I have a ScrollViewer control in my window and I would like to hide it when the user cannot scroll down the page. Just like with the horizontal scroll viewer. here is an example:
so here both scrollers are visible because scrolling is enabled:
if I collapse some of the columns of my listview note how eventually the horizontal scroller disappears:
Now note what happens with the vertical scroller:
so far its visible and that's ok because not all the content fits in the page. But let me maximize the page and co-lapse all the group boxes so that all the content fits in the page:
Why is it visible if it is not possible to scroll? I set all the group boxes height = 0 except the last one and the vertical scroller still shoes up? The horizontal scroller disappeared when it was not possible to scroll any more. Why does the vertical scroller does not behave the same way?
What can I do to make it invisible when it is not possible to scroll?
Make sure that your Scrollviewer's VerticalScrollBarVisibility = ScrollBarVisibility.Auto;

I have a navigation panel on the left hand side of my program and I'd like it to always stay where it is when scrolling the window content. Is there a way to do that?
I've thought about trying to do a get/set for its position but there's only a size property.
In the example above, the information in the top left is in a panel. Is there a way to keep it anchored there as the user scrolls down?
You currently appear to have the Autoscroll option enabled on the Form. Set that to false, then set up two panels, one for the toolbar/navigation and the other for the scrollable content.
Set the toolbar panel to be anchored to Top, Bottom, Left. Set the content panel to be anchored to all four sides. Set both panels to Autoscroll=True, then put the content in each panel. When each panel gets too small to contain their contents they will scroll - independently - which will in most cases mean that the toolbar/navigation will stay put while the content will be scrollable. If the toolbar panel also gets too small then it will be scrollable too:
I am trying to align few buttons and a textbox, like the Google Chrome browser address bar, which stretches itself when the user maximizes windows form.
I tried anchor and dock, but 1st control from the left and last control from the right side align themselves but other middle controls stays put.
Please anybody tell me how to properly align controls?
Here's my controls in panel:
After stretch:
Don't use Dock property. For the controls before the TextBox, leave the Anchor property to default, i.e., Left, Top.
For the TextBox, set the anchor to Left, Right, Top.
And for controls after the TextBox, use Right, Top.
This will resize only the TextBox when you change the window size.
When I add controls dynamically in flow-layout panel using C# it goes out of the area. So I need both horizontal or vertical scroll to make them responsive. Can you suggest to me the properties, or a way how to make a dynamically added list box in flow layout panel responsive, so that when I change the size they become responsive.
Just add the auto-scroll property to true like this:
flowLayoutPanel.AutoScroll = true;
I'm working on a winforms User Control . There are several grids on it. Some of them are horizontally aligned and some of them are vertically aligned.
I'm embedding the User Control in a Form and i'm setting
this.Dock = DockStyle.Fill;
On the run, i want the grids to be scaled horizontally or vertically when fulscreen or minimized screen but i see the absolute heights and widths of grids. For example in minimized screen only the grid on the left is visible and when I make fulscreen I see the right grid.(the same for above and below grids)
How can I make them to be scaled relatively whatever the ecreen size is?
You could separate the grids with SplitContainers(Just nest as much of them as you need). Set FixedPanel to None so that the panels in the splitcontainer are sized relatively to each other. Set IsSplitterFixed to true to prohibit manual resizing. When you anchor your grids to all sides or set DockStyle to Fill you should get what you want.
Is it possible to set the number of logical units the ScrollViewer should scroll when either clicking the arrows of the scrollbar (line up, line down) or inside the scrollbar (page up, page down)?
You can try this:
ScrollBar verticalScrollBar = scrollViewer.Template.FindName("PART_VerticalScrollBar", scrollViewer) as ScrollBar;
verticalScrollBar.SmallChange = 5;

Other than that, I can't find any out-of-the box solution without you rolling your own.
