Question

I’ve created a form that contains a datagridview and I’ve attached a datasource, works well if I want to see every record but I only want it to show a certain persons view, I found some code that people claim works but when I run the program I get an syntax error…

Syntax error: Missing operand after ‘number’ operator.

SO has helped me a lot in the past since I’m new to programming, and if I may ask can you guys help me one again?

Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) _ 
                                  Handles TextBox1.TextChanged
    If TextBox1.TextLength > 0 Then
        frmReportMenu.ProjectBindingSource.Filter = _ 
                String.Format("Register number Like '%" & TextBox1.Text) & "%'"
    Else
        frmReportMenu.ProjectBindingSource.Filter = String.Empty
    End If
End Sub

I’ve created a button when the user clicks on the button a form appears with a textbox

I assume the column name is what is giving you the error. As per my comment,

It shouldn’t contain a space between Register and Number. If it has a space then you have to wrapt the column name like this: [Register number]

Try this please:
String.Format("[Register number] Like '%" & TextBox1.Text) & "%'"
