I need to add vertical and horizonatl scrollbars to my windows form application. I have set the AutoScroll property of the form control to true and also set the AutoScrollMinSize property bigger than the form size. The scrollbars appear in the design view, but when I run my project they do not appear.

I have ComboBoxes and DatagridViews for which I've written code to automatically adjust the width of the ComboBox dropdown list or DataGridView columns depending upon the available space for them and certain conditions.The problem is when a vertical scrollbar appears. I then need to adjust for the width it takes, but am not able to find how to detect this using code.Ive been looking at .ScrollBars, but with this I can only set/get for them to be able to be there or not.
For the ComboBox:
-How can I detect if it has a vertical scrollbar before opening its dropdownlist, if at all possible?
-If not, how do I check using code if it has a vertical scrollbar?
For the DataGridView:
-How do I detect using code if it has a vertical scrollbar
I set the Scrollbars property of textbox to ScrollBars = Both but the textbox shows only the vertical scrollbar. (i already set the Multiline = True)
View 2 RepliesI have set a rich text box into a form,a button & another text box
converting vertical data into horizontal i.e when i click on the button all the vertical values of rich text box should get converted into horizontal line in text box
I'm having trouble finding a property of the DataGridView that allows me to turn on both Vertical and Horizontal Gridlines. Does this exist? I can't imagine it not existing but I can't seem to find it.
View 4 RepliesThe scroll bars actually move now, They just move the wrong thing. When I click the Horizontal bar it moves the picture box to the left part of the screen and I can scroll the box back and forth. If I click the Vertical Bar it goes up to the top and I can move it up and down. So if I click both of them, the picture box goes to (0,0) of the form. It wont move the image inside. I can't figure out how to assign the scrollbars to the image instead of the picturebox.
Try making a form with a Picturebox, Vertical Scrollbar and Horizontal Scrollbar in it and rename all your stuff the way I got mine:
Horizontal Scrollbar = hsbPicMap
Vertical Scrollbar = vsbPicMap
Picturebox = picMap
Set the image property in the properties box to whatever you want. Try to make the picturebox of fairly big size. Mine is set to 656, 528 in pixels, and the location is 152, 72 on the form. The image I am using is about 1500, 1200. The bars are on the right side and the bottom of the picturebox.
Code:
Public Class frmMap
Inherits System.Windows.Forms.Form
Private Sub HSBpicMap_Scroll(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ScrollEventArgs) Handles hsbPicMap.Scroll
picMap.Left = -hsbPicMap.Value

I would like to have the tabs on my TabControl displayed on the left, or sometimes right. Unlike the System.Windows.Forms.TabControl, however, I would like the text to remain horizontal instead of being rotated by 90 or 270 degrees to the horizontal. Here are a couple of pictures illustrating the concept. Though I could write code to do this myself in about an hour or two, I just thought I'd ask first if there is any existing Winforms control that implements such feature.

I'm having a problem assigning the arrow keys to the right scrolling events.I have a VScrollbar and an HScrollbar. I want the left / right arrow keys to scroll the horizontal bar, and the up / down arrow keys to scroll the vertical bar. The default behaviour seems to be that the first created of the two (VScrollBar or HScrollbar, depending on order of creation) received all arrow key events as a Scroll event. So when I push up / down / left / right, it is my VScrollbar that moves (HScrollbar might move also with the left / right arrow keys, I don't remember). I tried catching the KeyDown event on my form, to manage the left / right / up / down keys myself, but apparently the Scroll events are triggered first...In any case, what would be the "right" way to use a vertical and horizontal scrollbar and have the arrow keys do what they're supposed to do in VB. NET?

View 2 RepliesI have the following code to resize the datagridview but the vertical and horizontal scroll bar are not shown when there are colunns and rows exceed the width and height of datagridview objects.Bascially the following code is similar to dock to the botton, the only difference is docking to the botton change the Y position of datagridview and fill the botton section whereas my code fix the Y position of datagirdview and fill the bottom.[code]I have tried with the dg.ScrollBars = ScrollBars.Both but it it is not working as well..May i know how to get both scroll bars working.

I'm trying to make an MDI TabControl Container usercontrol, which is used instead of the MdiClient control in an MDI application. Instead of MDI Forms, you can use (modified) TabControls that behave like (maximized) MDI Forms in a Tabbed environment.
A great example is of course the Visual Studio IDE. Each window is just a TabPage on a TabControl (at least it looks like it is, I don't know exactly how it works in the IDE.. but let's assume it is).Now, the VS IDE uses some great functionality which I believe is called TabGroups. By Right-clicking (or dragging it into nothingness) a TabPage 'header', you can choose New Horizontal / Vertical Tab Group, which splits the 'container' into two TabControls, each with their own TabPages, with a splitter in between so you can resize them.
I have been trying to recreate this behaviour, and I must say it works pretty well so far for very little effort. The only (major) downside is, it only works for Vertical OR Horizontal TabGroups. I have no idea how I can possibly make it work using both vertical and horizontal TabGroups simultaneously...
What I did is pretty simple: I have a mdiTabControlContainer which is just a blank UserControl. I made a public property TabControls that returns a (custom) mdiTabControlCollection (inheriting from a generic Collection(Of mdiTabControl) which is basically just a collection of my tabcontrols.
When the collection is modified, I call a RedrawTabControls method which first clears the Controls (deletes all TabControls), and then adds them one by one. First the last in the collection (docked Fill) then the rest docked Left. I also add a splitter between each TabControl. (Code at the bottom)If I dock the TabControls to "Top" for example, I can make it Horizontal. But I have no idea how I can possibly dock a few of them to Left and the other few to Top...? I would need some kind of property that determines which TabControl should be docked where, right? But how and when would I set that property?
The code I'm using now is:
vb.net
Imports System.Collections.ObjectModel
Public Class mdiTabControlContainer
Public Sub New()
[code]....
Now, I allow the user to drag the ToolStrip to the bottom and sides of the form. But when they drag it to the sides, the ToolStripPanels become completely stretched because the text is still drawing horizontally. I know I can set the TextDirection property to make it draw vertically, but I can't figure out how to check the current position of the ToolStrip, and when to check it (which event?)
I have tried the LocationChanged event and did this:
vb.net
Private Sub ts_LocationChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)

With no answers from Google and not finding the answers by searching, just curious as you were to go about simply giving a ListBox a horizontal scroller once it passes its visible border the same as the vertical does?
View 3 RepliesThe 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
