Dragging File From One Tabpage Into Another?
Aug 21, 2009
I cannot get the dragdrop event to fire when I drag a file from one tabpage to another tab page in the same tabcontrol. I can drag a file from my application and drop into windows explorer and and then drag from windows explorer into my app. That all works fine. And when I drag from one tabpage up to the top of the control, my program uses the tabcontrols dragover event to swap tabs....works fine also. ...Drag drop event fires...no problems
Say I have a list box with files on one tabpage, a list box with files from a different directory on another tabpage, I want to be able to drag the file over and drop it into the other listbox.I have done lots of testing on the variables in the dragdrop handlers to see if they are recognizing the switch in controls and they are. But the dragdrop event will not fire.

I am using System.Windows.Forms.TabPage to store an entire TabPage for later use in My.Settings. Here is a brief description of the application.
I have a TabControl that has 3 tabs. One for user input, another tab for equipment settings, and then a final tab for Oven settings. On the user input tab, if the user de-selects the checkbox for Oven, the oven tab is saved to My.Settings and hidden.
I can then run the application without oven control. After running, lets say the user would like to re-run, this time with the oven. They go back to the input tab and re-select the Oven checkbox. However, the Oven tab doesn't re-appear. When stepping through the code, the is nothing stored in My.Settings for the oven tab page. Why not?
Also, I can open the application, and check, then uncheck the oven checkbox and the tab is hidden, then returns. I can do this all day. However, after running the tab will not return.

winforms .net 3.5 Ultrawingrid 9.2 In my subclass of Ultrawingrid.Ultragrid :
[Code]...
This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

In previous versions of VB, you could drag or move the form to a convenient spot on the IDE. With 2010 express, the form is in the upper left hand corner and will not move. The toolbox essentially hides it.I have not been able to find a setting that changes this condition.

the user has the option of dragging several pictureboxes around the form. when he lets go of the mouse, the picturebox will take on a new position on the form.
i would like to implement the following:
on mouseup, if the picturebox position is within some amount maybe 50 or 100 (i dont know what units VB.net) uses, i would like it to be dropped exactly in a defined position. sort of like if you play checkers on yahoo games, you dont have to place the piece exactly on the square only approximately.

Right now I have checkboxes on my form, and depending on what check box I check, the value of it gets put into a text box. So if I check "Right Eye", the texb ox below it gets "Right Eye" placed there.
I would like to do away with the check boxes and instead have a new form pop up with a list of words that gets populated from a table. Is it possible to be able to drag and drop these words into a text box? I guess I could use a List Box control for that but I'm unsure how to implement drag and drop. Maybe be able to multi-select words and then drag them all to a certain text box.
I'd like to have give the user the option of adding and deleting words from that form as they see fit, so could I just let VS do that for me by dragging the datasource onto the form and have it create a bindingnavigator or should I do it myself?

I'm working on a little program that uses a ListView box. I'd like to know if you can arrange the list by dragging the items within the ListView box. Example: I'd like to be able to just drag the bottom item to the top, or the middle item to the bottom, and so on. I guess I'm just wondering if I can move items around using the mouse by dragging them around within the ListView box.

After maximizing a form, if I drag the title bar, the form moves out of position. This seems to be normal in windows, since IE does it also, but can I disable this? so the form stays fixed and unmovable?

I want to create a dial which is basically a circle that I can drag around in a circular motion. Ive looked at using the code in an earlier post which allows you to drag items around a screen but I cant figure out how to confine the movement so it only allows the user to drag this circle around in a circular motion. Any coordinate altering I do just looks snappy.

I have a datagridview showing data from an Access database. I have dragged the datagridview from "Data Sources" window - and not written any code. In bindingsource I have choose to sort on an autonumber field. Is it possible to let the user use the mouse to change the order, and the database to remember this the next time the user starts the application.I guess I have to have a number field in the database, and write code to change the value in number field as the user change order - and then save this back to the database? Does the datagridview support changing order by mouse at all?

I know how to drag a file to a listview, my question is regarding folders... How can I add a folder to the listview? I know a folder is not a file, but, is there a way to "recognize" it as a folder and then add any icon in its place?

I don't know if I have gone blind, or if I am just searching in the wrong place, but what is the cursor that Windows uses for standard dragging, and where is it found? I can see the icon that is used when something is dragged over a control that is not a drop target, but not the control that is used for dragging elsewhere.

I am trying to code in .Net to select an area and the area will be where ever in the form, that is not restricted to a control and asusually the area appears like a square by dragging using mouse at runtime on the form and if on clicking on a button for ex "Save" i.e., saving the selected area and when the next time the page loads that particular area should be clickable.Right now i have no idea where to start but if some idea is given it will be more helpful to me to develop some code for this functionality. Does any one give a small idea that how can I do this functionality, so that I can proceed developing code?
