try this one. but you need to handle text, if user delete the text then may
chance the text appears numeric or underscore at zero index.
[*Bindable*]
*private* *var* pos:Number=0;
*protected* *function* txt_changeHandler(event:TextOperationEvent):*void*
{
*//validateTextInput(txt.text.length);*
}
*protected* *function* txt_selectionChangeHandler(event:FlexEvent):*void*
{
pos=TextInput(event.target).selectionAnchorPosition;
validateTextInput(pos);
}
*private* *function* validateTextInput(cursorPos:int=-1):*void*
{
*if* (cursorPos > 0)
{
txt.restrict=*"a-zA-Z0-9_"*
}
*else*
{
txt.restrict=*"a-zA-Z"*
}
*trace*(*"Current Position --- "* + cursorPos);
}
<s:Label text="{*'lastCursorPos '* + pos}"/>
<s:TextInput id="txt"
restrict="a-zA-Z"
change="txt_changeHandler(event)"
selectionChange="txt_selectionChangeHandler(event)"/>
