Property Value
Type Description
System.String[]

Remarks

This property allows the SfDatePicker<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 SfDatePicker<TValue> updates its value accordingly. Error handling is controlled by the StrictMode property, allowing for different user experiences in case of invalid input.

Examples

The following example demonstrates how to set the InputFormats property to accept multiple date formats:

Placeholder
