Default LiveBindings Methods

Go Up to Using Custom Format and Parse Expressions in LiveBindings

RAD Studio provides the following methods that you can use in LiveBindings format and parse expressions:

Method	Description
`CheckedState(check box)`	Evaluates a VCL check box and returns a string with one of the following values: `'True'` if the `State` of the check box is `cbChecked`. `'False'` if the `State` of the check box is `cbUnchecked`. `''` if the `State` of the check box is `cbGrayed`.
`DBUtils_ActiveRecord(dataset)`	Evaluates a dataset and returns the index of the current record.
`DBUtils_BoolValue(value)`	Returns the specified value as a boolean.
`DBUtils_ValidRecNo(dataset, index)`	Returns: The specified index if it exists in the specified dataset. An existing index of the dataset if the specified index does not exist in the dataset. `-1` if the first parameter is not a dataset or if the dataset has no records.
`Format(format string, argument 1, argument 2, …)`	Works as System.SysUtils.Format, except that instead of expecting an array as the second parameter, it takes any argument as an extra parameter. For example, if in Delphi you have `Format('%d %d', [1, 2])`, here it would be `Format("%d %d", 1, 2)`.
`FormatDateTime(format string, date)`	Works as System.SysUtils.FormatDateTime.
`IfAll(argument 1, argument 2, …)`	Returns `True` only if all its arguments evaluate to `True`. Otherwise, it returns `False`.
`IfAny(argument 1, argument 2, …)`	Returns `True` if at least one of its arguments evaluates to `True`. If all its arguments evaluate to `False`, it returns `False`.
`IfThen(condition, value if true, value if false)`	Returns `value if true` if `condition` evaluates to `True`; otherwise, it returns `value if false`.
`Lookup(scope lookup, key fields, key values, result fields)`	Works as Data.Bind.Components.IScopeLookup.Lookup, where `scope lookup` is an object that implements IScopeLookup and the remaining arguments are the parameters of IScopeLookup.Lookup.
`LowerCase(string)`	Works as System.UnicodeString.LowerCase.
`Math_Max(value 1, value 2)`	Works as System.Math.Max.
`Math_Min(value 1, value 2)`	Works as System.Math.Min.
`Round(value)`	Works as System.Round.
`SelectedDateTime(editor)`	Works as Data.Bind.Components.IBindDateTimeEditEditor.SelectedDateTime.
`SelectedItem(editor)`	Works as Data.Bind.Components.IBindListEditorCommon.GetSelectedItem.
`SelectedLookupValue(editor)`	Works as Data.Bind.Components.IBindListLookupEditor.GetSelectedLookupValue.
`SelectedText(editor)`	Works as Data.Bind.Components.IBindListEditorCommon.GetSelectedText.
`SelectedValue(editor)`	Works as Data.Bind.Components.IBindListEditorCommon.GetSelectedValue.
`StrToDateTime(string)`	Works as System.SysUtils.StrToDateTime.
`SubString(string, index, count)`	Works as System.UnicodeString.SubString.
`SynchIndex(editor)`	Works as Data.Bind.Components.IBindListSynchEditor.GetSynchIndex.
`ToNotifyEvent(value)`	Converts `value` into an event.
`ToStr(value)`	Converts `value` into a string.
`ToVariant(value)`	Converts `value` into a variant.
`UpperCase(string)`	Works as System.UnicodeString.UpperCase.
