API
Parameters
| Parameter | Default | Type |
|---|---|---|
AriaLabel | Resize | string |
Describes the separator's purpose to assistive technologies. Uses a localized default when omitted. When omitted, uses the localized "Resize" label. | ||
Disabled | false | bool |
Prevents both pointer and keyboard resizing when enabled. | ||
KeyboardStep | 10 | double |
Determines how many pixels each applicable arrow-key press adds or removes. | ||
Max | null | double? |
Limits the target, or logical start target, in pixels; a null value leaves the upper bound unrestricted. | ||
Min | 0 | double |
Prevents the target, or logical start target, from falling below this pixel value. | ||
Offset | 0 | double |
Moves the resizer outward from its configured edge by the specified number of pixels. Negative values move it inward. | ||
Orientation | Horizontal | Orientation |
Controls the resize axis. Vertical resizers change width, while horizontal resizers change height. Possible values: HorizontalVertical | ||
Placement | End / Bottom | Placement? |
Positions the resizer on the target edge. In coordinated mode, target order determines the resize direction. When omitted, uses End for vertical separators or Bottom for horizontal separators. | ||
ResizeProperty | width / height | string |
Names the CSS property updated during single-target resizing. Coordinated targets define their own resize properties. When omitted, uses width for vertical separators and height for horizontal separators. | ||
ResizingInterval | 100 | int |
Throttles Resizing notifications to at least this many milliseconds apart. | ||
ShowGutter | false | bool |
Displays the provider-styled gutter, borders, and grip when enabled. The resize area is transparent by default. | ||
TabIndex | 0 | int |
Controls the resizer's position in the keyboard tab order while it is enabled. | ||
TargetId | — | string |
Identifies the element that receives size updates. Used only when Targets is not supplied. | ||
Targets | null | ResizerTargets |
Enables coordinated resizing of logical start and end targets while preserving their combined size. Both targets must resolve. | ||
Thickness | null | double? |
Overrides the resizer thickness in pixels. Vertical resizers use it as width and horizontal resizers as height. | ||
Value | null | double? |
Supplies the controlled target size in pixels. In coordinated mode, this is the logical start-target size. | ||
Events
| Event | Type |
|---|---|
ResizeEnded | EventCallback<ResizerEventArgs> |
Signals that resizing has finished, including canceled pointer interactions. | |
ResizeStarted | EventCallback<ResizerEventArgs> |
Fires once when pointer or keyboard resizing begins. | |
Resizing | EventCallback<ResizerEventArgs> |
Reports intermediate sizes at the cadence configured by ResizingInterval. | |
ValueChanged | EventCallback<double> |
Occurs when a resize interaction commits a new value. | |
