In addition, in order to prevent too frequent changes of grid sizes if user are resizing window slowly, timer is used in application. The timer is created in the constructor and starts or restarts each time one view height or view width are changed. The post is devoted to the WPF datagrid with cells that have defined fixed size but number of rows and columns is updated dynamically in order to fill all available space. For example, such grid could be used in games at infinite 2D field or implementation of cellular automaton.

• As number of rows and columns are integers, real size of cells on the view could not equal to values of cell width and height.
• In the following post this issue is solved with asynchronous method that updates cell array.
• For example, such a grid could be used in chess or checkers games for 8×8 field.
• As you can see from the resulting screenshot, or if you run the sample yourself, the details are now shown below the selected row.
• As you can see from the code listing, it’s mostly about expanding the details template into using a panel, which in turn can host more panels and/or

  controls.

Once rows and columns are added to Grid, you can add any

contents to Grid cells by using SetRow and SetColumn methods. SetRow and

SetColumn methods take first parameter as the control name and second parameter

as row number and column number respectively. The following code snippet

creates a TextBlock control and displays it in Cell(0,0) that represents the

first row and first column of Grid. Values of color properties are assigned to corresponding properties of CellView control.

Clicking on the gray rectangle will change its color, and set the text to bold (I will deal with these triggers later). I am completely new to wpf and c#, so excuse if this is super trivial question. If you set it to Collapsed, all details will be invisible all the time. If you need WPF to populate datagrid, please refer to the following discussion on Microsoft’s Q&A blog. The Rows and Columns property of the UniformGrid are DependencyProperties, so you could bind them to properties on the DataContext to make them dynamic.

When designing WPF screens, sometimes it may be necessary to create a new Grid with number of rows and/or columns set dynamically. Number of child user controls that need to be populated in the parent user control are determined at run time and can change. The number of child user controls that need to be populated in the parent user control are determined at run time and can change. As you can see from the code listing, it’s mostly about expanding the details template into using a panel, which in turn can host more panels and/or

controls. Once a control is created and its position within Grid is

set, next step is to add control to Grid by using Grid.Children.Add method.

Basic controls

Dynamic grid is implemented as user control that contains DataGrid control bound to observable collection of collections of cell view models. In this implementation collection of cells is recreated each time if grid width or grid height is changed, and it leads to some application pauses. In the following post this issue is solved with asynchronous method that updates cell array. Also, other implementation for cells could be used, for example, 2-dimensional array of cells ICellViewModels[][] works well. In this implementation, collection of cells is recreated each time if grid width or grid height is changed, and it leads to some application pauses.

It must be easy to create the other columns as well, using the same logic that I used to create the Rows. I would try using a listview and change the https://traderoom.info/fibonacci-retracement-definition-how-to-use/ template to the style you want to use for your elements. This grid will always have consecutive numbers, with a color rectangle in front of it.

Grid with Dynamic Number of Rows and Columns – Part 1

The solution to me was pretty like the ones above, but I had to bind the ItemsSource in the back code. Then, on the .cs file of this page you must create a function with the code below. Connect and share knowledge within a single location that is structured and easy to search.

As you can see from the resulting screenshot, or if you run the sample yourself, the details are now shown below the selected row. As soon as you select

another row, the details for that row will be shown and the details for the previously selected row will be hidden. Enter your email address to follow this blog and receive notifications of new posts by email. The RemoveAt method of Grid.RowDefinitions deletes a row at

the given position.

How to create add and delete rows in WPF Grid Dynamically?

Method analyses necessary changes and remove or add rows and remove or add cell view models to rows. As was mentioned above, the code of this post is based on code from the previous post, so here, we focus on new or changed code. Dynamic grid is implemented as user control that contains DataGrid control bound to observable collection of collections of cell view models. There is an issue with binding to view size – as bindings are executed in single thread, new values of view width and height come in different moments.
