asp.net 設置GridView的選中行

<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>
然後在gridview的rowDataBound中, 添加處理按鍵的事件處理函數和使用鼠標點擊某行時的選中事件.
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++;
}
}
當點某行時,直接選中,然後移動方向鍵則切換不同的選中行; 如果直接按方向鍵,則從第一行開始標識
