So I have a rather interesting question. I have a viewbox that has a few elements in it (a custom user control for an image, a canvas, a label, and a textbox). What I want is to try and have all elements scale with the viewbox, but I want the label and the textbox to have a "Max Size." I have tried using a max width and height on these controls but they seem to ignore it. If someone could take a look at my code below an slap me for what I am doing wrong that would be appreciated.
<Viewbox Name="myViewBox" Stretch="Uniform">
<!--Grid used to track mouse movements in this element for other reasons -->
<Grid Name="grdViewboxGrid" MouseMove="trackMouse">
<Canvas Name="cvsViewboxCanvas" MinWidth="270" MinHeight="270"
VerticalAlignment="Top" HorizontalAlignment="Center"
Panel.ZIndex="1" Background="Black"
MouseUp="Canvas_MouseUp"
MouseMove="Canvas_MouseMove">
<Grid>
<!--Would rather not post here for Intellectual Property reasons-->
<!-- Extension of the image control -->
<CustomImageUserControl />
<Grid>
<Grid Width="{Binding LabelWidthPercentage}"
MaxWidth="50"
Height="{Binding LabelHeightPercentage"
MaxHeight="26"
SnapsToDevicePixels="True" VerticalAlignment="Top"
HorizontalAlignment="Left" Margin="5" IsHitTestVisible="False">
<Label Name="lblViewboxLabel" HorizontalAlignment="Left"
Padding="5,5,5,0" Margin="0,5,0,0"
Style="{x:Null}"
Content="{Binding lblContent}" />
</Grid>
<Grid>
<Grid Width="{Binding TextBoxWidthPercentage}"
MaxWidth="156"
Height="{Binding TextBoxHeightPercentage}"
MaxHeight="45"
SnapsToDevicePixels="True" Vertical="Top"
HorizontalAlignment="Right" Margin="5" IsHitTestVisible="False">
<Border Style="{DynamicResource CustomBorder}" />
<Grid>
<Textbox Name="txtViewboxTextBox" Text="{Binding txtViewbox}" />
</Grid>
</Grid>
</Grid>
</Grid>
</Grid>
</Canvas>
</Grid>
</Viewbox>
If I am not including something that is needed please let me know and I will update my question. Any help would be greatly appreciated this is now day 4 on this issue sadly :-(
I am not sure why you need so many overlapping Grids, but I hope that I can answer your question nevertheless:
In order to have the label left of the text box and to assign a maximum width to each of these two controls, use a Grid with two columns and set the MaxWidth property for each column. Then, assign the label to the left column (the one with index 0) and assign the text box to the right column (index 1). The corresponding code fragment looks like this:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition MaxWidth="30"/>
<ColumnDefinition MaxWidth="156" MinWidth="30"/>
</Grid.ColumnDefinitions>
<Label Grid.Column="0" x:Name="lblViewboxLabel" HorizontalAlignment="Left" Foreground="Yellow"
Padding="5,5,5,0" Margin="0,5,0,0"
Style="{x:Null}"
Content="{Binding lblContent}" />
<TextBox Grid.Column="1" x:Name="txtViewboxTextBox" Text="{Binding txtViewbox}" Background="Orange"/>
</Grid>
I also have assigned a MinWidth to the right column; this is necessary to make sure that the text box does not completely disappear if it contains no text.

I have created a UserControl that is suppose to display some text and then present a listbox for the user to select some item.
It is supposed to strech to the height to the grid cell it is placed in. And if there are more items than can fit on screen then to display a vertical scrollbar. After much trial and error I have finally managed to get it working as expected. But only when the row height is a pixel value. If I use any partial (by partial I mean the star symbol), the grid cell's height is not contained. Since I need the app the match screen size I need the partials to work.
Putting 100 items in the listbox suddenly makes the height of the entire grid is around 11000 (which I think is everything with no contraint). Meaning there is no scrollbar. See [Screenshot] https://i.stack.imgur.com/faES9.png.
I have a similar issue with my TextBox only horizontally. It will only activate when clicking on a specific pixel since it is empty the width is only 1 pixel. I hope someone can help me point out where I am going wrong, cause since I'm having more than one issue I suspect the problem is on my end.
This is my XAML code.

I could repro your problem when I put your UserControl in a StackPanel. When it's in a Grid the ListBox shows its vertical scrollbar. So, try your UserControl in a Grid.
I think this answer will give a good explanation about Grid and StackPanel stretching behavior.
i want to auto stretching elements horizontally to grid width, so when you stretch window elements must proportionally stretched with it.
<Grid Margin="0,0,0,40" Name="TaskGrid" Visibility="Hidden">
<StackPanel Name="AmountOfSP" Visibility="Collapsed" Orientation="Horizontal" HorizontalAlignment="Stretch">
<CheckBox Name="restrRadioButton" Checked="restrCheckBox_Checked" Unchecked="restrCheckBox_Unchecked"/>
<TextBlock TextWrapping="Wrap" Text="bla-bla" />
<TextBox Name="AmountOfO" HorizontalAlignment="Stretch" MinWidth="70" Height="20" Margin="10,0,0,0"/>
</StackPanel>
</Grid>
As I've answered here you can't use a StackPanel to strech in the stacking direction, because it will always use the smallest possible size for the stacking elements (unless they have a fixed size, then it will utilize that).
Use a DockPanel or Grid instead and order the inner components appropriately to stretch to the full size.
Adding one more option along with the mentioned answer. You can also make use of UniformGrid to achieve what you want.
<Grid Margin="0,0,0,40" Name="TaskGrid">
<UniformGrid Name="AmountOfSP" Columns="3" HorizontalAlignment="Stretch">
<CheckBox x:Name="restrRadioButton"/>
<TextBlock TextWrapping="Wrap" Text="bla-bla" />
<TextBox Name="AmountOfO" HorizontalAlignment="Stretch" MinWidth="70" Height="20" Margin="10,0,0,0"/>
</UniformGrid>
</Grid>
You can replace your stackpanel with a grid similar to the one shown below;
<Grid Name="AmountOfSP" Visibility="Collapsed">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<CheckBox Name="restrRadioButton" Grid.Column="0" Checked="restrCheckBox_Checked" Unchecked="restrCheckBox_Unchecked"/>
<TextBlock Grid.Column="1" TextWrapping="Wrap" Text="bla-bla" />
<TextBox Grid.Column="2" Name="AmountOfO" HorizontalAlignment="Stretch" MinWidth="70" Height="20" Margin="10,0,0,0"/>
<Grid>
You can play around with widths of your different controls by changing the columnDefinition widths e.g.
<ColumnDefinition Width="Auto"/>
As it stands all three of your columns will have the same width and will expand to fill the control it occupies.
You cannot use as stack panel in this way because it literally just gets it's width/height by "stacking" (adding) the widths/heights of the controls it contains.
You may find work-arounds using the stack panel but it is much easier just to use a different control meant to do the job you are after.
I have a Grid which has a TextBox inside a ScrollViewer:
<Grid DockPanel.Dock="Top">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<ScrollViewer>
<StackPanel Height="271" Width="258">
<Label FontSize="15" Margin="10"> Suggestions </Label>
<Expander x:Name="expander" Margin="10" />
</StackPanel>
</ScrollViewer>
<GridSplitter Grid.Column="0" Width="5" />
<ScrollViewer Grid.Column="1">
<TextBox x:Name="textBox" AcceptsReturn="True"
AcceptsTab="True" FontSize="15"
VerticalScrollBarVisibility="Visible"
HorizontalScrollBarVisibility="Visible"
TextWrapping="WrapWithOverflow" Language="en-US"
SpellCheck.IsEnabled="True"/>
</ScrollViewer>
</Grid>
Even if I set HorizontalScrollBarVisibility to Visible, the horizontal scroll bar is not visible, and when I type some text that goes beyond the TextBox's width, I can't scroll:
Looking at the implementation of the TextBox: http://referencesource.microsoft.com/#PresentationFramework/src/Framework/System/Windows/Controls/TextBox.cs#1473
it seems that this is the normal behavior: the horizontal scrollbar is not visible when TextWrapping is WrapWithOverflow.
Based on that, the only possible way to show the horizontal scrollbar of the TextBox is to set the TextWrapping to NoWrap.
A workarount to what (I think that) you want to achieve with the outer ScrollViewer might be:
<ScrollViewer Grid.Column="1" HorizontalScrollBarVisibility="Visible">
<TextBox x:Name="textBox" AcceptsReturn="True"
AcceptsTab="True" FontSize="15"
VerticalScrollBarVisibility="Hidden"
HorizontalScrollBarVisibility="Hidden"
TextWrapping="WrapWithOverflow" Language="en-US"
SpellCheck.IsEnabled="True"/>
</ScrollViewer>
It appears to me that the TextBox element is not being entirely displayed. I'd bet that the scroll bar is there, you just cannot see it without re-sizing your current window or scrolling downwards in the main window.
I have a Grid that I populate with a TextBlock and another Grid, which is initially hidden. Since I have the TextBlock to respond to click events, I only want the method to be called when the user clicks on the text itself, not anywhere in the Grid. This is what my code looks like right now:
<Grid x:Name="LayoutRoot" Height="25">
<TextBlock x:Name="NewLabelButton" Text="Add New" Width="Auto" Foreground="Blue" TextDecorations="Underline" MouseLeftButtonUp="AddNew_OnClick" VerticalAlignment="Center"/>
<Grid x:Name="NewLabelPanel" Visibility="Collapsed">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBox x:Name="NameBox" TextChanged="NameBox_OnTextChanged" KeyDown="NameBox_OnKeyDown" Grid.Column="0"/>
<Button x:Name="OKButton" Content="OK" Click="OKButton_OnClick" IsEnabled="False" Margin="2,0,0,0" Grid.Column="1"/>
<Button x:Name="CancelButton" Content="Cancel" Click="CancelButton_OnClick" Margin="2,0,0,0" Grid.Column="2"/>
</Grid>
</Grid>
Which results in the TextBlock spanning the whole width of the Grid, making it clickable from essentially anywhere in the Grid. What I want is for it to only be as wide as it needs to be to display the text (which could vary, so I can't use a static width).
Using a StackPanel instead of a Grid resolves the TextBlock width issue, but then the child Grid doesn't expand to fill the entire StackPanel, which it needs to.
Encapsulating the TextBlock in a StackPanel works, but I'm wondering if there is a better (and more efficient) way of doing it.
<Grid x:Name="LayoutRoot" Height="25">
<StackPanel Orientation="Horizontal">
<TextBlock x:Name="NewLabelButton" Text="Add New" Foreground="Blue" TextDecorations="Underline" MouseLeftButtonUp="AddNew_OnClick" VerticalAlignment="Center"/>
</StackPanel>
<Grid x:Name="NewLabelPanel" Visibility="Collapsed">
So my question is this: Is there a better way to do this than with my little StackPanel hack, or is that the only way? Thanks!
Try setting the HorizontalAlignment of the TextBlock to the left of the grid.
<TextBlock x:Name="NewLabelButton" HorizontalAlignment="Left" Text="Add New" Width="Auto" Foreground="Blue" TextDecorations="Underline" MouseLeftButtonUp="AddNew_OnClick" VerticalAlignment="Center"/>
I cant figure out what I am doing wrong I have a grid with 2 columns and 3 rows. In the left column I have a textblock and textbox and a listbox which is all good.
The right column gets a little more complicated where I have a tabcontrol to start. Then my TabItem and inside that I have my Main Grid and then inside that I have 2 grids. Which are grdDetailsTop and then grdDetailsBottom.
grdDetailsTop has 3 columns where the left will be an image with a Border the middle should be Member Code: 'TextBox' and under that should be Family Code: 'TextBox' and then finally under that I would like to place Balance: 'TextBox'
The way I tried it was, I have grdDetailsTop Grid with 3 columns in the first column I placed a groupbox and inside that I have a stackpanel.
Second Column is where I am having trouble I placed a Stackpanel with the orientation Horizontal and grid.Column="1" but my textblocks are going into the 3rd column without me telling them too. Sorry for the bad explanation but the code is posted hopefully you can help. Also the reason for my different Panels is so I can place a border around each column of the grdDetailsTop.
Thanks

You're missing the VerticalAlignment = "Top" on that TextBlock, and therefore, it is defaulting to Stretch which will center the text in the available vertical space. If you set that property, you'll see that it moves back up to be in line with the other TextBoxes in the same StackPanel.
It isn't actually moving that TextBox into the next column, rather, you've defined a fixed width of the column it is in (in this case, column 1 with a width of 200). But the contents of that column (the StackPanel are more than 200 units wide, so they push over into the next grid column. To keep all the TextBoxes in column 1, you'll either need to widen the column so they can fit, shrink the size of the TextBoxes or set the width Auto so it will automatically size itself to its contents. If you look at it, you're taking up 175 units with TextBlocks 2 and 3, leaving only 25 units for the rest of the TextBlocks in that StackPanel. There's just not enough space.
<StackPanel Margin="5" MaxWidth="200" Orientation="Horizontal" Grid.Column="1">
<TextBlock VerticalAlignment="Top" Margin="5" Height="25">Member Code:</TextBlock>
<TextBlock VerticalAlignment="Top" Margin="5" Width="75" Height="25"></TextBlock>
<TextBlock VerticalAlignment="Top" Margin="5" Height="25" Width="100">Family Code:</TextBlock>
... other text boxes ...
</StackPanel>
This will fix the vertical layout issue, but not the Horizontal layout issue. That requires changes to the grid column sizing or the size of the contents.
Per your comment below, I believe you're looking for the WrapPanel which will automatically wrap items to the next line (horizontal or vertical) when it runs out of space.
<WrapPanel Margin="5" MaxWidth="200" Orientation="Horizontal" Grid.Column="1">
<TextBlock VerticalAlignment="Top" Margin="5" Height="25">Member Code:</TextBlock>
<TextBlock VerticalAlignment="Top" Margin="5" Width="75" Height="25"></TextBlock>
<TextBlock VerticalAlignment="Top" Margin="5" Height="25" Width="100">Family Code:</TextBlock>
... other text boxes ...
</WrapPanel>
This layout certainly looks nicer. But - I don't know your specific requirements, however rather than using a WrapPanel with fixed margins and sizes, I would recommend using a Grid with ColumnDefinitions and RowDefinitions to organize items in this type of layout. The Grid offers a much greater level of flexibility and allows for items to automatically resize based on system font sizes, a user resizing your view and other factors out of your control. If you are setting fixed heights/widths, you lose that flexibility. Again, I don't know you're requirements, so perhaps this is the best solution for you, but under most circumstances, I'd highly recommend a Grid instead.
