DoubleUpDown
The DoubleUpDown control provides a TextBox with button spinners that allow incrementing and decrementing Nullable values by using the spinner buttons, keyboard up/down arrows, or mouse wheel.
When using the DoubleUpDown in data binding scenarios, bind your object's value to the Value property. You can specify how much to increment the value by setting the Increment property. You can control the minimum and maximum allowed values by setting the Minimum and the Maximum properties. Use IsReadOnly to determine whether the control is read only. If you would like to get the actual formatted string representation of the value, you can use the Text property.
Default:
<xctk:DoubleUpDown Value="1564.6749586" />
Floating Point:
<xctk:DoubleUpDown FormatString="F3" Value="1564.6749586" Increment=".001" Maximum="200000.599" />
Currency:
<xctk:DoubleUpDown FormatString="C2" Value="1564.6749586" Increment=".5" Maximum="5000.50" Minimum="50.01" />
| Format Specifier | Name |
|---|---|
| C | Currency |
| F | Fixed Point |
| G | General |
| N | Number |
| P | Percent |
You can provide a Watermark to show text in place of a NULL Value.
<xctk:DoubleUpDown Watermark="Enter Double" />
