Hi Experts,

I'm developing a LightSwitch application.
I have and add/edit screen where I would like to disable a drop down list(combo box) if it is in edit mode.

I know how to disable a control. But just don't know how to do it only in edit mode .

 screen.findContentItem("mycombo").isEnabled = false;

Hi, to know if your screen is used to edit/add a new entity. You can check the EntityState on the Property used in the screen.

The code would look something like:

screen.findContentItem("mycombo").isEnabled =  NameOfYourEntityProperty.Details.EntityState != EntityState.Added;

Open in new window

Where "NameOfYourEntity" would be the name of the entity you used to generate the screen.

Below solved the issue. Thanks for your help!

myapp.AddEditLoanMaster.created = function (screen) {
    // Write code here.

   
    if (screen.myscreen.details.entityState != msls.EntityState.added) {
        screen.details.displayName = "Details Edit ";
        screen.findContentItem("mycontrol").isEnabled = false;
    }
 
};
