VS 2010 : Filter Rows From Datagridview?
May 22, 2012
I have a datagridview and im using this code fill the table from a txt file.
Private Sub PopulateDataGridViewFromTXT(ByVal SFileName As String)
'Variables to store the count of rows and columns
Dim nRows As Long
[code]....
All that long list(more than 2000items) is loaded into my datagridview which have two columns named "ITEM" and "ID" With the code above the item from the id is splitted to each seperate column.I want to press a button and filter the table to show only swords for example or only spears.And the other thing is to make a search button to search for a specific item,which i suppose if the first thing is doable the second will be peace of cake..

But now my task is when i Type the text in the Combobox the related data should be filter in the DataGridView.If i type any letter in the Combbox the datagridview rows starts filter.
For Ex: Names are like 'Mali', 'Malu','Maal','Mouli'.
If i type 'M' letter in the Combobox then 4 rows Filter in the DataGridView.
If i Type 'Ma' then 3 rows ,
If i type 'Mal' then 2 rows,
If i type 'Mali' then 1 row.

Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.

I have a datagridview where I have added a filter. What I am trying to do if the user leaves the field blank I want all the records to show. The field I am filtering on is an integer. I thought I could declare a variable and if the field is blank include all records greater than 0. This would return all records as the number will never be below 0. I tried this but can't get it to work:
HTML
If txtFiltID.Text = "" Then
sSerialID > 0
Else
sSerialID = txtFiltID.Text
End If
'Refresh dgv on filtered criteria
Me.VJobLinesTableAdapter.FillByFilter(Me.DsJobs.vJobLines, sSerialNo)
It works fine if the user enters a value.

I am using vb.net express version. I have a datagridview which is popuated with data from an access database. I have all the data side working ok with the "Call Date" column set as datetime and sorted in date order assending within my application. I also have a monthviewcalender on the form and wish to filter the datagridview by the date selected in the monthviewcalender to show appointments i may have on that date.I have tried to populate the selected date into a textbox and use the following to filter:
AppointmentsBindingSource.Filter = String.Format("[Call Date] Like '" & TextBoxDate.Text) & "*'"
This causes a error. I have tried many different variants like:
AppointmentsBindingSource.Filter = ("[Call Date] Like '" & MonthCalendar1.SelectionRange.Start) & "*'"
The column is set as datetime in access and is system.datetime in the database explorers properties.

I am pulling data from a SQL server database into a dataset. The date are a DateTime type:
[Code]...
I can see the data in the field reads: 2011-09-09 15:56:29.667. I have tried to convert this by adding convert(varchar(10),DateFrom,103) which results in 09/09/2011 and then Custom Formated the DateTimePicker but still no success.I think I might be going completely off track here so can someone guide me on where I am going wrong here or the best way of doing this

I am trying to insert an initial line (0) into a datagridview (named params). The program will then read each cell in that row, pass them through a function and return values be placed into the next line (1). This will continue until one of the parameters reaches some set point. The problem that I am having is that when I try to insert a new line, it appears above the initial one and not below it like I would like it to.
Here's my code so far:
Private Sub HurricaneWinds_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim init_xrange() As Double = New Double() {0.0, 0.0, 0.0, 40.0, 0.0}
For i As Integer = 0 To 4
params(i, 0).Value = init_xrange(i)

My below is not an error. It just I need an alternative way of doing thing. I have a DataGridView which has a DataSource of DataTable on a Form. In this form, I have a 'Remove Selected' button which will remove all selected rows in DataGridView. And another 'Remove All' button which will remove all rows in DataGridView regardless of rows selected or not.

I not sure if this can be done with strings, but I have to ask. I have a BindingSource that I want to filter. I want to filter a column that has a data type string. I want to filter for all strings between "Cat" and "Monkey". Also,I would like to do the opposite, filter all strings that are NOT between "Cat" and "Elephant".For example, look at my datasource:
Ant
Cat
Dog
If I filter for strings between Cat and Monkey my filter would return: Cat, Dog, Elephant, Monkey?If I filter for strings NOT between Cat and Monkey my filter would return: Ant, Zebra ?Is this possible?I don't want it to be case sensitive, so I assume you would have to use Option Compare Text.

How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

I have a data bound datagridview on my form. I need the datagridview to sort by oldest date, and then return only the 150 oldest. The goal is to export the 150 rows with the oldest date to a .csv file and then update the date column to the current date for only those 150.
Here is what I have so far:
Dim appPath As String = Path.GetDirectoryName(Application.ExecutablePath)
Dim tdate As Date
tdate = Today.Date
'sort datelastemailed by oldest to be emailed first
DataGridView1.Sort(DateLastEmailedDataGridViewTextBoxColumn,
[Code] ....
I can get it filter by the column "status" and then sort by "datelastemailed". I can also get it to export only those 150 to the .csv file. My issue is that I need only those 150 to have their date column updated to today's date and then saved to the database. The only way I can see to get that done is to set a max number of rows for my databound datagridview and then loop through each row in the date column. How I can create a filter that limits results?

I have a DataGridView that uses a BindingSource that has a DataTable as it's DataSource. If I filter the DataGridView by using the BindingSource filter on a particular column, then I change a cell value in that same column the row disappears. For example, if I filter my "Shipped" column which contains CheckBoxes to only show True and then I set one of the CheckBoxes to False the row disappears from the DataGridView.
I do not want the row to disappear until the BindingSource filter is changed or removed. How can I suspend the BindingSource filter and then resume the filter if the filter has changed? I want it to work like MS Excel's filter. If you filter a column in Excel to only show cells that equal "Apple", then change the cell to "Banana" the row still shows, but if you change the filter the "Banana" row is removed. This how I want my BindingSource filter to work.
