I am new to C# and WPF development, and I am working on a program that encodes and decodes bitmaps. I have the following XAML code and its expected output:
<Page x:Class="Thompson_EncodeDecode.BeforeDecoding"

Title="BeforeDecoding">
<Grid Margin="10,0,10,10">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Border Grid.Column="0" Height="35" Padding="5" Background="White">
<Label VerticalAlignment="Center" Foreground="Black">Before Encoding</Label>
</Border>
<Border Grid.Column="1" Height="35" Padding="5" Background="White">
<Label VerticalAlignment="Center" Foreground="Black"> After Encoding</Label>
</Border>
</Grid>
What I am trying to do is add an image onto both columns of the grid so that I can show that the images are the same, but also below that show what the encoded and decoded message within the bitmap is to show that the encoding is actually working. I am unsure how to add an image to the column without either making the image the background for the grid, and also maintaining the Grid integrity.
Also some extra pointers on how to have the input data shown on the bottom right of the grid column would be helpful too. Most of the Googling I have been doing regarding this particular program has confused me, and I am wondering if there is a standard way of approaching it.
You can achieve this in many ways, one of the way is as follows
<Grid Background="Gray">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<!-- U can move this duplicate code into an usercontrol to reuse-->
<Grid Grid.Column="0">
<Grid.RowDefinitions>
<!--Header-->
<RowDefinition Height="1*"/>
<!--Body-->
<RowDefinition Height="8*"/>
<!--Footer-->
<RowDefinition Height="1*"/>
</Grid.RowDefinitions>
<Label Content="Header" Grid.Row="0"/>
<Image Grid.Row="1"/>
<Label Content="footer" Grid.Row="2" HorizontalContentAlignment="Right"/>
</Grid>
<Grid Grid.Column="1">

</Grid.RowDefinitions>
<Label Content="Header" Grid.Row="0"/>
<Image Grid.Row="1"/>
<Label Content="footer" Grid.Row="2" HorizontalContentAlignment="Right"/>
</Grid>

I have a user control with a text box and 2 buttons below it. I want the text box to stretch vertically when the parent window stretches vertically but nothing happens. Another problem is that the buttons appear bunched up under the text box when the user control is put into a window. But when I view the user control while not in a window the buttons are separated by 1 grid row. How can I get this to work properly so the text box increases in size when the parent window is stretched vertically and also have the buttons at the bottom stay away from the text box?
Here is the xaml code for the window that uses the user control:

Thanks in advance.
You can greatly simplify your markup by using just grids.
You seem to have misunderstood the way the * gridmeasure works.
I think the markup below does what you're trying to achieve.
When you put most controls in a grid(cell) they will expand to take up all the space available. That's what you want here so all you want is grids and cells.
The * is not an abstracted measure of the actual height in the way you are using it.
You had a control spanning two rows.
I simplified that by making one of the rows 2* height.
If you wanted two controls in the right column next to it then you would of course probably want 5 rows. But you don't have that.

Henk Holterman's comment to remove the StackPanel around the text solves the problem. The textbox would not vertically stretch in or outside a user control while inside a StackPanel. I had to remove the StackPanel around the textbox in the user control as well as in the window that used the user control. Below are the code updates for a working sample:
The User Control with StackPanel removed:

I want to ask,if this is possible,in my case I have 2 columns and 2 rows,every part contains a Grid like this:

</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>

</Grid>
<Grid Grid.Column="1" Grid.Row="0">
</Grid>
<Grid Grid.Column="1" Grid.Row="1">
</Grid>
</Grid>
I want when I hover on one Grid,the other Grids and their components will be disabled,I have search for a property like "IsEnabled="False"" for Grids,but I didn't found any resources on the net
I have used "IsHitTestVisible="False"" property but it's not the result what I want,
so any help please,to achieve what I want
thanks for Help
I defined the following DialogWindow:

<Button Content="Cancel" Grid.Column="1" Click="Cancel_Button_Click"></Button>
</Grid>
</Grid>
</ui:DialogWindow>
The layout basically consists of three rows. The first row has a title label, the bottom row two buttons and in the middle, I want to have a list of UI elements that I add dynamically in the code to the Grid there. Since I don't know in advance how many items that are, I want to display them in a ScrollViewer.
I can see that ScrollViewer is drawn, but the problem is, the ScrollViewer overlaps with the title label and is also somewhat clumsy. When I remove the ScrollViewer, this is not the case. So what am I doing wrong?
Just change the Grid.Row=1 for the ScrollViewer. It will work. Refer below code.
<Grid Name="root">
<Grid.RowDefinitions>
<RowDefinition Height="60px"></RowDefinition>
<RowDefinition Height="510px"></RowDefinition>
<RowDefinition Height="30px"></RowDefinition>
</Grid.RowDefinitions>
<Label Grid.ColumnSpan="2" Grid.Row="0" Grid.Column="0" Name="TitleLabel" Content="Please rate the difficulty you perceived while working with each of the following code elements (1 = ''very easy'' / 6 = ''very difficult'')"></Label>
<ScrollViewer MinHeight="510px" Grid.ColumnSpan="2" Grid.Row="1" Grid.Column="1">
<Grid Name="ElementContainer">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="150"></ColumnDefinition>
</Grid.ColumnDefinitions>
</Grid>
</ScrollViewer>
<Grid Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Button Content="OK" Grid.Column="0" Click="OK_Button_Click"></Button>
<Button Content="Cancel" Grid.Column="1" Click="Cancel_Button_Click"></Button>
</Grid>
</Grid>
Hello and thanks for your help in advance. I have two panels, one with a series of the buttons and a Telerik RadTreeView boxed by a border, and on the right another border encompassing a grid and some other controls. Everything is sized properly as I resize the page etc however for some reason there are about 10 pixels being cut-off and cannot think of why. If it was a page container issue it would affect the border on the right side of the page. So I'm thinking it must have something to do with the RadTreeView or WrapPanel I'm using. (Boiled-down code is right after the image below)

Didn't have time nor the inclination to look into the underlying template/styling for either the RadTreeView or the WrapPanel. I was able to fix the issue and maintain the layout by simply putting the RadTreeView in it's own row and leaving just the buttons and other controls in the wrap panel. Suppose it is simpler this way anyway.
Definitely must be a bug or compatibility issue with these two controls that will probably go unsolved.
I'd like to create a custom WPF accordion-like control without using WPF toolkit... After some searching it seems like the best approach would be to use an Expander... so I wanted to just see if I could get some sort of basic functionality like getting a row to expand upward to show some content when it is expanded and then to have it collapse and hide that content. It seems like it should be pretty straight-forward but my expander never expands. Here's my basic example:
<Grid Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="30"></RowDefinition>
<RowDefinition Height="Auto"></RowDefinition>
<RowDefinition Height="1*"></RowDefinition>
<RowDefinition Height="24"></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="215"></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<Expander Grid.Row="3" Grid.ColumnSpan="2" Header="More Options" ExpandDirection="Down" Background="Red" IsExpanded="False">
<StackPanel Height="300">
<CheckBox Margin="4" Content="Option 1" />
<CheckBox Margin="4" Content="Option 2" />
<CheckBox Margin="4" Content="Option 3" />
</StackPanel>
</Expander>
</Grid>
Update your RowDefinitions. Currently, the Row that the Expander is in is hard-coded to have a Height of 24. Make it Auto.
<Grid.RowDefinitions>
<RowDefinition Height="30"></RowDefinition>
<RowDefinition Height="Auto"></RowDefinition>
<RowDefinition Height="1*"></RowDefinition>
<RowDefinition Height="Auto"></RowDefinition>
</Grid.RowDefinitions>
