Using Conditional Formatting
Now we will hide the buttons the that users do not need to see when they are entering data.
We will can hide the Delete and Update buttons when the details on the screen are blank. To do this, we can test the value of UID. Remember that the UID field is configured on the edit screen , and is hidden - — but this means we can use the value of UID. We know that UID is always set for every record, so we can test whether this is null or not to work out whether the fields on the edit form are currently populated. Remember that to access a value on the edit form in an expression we can use _form.
- To conditionally hide the
Deletebutton:- Click on the
Deletebutton to open the configuration form. - Go to the section Formatting Rules.

_form.UID== _NULL - Since there is currently no hidden style, we will add one:.
