TreeView DragDrop Not Working In Citrix?

Dec 10, 2009

I have a treeview dragdrop event written in VS2003. It works perfectly fine when the application is running on desktop, until we move the application to Citrix. So, users are now running it off from Citrix, the DragDrop event doesn't work anymore. It doesn't even have the effects of allowing dropping.

Listview DragDrop Multiple Items Not Working?

May 6, 2008

I trying to do a drag drop from a listview in one form to another instance of the same form (same application running twice).I have it working with single items selections, but I want to make it work with multiple selections. 289508(VS.71).aspxThis works if I drag/drop onto itself (the same form), which I don't want, but I need it to work across instances.During debugging it seems the code DragDrop code just quits at the line during the drop:Dim myItems() As ListViewItem = e.Data.GetData("System.Windows.Forms.ListViewItem()")Any ideas what is wrong or how to drag/drop multiple items in a listview between apps?

here's my code:
Private Sub ListView1_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles ListView1.DragDrop

.net - Event Fired In Dragdrop Source When Dragdrop Is Completed Or Cancelled?

Nov 28, 2011

I know that there is usually a DoDragDrop method that starts a drag and drop operation. And that there are events (such as DragEnter, DragOver, DragDrop, DragLeave) that can be handled on the target side.

Are there any events on the source of the dragdrop that will tell me whether the dragdrop operation was completed, or possibly cancelled?

Checked TreeView Control Not Working

Aug 18, 2009

I have a treeview control with check boxes. when I check the parent node, all the children check too. The problem is, I want the parent check box to automatically uncheck if one of the children is unchecked.

Private Sub TV_Communities_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TV_Communities.Click
For i = 0 To TV_Communities.Nodes(0).Nodes.Count - 1

Treeview Node Indexof() Not Working?

Sep 29, 2009

I have created an object hierarchy with nested generic listof() structures. I have created a treeview to match and graphically show the structure. I needed a way to show a property box of an object represented by the selected node on the treeview. So, I gave each of my objects a NodeIndex property, in which I would store the treeview.indexof(node) result, as shown below:

For Each oObject In oJob.ObjectListOfCollection
tnode = New TreeNode(oObject.Name)
Treeview.Nodes.Add(tnode)

[2008] DataGridView DragDrop Into New Row?

Jan 15, 2009

I am dragging and dropping values from a listview to a datagridview cell.In the datagridview I have AllowUserToAddRows = True because I want them to drag in as many items as they need.

The problem is that when I drag an item into the new row a newer row is not created below it as it would if I had typed something int he cell and left.

I tried to add a new row on the CellValueChanged event but that inserts a row above the row that I just dragged to.

Anyone know how to trigger that event after a drag and drop?

Move FlowPanelLayout Controls Via DragDrop

Apr 23, 2012

I have a FlowPanelLayout that can contain several UserControls called DataGridViewFilterSortElement. These controls look kind of like buttons, but different. I want the user to be able to click one of the DataGridViewFilterSortElement controls and drag it to another position (index) in the FlowLayoutPanel. Is there a way to see the control physically moving as the user drags it to another position? In other words, is there a way to take a "snap shot" of the control that is being dragged (instead of a shadowed box) which would show the actual control moving as the cursor moves?

Also, as the control is being dragged I'd like to have the other controls position to shift automatically instead of waiting for the user to drop the drag to see the shifts. For example, let's say the FlowPanelLayout contains 3 controls and the user wants to drag the first control to the third controls position. So the user clicks and holds the first DataGridViewFilterSortElement, then drags over the second control, which causes the second control to shift to position 1 of 3, then the user drags over the third control, which causes the third control to shift to position 2 of 3, then the user drops the control in position 3.

Here is a short little video that shows what I want to do: Video Example
Private Sub lblDescription_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown, lblDescription.MouseDown
' if the user left clicks and holds the element begin a DragDrop action
If e.Button = Windows.Forms.MouseButtons.Left Then
Me.DoDragDrop(Me, DragDropEffects.Move)
End If
End Sub

DragDrop Control - Fails To Copy Files?

Mar 10, 2009

I am new to vb.net and development in general. The basics are I have a control that accepts dragdrop, I use this control to drag files onto - based upon the text contained in a combobox the directory path is built in the dragdrop event, and I initiate System.IO.File.Copy. I then refresh my listview, which is working well and is listing files based upon the content of a directory. Here is my code for the dragenter and dragdrop subs

Private Sub pnlDataDrop_DragEnter(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles pnlDataDrop.DragEnter
If e.Data.GetDataPresent(DataFormats.FileDrop) Then
e.Effect = DragDropEffects.Copy
[Code] .....

I have added some break points so that I can see the values for targetpath and myfiles(), and all looks ok. The app is in its very early stages, so I am only testing in the development environment at the moment. So you know, the targetpath is a UNC: \myservermydirectory.

ListView DropHighLight (DragEnter Or DragDrop Event)

Mar 15, 2012

In old vb6.0 it was easy to highlight the target item, where to drop those dragged rows.

Private Sub listView_OLEDragOver(Data As MSComctlLib.DataObject, Effect As Long, Button As Integer, Shift As Integer, x As Single, y As Single, State As Integer) Set listView.DropHighlight = listView.HitTest(x, y)

You can get the item to drop to in VB.NET:

Private Sub ListView_DragDrop(ByVal sender As Object, ByVal _
e As System.Windows.Forms.DragEventArgs) Handles _
ListView.DragDrop

[CODE]...

Now we got the index and item, where to drop. But then what? One possibility to do the HighLight is change the ListViews state to "LVIS_DROPHILITED" by sending Windows message "SendMessageA(lvw.Handle, LVIS_DROPHILITED, 0, 0)". But when is the right time to do that (DragEnter or DragDrop event) and what are the right parameters? Didn't succeed on that yet.

Drag And Drop - Change Cursor As Feedback In DragDrop

Mar 5, 2011

Working on a DragDrop application. I have a class object (built as an object) which has a GroupBox that is enabled for DragDrop.

In the class I have set it up so that the cursor will change when it enters the groupbox, leaves the groupbox, mouse is down within the groupbox and drag/drop is working. I also set up a label in the class object and changed the text in that label as well. Basically, the text changes in the label as expected including 'FEEDBACK' appearing when I am dragging the object BUT the cursor stays stubbornly as a pointer. This is tghe state of affairs either when I debug the class or when, after I build the class, it is run as part of the main program.

Here are the subs set up in the class.

Private Sub GroupBoxSourceMouseDown(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GroupBoxSource.MouseDown
GroupBoxSource.DoDragDrop(GroupBoxSource.Text, DragDropEffects.Copy)

DragEnter And DragDrop Events Fire Multiple Times In VB?

Jul 8, 2010

I've got a research application that is hosting a webbrowser control and I'm implementing a feature that allows the user to select text from a web page and drag it to various research note fields. The issue I have is the dragenter and dragdrop events continue after the initial drop, inserting the text multiple times. Here's the test case on my box and the result.

Select Text in Browser Drag to Text Box Drop Text What happens is after the drop event is fired and the text inserted to the drop target, when you move the mouse after dropping the text, the drag enter event is fired, followed by the dragdrop event, then another dragenter and dragdrop. So, selected text such as "Selected Text" becomes "Selected TextSelected TextSelected Text".

Note: The dragenter event is properly raised once when the mouse enters the textbox, however the mouse does not have to leave the textbox after the dragdrop event fires. i thought there was something wrong with my application so I created a simple test app, containing a Webbrowser and a multi-line text box. This test app generates the same results and the code is below. This is the first time, I've implemented
drag and drop operations and I followed the guidelines noted in this MSDN article. While I did what the article suggests, I'm thinking I need to note the event was handled somewhere.

Asp.net - DragDrop Event Not Firing On Object Inside Usercontrol (but DragEnter Does)

Feb 12, 2012

Well the title pretty well describes my problem. Here is a little bit more detailed description of my problem: I am building an application with a TabControl, which I populate at execution time with TabPages. In my first version of the code, these TabPages were filled with a children ListView. The ListView was also created in code, using AddHandlers to link it to the DragEnter and DragDrop routines. Everything worked very well... Now as I need some other controls on every TabPage, instead of creating every single control in code, I have created a UserControl containing a ListView and a few Buttons, which I instantiate for every new TabPage. The problem now is that the DragDrop event is not raised anymore

VS 2010 TabControl With DragDrop Not Raising MouseClick Events On Tabs

Aug 29, 2010

I have a custom (inherited) TabControl which adds Drag/Drop functionality to it, so that one can drag the tabs around, either within the same control (to re-order them) or to and from other TabControls. I've noticed some time ago that my TabControl however was not raising its MouseClick and MouseUp events (or actually: it is not calling its OnMouseClick and OnMouseUp methods, which comes down to the same thing). I've been struggling with this problem for a long while and I finally figured out what is happening. I'm no closer to figuring out what to do about it though... The problem seems related to the drag drop functionality. I have this code in the OnMouseDown method (which is raised as usual):
