After creating your view are you using it in 0 ? If columns are different also set columncount = -1 before assigning recordsource.

OTOH if that's readonly why are you using views ? You could just use SQL as recordsource :
RecordSourceType = 4
RecordSource = "select * from mytable where lSomeExpression"

To change :
RecordSource = ""
RecordSource = "select * from mytable where lNewExpression"

Even the expression could be parametric so you don't need to change "recordsource" too. Just supply parameter and refresh the grid.

RecordSource = "select * from mytable where SomeField = thisform.SomeProperty"

thisform.Someproperty = "New Value"
thisform.myGrid.refresh

But if you use this approach be sure you have an index on field(s) used in where clause.
