DateTimeUpDown

The DateTimeUpDown control allows a user to increment or decrement a DateTime using button spinners, up/down keys, or the mouse wheel.

Usage

To use the DateTimeUpDown control simply create an instance of the control in your XAML file, specify the DateTimeUpDown.Value property, and select a Format by setting the DateTimeUpDown.Format property.

<xctk:DateTimeUpDown Value="{Binding LastUpdated}" Format="FullDateTime" />

Modifying the DateTime Value

To increment or decrement the DateTime value, simply select the DateTime part you wish to modify and then interact with either the mouse wheel, spinner buttons, or updown arrow keys. The following image shows what the different DateTime parts look like when you select them.

Depending on your DateTimeUpDown.Format, you may or maynot have all DateTime parts available. You can also get the formatted DateTimeUpDown.Value by using the DateTimeUpDown.Text property.

Formats

Custom Format

If the available formats don't fit you rneeds you can create your own custom format. Simply specfiy the Format property as Custom and then provide a FormatString.

<extToolkit:DateTimeUpDown Format="Custom" FormatString="hh:mm tt" Value="13:30" />
