Format = "n0" then 2 is displayed.So the user sees 2, then sets the DataView.RowFilter = "DataColumn = 2", and no DataRows are returned. Is there a way to format the DataColumn in the RowFilter string? For example, DataView.RowFilter = "FORMAT(DataColumn, "n0") IN (2, 4)". This filter string should return 3 rows. If not, can LINQ do this?
View 5 RepliesCompare Values In Datagridview With Values In Database Before Inserting Into Database
Dec 15, 2010I am building VB.NET application that takes data from text files that are exported from a legacy DOS program. These are written to a datatable and displayed in a datagridview. Right now my code simply loops through the datagridview and inserts the data into the database (SQL Server). There is a requirement now that the client number must be checked before the insert to see if it exists in the database. If it does, then the value of one field (tax rate) is checked against the value of the field in the datagridview. If there is a difference, then the rate is to be updated in the database and the data that was in the database is to be written to a history table for audit purposes. If the client number is not there, then we are to do the insert (which is already written). I want to know what is the most elegant and efficient solution for this problem.
I need to compare what is in the database table with what is in the datagridview, update the history table for records that exist, and then insert new records.
Filter DataGridView Results From ComboBox And DateTime Picker Values
May 28, 2010I'm trying to create a Windows form application which uses a few data grid views to pull data back from a SQL Server database. I've managed to get the data back okay from the tables but what I want to do is filter that data dynamically based on values input by the user from a combo box and a date time picker. Each of the data grids display production data for a machine but the combo box and date time picker will allow the data to be filtered by shift and date respectively - how to I pass the values of these to the SQL query returning the data?

Jan 19, 2011im just starting to work with some database stuff, and ive got data binding done but im a little stuck with filtering. Ive got a test project, which has
-- listbox (bound to column 2/firstname)
-- Combo box (Has items added, with the same names as the items in colunm 3. so it has 'RPG' and 'Puzzle')
Now what im trying to do is when the item in the combobox is changed say to 'RPG' only items in the db which have 'RPG' in the surname column are displayed in the listbox. Been Google'ing and reading but all i can find is examples relating to a dataview and i cant get them to work/adapt to my situation.

View 4 RepliesSQL DataBase Query / Filter At Runtime
Oct 28, 2011I'm trying to access the SQL DB I have designed within my project in Visual Basic 2010 (.NET code seems to work for me 99% of the time) at runtime so that a user can select a method by which to filter a DataGridView.I have a fantasy football draft application that fills the DGV from a Table Adapter. The database is named NFLPlayerDataBase.mdf, the dataset used to fill the DGV is TabNFLPlayers11BindingSource1, the table adapter is TabNFLPlayers11Table Adapter1. The DGV is dgvDraft. Idk if that helps at all.If the user wants to look at only RBs while making their draft choice, I want them to be able to select RB from a drop-down and have the DGV be filled with the query that selects only RBs from the table. I have the drop-down already set and am able to fill in the DGV when the form initializes. I just can't get it to fill with the query request for a specified position.The table I'm looking to use from the .mdf is tabNFLPlayers11 and the column header that will be searched through the filter is "Position." Options are QB/RB/WR/TE/K/DST and will be selected by the user from a drop-down.I cannot find a way to even open the connection whenever I change the value of the drop-down.

.net - Filter Wrong Database Records In A DataGridView Control?
Jul 5, 2011I have this database and I need to load it with a visual basic form in Visual Studio 2005.The database has 6 tables and they contain wrong data that I must filter when loading the database in the form.
A quick example:First table is Category, which has 3 fields (id, name, description). In one record I have 2a for id (a numeric only field) and in other record I have m1lk for name (a string only field).
When I click a button I load the database into a DataGridView control. How do I stop visual basic from loading into the DataGridView control those records that have invalid data (like in my example).
I have try with SQL queries using WHERE and LIKE, like in
SELECT IdCategoría, NombreCategoría, Descripción
FROM Categorías
WHERE (NombreCategoría LIKE '[!l]%') AND (IdCategoría LIKE '[!abcdefghijklmnñopqrstuvwxyz]')
but it's really difficult to filter things like Angel* and P3ter and Hood8, all at the same time..
