i arguing myself for a bit by choosing the right component to solve my application.

It is a Application for presenting a huge amount of data in a grid, the summary of each Grid Row should be displayed onselect, in a dataview or textare and this is the point where i want to go the right way of choosing the best component, at first i have choosen the dataview but now i think i need the methods of a textare, but i cant add a store to the textare, and this abillity i dont want to miss.

My thougths at this time are:
The methods to handle document.selection and accessing and handling the text are neccesary, for me.

On the oter side, the dataview side, i need to display the summary whith a XTemplate Logic annd the corresponding datastore.

Is there any way to inherit the methods of the Textarea ?
