Editing Options
Here can you set options about editing.

Default Value Here can you set the default value for the cell when adding a row. The default value control differs between the control types.
For a Textbox control you have a textbox to fill in the default value

For a Numeric control you have a Spin button to choose your value:

For a Checkbox control you have a switch you can set the default value with:

For a Date control you have a date picker:

You can also set the current date automatically by enable Set current date.
Is Required If you want a column to be mandatory, even if the column is nullable in the database, you can switch on the Is Required . If the column is left blank, the row will not be saved and an error will occur.
Allow Editing If this switch is off, the user can't edit the column. You can also use the "Pen"-icon in the field list on the left. If set to false, the field will be read-only and background color will become grey.
