OnDrop Method—ArcGIS Pro

Invoked when an object is dropped onto the pane. Implement this method to add class handling for this event.

Syntax

C#
Visual Basic (Declaration)

public virtual void OnDrop( 
   DropInfo dropInfo
)

Public Overridable Sub OnDrop( _
   ByVal dropInfo As DropInfo _
)

Parameters

dropInfo: The data being dropped.

Remarks

Panes and DockPanes that have registered themselves as drop targets (DAML isDropTarget) and have set DropInfo.Effects appropriately in OnDragOver, are automatically called by the framework whenever an object is dropped on them.

public override void OnDrop(ArcGIS.Desktop.Framework.DragDrop.DropData dropData) { foreach (var item in dropData.Items) { if (System.IO.Path.GetExtension(item.Data as string) == ".txt") { item.Handled = true; ReadTextFile(item.Data as string); return; } } }

Example

public override void OnDrop(ArcGIS.Desktop.Framework.DragDrop.DropData dropData)
{
  foreach (var item in dropData.Items)
  {
    if (System.IO.Path.GetExtension(item.Data as string) == ".txt")
    {
      item.Handled = true;
      ReadTextFile(item.Data as string);
      return;
    }
  }
}

Requirements
