Hi,
I want to let the "to" date be after the "from" date, and I have two databox as following, so can anyone tell me how to constrain the "to" date be after the "from" date?
<vbox align="end">
<hbox>
<label value="From: " />
<datebox id="from" format="yyyy-MM-dd HH:mm:ss" width="120px" readonly="true" constraint="between 20100401 and 20101231" />
</hbox>
<hbox>
<label value="To: " />
<datebox id="to" format="yyyy-MM-dd HH:mm:ss" width="120px" readonly="true" constraint="between 20100401 and 20101231" />
</hbox>
</vbox>
thanks a lot. ^_^
Hi yuanbohan
the following example works fine for me.
<zscript><![CDATA[
import java.text.SimpleDateFormat;
void fromChanged(){
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
to.setConstraint("between " + sdf.format(from.getValue()) + " and 20101231" );
}
]]>
</zscript>
<vbox align="end">
<label value="From: " />
<datebox id="from" format="yyyy-MM-dd HH:mm:ss" width="120px" readonly="true" constraint="between 20100401 and 20101231" onChange="fromChanged()/>
</hbox>
<hbox>
<label value="To: " />
datebox id="to" format="yyyy-MM-dd HH:mm:ss" width="120px" readonly="true" constraint="between 20100401 and 20101231" />
</hbox>
</vbox>
