Custom pcf for 2 same field on form

(0) ShareShare

Posted on by 2
Hello,
I have 2 same optionset fields on the form in my model driven app.. So I created 1 custom pcf control  and tagged to both the same fields.
When I select a value on field 1, field 1's updateview is called, which changes color of the selected option.
But how to call field 2's update view also at that time?
 
I have the same question (0)

    Hi @rashi_malhotra 

     

    Please follow these steps

    In your app's form, make sure both Field 1 and Field 2 are using your custom PCF control as their control type.

    By following these steps, when you select a value on Field 1, the custom PCF control's notifyOutputChanged method will be called. It will then update the view for Field 1 based on the selected value and notify Field 2 about the new value, triggering its update view as well. This way, both fields will stay in sync with each other when you interact with the custom control.

     

    Inside your PCF control code, make sure you have defined two properties to hold the values for Field 1 and Field 2:

    //Sample code

    exportinterfaceMyControlProps

    {

    demofield1: number;

    demofield2: number;

    …..

    }

     

    Implement the notifyOutputChanged method in your control. This method will be called whenever a property value changes.

    publicnotifyOutputChanged(inputs: PropertyBag): void

    { // Check if Field 1 value has changed

    if(inputs.hasOwnProperty("demofield1"))

     {

    const demofield1 = inputs["demofield1"] as number;

    this._notifyField2Updated(demofield1);

     }

    Define the _notifyField2Updated method in your PCF control to trigger the update view for Field 2:

    private_notifyField2Updated(newValue: number): void

    {

    valuethis.notifyOutputChanged({ demofield2: newValue });

    }

    Hi @DeviKrishna, thanks for the approach, means a lot.

    BTW I just realized that my code works properly for the 1st time I update the field, both the fields get updated automatically. But the next time I update the 1st field it updates only that field and not the 2nd one. Any idea why?
