How to use Gird in Windows Apps?
I want to create a Login form. I have used grid and used but the Rows are not aligned properly, How can I do that?
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="67*"/>
<ColumnDefinition Width="293*"/>
</Grid.ColumnDefinitions>
<StackPanel>
<TextBlock Text="Name" Height="32" Margin="0,0,0.333,0" ></TextBlock>
<TextBlock Text="Last Name" Height="30" Margin="0,0,0.333,0" ></TextBlock>
<TextBlock Text="Address"></TextBlock>
</StackPanel>
<StackPanel Grid.Column="1">
<TextBox></TextBox>
<TextBox></TextBox>
<TextBox></TextBox>
</StackPanel>
</Grid>
You should define the rows and columns in Grid.
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="67*"/>
<ColumnDefinition Width="293*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="45"></RowDefinition>
<RowDefinition Height="45"></RowDefinition>
<RowDefinition Height="45"></RowDefinition>
</Grid.RowDefinitions>
<TextBlock Text="Name" Grid.Column="0" Grid.Row="0" VerticalAlignment="Center"></TextBlock>
<TextBlock Text="Last Name" Grid.Column="0" Grid.Row="1" VerticalAlignment="Center"></TextBlock>
<TextBlock Text="Address" Grid.Column="0" Grid.Row="2" VerticalAlignment="Center"></TextBlock>
<TextBox Grid.Column="1" Grid.Row="0" Height="30"></TextBox>
<TextBox Grid.Column="1" Grid.Row="1" Height="30"></TextBox>
<TextBox Grid.Column="1" Grid.Row="2" Height="30"></TextBox>
</Grid>

I'm learning the below Xamarin code, I would like to make each image fulfills its cell. I already tried VerticalOptions="FillAndExpand".
But it doesn't work. How to solve it?
<Grid x:Name="initialpagelayout" VerticalOptions="StartAndExpand" >
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Image VerticalOptions="FillAndExpand" BackgroundColor="Red" Grid.Row="0" Grid.Column="0" x:Name="MyIcon01"></Image>
<Image BackgroundColor="Blue" Grid.Row="0" Grid.Column="1" x:Name="MyIcon02"></Image>

<Image Grid.Row="3" Grid.Column="1" x:Name="MyIcon11"></Image>
<Image Grid.Row="3" Grid.Column="2" x:Name="MyIcon12"></Image>
</Grid>
UPDATE1
I added Aspect="Fill" into each <Image>, and I get the below:
It works well but I notice there is a blank space above the first row, but I don't have any placeholder there,

I am using auto complete textbox from windows phone toolkit.I need the list of suggestions below my textbox but it shows up above the text box .How do I make the suggestions appear below the text box..Here is my XAML.
<Grid Margin="0,336,0,189" x:Name="editrow" Visibility="Visible">
<Grid.RowDefinitions>
<RowDefinition Height="auto"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>

<toolkit:AutoCompleteBox.ItemTemplate>
<DataTemplate>
<StackPanel Background="Gray" Orientation="Horizontal">
<TextBlock Text="{Binding }"/>
</StackPanel>
</DataTemplate>
</toolkit:AutoCompleteBox.ItemTemplate>
</toolkit:AutoCompleteBox>
<TextBox x:Name="rowquantity" Foreground="White" Background="#53000000" BorderThickness="0" Grid.Column="1" Grid.Row="0" InputScope="Number"></TextBox>
<toolkit:ListPicker Grid.Row="0" x:Name="units" Foreground="White" BorderThickness="0" Background="#53000000" Grid.Column="2" ExpansionMode="FullScreenOnly" Margin="12,5,0,14" >
<toolkit:ListPicker.FullModeItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0 0 0 0">
<TextBlock Text="{Binding}"
FontSize="32" LineHeight="1"/>
</StackPanel>
</DataTemplate>
</toolkit:ListPicker.FullModeItemTemplate>
</toolkit:ListPicker>
<Button Content="Add" BorderBrush="#53000000" Foreground="#53000000" Grid.Column="1" Grid.ColumnSpan="2" Grid.Row="1" HorizontalAlignment="Right" VerticalAlignment="Top" Height="74" Click="Button_Click" Margin="0,0,3,0" Width="158"/>
</Grid>
The location of the popup is determined based on the available size. If there's more space above the AutoCompleteTextBox, it will pop up. You can see this in the popuphelper.cs source file where the code arranges the popup.
There really isn't an option to override the behavior.
So I have a listbox with a template in which I bind an ObservableCollection of objects called "TotalDebits".
I have two way to delete the items:
One by one through a context menu
By range through a delete button and by fetching the checked objects.
This works:
private void Delete_Click(object sender, RoutedEventArgs e)
{
DeleteDebit((DirectDebit)(((MenuItem)sender).DataContext));
}
private void DeleteDebit(DirectDebit ddb)
{
TotalDebits.Remove(ddb);
}
private void delete_Click(object sender, EventArgs e)
{
DeleteDebitList();
}
private void DeleteDebitList()
{
try
{
foreach (var ddb in TotalDebits.ToList())
if (ddb.IsChecked)
TotalDebits.Remove(ddb);
}
catch
{
}
}
In both case, the items are properly deleted, the problem is, in the second case, the keyboard is showing up right after the items are deleted, for absolutely no reason.. Of course I can hide it right after by focusing on the list but it looks ugly and I wish I could find a way to prevent this issue from happening.
Edit:
You'll find hereunder the xaml of the page:

Problem solved!
Anyway, I just figured out the problem. I did a .Trim() on the values and surprisingly they can be wrapped. Thanks and sorry for all the trouble. =)
I am doing some data binding to my textblock in a grid.
However, some of the texts are not showing fully.
I tried the Text Wrapping and setting a maximum width to my textblock. But none of them worked.
EDIT : Hi again. I noticed that when I changed the text of the textblock manually via codes like
txtDesc.Text = "This is a job for Stackers. If you like stacking, please contact me.
The text wrapping actually works. So somehow the databind result text can't be wrap?
The XAML code for my textblock.
<TextBlock Name="Description" Grid.Row="4" Text="{Binding Description}" FontSize=" {StaticResource PhoneFontSizeSmall}" Height="auto" Width="220" Margin="0,0,0,0" TextWrapping="Wrap" HorizontalAlignment="Left" VerticalAlignment="Top" MaxWidth="220"></TextBlock>
Any help here?

It comes from poor / over-complicated layout architecture and the way your objects are positioning each other. Might try something like this for your DataTemplate
<DataTemplate>
<Grid ShowGridLines="True">
<Grid.RowDefinitions>
<RowDefinition Height="50"/>
<RowDefinition Height="50"/>
<RowDefinition Height="30"/>
<RowDefinition Height="30"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="60"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<!-- Don't worry, you already had your 450 Width set on the parent -->
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Name="Date" Text="{Binding Date}" FontSize="{StaticResource PhoneFontSizeLarge}"/>
<TextBlock Name="Creator" Grid.Row="1" Text="{Binding CreatorID}" FontSize="{StaticResource PhoneFontSizeLarge}"/>
<TextBlock Name="Type" Grid.Row="2" Text="{Binding Type}" FontSize="{StaticResource PhoneFontSizeSmall}"/>
<TextBlock Name="Amount" Grid.Row="3" Text="{Binding Amount}" FontSize="{StaticResource PhoneFontSizeSmall}"/>
<TextBlock Name="Description" Grid.Row="4" Text="{Binding Description}" FontSize="{StaticResource PhoneFontSizeSmall}" TextWrapping="Wrap"/>
<Button Name="btn1" Click="btn_Click" Grid.Row="5" Grid.Column="1" Content="Apply" Height="70" Width="140" Margin="5,0"/>
</Grid>
</DataTemplate>
Also for the sake of cleaner xaml, remember things like Margin="0", Grid.Column="0", HorizontalAlignment="Left" etc. are default dependency properties, so no need to set them to each individual object. Even in the case you need to, you can apply them as Setters to the TargetType in the parent Object.Resources and avoid setting them to each individual object. Another tip would be, don't rely on a bunch of obfuscated random Margins etc to create your layout. It's best to do it right the first time instead of hunting down discrepancies between a bunch of inter-dependent little "fixes"
I didn't test it, but should work fine unless you got something else somewhere pushing stuff around. Hope this helps.
Can you disable horizontal scrolling in your listbox control?
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
Use VerticalAlignment="Stretch" instead of VerticalAlignment="Top". This way the textblock will stretch to the height of the row.
