问题 I think my question title is quite straight forward. Any help is appreciated.. 回答1: With BoundField and in readonly mode you can use GridView1.Rows[x].Cells[x].Text but with edit mode you have to use Controls collection to get reference of a control.

Is there any way to avoid the auto adjust behavior for that type of grid? I'm aware that the piece of code below

First please look at my getView code: @Override public View getView(int position, View convertView,
