Move cursor position during drag drop operation

Posted By:      Posted Date: September 22, 2010    Points: 0   Category :Windows Application


I'm enhancing the behaviour of out of the box WF designer drag/drop experience.  One of the things I'm trying to do (in part) is when a toolbox item is drag over an existing activity designer and then dropped, I want the toolbox item's activity to be dropped close to the activity designer on which it was to be dropped, but not directly on top of the designer.

To accomplish this, I detect when a drop operation is about to occur and then I attempt to move the cursor position next to the activity designer.  The problem I'm having is moving the cursor during the drop operation.  I've tried various ways to do this programmatically, but nothing seems to work.  Or, perhaps it is getting moved but then the workflow designer (and in particular the flowchart designer) does something special with mouse position or otherwise ignores it. 

I started out posting this question on the WPF forum, but now I'm beginning to wonder if perhaps there is something unique to  the WF/flowchart designer that's causing the mouse not to move (or to move back to the original position perhaps) rather than a general issue with moving the mouse during drag/drop operations.

Can anyone provide any guidance?

Move cursor position during drag drop operation



I know how to change to a custom cusor or visual instead of a standard cursor during drag and drop operations.  I know how to get the current mouse position during drag and drop methods (often there is a GetPosition method, or alternatively I can use p/invoke or System.Windows.Forms.Cursor.MousePosition getter).

My question is, how can I (or is it not possible) to change the mouse position programmatically during the drag/drop operation, ideally just before the drop occurs so that items are dropped at the point of the programmatically set cursor position? 

I tried to to use the System.Windows.Forms.Position setter and SetCursorPos both in the source's PreviewQueryContinueDrag handler and the target's PreviewDrop handler but neither affected the position of where the items were dropped.  In the case of PreviewQueryContinueDrag, the mouse visually moved to the programmatic location after the items were dropped, even though the PreviewQueryContinueDrag handler was called before the item was dropped (and before PreviewDrop).

Any ideas?



Changing Mouse Cursor into Crossed Circle in ListBox-ScrollBar/ScrollViewer(on Drag and Drop).

Hi All,   I have a ListBox with 10 items, the automatic Scrollbar/ScrollViewer is appearing. If i'm dragging an item from the listbox and moving the mouse cursor on top scrollbar/scrollviewer the cusor have to change into CROSSED CIRCLE(means its not a location to drop). Can any one help to do the same, or please let me know if more info needed.   Thanks, Karthikeyan Manickam.

IMessageFilter.PreFilterMessage not called during drag-drop operation



I'm hoping someone can tell me why 'PreFilterMessage' on a registered IMessageFilter is not being called during a drag-drop operation?  I need to track mouse coordinates during the drag-drop operation, and I know I can do this with DragOver, but I would like to have a 'global' view of the mouse position, and DragOver needs to be subscribed to on the individual Controls in my GUI.

Is there an alternative way of tracking the Cursor position during a drag-drop operation, or is there any way I can get my IMessageFilter to receive messages during this?

ASP.NET: Web Forms Let You Drag And Drop Your Way To Powerful Web Apps


Web Forms have the potential to change Web programming by introducing a new programming model built around server-side controls-a model in which controls render their own UIs by generating HTML to return to clients and firing events that are handled by server-side scripts. Since all the action takes place on the Web server, virtually any browser can run a Web Forms app. And thanks to Visual Studio .NET, building a Web Forms app is a lot like using Visual Basic: just drop a control onto a form then write an event handler. This article describes the Web Forms programming model, how it fits with ASP.NET, and introduces DataGrid, TextBox, and other classes in the .NET Framework class library.

Scott Howlett and Jeff Dunmall: Drag and Drop Data Manipulation Powered by XML


Building on the browser-based org chart featuring VML (Vector Markup Language) described previously in Microsoft Internet Developer, this article takes you through the process of refining that sample app by using XML, XSL, and JScript code to create a new, improved version. Drag and drop editing is added to the org chart interface thanks to built-in support found in Internet Explorer 5.0. XML and JScript allow data manipulated on the screen to be saved back to the server in its native format. The final product of this combination of XML, XSL, and VML is a high performance, scalable Internet app that uses processing on the client to reduce stress for the server.

Can't start crawl becasue of index move operation


Hi there,

I can't start crawl task. The log says that "Deleted by the gatherer (The start address or content source that contained this item was deleted and hence this item was deleted.)" But I did not change the path of content sources and When I trie to start crawling job it says "Crawling might be paused because a backup or an index move operation is in progress. Are you sure you want to resume this crawl?"

What is index move operation? What should I do? I'll really appreciate the solution greatly. Thanks in advance.

Listview - Drag and Drop?


Hey everyone, I have a treeview and a listview on my ASP.NET application. However, with treeview I can drag and drop it to where ever I want it on my page. I tried this with listview, but it wouldn't let me. Listview automatically positions itself along the left side of my application. What I'm wanting to do is put my treeview along the right side and then put my treeview along the left side of the application. Any ideas on why I can't do this or suggestions on how I might be able to do this?

By the way, I'm running Visual Studio 2010 and using .NET FRAMEWORK 4.

Drag and Drop data binding and Enums

I'm using Visual Studio 2010 to design a simple WPF application. I created a simple class, with some Enum property, and added the class as a new data source, then dragged and dropped it from the Data sources window as a DataGrid. The result is a data grid that works properly, except for enum handling. Obviously, I want enums to be displayed as combo boxes, so I set the option. The problem is: I get a combo box column, but it is NOT populated with the Enum's values, instead only the current value is displayed and the user can't change it. This behavior seems completely useless to me. Am I doing something wrong here, or is there another explanation for this? Why isn't the designer handling enums in a sensible way? Another problem is, if I choose to drag the class as "Details". Again everything works except enums. I get a standalone combobox, but it displays the values of the property from the entire list, and choosing a different item in the combobox changes the active bound property. Once again, useless behavior - I expect the designer to create a combobox populated with values from the Enum, and for it to act like every other control in a master-details relationship - choosing a different value changes the state of the current item. Please advise.

GiveFeedback @ Drag and drop

Hi guys, i setup a little test app. There is only a stackpanel with some buttons and a black rectangle... Its possible to drag and drop the rectangle into the stackpanel! Now i would like to provide feedback to the user! The ui element in this case the black rec should be placed near the cursor... Exmaple: http://livedocs.adobe.com/flex/3/html/help.html?content=dragdrop_7.html I don't have a idea todo that... please help me with some nice code! thanks :) private Point startPoint; public MainWindow() { this.InitializeComponent(); rect.PreviewMouseLeftButtonDown += (s, e) => { startPoint = e.GetPosition(null); }; rect.MouseMove += (s, e) => { Point mousePos = e.GetPosition(null); Vector diff = startPoint - mousePos; if (e.LeftButton == MouseButtonState.Pressed && Math.Abs(diff.X) > SystemParameters.MinimumHorizontalDragDistance && Math.Abs(diff.Y) > SystemParameters.MinimumVerticalDragDistance) { Rectangle r = s as Rectangle; DataObject dragData = new DataObject("rect", r); DragDrop.DoDragDrop(r, dragData, DragDropEffects.Move); } }; stack.AllowDrop = true; stack.DragEnter += (s, e) => { if (!e.Data.GetDataPresent("rect") || s == e

Drag Drop adorner visual performance

Hi, I've been modifying my application based on a MSDN blog post on WPF drag and drop.   While I found the blog post very helpful, what I've noticed when trying to use a visual for a drag indicator (rather than either a default or custom cursor), is that the visual doesn't 'keep up' with the cursor movement.  That is, if I move the mouse quickly during a drag/drop operation, there is a space between the visual adorner being moved around and the cursor.  When I stop movement (but still have the mouse button down so the drag/drop operation is still active), the visual 'catches up' with the standard cursor.  And if I were to move the mouse slower, then the standard cursor and the drag drop visual positions are kept in sync. This lag between the movement of the 'real' cursor and the visual is even more obvious in my application than in blog post sample application, although it is present in the sample application as well.  My question is, is there anyway to improve the performance of a custom drag drop operation using a visual such that I can quickly move around the mouse and not see a gap between the cursor and the visual? Thanks, Notre

Could not complete cursor operation because the table schema changed

Microsoft SQL Server  2000 - 8.00.2039 Got this error: Could not complete cursor operation because the table schema changed after the cursor was declared. SQLCode: 16943 SQLState: HY000 Is this a known issue?  I suspect the application logic may cause this error. Please advise. Thanks a lot!  

Drag and Drop

Hi,   I have been trying to implement drag and drop in my ListView for a while now. There's a number of examples floating around but none of them have really been working for me. I have manage to combine MouseLeftDown and MouseMove to make it possible to drag one item. However, when multiple items are selected it only drags one item (since it changes selection when the MouseLeftDown is triggered).   I haven't stumbled upon a good solution to this yet. I need to be able to drag one or more items and drop them either in the listview itself or some other control. I want a visual indication of the items being dragged as well as some sort of line to tell where the items will be inserted into the listview.   Does anyone have any suggestions on how to go forward? What magic with the mouse events should I preform?   Thanks!
