I'm using Prism. I have a ContextControl region, and a view associated with that region. Within the view is a TabControl. The controls are displaying data with no problem, but the controls within the TabControl are not displaying any data. I have tried setting the DataContext and ItemsSource(for the TabControl) , without success. The data to be displayed is from the SelectedSession class.

I was getting the data from a DataGrid. Once I defined the columns for the data it started working.

I got a page, in which there's a frame (that contains 2 input forms, that can be switched to with 2 buttons above the form) and a listView which contains the inputs from the user. When the User finishes the input, I want to pass an Object from the frame to the parent page.
I tried getting the Parent with the Parent property, but the parent property is for some reason null. I also tried to search for a solution on the web, but I wasn't able to find anything helpful. Does anyone of you know my problem can be solved?
Parent Page:

I found out how this can be solved:
You just give a reference of the parent page to the page in the frame through the constructor, like this:
private void changeToForm1(object sender, RoutedEventArgs e)
{
inputFrame.Content = new Form1(this);
}
Now, you can just save the reference into a variable and call methods to transfer the data to the parent page.
I am using Syncfusion's SfDataGrid instead of standard one, but this question is more about XAML, not the control itself, I think.
So, I have a window with DataGrid. If there is for example 60 records, then the window gets really tall. I want the window not to change its size at all. And really don't know why it's happening.
This is my XAML:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Grid Grid.Column="0">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<StackPanel Margin="10,0,10,0" Grid.Row="0" DataContext="{Binding Info}">
<TextBlock Text="Amount:"/>
<sf:CurrencyTextBox Value="{Binding Amount}" Margin="0,0,0,10"/>
<!-- some other controls -->
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Grid.Row="0" Style="{StaticResource LeftLabel}"
Text="Count:"/>
<sf:UpDown Grid.Column="1" Grid.Row="0" Margin="0,0,0,5"
Value="{Binding Count}"/>
<TextBlock Grid.Column="0" Grid.Row="1" Style="{StaticResource LeftLabel}"
Text="Year count:"/>
<sf:UpDown Grid.Column="1" Grid.Row="1"
Value="{Binding YearCount}"/>
</Grid>
</StackPanel>
<Button Grid.Row="1" HorizontalAlignment="Right" VerticalAlignment="Bottom" Margin="0,10,10,5"
Content="Simulate >>"
Command="{Binding SimulateCommand}"/>
</Grid>
<!-- This is right part of the window with datagrid -->
<DockPanel Grid.Column="1">
<WrapPanel DockPanel.Dock="Top">
<TextBlock Margin="10" Text="Total amount:" />
<TextBlock Text="{Binding TotalAmount"/>
</WrapPanel>
<!-- and the datagrid -->
<sf:SfDataGrid AutoGenerateColumns="False"
AllowDeleting="False"
AllowEditing="False"
IsReadOnly="False"
AllowGrouping="False"
AllowFiltering="False"
ItemsSource="{Binding History}">
<sf:SfDataGrid.Columns>
<sf:GridDateTimeColumn DisplayBinding="{Binding Date}" MappingName="PaymentDay" HeaderText="Date"/>
<sf:GridCurrencyColumn DisplayBinding="{Binding Amount}" MappingName="PayAmount" HeaderText="Amount"/>
</sf:SfDataGrid.Columns>
</sf:SfDataGrid>
</DockPanel>
</Grid>
So what is wrong with it?
I've encountered this problem during development, the problem the compiler gives, is that an object reference is not set, So it should be some kind of null pointer

This is the code where it gives the error (line of ). How can I solve this problem since I initialized this view model?
If you have correct ViewModel, the compiler error may be caused by Visual Studio's bug, happened in VS 2015,VS2013, etc.So the solution is :
Try to delete .suo file and then restart Visual Studio.
I have a grid that contains one ItemsControl with another grid. I would like to align the two splitters in the two grids. I have implement Grid.SharedSizeScope but this option shared only the column of the grid is located. Do you have any suggestions?
This is my xaml code.

ok, what if you will actually take out the itemscontrol and move it outside the grid and then put everything into dockpanel ?

C# code in wpf
Visual childVisual = (Visual)VisualTreeHelper.GetChild(LayoutRoot,0);
With above code i can get the First child of the grid(LayoutRoot).But i want to get grid child by it's rows or columns. What should i do for that.
Thanks in Advance.
Filter the Grid.Children based on what Grid.GetRow and GetColumn returns for every child.
e.g.
var itemsInFirstRow = LayoutRoot.Children
.Cast<UIElement>()
.Where(i => Grid.GetRow(i) == 0);
