Hi you can do so by using ZoomToAsync method. You can find the documentation here: https://pro.arcgis.com/en/pro-app/latest/sdk/api-reference/topic12017.html, and a sample code here:

This custom tool did the pan of the map for me:

internal class MousePanTool : MapTool { [DllImport("user32.dll")] public static extern short GetAsyncKeyState(UInt16 virtualKeyCode); public const int VK_LBUTTON = 0x01; private short _lastMouseButtonState = -1; private System.Windows.Point _fromMousePoint = new() { X = double.NaN, Y = double.NaN }; private System.Windows.Point _toMousePoint = new() { X = double.NaN, Y = double.NaN }; public MousePanTool() { SketchOutputMode = SketchOutputMode.Map; } /// <summary> /// Called when the mouse button is clicked in the view. /// </summary> protected override void OnToolMouseDown(MapViewMouseButtonEventArgs e) { if (e.ChangedButton == System.Windows.Input.MouseButton.Left) { _fromMousePoint = e.ClientPoint; e.Handled = true; System.Diagnostics.Trace.WriteLine("!!! OnToolMouseDown"); } base.OnToolMouseDown(e); } /// <summary> /// Called when the mouse button is released in the view. /// </summary> protected override void OnToolMouseUp(MapViewMouseButtonEventArgs e) { if (e.ChangedButton == System.Windows.Input.MouseButton.Left) { e.Handled = true; _fromMousePoint = new() { X = double.NaN, Y = double.NaN }; System.Diagnostics.Trace.WriteLine("!!! OnToolMouseUp"); } base.OnToolMouseUp(e); } private bool _isPanning = false; protected override async void OnToolMouseMove(MapViewMouseEventArgs e) { var mapView = MapView.Active; if (mapView == null || _isPanning) return; var mouseButtonState = GetAsyncKeyState(VK_LBUTTON); if ((mouseButtonState & 0x8000) == 0x0) { // the physical left button is not down anymore - stop panning _fromMousePoint = new() { X = double.NaN, Y = double.NaN }; if (_lastMouseButtonState != mouseButtonState) { System.Diagnostics.Trace.WriteLine("!!! MouseUp during mouse move"); _lastMouseButtonState = mouseButtonState; } return; } _lastMouseButtonState = mouseButtonState; if (_fromMousePoint.X != double.NaN) { _toMousePoint = e.ClientPoint; _isPanning = true; try { await QueuedTask.Run(() => { var fromPoint = mapView.ClientToMap(_fromMousePoint); var toPoint = mapView.ClientToMap(_toMousePoint); var deltaX = toPoint.X - fromPoint.X; var deltaY = toPoint.Y - fromPoint.Y; var camera = mapView.Camera; camera.X -= deltaX; camera.Y -= deltaY; mapView.PanTo(camera); _fromMousePoint = _toMousePoint; }); } catch (Exception ex) { System.Diagnostics.Trace.WriteLine(ex); } finally { _isPanning = false; } _isPanning = false; e.Handled = true; } } protected override Task OnToolActivateAsync(bool active) { _fromMousePoint = new() { X = double.NaN, Y = double.NaN }; return base.OnToolActivateAsync(active); } protected override Task OnToolDeactivateAsync(bool active) { _fromMousePoint = new() { X = double.NaN, Y = double.NaN }; return base.OnToolActivateAsync(active); } }

This sample only works for 'right-handed' mouse configurations, meaning the left mouse button is the 'physical' left mouse button. To consider a 'left-handed' mouse configuration you can determine the system's current mapping of physical mouse buttons to logical mouse buttons by calling GetSystemMetrics(SM_SWAPBUTTON) which returns TRUE if the mouse buttons were swapped.

Instead of writing your own custom navigation you can also reuse the map navigation functionality that's built into ArcGIS Pro:

var command = FrameworkApplication.GetPlugInWrapper("esri_mapping_exploreTool") as ICommand; if (command.CanExecute(null)) command.Execute(null);

In order to consider left-handedness, you can use this code snippet (i didn't test this one):

[DllImport("user32.dll")] public static extern short GetAsyncKeyState(UInt16 virtualKeyCode); public const int VK_LBUTTON = 0x01; public const int VK_RBUTTON = 0x02; private short _lastMouseButtonState = -1; [DllImport("user32.dll")] public static extern Int32 GetSystemMetrics(Int32 bSwap); public const int SM_SWAPBUTTON = 23; ... var logicalLeftButton = Convert.ToUInt16(GetSystemMetrics(SM_SWAPBUTTON) != 0 ? VK_RBUTTON : VK_LBUTTON); var mouseButtonState = GetAsyncKeyState(logicalLeftButton);
