Asp.Net清空页面所有textbox的几种方法总结
在Asp.Net中清空所有textbox有好几种方法，本文提供几种，供大家参考！
foreach( Control childControl in this.Controls )
{
if( childControl is TextBox )
((TextBox)childControl).Text = "";
}
}
foreach( Control childControl in this.Controls )
{
if( childControl is TextBox )
((TextBox)childControl).Text = "";
}
}
用反射:
FieldInfo[] infos = GetType().GetFields( BindingFlags.Public | BindingFlags.NonPublic|BindingFlags.GetField |BindingFlags.Instance);
for(int i=0;i<infos.Length;i++)
{
if(infos[i].FieldType == typeof(TextBox))
{
((TextBox)infos[i].GetValue(this)).Text = "";
}
}
//使用javascript,好处是不用刷新页面：
function ClearAllTextBox()
{
var obj=window.document.forms[0];
for(i=0;i<obj.elements.length; i++)
{
var elem=obj.elements[i];
if(elem)
{
if(elem.type=="text")
{
elem.value="";
}
}
}
}
//最后一种用Jquery
function ClearText() {
$("input").each(function() {
$(this).val('');
});
}
1.连接数据库文件
<add name="LocalSqlServer" connectionString="Data Source=.\SQLExpress;Integrated Security=True;AttachDBFilename=|DataDirectory|TimeTracker.mdf;User Instance=true" />
SqlConnectionStringBuilder实例化时，要用到connectionString，如：SqlConnectionStringBuild builder = new SqlCon ......
