In this blog we will see how to enable / disable contract
class parameter control based on the modification of other contract class
parameter. This all is going to be happened in UI Builder class
So here we go
1.
First write the Method which is responsible to
perform actual functions like enabling and disabling control
In this blog I will be using Enum Control and
based on its modification disabling lookup controls
Where in below image Report Type is Enum
Control and WindMast and Sensor are the lookup controls
Enable/ Disable Method should be written in
UI Builder class will be like
private boolean
EnableControls(FormComboBoxControl _control)
{
if(_control.valueStr() == enum2str(TK_TurbineSummary::Production))
{
dWindMast.enabled(false);
dSensor.enabled(false);
}
else
{
dWindMast.enabled(true);
dSensor.enabled(true);
}
return true;
}
In above piece of code I
have disable the lookup controls On “Production” Report Type and make them enable
on Wind Speed Report Type
Where dWindMast and dSensors are the dialog field
define in Build method of UI Class like Below
Now In Post Build Method of UI Class we need
to register our above created method “EnableControls” Like below
public void postBuild()
{
dReportType =
this.bindInfo().getDialogField(this.dataContractObject(),
methodStr(TK_TurbineSummaryContract, parmReportType));
dReportType.registerOverrideMethod(methodStr(FormComboBoxControl,
modified), methodStr(TK_TurbineSummaryUI, EnableControls), this);
dShowProduction = this.bindInfo().getDialogField(this.dataContractObject(),
methodStr(TK_TurbineSummaryContract, parmShowProduction));
}
When we Run Report and change the Report
type Drop down value Result will be as below
Disable Controls :
Enabling Control on drop down selection changed
