InputFormats

Gets or sets the array of input formats to be used for parsing date values in the SfDateRangePicker<TValue> component.

Declaration
public string[] InputFormats { get; set; }
Property Value
Type Description
System.String[]

An array of strings representing the acceptable input formats for date values. The default value is null.
Remarks

This property allows the SfDateRangePicker<TValue> to interpret typed date values using a specified array of formats.
The formats can include both standard and custom formats supported in C#. When both InputFormats and Format properties are specified, the InputFormats property takes priority. If only InputFormats is specified, parsing will be attempted using the formats provided in the array.
If neither property is specified, the default behavior remains unchanged.
The parsing logic prioritizes the formats in the order they are specified in the InputFormats array.
If a successful parsing occurs, the SfDateRangePicker<TValue> updates its value accordingly. Error handling is controlled by the StrictMode property, allowing for different user experiences in case of invalid input.
