I have added click & drag panning functionality, but the displayed size of the image is limited by the surrounding border, leaving only the top left corner of the image visible when the image is panned. This is the case even when i remove ClipToBounds="True"
ActualHeight and ActualWidth have values corresponding to the image's natural height and width, so why is the image clipped? What can I do to make the full image visible?
If you really want the border to overlay on top of the the image, then put them both in a <Grid> or <Canvas>
<Canvas>
<Image/>
<Borde/>
</Canvas>

I'm quite new to C# so expect faulty/lengthy code for no good reason.
So i was playing around with WPF Applications as i wanted to know how to make a button move when hovered over it- Which i managed to do but now it goes out of bounds?

I set random range from 0 to 250, because when i adjust it to the window's actual height 'n width it goes out of bounds even faster.
For some strange reason when it goes over 230-ish (could be lower) the button is gone until you enlargen the window size.
Did i overlook a vital piece 'o code?

After playing a bit in the designer with different values, it looks like in Grid margins take precedence, and the button gets smaller to accomodate. In case when it disappears, it's calculated height just becomes 0.
Set width and height for the button manually, then change just the left and top margin, while setting rest to 0:
<Grid>
<Button Margin="250,250,0,0" Width="100" Height="100">TEST</Button>
</Grid>
Play with values in designer first to see what's happening when.
Better, do not use an element's Margin for layout. For absolute positioning, use a Canvas:
<Grid>
<Canvas>
<Button x:Name="klikmij" Content="Click me!"
MouseEnter="onMouseEnter" Click="onMouseClick"
Height="33" Width="68"/>
</Canvas>
</Grid>
with thic code behind:
private readonly Random rnd = new Random();
private void onMouseEnter(object sender, MouseEventArgs e)
{
Canvas.SetLeft(klikmij, rnd.Next(0, 250));
Canvas.SetTop(klikmij, rnd.Next(0, 250));
}
I'm using Material design. I created a color picker to choose the color the user wants, after the user chooses the color and theme.
I want to save these settings into a text file on the disk. I don't know how can I convert these types to a list for the string which can I use for reading theme that is saved :
private void MyColorPicker1_PreviewMouseMove(object sender, MouseEventArgs e)
{
string filepath = #"C:\Themses";
if (e.LeftButton == MouseButtonState.Pressed)
{
ITheme theme = _paletteHelper.GetTheme();
theme.SetPrimaryColor(Color.FromRgb(MyColorPicker1.Color.R, MyColorPicker1.Color.G, MyColorPicker1.Color.B)); //red
var Test = theme.GetBaseTheme();
// something here to write all setting inside of ITheme into the text file
//
_paletteHelper.SetTheme(theme);
}
}
How can I do that?

(C # Application for WPF)
I have a problem and I have to "draw" a coordinate system and enter only the coordinates (without lines) as seen in the picture.
I would like to use a library, because I also have to draw a frame and I thought with a library would it be easy.
So I've discovered GnuPlot, Oxyplot and draw myself. GnuPlot is unfortunately stupid since it has no library for a C # application. (Or if you have one, please let me know). Therefore, I used OxyPlot, but unfortunately OxyPlot shows me only the coordinate system.
Now to my question.
Is there anything better to draw coordinate systems with the coordinates?
It should meet the following requirements:
It should be a preview application, that is, if I change the size it should happen directly
I would like to make a frame, so it should help me in the process
there should be a library
it should be for a C # application
I would like to be first point marks for the X, Y coordinates, but later it should be circles with a circle diameter
later as a Bitmap
As mentioned above, I've used it with OxyPlot, but unfortunately it does not draw a graph (I used the sample documentation)
Maybe you have better ideas / a solution for OxyPlot.
Thanks in advance and I am happy about every reply.

Add this code

after this line
InitializeComponent();
and it will show the graph. Also, in order to remove the line and just draw the Markers, use something like this LineSeries:
<oxy:LineSeries ItemsSource="{Binding Points}" LineStyle="None" MarkerType="Circle" MarkerSize="5" MarkerFill="Black"/>

I'v a progressbar and an image.
When Progress Bar value is 50, image loaded by 50%.
I tried to add image as the progressbar foreground, but it have green shade. So ugly.
How can I do this?
To run this sample, you need a snake image which you can get from http://res.freestockphotos.biz/pictures/16/16242-illustration-of-a-green-snake-pv.png. I have used this url directly, but your should download image first and then use it.
You need a control template for your ProgressBar because you want to show percentage status too.
Otherwise normal ProgressBar would do.
Code can be used as is :

i had similar scenario.
if you want the scroll bar to be just a rectangle,
easiest way to make it:
1- add an image to your window.
2- put a grid on it in such a way that the grid hides the image.
3- programatically change the width or height of the grid.
tell me if you needed an example code.
I am using Silverlight 3 + VSTS 2008. I have a image (Multiscale image control) and I place tooltip on this image. The function of Tooltip works fine. Since the image is big (about 500 * 500 size), and since end user could move mouse on the picture, and I want to display tooltip position along with the mouse (i.e. when mouse moves, I want to tooltip move along with the mouse). Currently, the tooltip displays at a fixed position.
Here is my current XAML code, any ideas how to solve this issue?
<MultiScaleImage x:Name="msi" Height="500" Width="500">
<ToolTipService.ToolTip>
<ToolTip Content="Here is a tool tip" Name="DeepZoomToolTip"></ToolTip>
</ToolTipService.ToolTip>
</MultiScaleImage>
I ended up having a similar issue and solved the issue by using a popup. This post contained the core solution. Here is the suggested XAML from the other post:
<Canvas x:Name="LayoutRoot" Background="White">
<Image Source="/pretty-pretty.png" MouseMove="Image_MouseMove" MouseLeave="Image_MouseLeave"/>
<Popup Name="DeepZoomToolTip">
<Border CornerRadius="1" Padding="1" Background="Azure" IsHitTestVisible="False">
<TextBlock Text="Here is a tool tip" />
</Border>
</Popup>
</Canvas>
And here is the suggested, this would go in the code behind:
private void Image_MouseMove(object sender, MouseEventArgs e)
{
DeepZoomToolTip.IsOpen = true;
DeepZoomToolTip.HorizontalOffset = e.GetPosition(LayoutRoot).X;
DeepZoomToolTip.VerticalOffset = e.GetPosition(LayoutRoot).Y;
}
private void Image_MouseLeave(object sender, MouseEventArgs e)
{
DeepZoomToolTip.IsOpen = false;
}
The tooltip control is designed to pop up roughly where the mouse meets the element to which it's bound, and can't respond to move events. Below is a custom tooltip example. I added the background and the z-index so that the TextBlock would appear over the image. The offset from the mouse position keeps the tooltip away from the mouse cursor, so that the movement is animated smoothly.
