ASP.NET程序中常用的三十三种代码(3)
ASP.NET程序中常用的三十三种代码(3) 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>
<ASP:TEMPLATECOLUMN headertext='选中'>
<HEADERSTYLE wrap='False' horizontalalign='Center'></HEADERSTYLE>
<ITEMTEMPLATE>
<ASP:CHECKBOX id='chkExport' runat='server' />
</ITEMTEMPLATE>
<EDITITEMTEMPLATE>
<ASP:CHECKBOX id='chkExportON' runat='server' enabled='true' />
</EDITITEMTEMPLATE>
</ASP:TEMPLATECOLUMN>
后台代码
protected void CheckAll_CheckedChanged(object sender, System.EventArgs e)
{
//改变列的选定,实现全选或全不选。
CheckBox chkExport ;
if( CheckAll.Checked)
{
foreach(DataGridItem oDataGridItem in MyDataGrid.Items)
{
chkExport = (CheckBox)oDataGridItem.FindControl('chkExport');
chkExport.Checked = true;
}
}
else
{
foreach(DataGridItem oDataGridItem in MyDataGrid.Items)
{
chkExport = (CheckBox)oDataGridItem.FindControl('chkExport');
chkExport.Checked = false;
}
}
}
17.数字格式化
【<%#Container.DataItem('price')%>的结果是500.0000,怎样格式化为500.00?】
<%#Container.DataItem('price','{0:¥#,##0.00}')%>
int i=123456;
string s=i.ToString('###,###.00');
