Can set font size, font type, font styling, to wrap and to range left, right or centred. Can have opacity set and have Pixel Shaders applied. TextBlock: Used for displaying text more focused typographically. Can contain text set to different colors, fonts and sizes. The line height can also be increased from the default setting to give more space between each line of text.
WPF TextBlock Example
Text inside a TextBlock cannot be made selectable by the user. TextBox: Used for displaying text more focused for content input or when content is needed to be made selectable by the user. Can only be set to one colour, one font size, one font type etc.
Have fixed Line Spacing. Can also be set to a fixed height and width but also have scrollbars switched on to allow content to expand.

Not sure if TextBlock is lighter than TextBox. Hello Mike, sure - in terms of memory usage textbox is way heavier: s In case the proof image at some future point is gone. Your example shows a 14x difference in memory usage. Code used GC. GetTotalMemory true before and after doing a stack.
How do I assign vertical center alignment to the text inside a TextBlock? I found TextAlignment property but it is for horizontal text alignment. How do I do it for vertical text alignment? The best way to do this that I've found is to put the textblock inside a border, so the border does the alignment for you. Note: This is functionally equivalent to using a grid, it just depends how you want the controls to fit in with the rest of your layout as to which one is more suitable.
While Orion Edwards Answer works for any situation, it may be a pain to add the border and set the properties of the border every time you want to do this. Another quick way is to set the padding of the text block:. If you can do without the text wrappingI think that replacing the TextBlock with a Label is the most succinct way to do this.
Otherwise follow one of the other valid answers. TextBlock doesn't support vertical alignment of its content. If you must use TextBlock then you have to align it with respect to its parent. However if you can use Label instead and they do have very similar functionality then you can position the text content:. The Label will stretch to fill its bounds by default, meaning the label's text will be centred.
This could be because the TextBlock is wrapped in a grid, but then so is practically everything in wpf. Just for giggles, give this XAML a whirl. It isn't perfect as it is not an 'alignment' but it allows you to adjust text alignment within a paragraph.
You can see my blog post. You can set custom height of Textblock from codebehind.La sposa di campagna di william wycherley
For setting custom height you need to set it inside in a border or stackpanel. I found I had to do it slightly different. My problem was that if I changed the font size, the text would move up in the TextBox instead of stay on the bottom with the rest of TextBoxes on the line.
Here's how:. To expand on the answer provided by Orion Edwards, this is how you would do fully from code-behind no styles set. Basically create a custom class that inherits from Border which has its Child set to a TextBox. The example below assumes that you only want a single line and that the border is a child of a Canvas. Also assumes you would need to adjust the MaxLength property of the TextBox based on the width of the Border. The example below also sets the cursor of the Border to mimic a Textbox by setting it to the type 'IBeam'.
A margin of '3' is set so that the TextBox isn't absolutely aligned to the left of the border.However, I am getting an error in Blend when I added the property.Camin t4 iasi
Aligning the TextBlock within the layout of the page is done with the HorizontalAlignment and VerticalAlignment properties. For the TextBox, I can set the property, but clearly, it has no effect. I hope you want to get all alphabets of a word one below other, when you say you want text block to be vertical aligned. I guess there is not such equivalent in SL. The Silverlight edition of this does not show the HorizontalContentAlignment. As for the TextBox, yes it doesn't seem to have any effect. I'm guessing the template of the TextBox control is overriding the HorizontalContentAlignment property.

Make a suggestion.Here: The appearance attributes we set are not important. They just make the block look different. Type "MouseEnter" and then have Visual Studio add the event handler. Windows; using System. Controls; using System. Change Text to Enter when mouse enters. Change Text to Leave when mouse leaves. Several attributes in the XAML were set that influence appearance. On the TextBlock element, we have both attributes that indicate event handlers and ones that describe the visual appearance.
FontFamily: This indicates the font, such as "Georgia" or "Verdana". A string value here is sufficient.
XAML - TextBlock
Background: This is the background color of the block. AliceBlue is a light blue shade. The background is the "back color" of the control. Padding: The padding of the TextBlock in pixels.
The pixel padding expands the colored block of the control.
Labelled TextBox In WPF
Width: This indicates the number of pixels the TextBlock is wide. If the block is too small, the text is not fully shown. The MouseEnter event on a TextBlock can be used to create a hover effect.
In the example, we change the Text value to "Enter" when the mouse enters the rectangle. The MouseLeave event will also be needed.
Note: We can get the originating object for the MouseEnter event by casting the sender object to a TextBlock. This event handler can "erase" the changes made by Enter.As is so often is the case, StackOverflow has provided another interesting question that reminded me of an issue I encounter from time to time. The question is about how to have a sequence of labelled textboxes, such that everything is nicely aligned.
This is clearly quite a verbose solution and there must be a better way if we are going to be doing this sort of thing a lot. And we are.
Another annoyance with this approach is the need to renumber everything if we want to insert a row or column. It would be nice to have something more akin to HTML tables.1963-up riviera
Before we try and solve the problem, it might be a good idea to think in the abstract of what we would like to be able to write in an ideal world. It would be difficult to get more concise than that and still retain the expressiveness of what we want to do.UWP: Text in Textblock Textbox zur letzten Zeile scrollen
So how are we going to go about this? IsSharedSizeScope set to True. Here we need to introduce some Dependency Properties.
This allows the user of the LabelledTextBox to bind to Label and Text and for the control to use them too. Note that we have to set the DataContext of the Grid to the control, so that we can bind to our own Label and Text properties but we leave the top-level DataContext of the control in the broader context, so that other things can bind to our Label and Text properties too. Finally, we need to create a container control that has shared size scope.
We can doing this by creating a subclass of StackPanel and then setting Grid. IsSharedSizeScope to True. This gives us the ability to put it all together in the following way that is very similar to our initial desired solution with the exception of references to the namespace path of the controls. One could, of course, go a step further and have a Command property that allows a button to be shown, e.
And even have the button hidden if no command is bound to it. Posted by Mark Withall: Return to the main page Other me on the Internet.Here is another request that a friend of mine asked me recently.

It's just a control composed by a TextBox and a TextBlock and, when user double clic on the Textblock, I simple change the visibility of the Textbox: all the rest is just for the style Oups, I wasn't observant enaough. Yep, your solutions looks good.
I'am just too much into ASP.
Hello, Where do you route the MouseDoubleClick event onto the control? Any idea why this would work. Note: works fine if you place the control in a ItemsControl. A hybrid approach like this one would be good to keep the performance of a textblock until it's clear that the user needs editing.
You'd have to lazy load the textbox though. May try it. I just think it shows how clunky WPF is. So much fuss, so many lines of code for achieving something that basic. Quite alarming, giving that one of the main purposes of the framework is to help us in developing sophisticated UI quickly.

Comments have been disabled for this content.A TextBlock provides a lightweight control for displaying small amounts of read-only text. Gets or sets a value that indicates whether text selection is enabled in the TextBlock, either through user action or calling selection-related API.
We recommend you to execute the above example code and experiment with some other properties and events. Previous Page. Next Page. Previous Page Print Page.
IsTextSelectionEnabled Gets or sets a value that indicates whether text selection is enabled in the TextBlock, either through user action or calling selection-related API. SelectionHighlightColor Gets or sets the brush used to highlight the selected text. SelectionStart Gets the starting position of the text selected in the TextBlock. TextAlignment Gets or sets a value that indicates the horizontal alignment of text content. TextTrimming Gets or sets the text trimming behavior to employ when content overflows the content area.
ContextMenuOpening Occurs when the system processes an interaction that displays a context menu. Focus Focuses the TextBlock, as if it were a conventionally focusable control.
