THISFORM.oSetAllX.SetAllX(THIS, "ClearSearchString", "", "Textbox")

>
>I am using the following SetAllx call in the Grid.Valid() for each textbox(es) in the columns:
>

THISFORM.oSetAllX.SetAllX(THIS, "ClearSearchString()", "", "Textbox")

>
>As not all textboxes involved in the columns of the grid have this method I get the following error for such textboxes
>

Property CLEARSEARCHSTRING not found

>
>Please advise on how to modify the SetAllx call so that I can avoid the error message
