How do I do this? If I cut and paste, then it wipes the code, sometimes the stuff doesn't even show up when I run the program (I guess it's loosing all the handler information) I read about not cutting / pasting controls in the sticky at the top.
View 4 RepliesI am trying to create a way to use my arrow keys to move around some text boxes. The form has 12 textboxes moving from left to right with 4 in each row. Tab Index will be like this.
0 1 2 3
4 5 6 7
8 9 10 11
In the code I have figured out how to find the current tab index but I am having trouble moving to the next control based on which arrow key is pressed. Here is the code I have so far.
Protected Overrides Function ProcessCmdKey(ByRef msg As System.Windows.Forms.Message, ByVal keyData As System.Windows.Forms.Keys) As Boolean
'This variable holds the current tab index for the control that has focus.

I commented the area where I haven't been able to figure out how to code it. I have spent a few days working this out and have spent the past 6 hours working on this part.
I've created a tab control and on one of the pages I added a button, but I cannot move the button around with the mouse!? I can change the buttons position within the tab control page using the property Location and I can size the button using the mouse and the button is NOT locked. I even tried creating a new project with just the tab control and it still does the same thing. I can, tho, move the button using the keyboard arrows!

I'm not seeing anything about event handlers for dynamically created controls.. and I could have sworn I had once before. I did see one post about the topic, but it was just replied by asking for some posted code, so as in a preemptive move..
Private Sub buttonCreate()
Dim newbutton As New Button
newbutton.Height = 39
[CODE]...
Here's what I'm trying...
Private Sub newButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles newButton.Click
End Sub
Here's the errors I recieve...QuoteHandles clause requires a WithEvents variable defined in the containing type or one of its base types
I am coding a dynamic asp.net page in which i want to have text boxes in a page and the number of text boxes depend on a previous user input. Since the number of text boxes are decided dynamically, I am going with designing them in code rather than in the aspx page.Now I need these fields to be mandatory and so want to indicate a RED asterisk symbol in front of the label corresponding to each text box.I am really new to working in .net and I couldn't figure out how to set a specific color to a labelcontrol.[code]....
View 1 RepliesI tried to use this code in the form:
AddHandler MyControl.MouseDown, AddressOf StartDrag
This wont give me an error, but it doesn't happen anything when I mouse down on the Control.
the same doesn't work if I put it in the user control.
Private Sub StartDrag(ByVal sender As Object, ByVal e As MouseEventArgs)
Dim Box = CType(sender, Control)
Box.Tag = New DragInfo(Form.MousePosition, Box.Location)

The following zipped up Visual Studio Solution on Skydrive is immediately buildable and runnable; a usercontrol on a Form. Problem? If you click on any of the Edit Buttons and move the Horizontal Scroll, the values as they change in the Label_Values are off by one when you release the slider button. I think this is a timing problem between the Paint handler and the Horizontal Scroll event handler at the very bottom of the User Control code. Sorry I didn't eliminate

View 1 RepliesI had originally created an "Options" form that had all my different options checkboxes and settings. I am implementing a new layout for the UI and am wanting to move all the contents of the Options form to the main form without having to redo a bunch of code.
I know cutting and pasting will "break it", so I'm not sure how to do it with minimal effort. is this doable?
I would like to learn how to move a control like the visual studio program. In the toolbox you have a list of all your controls (button, listbox etc....). They are labels and when you double click or drag on the label the associated control shows up on the form.
How can I do something like this in my application?

View 2 RepliesI 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

I am creating an application where I can move resize controls around and this way set up an application. I need to know how to select a control (e.g.: textbox, button...) at runtime as I would do in Visual Studio for example.Then once I could do this the next question would be how can I change the icon of the mouse when it goes onto such control?
View 1 RepliesI have a form that has many tabs and I have some buttons just bellow the tabs, but if I could move those buttons and place them inside the tab I would save some space bellow and I could extend on the tabs. So is there a way of moving controls from one tab to another depending which one has focus.
View 6 RepliesIs there any way in c# or VB to automatically move the controls in a panel when the window is resized. I do not want the Anchor property, which only resizes the control. THe use is that controls are added at runtime to the form, and when the locations/values are loaded on a computer with a larger monitor, they are in the incorrect positions.

View 1 RepliesI have a maximized form that has controls at the top of it and a large DataGridView that is docked below all the controls. Its kind of like the Ribbon in MS Office. The controls cover about 1/4 of the screen at the top. I would like a way for the user to click a button to hide all the controls then automatically expand into the place the controls were so the user can view more data in the DataGridView and visa versa. For example, in MS Office Excel you can hide the ribbon by clicking a tiny button that has "^" on it.
I'm not very familiar with all the controls in Visual Studio so I would like to hear some recommendations. Is this situation ideal for a SplitContainer or ToolStripContainer or am I way off base here?

[Code]...
I have been working on a windows form over the last couple days and I have hit a brick wall when trying to move my controls.
I think I have basic understanding of anchoring and docking but I'm not getting the results I'm hoping for so I have attached some screen shots of what I'm trying to do.
It's not about re-sizing more about moving the controls to the outer edges when my form is maximized.

I have an MDI application which uses fixed sized forms. I've started to change the forms to sizeable and anchored the controls so they move when the form is resized. If the child form has a menu this jumps onto the parent menu (as it always has done) but all the controls move up the form at runtime and leave a space at the bottom of the child. If I change the form in design mode to cut through the bottom controls i.e. so the form doesn't appear tall enough, it corrects itself at runtime. Is there another workaround as it looks misleading in the designer.

View 1 RepliesI am wondering if anyone has any idea how to make the controls stack and fill up the available space left by a control if the control is hidden or removed from the UltraGridBagLayoutPanel.
Example:
[Textbox 1]
[Textbox 2]
[Textbox 3]
[Textbox 4]
[Textbox 5]
If I hide [Textbox 3] as of now, it will disperse the space left equally and pad the remaining text boxes with the space. However, I would like it to do this...
[Textbox 1]
[Textbox 2]
[Textbox 4]
[Textbox 5]
Where all the text boxes will move up and [Textbox 4] will completely consume the space left by [Textbox 3].
The sample below does what I want it to do and that is once I've filled the maskedtextbox and press enter it goes and does stuff. However, because the maskedtextbox is full I get an annoying 'beep'. So I figured I'd just use the tab key, I changed theChrW(Keys.Return) to ChrW(Keys.Tab) but it doesn't fall through, it just changes focus to the next maskedtextbox that I have. Is there a way to lose the beep? Or how do I get the tab key to fall through?

I have a datagridview. If the user adds a new row, and then clicks away from the grid. How can i stop them from doing this?
I want them to finish the row add first or cancel it. I want to then update the table adapter in the grid's leave event.
If the row validation fails, i want to display a message and re-focus to the cell in question.
The first problem i am running into is that the focus continues to go to the control that the user clicked on to move away from the grid.
How do i cancel that event?
As an example, if the grid is on a tab page and the user clicks on another tab page, i want to prevent that page from displaying if there is an error on the row that is being added to the grid.
I was hopeing for a cancel option in the lost focus event of the grid.
