xaml textbox vs textblock

The WPF TextBlock control is a lightweight text editor control for displaying and formattting small amount of text flow content. The Name attribute represents the name of the control, which is a unique identifier of a control. The Foreground property sets the foreground color of contents.

This control does not have a Background property. The code snippet in Listing 1 creates a TextBlock control and sets the name, height, width, foreground and content of a TextBlock control. Unlike a TextBox control, the TextBlock does not have a default border around it. As you can see from Figure 1, by default the TextBlock is place in the center of the page. We can place a TextBlock control where we want by using the Margin, VerticalAlignment and HorizontalAlignment attributes that sets the margin, vertical alignment, and horizontal alignment of a control.

The code snippet in Listing 2 sets the position of the TextBlock control in the left top corner of the page. The code listed in Listing 3 creates a TextBlock control programmatically. First, it creates a TextBlock object and sets its width, height, contents and foreground and later the TextBlock is added to the LayoutRoot.

The code snippet in Listing 4 sets the font properties of a TextBlock. The FontSource property allows loading custom fonts dynamically.

The following code snippet sets the FontSource property. The TextWrapping property sets the wrap of no wrap text. The following code snippet sets the wrapping text option.

A text can be aligned left, center, or right. The Padding property sets the space between a boundary and the text that can be applied to all sides or a selected side of the boundary. The padding spacing is based on left, right, top, and bottom. If you specify only a single value, the padding will be applied to all four sides and if you specify two values, it will be applied to LeftTop and BottomRight sides.

The Inlines property represents the collection of inline text within a TextBlock control. A Run object represents an inline text and can be treated as its own text control and have its foreground and font related properties. Listing 6 sets the Inlines property of the TextBlock and sets different fonts and foreground colors.

The TextDecorations property represents the text decorations that are applied to the content of a TextBlock. WPF supports only underline text decoration.Have any question? Feel Free To Post Below:.

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.

I hope this post can be helpful to avoid some pitfalls and to be proficient on developing with it.

The lack of Margin property. Label, Button, etc. Each time you need to define a margin to separate two adjacent elements, you need to wrap each of them inside a ContentView the simplest layout descendant to set the padding property. The default value of Spacing property. This is simple to describe and use, once you know it: when using StackLayout or Grid bear in mind that their respective spacing properties Spacing for StackLayout and both RowSpacing and ColumnSpacing for Grid have a default value of six.

This is a bit annoying and I would prefer to have a predefined value of zero. If you agree, please vote for it. If we try to use the same XAML on Xamarin Forms, we need to do minor name adjustments and explicitly define zero spacing:. This is a strange behavior, because the containing grid do extend to the full available horizontal length we know it because the red background of the grid fill all the spacebut the two inner grids do not.

In this case, the containing grid do take the entire available place but set the horizontal width of the column to the width of his largest children. The good news are that this will change on Xamarin Forms 1. Until then beware of the details!

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. 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. 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.
