Hi Kate!\
Drag and drop Mask **Textbox** from the toolbox and set the **Mask Property** as per your requirement. E.g. if you want to set number as input format then set the 00000 (length as your required) mask property.\
You can get the help from the following link\

I hope it resolve your problem.
