The Sheridan combo box has two properties that can be bound to RDS.DataControl data. Just binding the combo box to RDS.DataControl doesn't automatically populate the "Text" portion, a nonbindable property that shows the currently selected item. As a result, old data may still be displayed after the Refresh method is called.
A workaround is to use code like either of the following two sample Microsoft® Visual Basic®, Scripting Edition Sub procedures. Both clear the Text property when the Refresh method is called. SSCombo is the name of the Sheridan combo box control in these examples.
Sub SSCombo_InitColumnProps()
SSCombo.Text=""
End Sub
Sub Refresh_OnClick
ADC1.Refresh
SSCombo.Text=""
End Sub
