I am loading several command buttons into it (one in each grid box). I have the panel set to autoscroll. When TableLayoutPanel is set to AddColumns, all works well. However, I dont want horizontal scroll, I want vertical. When I set TableLayoutPanel to AddRows, a vertical scrollbar will not appear.

I have a textbox that shows events on a program, which I add. I use the 'scroll bar' option on the textbox to show the vertical scroll bar, but how do I make it stay at the bottom most possible? I am using this code while I am trying to learn how to do what I want the scroll bar to:[code]But how do I get it so the scroll bar will stay at the bottom-most it can? I'd like the newest, most recent events to appear at the bottom of the textbox, and to have the user not have to scroll down every time something new is added.
View 2 RepliesHow would I leave the vertical scroll position as it is and set the horizontal scroll position all the way left if it isn't already in that position? I've been using Me.AutoScrollPosition and have come up with code that is satisfactory but I haven't been able to always leave the vertical scroll position exactly as it is and just move the horizontal scroll position to the left limit.

I have set the panel to autoscroll and added scroll bars but they do not scroll far enough... They only scroll about 2cm.

I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.

View 2 RepliesIn VB 2008, if one drops a vertical scroll bar on a form, by default the maximum value is 100, the minimum value is 0. If you place code in the scroll event to put the scrollbar value in a label, then run the program, the values in the label will range from a low of 0 (expected) to a high of 91 (unexpected).Why is the maximum value displayed in the label at 91 and not 100?

View 3 RepliesHow can I programatically control the position of the vertical scroll of a DataGridView? I need to keep visible the last row added to a table and showing as the last row at the bottom in the DataGridView control so the user doesn't have to be scrolling down every time to see a new row that has been added.
I can see the use of the Offset for the Horizontal Scroll Bar but for the Vertical Scroll bar of the DataGridView it can only be "Get" but not "Set".
I've got a vertical scroll bar and I noticed that it's .Value is at a minimum when the bar is at the TOP (Why is that anyway?). Well, for visual feedback purposes I need it reversed where .Value is the max when the bar is at the top. Now I realize I can just manipulate the .Value in the software to get what I want but I was just wondering if there was a property I could set to just reverse it. I looked at the Object browser and couldn't find one. Sorry about these simple questions it's just that there are SO many properties and methods to learn...and I'm amazed anyone can remember all of these....
View 3 RepliesMy rich text box overflows with output during execution, thus activating a vertical scroll bar. When the program ends the created text box information disappears.I have tried a message box prior to exiting the program to stop execution but then nothing responds until the message box is A instruction doesn�t accomplish my goal either. I see nothing in the text box properties window which looks like it would do the trick and no luck with Googling for info so far.

I have a windows form which contains a group of panels in a flowlayout control. Each panel has a button acrossthe top which is always visible and clicking on it expands the panel to view the other controls on it. clicking on it again shrinks the panel back to the size of the button. A simple form of menu. The flowlayout control has autoscroll enabled and as enough panels are resized (opened) they obviously are too big for the form and a scroll bar pops up.To get the most recently opened panel in the viewable area I use
FlowLayout.ScrollControlIntoView(pnECBF)
where pnECBF is the panel just resized. This works but places the panel at the bottom of the form i.e just in the visible area. I want the user to be able to see the panel AND the next menu button which is on the subsequent panel. So basically what I want is the panel into the visible area +25 pixels for the next panels menu button.

This is for a mapping/plotting program.
t.panel is the main panel and it has too much content to fit in one screen so there are scroll bars. x.panel contains the horizontal scale for the data points in t.panel. I drew the scale using a bitmap and set it as x.panel's background.
Setting x.panel's horizontalscroll.value = t.panel's horizontalscroll.maximum doesn't seem to work. I think this is because x.panel's doesn't have any content that causes it to need scroll bars.
I have a tab control with two tab pages. One page has the auto scroll enabled since there is to much content in the page. The middle mouse wheel doesn't scroll the scroll bar; I have to actually click and hold the scroll bar and drag it down to scroll. Is there a property to allow this?
