You can use this code in the form's init method after super():

ComboBoxName.selection(ComboBoxName::DefaultValue);

If this is a table field I'd suggest overriding the initValue method in the table:

this.ComboBoxName = ComboBoxName::DefaultValue;

Override initValue in the form's datasource only if it should be a specific behaviour in this form only.

thanks, i got confused whether to write the code in `init` or `initValue` but your answer clarified my doubts...thnks once again. – piku Apr 27 '11 at 06:35
could you plz explain the reason of using the code after `super()`? – piku Apr 27 '11 at 11:02
And also `this.ComboBoxName = ComboBoxName::DefaultValue;` is not working instead i have to put the datasource name then only it works why? – piku Apr 27 '11 at 11:13

1) If you try using it before `super()` you'll get a "FormComboBoxControl object not initialized" error message. 2) "this.ComboBoxName" should be used in "\Data Dictionary\Tables\TableName\Methods\initValue" – 10p Apr 27 '11 at 15:34
