Error when selecting using LINQ and looping results

I have written the following code:

Dim selectedFrame = (From SF In TOCFrames Where SF!Model = cboModel.Text Select SF!Model, SF!Colour, SF!PROS_Design, SF!PROS_Description)
For Each Item In selectedFrame
    If Not IsDBNull(Item.Colour) Then
        txtColour.Text = Item.Colour
    Else
        txtColour.Text = ""
    End If

    If Not IsDBNull(Item.PROS_Design) Then
        txtDesign.Text = Item.PROS_Design
    Else
        txtDesign.Text = ""
    End If

    If Not IsDBNull(Item.PROS_Description) Then
        txtDescription.Text = Item.PROS_Description
    Else
        txtDescription.Text = ""
    End If
Next

Which normally works however is not working at the moment. I have an error message that says:

Error 55 'Item' is not declared. It may be inaccessible due to its protection level.

I have tried to search the internet for a solution, however have been unsuccessful with this. If anyone would help me out then that would be great!

is Option Strict ON?
For Each Item As <objecttype> In selectedFrame

Which line is is indicated as having the error.

If I had to guess, it would be the LINQ statement.

You are using an antiquated syntax in that statement to index the default property of "SF".

SF!Model could be the same as SF.Item("Model"); typically, the default property is named "Item".

Solution 2

The problem was that I had option explicit on and also was not looping Item as object.

Thank you all for your help!
