Field advanced settings

Visible condition

May be used to enter a macro condition that must be fulfilled in order for the specific parameter to be visible in the report's filter.

You can write any condition according to your specific requirements. For details about available macro options and syntax, please refer to the Development -> Macro expressions chapter of the Developer's Guide.

If you wish to create a condition that depends on the state of the other parameters in the filter, you can access them in the macro expression using the corresponding Column name. The data of the given fields may then be retrieved through the following properties:

•Value - returns the current value of the parameter. For example, FromDate.Value is resolved into the value entered into the report's FromDate parameter.

•Visible - returns a true value if the given parameter is currently visible in the filter.

•Enabled - true if the parameter is currently enabled, i.e. its value can be edited.

•Info.<field setting> - may be used to access various settings configured for the parameter's field, for example: FromDate.Info.DefaultValue

Enabled condition

Allows you to enter a macro condition that determines when the parameter should be enabled. If this condition is resolved as false, the parameter will be visible, but it will not be possible to edit its value.

You can use the same macro options as described above for the Visible condition property.

Has depending fields

If enabled, the report filter will be refreshed via autopostback whenever the value of the given parameter is changed. This means that other parameters can be dynamically updated according to the current value of the parameter.

Please note that the actual logic of the dependencies needs to be implemented in the code of the used form controls.

Depends on another field

This option must be enabled if you wish to have the behavior of the parameter dynamically changed according to the value of some other parameter.

Category

Category name

Sets the name of the category that is displayed in the report's filter.

Collapsed by default

If enabled, the category will initially be collapsed when the filter is loaded.

Visible

Indicates if the category and all of the parameters under it should be visible in the filter.

Visible condition

May be used to enter a macro condition that must be fulfilled in order for the category to be visible. You can use the same macro options as described above for the Visible condition property of parameters.
