12.Panel 横向滚动，纵向自动扩展
<asp:panel style="overflow-x:scroll;overflow-y:auto;"></asp:panel>
13.回车转换成Tab
<script language="javascript" for="document" event="onkeydown">
if(event.keyCode==13 && event.srcElement.type!='button' &&
event.srcElement.type!='submit' && event.srcElement.type!='reset'
&& event.srcElement.type!=''&& event.srcElement.type!='textarea');
event.keyCode=9;
</script>
onkeydown="if(event.keyCode==13) event.keyCode=9"

14.DataGrid超级连接列
DataNavigateUrlField="字段名" DataNavigateUrlformatString="http://xx/inc/delete.aspx?ID={0}"
15.DataGrid行随鼠标变色
private void DGzf_ItemDataBound
(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if (e.Item.ItemType!=ListItemType.Header)
{
e.Item.Attributes.Add( "onmouseout","this.style.backgroundColor=
\"" e.Item.style["BACKGROUND-COLOR"] "\"");
e.Item.Attributes.Add( "onmouseover","this.style.backgroundColor=\"" "#EFF3F7" "\"");
}
}
16.模板列
<ASP:TEMPLATECOLUMN visible="False" sortexpression="demo" headertext="ID">
<ITEMTEMPLATE>
<ASP:LABEL text='<%# DataBinder.Eval(Container.DataItem,
"ArticleID")%>' runat="server" width="80%" id="lblColumn" />
</ITEMTEMPLATE>
</ASP:TEMPLATECOLUMN>
