Database Search Solution

Im currently trying to implement a search function into my program, form is as shown in attachment. I am using a data environment with a command that has a relationship to my car table and an sql statement as shown below

SELECT * FROM Car WHERE car_registration_plate LIKE '" & TxtSearch.Text & "*'

I then have the code below for the command button oviously nothing shows in the datagrid to begin with but when text is entered and the search button clicked it should show the record from the text that is entered, when i change the txtsearch bit in the code above to a record in my table it shows that record in the datagrid upon form load up, so i dont know why it doesnt show it when the text is entered

Search command button

Private Sub cmdsearch_Click()
Dim strSearch As String
Dim SQLString As String

DataGrid1.Refresh

End Sub

Can anyone help, iv been trying to solve it for hours

VB Code:

Private Sub cmdsearch_Click()
Dim strSearch As String
Dim SQLString As String
[B]Set DataGrid1.Recordset= DataEnvironment1.....[/B]
End Sub

New Code

Private Sub cmdsearch_Click()

Dim StrSearch As String
Dim SQLString As String

TxtSearch = StrSearch
Set DataGrid1.Recordset = DataEnvironment1.CarSearch

DataGrid1.Refresh

End Sub

When Run i get an error saying:
Complile Error:
Method or data member not found

Tried changing the code to:
Set DataGrid1.DataSource = DataEnvironment1.CarSearch

But still no joy, what else could it be?
