Whenever I try to run the WPF application I am getting the following error:
Cannot create instance of 'Window1' defined in assembly 'C1WPFGrid, Version=1.0.0.0,
Culture=neutral, PublicKeyToken=null'. Exception has been thrown by the target of an
invocation. Error in markup file 'Window1.xaml' Line 1 Position 9.
Am I leaving out any declarations ? Please advise !

This normally means that there's a bit of a binding problem going on here. Take a look in the Output window to see if anything's causing a problem - also, set a breakpoint on the InitializeComponent method.

The delrations in XAML are like theis :
<Window x:Class="Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="CIWPFGrid" Height="346" Width="628" xmlns:c1grid="http://schemas.componentone.com/wpf/C1DataGrid" WindowState="Maximized">

In addition to Pete's suggestions, I would try removing elements from the
window and adding them in one at a time until it breaks. XAML makes that
an easy process.

Hello,
I am trying to convert some vector based objects into a raster bitmap.
I manage to do that, but the result is blurry, meaning, edges are blurry instead of jagged.
I assume an anti-aliasing algorithm is applied, but I do not want to be applied...
here is my simplified code in which I draw a circle and make a raster out of it to an Image Control:
DrawingVisual drawingVisual = new DrawingVisual();
DrawingContext drawingContext = drawingVisual.RenderOpen();
drawingContext.DrawEllipse(Brushes.Red, new Pen(Brushes.Red, 1), new Point(50, 50), 50, 50);
drawingContext.Close();
RenderTargetBitmap bmp = new RenderTargetBitmap(180, 180, 96, 96, PixelFormats.Pbgra32);
bmp.Render(drawingVisual);
_image.Source = bmp;
Here is an image to make it clearer.
What I want is the jagged edged circle...
Sample Image[^]
Does anyone have any idea why this happens???
Thanks!

Hi.
How can we get position of Mouse Cursor on Desktop in WPF and C# ?
Thank you.
|
|
|
|
|
Listen to the MouseMove event.
|
|
|
|
|
You're right, but when the Mouse Cursor is away of our window , we can't get the position of it .
I've wanted that.
|
|
|
|
|
How about the Mouse class[^]?

I am almost thinking about WPF but from what I have seen so far (very shallow only) it seems to be all about binding. I hate binding, one of the first utilities I wrote was a BindForm which takes a datarow and a form and loops through the controls and containers on a form looking for control names matching the columns of the datarow and binding them. That was years ago and have hardly looked at binding since.
So all my dialog forms take the same steps
populate the combos
Get the datarow
call BondForm(this, drData)
Can this be done in WPF?
Is it reasonable to do this or is it defeating the purpose of WPF?

While you could do this, you really are defeating the purpose of binding in WPF here. It's a whole different beast to what you got with WinForms and ASP.NET - it's far more powerful. Here[^], I demonstrate binding in ASP.NET, versus WPF to demonstrate binding at a very basic level. If you follow my blog links, I talk about binding in more detail.

Yeah, that's what I thought, I must admit I'm all about the data, and battleshit gray screens are just fine by me. Ah well, every thing changes I guess.
If I pursue this, at least there seems to be plenty of quality resource here, thanks

To be fair though, battleshit gray doesn't cut it any more ... at least from a users point of view.
