In WPF, I'm trying to create a button with four labels at each corner. It would look like a dice (die?) with text in the corners instead of dots.
This code doesn't work:
<Button HorizontalAlignment="Stretch" Background="Red" Height="100" >
<Grid ShowGridLines="True">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Label Grid.Row="0" Grid.Column="0" Content="TopLeft"/>
<Label Grid.Row="0" Grid.Column="1" Content="TopRight" HorizontalContentAlignment="Right" VerticalContentAlignment="Bottom" HorizontalAlignment="Right" VerticalAlignment="Bottom" />
<Label Grid.Row="1" Grid.Column="0" Content="BottomLeft"/>
<Label Grid.Row="1" Grid.Column="1" Content="BottomRight" HorizontalContentAlignment="Right" VerticalContentAlignment="Bottom" HorizontalAlignment="Right" VerticalAlignment="Bottom" />
</Grid>
</Button>
It mashes the text into the center of the grid instead of moving it to the corners. It seems like the grid is not taking up all the space in the button.
Any help appreciated. Thank you.
Set the VerticalContentAlignment and HorizontalContentAlignment for the Button to Stretch.
<Button HorizontalAlignment="Stretch" Background="Red" Height="100" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch">
<Grid ShowGridLines="True" VerticalAlignment="Stretch" >
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Label Grid.Row="0" Grid.Column="0" Content="TopLeft"/>
<Label Grid.Row="0" Grid.Column="1" Content="TopRight" HorizontalContentAlignment="Right" VerticalContentAlignment="Bottom" HorizontalAlignment="Right" VerticalAlignment="Bottom" />
<Label Grid.Row="1" Grid.Column="0" Content="BottomLeft" VerticalContentAlignment="Bottom" />
<Label Grid.Row="1" Grid.Column="1" Content="BottomRight" HorizontalContentAlignment="Right" VerticalContentAlignment="Bottom" HorizontalAlignment="Right" VerticalAlignment="Bottom" />
</Grid>
</Button>

I've never really worked with WPF before so this might be a newb question but is there a way to change the background color of a column of a WPF grid?
I want to change column 0's background color from the code.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition x:Name="Banner" Width="25" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Border Grid.Row="0" Grid.Column="0" Background="Gainsboro" />
<Border Grid.Row="1" Grid.Column="0" Background="Gainsboro" />
<Border Grid.Row="2" Grid.Column="0" Background="Gainsboro" />
<Border Grid.Row="3" Grid.Column="0" Background="Gainsboro" />
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Label x:Name="titleLabel"
Grid.Row="1" Grid.Column="1" HorizontalAlignment="Left" VerticalAlignment="Center" Margin="3"
FontWeight="Bold"
Content="Title" >
</Label>
<Label x:Name="msgLabel"
Grid.Row="2" Grid.Column="1" HorizontalAlignment="Left" VerticalAlignment="Center" Margin="3"
Content="Title" >
</Label>
</Grid>
You can add one more border and place it in first column (note RowSpan):
<Border x:Name="firstColumn"
Grid.Column="0"
Grid.Row="0"
Grid.RowSpan="4"
Background="Transparent"/>
When need to change background from code, just do
firstColumn.Background = Brushes.Red;
I'm new in WPF and I try to creat specific UserControl to display data for a single product. I used Grid inside UserControl. So I create 5 columns and 3 rows. I want ot make 4 columns fixed (image, green-clored, blue-colored and column with controls) and last column (orange-colored) to fill all availabel space. Here my XAML and few screenshots:
<Grid Margin="0,0,0,5" Background="#FFDCD9D9" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="80" />
<ColumnDefinition Width="70" />
<ColumnDefinition Width="70" />
<ColumnDefinition Width="70" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Image Grid.Column="0" Grid.Row="0" Grid.RowSpan="4" Source="{Binding ItemThumbnailUrl}" Stretch="None" HorizontalAlignment="Right" Margin="5,0" />
<StackPanel Grid.Column="1" Grid.Row="0" Grid.ColumnSpan="4" Background="#FFDA6F6F">
<Label BorderThickness="0" Content="dsgsdgsgsgsdgsdg sd " FontSize="13.333" FontWeight="Bold" HorizontalAlignment="Left" />
</StackPanel>
<StackPanel Grid.Column="1" Grid.Row="1" Orientation="Horizontal" Background="#FF517823" HorizontalAlignment="Left" Width="70">
<Label Content="{Binding ItemPrice}" HorizontalAlignment="Left" FontSize="9.333" Width="45" />
<Label Content="грн." HorizontalAlignment="Left" FontSize="9.333" Width="25"/>
</StackPanel>
<StackPanel Grid.Column="2" Grid.Row="1" Orientation="Horizontal" Background="#FF214299" HorizontalAlignment="Left" Width="70">
<Label Content="{Binding Quantity}" HorizontalAlignment="Left" FontSize="9.333" Width="45" />
<Label Content="шт." HorizontalAlignment="Left" FontSize="9.333" Width="25"/>
</StackPanel>
<StackPanel Grid.Column="1" Grid.Row="2" Orientation="Horizontal" Background="#FF88B91E" HorizontalAlignment="Left" Width="70">
<Label Content="1С" HorizontalAlignment="Right" FontSize="9.333" Foreground="#FF8B8888" Width="45"/>
<Label Content="грн." HorizontalAlignment="Right" FontSize="9.333" Foreground="#FF8B8888" Width="25"/>
</StackPanel>
<StackPanel Grid.Column="2" Grid.Row="2" Orientation="Horizontal" Background="#FF228CBD" HorizontalAlignment="Left" Width="70">
<Label Content="1С" HorizontalAlignment="Right" FontSize="9.333" Foreground="#FF8B8888" Width="45"/>
<Label Content="шт." HorizontalAlignment="Right" FontSize="9.333" Foreground="#FF8B8888" Width="25"/>
</StackPanel>
<CheckBox Grid.Column="3" Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center"/>
<Button Grid.Column="3" Grid.Row="2" Background="{x:Null}" Content="Редакт." Foreground="#FF444343" Width="50" HorizontalAlignment="Center" VerticalAlignment="Center" />
<Label Grid.Column="4" Grid.RowSpan="2" Grid.Row="1" Background="#FFE08212" HorizontalContentAlignment="Stretch" />
</Grid>
If I have "Title" text (in red-colored cell) less than sum of 3 my fixed columns, everything is OK, but if a text larger I have problems with some paddings between columns (please see pictures)
So how can I resolve this problem?
I could reproduce your issue in a variety of cases when a Grid is used in a DataTemplate. I removed the StackPanel and used a TextBlock, then a a TextBlock hosted in a separate Grid, but all with the same result. I guess something is going wrong when WPF is determining the required size. I have often occurred this kind of strange behaviour in Grids (when part of an ItemTemplate). If you need a quick workaround then this should do the trick
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="80" MaxWidth="80" />
<ColumnDefinition MinWidth="70" MaxWidth="70" />
<ColumnDefinition MinWidth="70" MaxWidth="70" />
<ColumnDefinition MinWidth="70" MaxWidth="70" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
I'm design a simple login window and i'm very wondering about this.
Well, this is my XAML code
<Grid ShowGridLines="False">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<DockPanel Grid.Row="0">
<Label x:Name="label_ID" Height="30"/>
<TextBox x:Name="textBox_ID" Height="20" TabIndex="0">
<TextBox.Margin>
<Thickness Right="5"/>
</TextBox.Margin>
</TextBox>
</DockPanel>
<DockPanel Grid.Row="1">
<Label x:Name="label_PW" Height="30"/>
<PasswordBox x:Name="textBox_PW" Height="20" TabIndex="1">
<PasswordBox.Margin>
<Thickness Right="5"/>
</PasswordBox.Margin>
</PasswordBox>
</DockPanel>
<DockPanel Grid.Row="2">
<Label x:Name="label_IP" Height="30"/>
<TextBox x:Name="textBox_IP" Height="20" UndoLimit="2">
<TextBox.Margin>
<Thickness Right="5"/>
</TextBox.Margin>
</TextBox>
</DockPanel>
</Grid>
label_ID's string is ID
label_PW's string is Password
label_IP's string is 'IP'
And the output is like this:
https://www.dropbox.com/s/k23ft06layp0sl4/1.PNG?dl=0
The password text box only short then other.
(I want to short another text boxes to.)
How can i fix location of text boxes?
Thanks.
I think your DockPanels are not really needed, instead you could use two columns in the Grid:
<Grid ShowGridLines="False">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Label Grid.Row="0" Grid.Column="0" x:Name="label_ID" Height="30"/>
<TextBox Grid.Row="0" Grid.Column="1" x:Name="textBox_ID" Height="20" TabIndex="0" Margin="5"/>
<Label Grid.Row="1" Grid.Column="0" x:Name="label_PW" Height="30"/>
<PasswordBox Grid.Row="1" Grid.Column="1" x:Name="textBox_PW" Height="20" TabIndex="1" Margin="5"/>
<Label Grid.Row="2" Grid.Column="0" x:Name="label_IP" Height="30"/>
<TextBox Grid.Row="2" Grid.Column="1" x:Name="textBox_IP" Height="20" UndoLimit="2" Margin="5"/>
</Grid>
Setting the first column's width to Auto ensures that the text will be visible, the second column will take the rest of the space (*).
It produces an output like this (with some test strings added by me):
Simplest way I could think of is
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="30" />
<RowDefinition Height="30" />
<RowDefinition Height="30" />
</Grid.RowDefinitions>
<Label Name="lblID" Content="ID:" HorizontalAlignment="Right" VerticalAlignment="Center" Width="Auto" Margin="5,2,5,2" />
<TextBox Name="txtID" HorizontalAlignment="Left" VerticalAlignment="Center" Grid.Column="1" Grid.Row="0" Margin="5,2,0,2" Width="250" Height="25" />
<Label Name="lblPwd" Content="Password:" HorizontalAlignment="Right" VerticalAlignment="Center" Width="Auto" Grid.Column="0" Grid.Row="1" Margin="5,2,5,2" />
<PasswordBox Name="pwdBx" HorizontalAlignment="Left" VerticalAlignment="Center" Grid.Column="1" Grid.Row="1" Margin="5,2,0,2" Width="250" Height="25" />
<Label Name="lblIP" Content="IP:" HorizontalAlignment="Right" VerticalAlignment="Center" Width="Auto" Grid.Column="0" Grid.Row="2" Margin="5,2,5,2" />
<TextBox Name="txtIP" HorizontalAlignment="Left" VerticalAlignment="Center" Grid.Column="1" Grid.Row="2" Margin="5,2,0,2" Width="250" Height="25" />
</Grid>
Right now I can only think of using the margin property as in:
<UIElement Margin="left, top, right, bottom" />
<Menu Name="EgMenu"
Margin="20,20,0,20" />
The margin property will help you position and size your UI elements in an easiser way thatt youy can visualise just looking at the text. But why not use WYSIWYG and, refine by editting XAML later.
I have the following code:
<Popup Name="enterNamePopup" Width="250" Height="200" AllowsTransparency="True" Placement="Center" IsOpen="true">
<Grid Background="Aquamarine">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="120" />
<ColumnDefinition Width="120" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="7"/>
<RowDefinition Height="20" />
<RowDefinition Height="30" />
</Grid.RowDefinitions>
<TextBlock Name="PleaseEnterName" Foreground="Black" Grid.Row="1" Text="Save as..." Grid.ColumnSpan="2" />
<TextBox Name="ProjectNameTextBox" Visibility="Visible" Grid.Row="2" Grid.ColumnSpan="2" />
<Button Name="SaveProjectButton" Content="Save Project" Grid.Row="3" Grid.Column="1"/>
<Button Name="CancelButton" Content="Cancel" Grid.Row="3" Grid.Column="2" />
</Grid>
</Popup>
Can anyone tell me why it looks like this
When i want to have something like this
You only have three RowDefinitions. They will be numbered 0, 1 and 2. Any row number higher than 2 will go into row 2.
I have a DockPanel with two Grids (DockPanel.Dock="Right/Left"). In the left i have a TreeView and in the right i have some TextBoxes. If i resize my window the panels resize proportinal.
My problem is, if i write long text in a TextBox the TextBox enlarge and hide my left DockPanel instead of a break the text.
I have set minwidth of the left DockPanel to '300' and set TextWrapping in the TextBoxes to 'wrap' but nothing helps.
Source:
<Grid Background="#FF58ACFC" Name="main">
<DockPanel>
<Grid DockPanel.Dock="Right" Margin="0,0,5,0">
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="200" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="26"/>
<RowDefinition Height="26"/>
<RowDefinition Height="26"/>
<RowDefinition Height="60" />

<Grid DockPanel.Dock="Left" Margin="5,0,0,0">

</Grid.ColumnDefinitions>
<Label Content="Kategorie" Grid.Column="0"/>
<Button Grid.Column="1" BorderThickness="0" HorizontalAlignment="Right">

<TreeView HorizontalAlignment="Stretch" VerticalAlignment="Stretch"Padding="0,0,15,0" />
</DockPanel>
</Grid>
<Grid DockPanel.Dock="Right">
<DockPanel LastChildFill="True">
<Grid DockPanel.Dock="Top" Height="26">

<Label Content="Lernkarten" Grid.Column="0"/>
<Button Grid.Column="1" Width="26" Click="ButtonAddItem_Click">
</Grid>
<ListView />
</DockPanel>
</Grid>
</DockPanel>
</Grid>
</DockPanel>
</Grid>
That's pretty much why Dockpanels are useless :-)
I suggest using Grid..
