Data dialog

This dialog allows you to configure the data source for a Grid object.

Grid Data – Text File

When the Data Source type is set to Text File, you can configure the following settings:

• File: Enter the name of the text file source. You can either type the file name and its path or click the … button to browse for it. (If the file is stored in your project folder, you can omit the path in the name.) This field accepts String expressions.

• Delimiters: Set the delimiter(s) used in the data source file. For instance, if the data will be read from a CSV (comma separated values) file, you would select the Comma option. You can even choose a custom delimiter by checking the Other option and typing the custom delimiter in the field beside it.

• Read only checkbox: When this option is checked, the Grid object will only read data from the specified file. The object will not write anything to the file.

Grid Data – Class Tag

When the Data Source type is set to Class Tag, you can configure the following interface:

• Class Tag: Enter the name of the main class tag source. (Do not specify a specific member of the class tag.) You can specify the initial array position in this field (for example, Mytag[10]); otherwise, 0 (zero) will be used as the initial position by default.

• Number of Items: Enter the number of array positions from the Class Tag that should be displayed.

• View: When the tag configured in the optional field changes value (for example, toggles) during runtime, the grid object launches a dialog, allowing the user to show/hide each column or modify their positions.

  

Grid Data – Database Configuration

When the Data Source type is set to Database, you can configure the following settings:

Please refer to the Database Configuration dialog for further information about this dialog.

Note: Configuring a secondary (redundant) database for a Grid object will make the content of the object read-only — that is, the object can read and display data from the primary or secondary database, as needed, but changes made in the object cannot be written to either database. This also means that the options Insert Trigger and Save on data change will have no effect. For more information about those options, see Advanced dialog.
