Collapse Grid Row In Wpf

So let’s add some custom behavior to sync the collapsed rows with their controls. Similarly, if MinHeight or MaxHeight is set on any of the rows that are collapsed, it no longer collapses the row at all. I tried to fix this by adding team organization setters for these properties in the data trigger but it did not fix it. I have created a custom WPF element extended from RowDefinition that should collapse rows in a grid when the Collapsed property of the element is set to True.

In WPF if you want to layout a typical business form like the one shown in Figure 1, most people would use a Grid control with rows and columns. While sometimes you might need the re-sizing capabilities of a Grid, you sometimes just need a fixed size. For a fixed-size form a StackPanel control can be a little ico developer easier and offers a little more flexibility. Besides Auto and star sizing, you can also specify widths and heights in terms of pixels. In fact, when only numbers are present, it represents that number of pixels. Instead, it’s preferable to use relative values like Auto and star sizing for layout.

Changing Grid Row Background Color In Wpf

For example, “Auto” means that the height for the row should be tall enough to accommodate all of the controls that are placed inside of it. If the tallest control is 100 pixels tall, then that’s the actual height of the row. Therefore, “Auto” means the height is relative to the controls Blockchain Development inside of the row. As @Ivan mentioned in his post, the controls that are contained by collapsed rows will still be focusable, allowing users to access them when they shouldn’t. Admittedly, it could be a pain setting the visibility for all controls by hand, especially for large XAMLs.

However, you do lose the re-sizing capabilities, so this is a tradeoff. Now, there are advantages and disadvantages to using a Grid and to using a StackPanel. A Grid is great because the text box controls will automatically re-size as the user sizes the form. However, if you have several rows and you wish to insert a row in the middle, you need to renumber each row after the new row. Sometimes the VS.NET designer will renumber them for you, but sometimes it won’t.

Wpf: Grid With Column

In this lesson I want to talk about layout, or in other words, how controls are positioned and arranged on your app’s user interface.

A StackPanel will arrange your controls in a flow from top to bottom or from left to right depending on the Orientation property you set. First, run the example using the code above, then collapse the bottom rows by checking the checkbox. Now, press the TAB key once and use the ARROW UP key to move the wpf grid row GridSplitter. As you can see, even though the splitter isn’t visible, the user can still access it. /// Apply a fixed margin to all direct children of the Panel, overriding all other margins. This property can be applied to Grid, StackPanel, WrapPanel, UniformGrid, or any other descendant of Panel.

Now, let’s layout the same form using a series of StackPanel controls. Each StackPanel for each “row” will have the Orientation set to “Horizontal”. There will also be a Style setup for each Label to set the Width property to a specific amount so each text box will be aligned correctly. The grid-row-gap property defines the size of the gap between the rows in a grid layout.

You’ll see how these are used in advanced scenarios, however I don’t believe we’ll see them used in this series. Double-click on a particular textbox to create an association between that Control’s event and an event handler. Double-clicking will automatically name the event and create a method stub for you in the code behind. One thing to note from this example is that control widths and heights are assumed to be 100% unless otherwise specified. This is why in Lesson 2 the button first occupied the entire grid, and why I had to specify I wanted the button to be 200 x 100 pixels instead.

Wpf Grid Row Sizing Issue

A flexible, easy to configure replacement for the standard WPF Grid control Download WpfAutoGrid from Nuget. c# margin padding, The Margin property defines the space around the control that keeps other controls a specified distance from the control’s borders. The Padding property defines the space in the interior of a control that keeps the control’s content a specified distance from the control’s borders. The Margin property defines the space around the control that keeps other controls a specified distance from the control’s borders.

• It’s presumed that children will want to manage the layout of their own contents.
• In this series, we’ve already “wired up” the Click event of our “Click Me” button with a method that I called an “event handler”.
• Double-clicking will automatically name the event and create a method stub for you in the code behind.
• All you need is something to cache the height of the visible row.
• In fact, I’ve grown to the point where I prefer the flexibility of the StackPanel to the rigid nature of the Grid.

• Now, let’s layout the same form using a series of StackPanel controls.

The asterisk is known as “star sizing” and means that the height of the row should take up all the rest of the height available. One very large row that contained another Grid called the “ContentPanel”. The intent of the ContentPanel was that you would add the remainder of your XAML layout code there.

The Windows Phone Runtime will pass along the sender as an input parameter. Once we cast the Object to a Button then we can access the Button’s properties, etc. First, you must make sure you’ve selected the Control you want to edit by placing your mouse cursor in that element. The name of that element software development cycles will appear in the Name field at the top letting you know the context of the settings below. In other words, any settings you make will be to the button as opposed to another control on the page. A second way to associate an event with an event handler is to use the Properties window in Visual Studio.

Of course the controls would still be accessible, allowing the user to trigger events. You should have either a MaxHeight on the collapsable row or a MinHeight on the non-collapsable row adjacent to the splitter. This to ensure the star sized row has a size when you put the splitter all wpf grid row the way up and toggle visibility. All you need is something to cache the height of the visible row. After that, you no longer need converters or to toggle visibility of contained controls. In the example below, this works perfectly when the grid splitter is over half way up the window.

In this series, we’ve already “wired up” the Click event of our “Click Me” button with a method that I called an “event handler”. When I use the term “event handler” I’m merely referring to a method that is associated with an event. I use the term “wired up” to mean that the event is tied to a particular wpf grid row event handler method. Some events events can be triggered by a user, like the Click event of a Button control. Other events happen during the lifetime of an event, like a Loaded event that occurs after the given Page or Control object has been instantiated by the Phone APIs Runtime engine.

Or, if you wish to move an existing row below or above another, you will also be doing a lot of manual renumbering. and when I try to cover the bar in manual mode it is add a margin . Visual Studio also created a method stub in the code-behind for the XAML page, in our case, the MainPage.xaml.cs. We could have hit the escape key on the keyboard when Intellisense first popped up and typed that code in by hand.

As we continue throughout this series, I’ll use multiple StackPanels to organize the various XAML controls on screen. In fact, I’ve grown to the point where I prefer the flexibility of the StackPanel to the rigid nature of the Grid. Since we’re stacking horizontally, I’ve added a StackPanel that will be positioned to the right of the Bisque colored rectangle and it will arrange items in a vertical fashion. Inside of that StackPanel I create two other StackPanels that are oriented horizontally. Thus, the intricacy continues until I have a series of rectangles that resemble something Frank Lloyd Wright would have been proud of.
