In panel, when label text exceed horizontal and vertical it create auto scroll bar horizontal and vertically. both scroll are link to each other so, when i move mouse scroll (mouse wheel) both scrolled but my requirement is to scrolled horizontally. Is there any way to do that??
I tried this one but it doesn't work....
panel.MouseWheel += delegate (object sender, MouseEventArgs e)
{
((HandledMouseEventArgs)e).Handled = false;
};

I have a winforms application with a parent panel contains PictureBox and Label.
The application has an event on mouse enter on the parent panel to do some animation that hides the picturebox and shows the label.
It also has another event on mouse leave to handle the animation that hides the label and shows picture box.
What's happening is when mouse enters panel, animation kicks in and does what it does, but when the mouse enters label it practically leaves panel and the reverse animation kicks in.
My question is -
how can I prevent mouse leave event when my mouse enters child control of the panel?
Check if the mouse is still in the panel
private void Panel1_MouseLeave(object sender, EventArgs e)
{
if (!(sender as Panel).ClientRectangle.Contains(PointToClient(Control.MousePosition)))
{
//do animation
}
}
I'm trying to find the scroll direction when subscribing to ViewChange event for a ScrollViewer in UWP.
So this event is being called on every scroll that I perform(up and down). I need to perform actions only when scrolling to bottom and ignore when scrolling up. Is this possible ?
private async void OnViewChanged(object sender, ScrollViewerViewChangedEventArgs e)
{
if (!e.IsIntermediate)
{
//here I need to know the scroll direction
}
}
I am dynamically adding buttons to a FlowLayoutPanel, when I scroll using the mouse wheel on the panel the scrollbar value does not change however it still scrolls. When I click on the small arrow to force a scroll the value changes.
I want an event to trigger whenever the value of the scrollbar changes but can't seem to figure out how to, any help is much appreciated.
Probably an oversight by the authors. Not sure what you are doing with the scroll values, but you can just use the MouseWheel event to get the same scroll value:
void flowLayoutPanel1_MouseWheel(object sender, MouseEventArgs e) {
this.Text = flowLayoutPanel1.VerticalScroll.Value.ToString();
}
I'm working on an application where I have a grid of buttons (can be various number of them). Atm I'm using a 4x4 Grid to place them and stretch them to size. The issue is that these buttons can be dragged around, and they should be hovering over the rest of the buttons while they are dragged. They can be also clicked, in which case they slowly hover over to another point on the screen.
The problem arises from the fact that Grid doesn't handle zIndex, and putting a canvas under the Grid wouldn't help. I'm not sure if having a canvas with absolute coordinates would work on different sized screens, and the buttons are also supposed to hover over other elements outside the grid as well (and the grid is in a pivot - the button has to hover over whatever is outside the pivot as well).
The question is if there is any way other than a canvas with zIndex, and if not, how can I achieve a proper Grid-like layout with a canvas.
UPDATE:
I'm using the following code to move the button:
private TranslateTransform dragTranslation = new TranslateTransform();
private void Button_ManipulationDelta(object sender, ManipulationDeltaEventArgs e)
{
if (dragTranslation.X + dragTranslation.Y > 100)
{
//ClickLock to avoid the tap event from firing
clickLock = true;
}
draggedButton.RenderTransform = dragTranslation;
dragTranslation.X += e.DeltaManipulation.Translation.X;
dragTranslation.Y += e.DeltaManipulation.Translation.Y;
}
Note that I've skipped parts such as reassigning dragTranslation in the ManipulationStarted event.
I am creating a plotting program and I was wondering how to move a chart's legend with the mouse? So you would click on the legend and then you could move it anywhere inside the chart area.
Using manual double-buffering of the chart, draw the legend at the current mouse position (perhaps + (15,15)) on the back-buffer just prior to drawing the back buffer to the screen. You can also set an Alpha to make the legend semi-transparent until the user drops it.
You can create a little form without borders to build your legend or use a ToolTip item. Then you could move with mouseMove event:
private void frmMain_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button = System.Windows.Forms.MouseButtons.Left)
ChangeLegendPosition(e.X, e.Y);
}
Where ChangeLegendPosition is your function that updates your form/tooltip position.
