asp.net 设置GridView的选中行


            <script type="text/javascript"> var currentRowId = 0; function SelectRow() { if (event.keyCode == 40) MarkRow(currentRowId+1); else if (event.keyCode == 38) MarkRow(currentRowId-1); } function MarkRow(rowId) { if (document.getElementById(rowId) == null) return; if (document.getElementById(currentRowId) != null ) document.getElementById(currentRowId).style.backgroundColor = '#ffffff'; currentRowId = rowId; document.getElementById(rowId).style.backgroundColor = '#ff0000'; } </script> 然后在gridview的rowDataBound中, 添加处理按键的事件处理函数和使用鼠标点击某行时的选中事件. protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes.Add("id", _i.ToString()); e.Row.Attributes.Add("onKeyDown", "SelectRow();"); e.Row.Attributes.Add("onClick", "MarkRow(" + _i.ToString() + ");"); _i++; } } 当点某行时,直接选中,然后移动方向键则切换不同的选中行; 如果直接按方向键,则从第一行开始标识
