Displaying data table in C# WPF application

wpf dynamic table

To use column-based grouping, you must bind the data grid to a CollectionView, and this is then bound to the data itself. You can define a CollectionViewSource in the window’s resources and choose a column to group the rows. Object tagging is the functionality that allows objects to be tagged to a control. This can be used in situations where the control is available, but an object cannot be accessed using standard application logic.

  1. I wanted to bind ProductName from RestaurantProduct through records and bind and then show like buttons.how can i bind that to uniform panel?
  2. You can now easily plot the values of the data table on different types of charts.
  3. Find centralized, trusted content and collaborate around the technologies you use most.
  4. Connect and share knowledge within a single location that is structured and easy to search.
  5. Two DataGridTextColumns are instantiated for the first and the last name, and the cell content are bound to the data row through the binding to the row’s respective fields.

This blog will show how to connect a FlexChart to a FlexGrid to create a bound MVVM (Model-View-ViewModel) scenario similar to Microsoft Excel. Users can add, delete and modify items in FlexGrid, which will reflect in FlexChart. JSON is one of the https://traderoom.info/ most widely used data formats, but working with it can be challenging. In this section, we are going to see two ways data can be retrieved from a JSON string. Changing the SelectionMode to Single only allows the user to select a single item.

The relative source of the bound control is set to the DataGridCell, found as an ancestor of the CheckBox control (the binding is defined on the CheckBox level). At the contrast of the Grid object witch is defined in the System.Windows.Controls, the table object is defined in the System.Windows.Documents namespace. Moreover, and at the contrast of the grid element, the Table element must be contained in one of those containers. Create the binding by setting the grid’s ItemSource property to inherit from the data context.

Data Handling

The user row is fetched from the DataGridCell’s DataContext, which contains the DataRowView instance that has the user row in its Row property. The role is retrieved from the ColumnTag that is assigned to the column when it was added. The relative source of the bound control is set to the DataGridCell, found as an ancestor of the CheckBox control . Values of color properties are assigned to corresponding properties of CellView control. View model for each cell implements ICellViewModel interface that defines property for data model that implements ICell interface and command for changing state for the cell. The CheckedBoxOnChecked method is called whenever the check box state is modified.

The user data grid column definition is stored in the UserRolesColumns collection. This means that the default columns, the user’s first and last name, have to be in this collection too. Two DataGridTextColumns are instantiated for the first and the last name, and the cell content are bound to the data row through the binding to the row’s respective fields. This article describes a method many-to-many relations can be displayed and modified in a WPF datagrid control. The post is devoted to the Wpf datagrid with cells that have defined fixed size but a number of rows and columns is updated dynamically in order to fill all available space.

Dynamic tables depends on item type(WPF)

In this first part, I focus on the solution of handling dynamic columns. 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. 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 constructor and starts or restarts each time one view height or view width are changed. The ObjectTag itself is a DependencyProperty that can be attached to any type of control that is derived from DependencyObject. The data model of this sample consists of a User and a Role table, and a UserRole table that is the correlation table between the other two tables.

The first thing you should notice is how the StackPanel doesn’t really care whether or not there’s enough room for the content.

In the case of this sample, the available control is the CheckBox in the DataGridCell and the required object is the role that corresponds to the column. For example, such a grid could be used in chess or checkers games for 8×8 field. The post showcases a WPF datagrid with dynamic columns where the number of rows and columns is defined but all cells have the same size.

The below wpf dynamic table shows how you can use these properties to create a complex table header. Changing the SelectionUnit to Cell only allows for table cells to be selected, not whole rows. DataGrid is a data shaping component that allows the end user to manage the data and also display the data on the screen.

Connect and share knowledge within a single location that is structured and easy to search. In Windows Presentation Foundation , the datagrid is a highly-adaptable control for displaying information in tables in your Windows desktop applications. While naturally suited for tabular data, it is flexible enough to present many different kinds of dynamic content. Using it from desktop applications is very similar to how it can be used on the web with Silverlight, or in Windows Phone applications. The following code snippet demonstrates how to create a bar chart from the data table. With the JSON data converted into a data table, it is ready to be mapped into the WPF Charts control.

An entry in the UserRole table means that the user has a role assigned (referenced by the role’s id). Changing the SelectionUnit to CellOrRowHeader allows individual cells to be selected by clicking them, and entire rows to be selected by clicking the row headers. IsReadOnly https://traderoom.info/displaying-data-in-tables-with-wpf-s-datagrid/ – when true, prevents the user from double-clicking a cell to edit its contents. CanUserSortColumns – allows the user to sort the data in the table by clicking on column names. CanUserResizeColumns – allows the user to change the width of columns in the table.

View model of dynamic data grid contains cell, view and grid sizes, data model for cell set, and collection of collections of cell view models. Grid size, i.e. number of rows and columns, is calculated as view size divided by cell size. 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. Dynamic grid is implemented as user control that contains DataGrid control bound to observable collection of collections of cell view models.

You will want to make your real view models implement INotifyPropertyChanged of course. If you need WPF to populate datagrid, please refer to the following discussion on Microsoft’s Q&A blog.

As you can see, the controls still go from top to bottom, but instead of having the same width, each control is aligned to the left, the right or center.

The data grid control’s column property is declared as read-only, so it cannot be bound to a view model property. The DataGridColumnsBehavior is an attached behavior that overcomes this limitation. Dynamic grid is implemented as user control that contains DataGrid control bound to observable collection of collections of cell view models. The DataGridCheckBoxColumn binds the check box control to a boolean property of the data in the row that it is displaying.

It is a good in-memory database with referential integrity, and it contains built-in notification delegates that publish the insertion, removal and modification of data rows. Its contents can be stored to an XML file, which is used as a persistence mechanism in this example. The data model of this sample consists of a User and a Role table, and a UserRole table that is the correlation table between the other two tables. An entry in the UserRole table means that the user (referenced by its user id) has a role assigned (referenced by the role’s id). If there is no entry for a certain user-role combination, then that means that the user in question does not have the corresponding role assigned. You can look at the WPF grid example in the image below, which shows a 10×5 grid table.
