Flex selectComboBox(), mkII
At the suggestion of a coworker, I've made a tiny change to my selectComboBox() function. The purpose of this function is to automatically select something in a ComboBox, such as if you're editing a form. But what if the function ends up doing nothing because no matches were found? Now it'll return false in that case. Also I properly capitalized it.
private function selectComboBox(cb:ComboBox, column:String, value:String):Boolean{
if( value == null )
return;
for( var i:int=0; i<cb.dataProvider.length; i++ ){
if( value == String(cb.dataProvider[i][column]) ){
cb.selectedIndex = i;
return true;
}
}
return false;
}
if( value == null )
return;
for( var i:int=0; i<cb.dataProvider.length; i++ ){
if( value == String(cb.dataProvider[i][column]) ){
cb.selectedIndex = i;
return true;
}
}
return false;
}
Usage:
selectComboBox(cbType,"type",DiscFormData.Type);
It will search the dataprovider of cbType, looking at the "type" field, and select the item if it matches the third value passed in. Now to use the returned value...
isMatched = selectComboBox(cbType,"type",DiscFormData.Type);
if( !isMatched ){
/*do some code... add this value to the dataprovider? error message?*/
}
if( !isMatched ){
/*do some code... add this value to the dataprovider? error message?*/
}
Or hey, get real fancy...
if( !selectComboBox(cbType,"type",DiscFormData.Type) ){
/*do some code... add this value to the dataprovider? error message?*/
}
/*do some code... add this value to the dataprovider? error message?*/
}
