Hi @Tejaswini1234 


If you want to reset the textInput control when a different dropdown item is selected you can use the below expression:
Dropdown Control -> OnChange -> Reset(DataCardValue23)
Here, DataCardValue23 refers to the name of text input control inside the edit form. This will reset the control to its default value.
In case you are editing existing item in your sharepoint list, this will default to Parent.Default value. To update this scenario, you can use below expressions:
Dropdown Control -> OnChange -> Set(TextBoxValue,Blank())
TextInput -> Default -> If(IsBlank(TextBoxValue),Blank(),Parent.Default)
Here, this will clear the text box.


Hope this Helps!
