DataGridView Row Filter not applying

Question

I have a DataGridView1 and I'm trying to filter it using a Row Filter. I also have a string: SomethingHere

I have a FilterString that I'm using as a string in the following format:

 Dim DGVDV As New DataView
 Using iConn As New OleDbConnection(ConnString)
      Using iDA As New OleDbDataAdapter(iSelectString, Conn)
           iDA.MissingSchemaAction = MissingSchemaAction.AddWithKey
           iDA.FillSchema(DS.Tables("Table"), SchemaType.Source)
           iDA.Fill(DS.Tables("Table"))
           iBS.DataSource = DS.Tables("Table")
           DGVDV = DS.Tables("Table").DefaultView

           With DataGridView1
                .DataSource = iBS
           End With
      End Using
 End Using





 DGVDV = DS.Tables("Table").DefaultView
 DGVDV.RowFilter = FilterString

To prove that it's working, I have right below it:

 Msgbox("Filter: " & DGVDV.RowFilter.ToString)

This messagebox only fires when the FilterString is in this format:

 FilterString = "[Status] = '" & SomethingHere & "'"

However, the Row Filter seems to be ignoring a string like the two below:

 FilterString = "([Status] = '" & CMBFilter & "')" & " AND ([ID] LIKE '%" & SomethingHere & "%' OR [Name] LIKE '%" & SomethingHere & "%')"

 FilterString = "([ID] LIKE '%" & TextFilter & "%' OR [Name] LIKE '%" & TextFilter & "%')"

I've tried Googling, and I just can't figure out what the issue is.

    If CMBBool = True And TextBool = False Then
        FilterString = "[Status] = '" & CMBFilter & "'"
    ElseIf CMBBool = False And TextBool = True Then 
        FilterString = "([ID] LIKE '%" & TextFilter & "%' OR [Name] LIKE '%" & TextFilter & "%')"
        MsgBox(FilterString)
    ElseIf CMBBool = True And TextBool = True Then
        FilterString = "([Status] = '" & CMBFilter & "')" & " AND ([ID] LIKE '%" & TextFilter & "%' OR [Name] LIKE '%" & TextFilter & "%')"
        MsgBox(FilterString)
    ElseIf CMBBool = False And TextBool = False Then
        FilterString = String.Empty
    End If
    DGVDV.RowFilter = FilterString
    MsgBox("Filter: " & DGVDV.RowFilter.ToString)

When the FilterString is as below

 FilterString = "[Status] = '" & CMBFilter & "'"

The Msgbox pops up. For the other FilterStrings, no Msgbox pops up, making me suspect that the FilterString is never being applied to the row filter.

Can anyone help?

使用这种格式可以：

DataView.RowFilter = string.Concat("CONVERT(", COLUMNNAME,",System.String) LIKE '%", TEXTBOXorSTRING, "%'")
