I have a datatable and I apply a filter to the defaultview.rowfilter property of that datatable. If I then loop through the rows collection of the datatable, will I only be able to see those rows that the filter applies to, or will it loop through all the rows?

I think my question is discriptive, or as Microsoft in the Documentation for Data Grid the question is, How do I have a combo box column display a sub set of data based upon the value of a different combo box column?

Brand new to VB 2008 Express, but have done some work in VB 6. Not sure what I'm missing, but here goes. I have two comboboxes linked to an Access 2007 database. One box lists the names of the States in the US.
This is what I used for the Table Adapter Configuration Wizard for the combobox "State" SELECT ST_UID, ST_NAME FROM STATE
For the combobox County I used: SELECT ST_UID, CTY_NAME FROM COUNTY ST_UID is an Integer.
I created a label with a bound value to STATE.ST_UID so that when a user selects the name of a state from the State box the appropriate ST_UID populates the label, (i.e, California has an ST_UID = 5).
The problem is when a state is selected, I only want the Counties for that state to appear in the County box, i.e, COUNTY.ST_UID = 5 if California is the selected state.
I then tried to convert the value in the st_uid label to an integer:
CODE:
This is what I last tried when again using the Table Adapter Configuration Wizard for the table that populates the County box: SELECT ST_UID, CNTY_NAME FROM COUNTY Where ST_UID = 'StUID' Order By st_uid, cnty_name
What I'm getting is a "Data type mismatch in criteria expression." I'm sure my error is something so simple.

In the below code, I create a DataTable and filter it. When I use filter1, everything works as expected.When I use filter2, everything works as expected only if the SubsectionAmount variable is less than 10. As soon as I set SubsectionAmount=10, the dr2 array returns Nothing.I can't find what is wrong. Here is the code:
Imports System.Data
Partial Class FilterTest
Inherits System.Web.UI.Page[code]..

[code]When I call da.fill I am inserting all records from my query. I was then hoping to filter them to display only those where the GroupingID is equal to 0. When I run the above code. I am presented with all the data, the filter did not work. Please can you tell me how to get this working correctly.

I am writing part of a function that tries to search for a username in a list in a rather broad way (last resort). It seems that LIKE does not like trying to match only the first and last characters.
strCriteria = "somename"
drFilter = tblUsers.Select("User LIKE '" & Strings.Left(strCriteria, 1) & "%" & Strings.Right(strCriteria, 1) & "'")

What i am doing is to enable a user to specify in a combobox on a form a threshold (integer). On a button click the code steps through a datatable until the cumilative value of a field in the records row are equal or dont exceed the figure specified. It then selects these rows and presents them in a datgridview in another form. This all works just fine.
What i am struggling with is undertaking a sort on another field before it starts the filter part. It appears to revert to the default order. Here is my
If ComboBox1.Text = "Co2 saving in tonnes" Then
Dim table As New DataTable
Dim limit As Integer = ComboBox2.Text ' Your threshold

I have a datatable loaded from a database. I bind the datatable to a gridview on page_load. Now I want to filter the gridview by a user selection so I made a checkboxlist and wrote some code as follow at CheckBoxList1_SelectedIndexChanged
[Code]...
With this code above, it can filter if there is only one selection on the checkboxlist. I try to loop the checkboxlist myself but always ended up in errors. Hope someone can help me out to make this work.

Code is:
Private Sub PatientFields()
txtFirstName.Text = pa.Tables(0).Rows(intcurrentindex).Item("Forename").ToString()
txtLastName.Text = pa.Tables(0).Rows(intcurrentindex).Item("Surname").ToString()
[Code]....
Once the search is executed I want to be able to click "refresh" and the original table is then shown in the datagridview. If I try adding after the search sub is completed:
table.DefaultView.RowFilter = Nothing

I 'd like to enable the user to apply a custom filter to a System.Data.DataTable.At the moment I have a very simple function like this:
Dim result = dataTable.Select(txtUserInput.Text)
With the filtered results I'd like to do further operations(e.g. Database Update/Delete).Is an sql injection protection needed or is the "Select" function secure?
//Edit:Can the "select" function be abused to manipulate any data in the datatable, execute code, ...? If the only danger is that this function can return to much/to less data there is no problem. But if the data in the dataset gets corrupted it's a real problem.

I got my regular fields like firstname,lastname, gender, birthyear, street, city, zip, phone. Which i can search through by just entering one of these fields.
Then i got a dropdown box which i was hoping to use a filter on. Every file is in a cabinet, but since those are somewhat alphabetically i have more then 1 cabinet for certain letters. This is why i wanted to use a filter to get a list of all people in a certain cabinet.
So i want my dropdownbox to automatically show the cabinets that are in the database(for example A...Z). If i choose B from the dropdownbox i want to see all the names that are in that cabinet in my datagridview.

I have 2 comboboxes, textbox and a cmdbutton. When the user makes a selection in one combobox I want it to filter the choices in the second combobox. Then when the user clicks the button it passes the values from the comboboxes to a stored procedure and populates a datagridview. I am using VB.net 2005 and sql server 2005.

I am making a combobox dropdown to filter a report. I am using the table adapter to query the data and fill the report from the selected item in the combobox. However, if the user select index 0 (which is "-Select User-") , then the query should disable the filter and select all users in the database. How would I go about doing this with these 2 conditions?

who can clearify more about how to link the relationship between a Local database to ComboBoxes as an example below:
1. ComboType: it will show only kind of audio file extension
2.ComboCompany: will show only the music company name we added
3.ComboVolt: will show of album volt
How it work
If we've selected the ComboType Ex: mp3 file then in the ComboCompany After we have selected with any album name.
The last result is in ComboVolt the number of volt will show up base on we have selected the name of any company name in ComboCompany.
