On a ViewModel a property of "OperationStepInstance" is commanding a huge process if asking for its value.
My question is, if there is a way to not ask for its value while in XAML the element is hidden or collapsed.
By default, even if it is collapsed, a Dependency property is always asked for its value.

I have a data template that is:
<DataTemplate x:Key="CalDescButton">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock
Grid.Row="0"
Grid.RowSpan="2"
Grid.Column="0"
Grid.ColumnSpan="2"
Style="{StaticResource LargeIconStyle}"
Text="" />
<TextBlock
Grid.Row="0"
Grid.Column="1"
Foreground="Transparent"
Style="{StaticResource MediumIconStyle}"
Text="" />
<TextBlock
Grid.Row="1"
Grid.Column="1"
Foreground="Transparent"
Style="{StaticResource MediumIconStyle}"
Text="" />
<TextBlock
Grid.Row="0"
Grid.Column="1"
Foreground="Transparent"
Style="{StaticResource MediumIconStyle}"
Text="" />
<TextBlock
Grid.Row="1"
Grid.Column="0"
Foreground="Transparent"
Style="{StaticResource MediumIconStyle}"
Text="" />
<TextBlock
Grid.Row="1"
Grid.RowSpan="2"
Grid.Column="0"
Margin="0,-6,0,0"
Foreground="Aqua"
Style="{StaticResource XSmallIconStyle}"
Text="" />
</Grid>
</DataTemplate>
Then I have other 6 where the only thing that changes is the Text Char code.
Those templates are applied to buttons:
<ToggleButton
Command="{Binding CmdSetSorting, Mode=OneWay}"
CommandParameter="CalAsc"
ContentTemplate="{StaticResource CalDescButton}" />
The question is: can I pass a variable to the template and use it in the Text="" instead of having 6 different templates just for that?
How can I do it?
Just to be clear I'd like to have something like:
<DataTemplate x:Key="IconButton">
and then:
ContentTemplate="{StaticResource IconButton ()}" />
set Content property of Button:
<ToggleButton
Command="{Binding CmdSetSorting, Mode=OneWay}"
CommandParameter="CalAsc"
Content=""
ContentTemplate="{StaticResource CalDescButton}" />
it should become DataContext of root element in DataTemplate (because it is ContentTemplate) and will be accessible by Binding:
<TextBlock
Grid.Row="0"
Grid.RowSpan="2"
Grid.Column="0"
Grid.ColumnSpan="2"
Style="{StaticResource LargeIconStyle}"
Text="{Binding}" />
This is my sample code ,Please help me to achieve both goals simultaneouslyImage
On click toggle button collapse and visible column and vertical split button.
In the below fig. First add toggle button and First column contain two column .
It contains second sub column is collapse or disable based on toggle button click.

The final column of the below grid view is not displaying in the center vertically, though the first image is and they use the same lookup method to find the image source (A resource dictionary object locator class I have). The final image (CurrencyImg) has the bottom of the image aligned with the middle of the row, so it stretches out of view upwards and doesn't fill the lower half of the row. Confused!

I have a StackPanel, but the following line :
<TextBlock Grid.Row="1" Grid.Column="0" Text="{Binding Notes}" TextWrapping="Wrap" />
is not Wrapping the Text.

The StackPanel Orientation is set to 'Vertical' but the TextBlock is not inheriting it.
Where am I going wrong?
Your problem is using the StackPanel that allows its children to fill in all the available space - the StackPanel stretches accordingly to the size of its content. Try removing the StackPanel and keep just the Grid - this way you will limit the size of its children to the available space used by the Grid.
If that isn't enough in the layout you've built, try setting a MaxWidth on the TextBox that needs wrapping.
Now the source of your problem was also the fact that your TextBox was inserted in the first Column of the Grid that had an infinite size (Width="Auto"). Thus, setting the Grid.Column="7" to the TextBox did the trick you wanted (wrapping text). Here's the revised code:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="5" />
<ColumnDefinition Width="15" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<DockPanel Grid.Row="0" Grid.Column="0">
<TextBlock FontWeight="Bold" Padding="0,0,5,0" Text="{Binding Path=Id, StringFormat='#\{0\}'}" />
<TextBlock FontWeight="Bold" Padding="0,0,5,0" Text="{Binding Path=Name}" />
</DockPanel>
<TextBlock Grid.Row="0" Grid.Column="4" FontWeight="Bold" Text="{Binding Path=Time, StringFormat={}{0:HH:mm}}" />
<Image
Grid.Row="0"
Grid.Column="6"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Source="{Binding Path=Image, Mode=OneWay, Converter={StaticResource ImageConverter}}" />
<TextBlock Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="7" Text="{Binding Notes}" TextWrapping="Wrap" />
<Image
Grid.Row="1"
Grid.Column="4"
HorizontalAlignment="Center"
VerticalAlignment="Top"
Source="{Binding Path=Picture, Mode=OneWay, Converter={StaticResource PictureConverter}}" />

If I have two elements in a stackpanel:
<StackPanel Margin="2,2,2,2" Orientation="Horizontal">
<TextBlock Grid.Column="0" Text="{Binding Name}" />
<TextBox Grid.Column="1" Text="{Binding Age}"/>
</StackPanel>
How can I set them with the width equally 50%,50%?
To answer your comment
<Grid>
<!-- Define Columns -->
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Name}" />
<TextBox Grid.Column="1" Text="{Binding Age}"/>
</Grid>
use UnformGrid with columns 2 or Grid with 2 columns
<UniformGrid Columns="2">
<TextBox></TextBox>
<TextBox></TextBox>
</UniformGrid>
or
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0"
Text="{Binding Name}" />
<TextBox Grid.Column="1"
Text="{Binding Age}" />
</Grid>
