I am making my first WPF window. I placed a grid onto it and divided the grid into rows and columns that resize automatically if window is resized. There are two buttons that fill two of grid's cells. The buttons contents is set to "OK" and "EXIT" respectively. What I have some difficulty to understand is why would these buttons only work if I click on the text but won't react if I click on the area that is around text and still is inside respective button. Is there a way to make it possibe to click anywhere on the button and it will press down (even if I click somewhere long way from the text)? Any help would be appreciated, thanks!

Instead of setting Background to {x:Null}, set it to Transparent.
Setting background to {x:Null} makes surrounding area non-clickable.
Null background does not respond to mouse events.
Refer to this for more details - {x:Null} Vs. Transparent.

I'm trying to develop an ancient form of chess, Chaturaji, as an assignment for school. I've got some very basic xaml setup that should allow me to drag and drop an image element within a grid.

When I try to drag the image over the grid the mouse shows the “Drop Not Allowed” cursor and releasing the image does not fire the Drop event. I asked a teacher about this and she said it was probably because I did not set a background for my grid.
I quickly updated the code, but no luck, the event still did not fire. She didn't really know what was going on and told me to email her if the problem persisted.
I thought I would ask here first.
Thanks in advance for any help.
A quick glance at the MSDN UWP Drag and Drop page suggests that you need to handle the DragOver event, and indicate what drop operations the control will accept (true in any form of XAML and IIRC winforms etc. as well). In UWP, that's the AccepttedOperation property on the event args object (WPF calls that property Effects and it's a different enum type):
private void Grid_DragOver(object sender, DragEventArgs e)
{
e.AcceptedOperation = DataPackageOperation.Copy;
}
What I try to achieve is being able to drag an image from one cell and drop it into another cell in the same grid. This grid in xaml is defined as below:
<Grid Grid.Row="1" HorizontalAlignment="Center" AllowDrop="True" VerticalAlignment="Center" >
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Image Margin="10,10,10,10" CanDrag="True" Grid.Row="0" Grid.Column="0" Source="Assets\mock.png" Width="64" Height="64" DropCompleted="Image_DropCompleted"/>
<Image Margin="10,10,10,10" CanDrag="True" Grid.Row="1" Grid.Column="1" Source="Assets\mock.png" Width="64" Height="64" DropCompleted="Image_DropCompleted"/>
<Image Margin="10,10,10,10" CanDrag="True" Grid.Row="2" Grid.Column="2" Source="Assets\mock.png" Width="64" Height="64" DropCompleted="Image_DropCompleted"/>
</Grid>
When I drop an image from one cell to another, Image_DropCompleted is triggered, and I can use static function in Grid to set the row and column index.
So my questions is how to calculate these indexes from current mouse position?

Problem with this window is this components (label and buttons with their contents) does not scale properly. What I want is, when I resize the window I want this components to be proportional to window. Not sure if the grid layout is problem, but how can I fix this components scale properly.
EDIT:
Ok, so I followed your instructions and I like the results (everything seems to scale good enough),
but I have two more minor problems:
1) With a new changes to XAML code, my last button is colliding with the south border of the window, which is not what I want. What I want is an empty space with size of almost exactly (if possible) or close space, like between Label "Title" and north border of the window.
I found solution by defining a new line at the end <RowDefinition Height="*"/>. Not sure if this is a correct way to go.
2) Thus, so far I understand that , 1, 2*,... multiplies the current size. However, it seems I still feel like I don't fully understand it. Currently, I am asking myself, how can I now change the size (width or height in some case) of the button components inside grid layout?
Finally, do I change properties for the size directly to button or via grid layout?
Here is the code for a new window.

Use star sizing (ratios) to size your grid's rows etc. Like , 2, 4* etc. This will make the rows and columns keep the same ratios, no matter what size the window is, like this:
<RowDefinition Height="*" />
<RowDefinition Height="2* /> //this will be 2x the previous row's height
Style the buttons for consistent width/height/other properties etc.
<Style TargetType="Button" x:Name="SomeButtonStyle">
<Setter Property="Width" Value="90" />
</Style>
then , for each button you want the same height/width/whatever property:
<Button Style="{StaticResource SomeButtonStyle}" />
This will keep you from putting a width, height or font etc. in EVERY button you made, and makes it much faster to change the value in one place, instead of every button.
I have a webbrowser in my page, with other controls, I simply just want to scroll the entire page, instead of only scrolling the webbrowser. how can I do this?
my code:
<ScrollViewer >
<!--LayoutRoot is the root grid where all page content is placed-->
<Grid x:Name="LayoutRoot" Background="White">
<Grid.Resources>
<convertstring:htmlconverter x:Name="htmlconv"/>
<convertstring:DateTimeToStringConverter x:Name="datetimestringconverter"/>
</Grid.Resources>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="200"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Source="/Images/smallerheading.png"
Margin="0,0,10,0"
Grid.Column="1"/>
<TextBlock Text="Stuff"
Foreground="Black"
FontSize="45"
Margin="15,5,0,0"
/>
<Image Grid.Row="1" Grid.ColumnSpan="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
x:Name="img"/>
<TextBlock Grid.Row="2"
x:Name="txtTitle"
TextWrapping="Wrap"
Grid.ColumnSpan="2"
FontSize="30"
Foreground="Black" />
<StackPanel Grid.Row="3">
<TextBlock Grid.Column="0"
x:Name="Autho"
TextWrapping="Wrap"
Foreground="Black"/>
<TextBlock
Foreground="Black"
x:Name="txtDate"/>
</StackPanel>
<phone:WebBrowser x:Name="webbrowsercontrol"
Grid.Row="4"
Background="Transparent"
Foreground="Black"
Grid.ColumnSpan="2"
FontSize="20">
</phone:WebBrowser>
</Grid>
</ScrollViewer>
If you don't want to scroll the WebBrowser at all, you can draw a Border that is almost transparent (like #01000000).
That way, your touch movements will not be handled by the WebBrowser, but by the Border and the page will scroll instead of the WebBrowser content.
I want to be able to individually figure out which children grids are tapped as part of a larger grid. Each of the children grid are in individual columns and rows, I'm trying to do something simple where I handle individual grids being tapped through different event handlers. What am I doing wrong? I can only get the entire grid to fire an event handler when it is tapped, but what I want is the event handler "row0col0_Tapped" to be fired only when that part of the 0th row and 0th column of the outer grid is tapped.

Please set a transparent back ground for the the grid which is to be tapped.
