I have a border1 with full screen and it's Background is #011627. A Grid splits into four part, one of them have border2 and it's Background is #0b192a.
<Border x:Name="border1" Background="#011627"/>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="1" Text="Test" Foreground="White" FontSize="30"/>
<Border x:Name="border2" Background="#0b192a"/>
</Grid>
Now I want to set Grid's Opacity to 0.1 and influence text's Opacity, and don't influence border2's Background.
But it doesn't meet my expectation.
<Border x:Name="border1" Background="#011627"/>
<Grid Opacity="0.1">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="1" Text="Test" Foreground="White" FontSize="30"/>
<Border x:Name="border2" Background="#0b192a"/>
</Grid>
Could it happen? Thanks!
UIElement.Opacity is by definition applied to all child elements of the (sub)tree, where the root is the element that defines the value.
If you want the to set Opacity exclusively to a specific element, you have to set it locally/by Style on this very element:
<Grid>
<TextBlock Opacity="0.1" Text="Test" />
<Border x:Name="border2" />
</Grid>

How to access a nested grid element with Grid.Column and Grid.Row? Normally, Grid.Column="1" Grid.Row="0" is the way to go. But I dont know how to access a nested one? for example: Column 0, Nested Column 3, Row 1.
I have added a picture of the layout structure:
Grid Layout
<Button Grid.Column="1" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Top" Width="87" Height="23" Text="btn" BorderThickness="1,1,0,1" />
Nested grid:
<Grid x:Name="LayoutRoot" Background="#FFA3A3A3" Height="540" Width="952" HorizontalAlignment="Left" VerticalAlignment="Top">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="10"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="10"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="10"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="10"/>
</Grid.RowDefinitions>
<Grid Grid.Column="1" Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="140*"/>
<ColumnDefinition Width="346*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="52*"/>
<RowDefinition Height="220.5*"/>
</Grid.RowDefinitions>
</Grid>
</Grid>
<Grid Grid.Column="1" Grid.Row="2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="40*"/>
<ColumnDefinition Width="120*"/>
<ColumnDefinition Width="146*"/>
<ColumnDefinition Width="146*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
</Grid>
Some code...
<Button Grid.Column="1" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Top" Width="87" Height="23" Text="btn" BorderThickness="1,1,0,1" />
</Grid>
you can/need not access a nested grid.
Grid.Column/Row always means the parent grid.
<Grid x:Name="Grid1">
<Grid x:Name="Grid2" Grid.Row="0", Grid.Columns="0">
<TextBlock Grid.Row="0", Grid.Columns="0"> TextBlock in Grid2[0,0]</TextBlock>
</Grid>
<TextBlock Grid.Row="1", Grid.Columns="0"> TextBlock in Grid1[1,0]</TextBlock>
</Grid>
The nested Grid2 is in [0,0] of Grid1
I want to get a structure like this:
So i tried this:
<!-- Canvas -->
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="4*"/>
</Grid.ColumnDefinitions>
<!--Toolbox & poperties -->
<Grid Grid.Column="0">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<StackPanel Grid.Row="0">
<Button Content="sdf"/>
</StackPanel>
<StackPanel Grid.Row="1">
<Button Content="sdf"/>
</StackPanel>
</Grid>
</Grid>
But I couldn't get the half of the height using grid. What else I could do?
You can try the following markup and use Grid.RowSpan to extend StackPanel into two rows
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="4*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Button Grid.Column="0" Grid.Row="0" Content="sdf"/>
<Button Grid.Column="0" Grid.Row="1" Content="sdf"/>
<StackPanel Grid.Column="1" Grid.Row="0" Grid.RowSpan="2"/>
</Grid>
the code below is a small snippet of a big wpf Window I am using in my Project. It produces the linked wpf Window.
I am wondering why my last grid column is so wide. I am expecting that the width of the last column depends on the width of the button, because the column width is set to "Auto".
If I remove the columnspan of the StackPanel the column width will be correct but then the CheckBoxes are not aligned to right side.
I hope you have understood my problem. My aim is, that the last column is as small as possible, the checkboxes are at the right side and the rest stays at it is.
Because this snippet is part of a bigger wpf window I cannot remove any grid rows or columns.
Thank you very much for your help.
Best regards.

I'm developing a resolution independent application in WPF. I am using mahapps metro controls in my application. I have a grid which is divided into rows and columns in * and 4 TextBoxes are occupying specific rows and columns in that grid.
The problem is that the TextBox is not occupying the row as in the bottom border of
Textbox is not visible but when I change style to x:Null the problem disappears. Is this a problem specific to metro TextBox?. I tried VerticalAlignment = "Stretch" but this does'nt help.
Also the bottom part is visible in higher resolution like 1440 X 900 but not in 1366 X 768. What am I missing?

I want to have a childGrid in second column of parentGrid (in childGrid I want to have two columns: first for label, second for textbox)
How can I do Something like that? I tried the following code:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Height="*"/>
<ColumnDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.ColumnDefinitions>
<Grid Grid.Column=1>
<Grid.ColumnDefinitions>
<ColumnDefinition Height="*"/>
<ColumnDefinition Height="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
</Grid>
</Grid>
Based on your code, just fixed up a little:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid Grid.Column="1">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
</Grid>
</Grid>
Note that ColumnDefinition don't have a Height - they have a Width. You also need to define the ColumnDefinitions and RowDefinitions separately - you have them mixed together in your outer grid. I removed the RowDefinitions from the outer grid because you don't appear to be using them. Your inner grid has two columns and four rows.
You might find this useful. Try pasting this into a page using Kaxaml and playing around with the various parameters of the objects in the outer Grid. I find using Kaxaml for prototyping and experimenting with XAML layouts indispensable.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>

When I'm composing grids in XAML, I group things together by type, not by where
they live in the grid. This turns out to make a lot of maintenance tasks
easier.
Also, since Grid.Row and Grid.Column default to 0, a lot of people (and tools)
omit them if that's their value. Not me. It lets me quickly check to make
sure that content is where I think it is, just by looking at how it's organized
in the XAML.
-->
<TextBlock Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" Background="Lavender" Padding="10" HorizontalAlignment="Stretch">Here's the first row of the outer grid.</TextBlock>
<TextBlock Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="2" Background="Lavender" Padding="10" HorizontalAlignment="Stretch">Here's the third row of the outer grid.</TextBlock>
<TextBlock Grid.Row="1" Grid.Column="0" Background="AliceBlue" Padding="10">Here's the first column of the second row.</TextBlock>
<Grid Grid.Row="1" Grid.Column="1">
<Grid.ColumnDefinitions>
<!--
This part's pretty important. Setting up the SharedSizeGroups for these
two columns keeps the labels and text boxes neatly arranged irrespective of
their length.
-->
<ColumnDefinition SharedSizeGroup="Label"/>
<ColumnDefinition SharedSizeGroup="TextBox"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Label Grid.Row="0" Grid.Column="0">First label</Label>
<Label Grid.Row="1" Grid.Column="0">Second label</Label>
<Label Grid.Row="2" Grid.Column="0">Third label, containing unusually long content</Label>
<TextBox Grid.Row="0" Grid.Column="1">First text box, containing unusually long content</TextBox>
<TextBox Grid.Row="1" Grid.Column="1">Second text box</TextBox>
<TextBox Grid.Row="2" Grid.Column="1">Third text box</TextBox>
</Grid>
</Grid>
It might come a little confusing how to put controls in sub grids. Here is an example.
We have 3 * 3 cell grid. And then center cell is further divided in 3 rows where each row has a button.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid Grid.Row="1" Grid.Column="1">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Button Grid.Row="0" Content="Button1"/>
<Button Grid.Row="1" Content="Button2"/>
<Button Grid.Row="2" Content="Button3"/>
</Grid>
</Grid>

Phenevo, I've done XAML UI design extensively this year. Try this out, you can easily migrate the code to either a Window or a UserControl. I color-coded the grids and panels so that you could affirm their layout in real time -- blow away the background parameters when you're satisfied.
