I am using a GridView to display some products.
When I set the DataTemplate I use Width and Height with static values and define some rows for the data I want to display.
<Grid Width="97" Height="180"">
<Grid.RowDefinitions>
<RowDefinition Height="80"/>
<RowDefinition Height="20"/>
<RowDefinition Height="*"/>
The first row is for a 80x80 image and the second for the price.So far, so good.
Then I face the problem that even if the data shown (with the name of the product) in the last row, with a TextBlock, is just one line, the GridViewItem takes the value defined from the height property.
Is there a way for the height to adjust on TextBlock's Text. I tried setting Height to Auto, not including at all for the Grid and the TextBlock but then the text is not appearing whole on the screen.
I have a feeling what you want is the text to wrap around. You can achieve this by setting the text to wrap, like in the code demonstrated below:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="80"/>
<RowDefinition Height="20"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid Grid.Row="0" Background="Red" />
<Grid Grid.Row="1" Background="Blue" />
<TextBlock Grid.Row="2" TextWrapping="Wrap" Text="This is some text which will not fall off the edge because it is set to wrap around, and will continue filling down until the end of the screen because the grid is set to auto" />
</Grid>

I'm developing an application using WPF by c#.
I have 2 frames next to each other. The above will not change and just updated(like Facebook toolbar).
The bottom frame will change by clicking on some buttons. (it is something like masterpage in ASP).
I don't want to set a height and width for window or for frames. The problem is when I make the window full screen there is a space between two frames.
However none of the vertical/horizontal alignment stretch does not work.
<window>
<Frame VerticalAlignment="Top" Background="Crimson" />
<Frame VerticalAlignment="Bottom" Background="Black"
/>
</Window>
I want to create something like the this site as you see. the notify section and the main page.
EDIT:
i can put them next to each other just by set the height, but when i make full the window the heights stay and the yellow space becomes appear, so i want to find a way to put them Exactly next to each other in every window size.
As Mitch noted in the comments, you could place the two frames in a grid instead, and let the grid size the items.
<Window>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Frame Grid.Row="0" Background="Crimson" />
<Frame Grid.Row="1" Background="Black" />
</Grid>
</Window>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Frame Grid.Row="0" Background="Crimson" />
<Frame Grid.Row="1" Background="Black" />
</Grid>
I have a little problem with AdControl.
AdControl shows ads and my PubCenter counts everything, but images are too little like this (down):
<ads:AdControl Grid.Row="2"
AutoRefreshIntervalInSeconds="60"
ApplicationId="myid"
AdUnitId="myunitid"
HorizontalAlignment="Center"
Height="80"
IsAutoRefreshEnabled="True"
VerticalAlignment="Top"
Width="400"/>
So you said you have your layout in a 3 row Grid like this;
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="80"/>
<RowDefinition Height="*"/>
<RowDefinition Height="80"/>
</Grid.RowDefinitions>
</Grid>
...and you want your adverts to consume that "80" height of the 3rd row but still keep their resolution. So you could do something like this instead;
<ViewBox Grid.Row="2" Stretch="UniformToFill">
<ads:AdControl Grid.Row="2"
AutoRefreshIntervalInSeconds="60"
ApplicationId="myid"
AdUnitId="myunitid"
IsAutoRefreshEnabled="True"/>
</ViewBox>
This way it should take whatever the contents of the AdControl are and use them to fill the space you've provided (in this case, an "80" height you set in your Row Height, and whatever width of the device. With the Stretch="UniformToFill" set it should retain the resolution while filling that space and keep the same aspect ratio as whatever is provided to it.
Hope this helps, cheers.
Critical problem here. In my case i assemble the below code for my application. Unfortunately, it creates the bigger problem in layout. Even we put RowDefinitions with Auto, it does not consider the RowHeight and goes underneath to the Bottom of the Windows Phone emulator.
<Grid>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid Grid.Row="0" x:Name="firstGrid" Tap="FirstGrid_OnTap"/>
<Grid Grid.Row="1" Visibility="Collapsed">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Button Content="A"/>
<Button Grid.Column="1" Content="B"/>
</Grid>
</Grid>
</Grid>
On loading of the page, it fills the firstGrid with the ImageBrush. Hence whenever user taps on the firstGrid, It will just insert one more row to the Grid by enabling the visibility of the second grid. This second grid will have couple of buttons. I astonished when i see the second grid because it hides in the bottom of the emulator. Even my hundred of different attempts , i am not able dig into the main problem which actually it has. Any help is much appreciated.
As per my understanding u need to make this change in code first row should be auto and second *.
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
So I'm pretty new to WPF and I'm having trouble with the layout of my Window. Currently I have a WPF application with a Grid defined as such:
<Grid.RowDefinitions>
<RowDefinition Height="23" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
In the very top row, spanning two columns, I have a Menu. In the second row I have some Labels in the first column and an Image and a WindowsFormsHost in the second, finally, in the third row I have a graphing control in the second column. By default, I set the size of the Image and WFH to 570 x 413. Now, I'd like for both the Image and WFH to expand when my Window is resized such that they maintain the same relative (to the Window) size. (I actually would like the same to happen to my graphing control as well, but I can probably figure that one out if I can get the others. I cannot for the life of me figure out what setting I need to turn on/off or what I might need to bind or whatever in order to make this happen. Any help is greatly appreciated!
Thanks!
Have you tried:
<RowDefinition Height="*" />
Make sure to assign your Grid.Row within your image or control, but do not sign the controls height/width properties. The control should autosize with expansion.
Update
Did a quick test to make sure this works.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="23"/>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Label Grid.Row="0" Content="Example"/>
<Image Grid.Row="1" Source="c:\Example.jpg"/>
<Label Grid.Row="2" Content="Example2"/>
</Grid>
The image expands with the application based on the image's proportions. It does expand, but it keeps it's dimensions along with the full image in view. If you were to change the rowdefinition from ***** to Auto, you will notice that the image will expand, but it will expand past your view. Meaning you will not always see the full image.
I would suggest making a simple application like above, and playing with constraints to figure out what each does.
You need to show more information in your description, because all of the properties of the Grid and of the Image, etc. will factor into the layout.
However, you probably want to look at the HorizontalAlignment and VerticalAlignment properties of your Grid and of your Image, as well as the Stretch property of the Image. Also, you don't want to specify a fixed size for the image (you can specify a MinWidth and a MinHeight if you want them to be a certain size when starting up).
Here's a quick example that shows a grid filling a window, with a scaling image.
<Grid HorizontalAlignment="Stretch"
VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="23" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Label Grid.Column="0" Grid.Row="0" Grid.ColumnSpan="2" Content="First Row" />
<Label Grid.Column="0" Grid.Row="1" Content="Column 0, Row 1" />
<Image Grid.Column="1" Grid.Row="1"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Source="Resources\ExamplePicture.png"
Stretch="Uniform" />
I have a simple xaml control with the following Grid Row definition:
<Grid.RowDefinitions>
<RowDefinition Height="15*" />
<RowDefinition Height="60*" />
<RowDefinition Height="20*" />
<RowDefinition Height="20*" />
<RowDefinition Height="15*" />
</Grid.RowDefinitions>
Rows 1-3 each hold a text block which may or may not have text in it. In the code behind I want to minimise the RowDefinition if there is no text. Essentially I have the following in my code behind:
if(textblock.Text != ""){
grid.RowDefinitions[elementRow].Height = new GridLength(20, GridUnitType.Star);
}
else{
grid.RowDefinitions[elementRow].Height = new GridLength(0, GridUnitType.Star);
}
I want rows 0 and 4 to stay as they are defined in the xaml. Unfortunatly this does not work even though there is text in the text block on row 2 nothing is displayed.
Am I doing something wrong.
Any help is appreciated,
James
Don't use the star notation, use Auto for your RowDefinitions. If the TextBlock.Text is empty, set the Visibility of the TextBlock to Visibility.Collapsed. The grid row will then automatically shrink to nothing.
This is not the answer to your question, just some info.
The * in the Height (or width for columns) means that the row (or column) width Height="*" (or Width="*") will take up the rest of the space. So if you have a grid with 4 rows in a grid with Height="100", if you do this:
<Grid.RowDefinitions>
<RowDefinition Height="10" />
<RowDefinition Height="10" />
<RowDefinition Height="10" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
The row width Height="*" will be 70 DIUs (device independent units).
Adding a number before the asterisk (Height="2*") only works if there are more than one rows using the asterisk, the number before the asterisk indicates how much more space will that specific row take (2* = twice as much, 3* three times as much, so on...). I. E.:
<Grid.RowDefinitions>
<RowDefinition Height="10" />
<RowDefinition Height="10" />
<RowDefinition Height="2*" /> <!-- this row will be twice as tall as the one below -->
<RowDefinition Height="*" />
</Grid.RowDefinitions>
Here the 3rd row will have a height of 54 DIUs (twice as much as the 4th row which has a height of 26 DIUs approx.), both heights sum 80, which is the rest of the space of the grid (10 + 10 + 26 + 54 = 100, the grid height).
BTW, I agree with Charlie's answer.
You can put your items inside a UniformGrid with Columns="1" And make the TextBox Visibility to collapsed when you get emptry text.
<UniformGrid Columns="1">
<TextBlock Text="AAAA" Visibility="Collapsed" Grid.Row="0"/>
<TextBlock Text="BBBBB" Grid.Row="1"/>
<TextBlock Text="CCCCC" Grid.Row="2"/>
<TextBlock Text="DDDDD" Grid.Row="3"/>
<TextBlock Text="EEEE" Grid.Row="4"/>
</UniformGrid>
