The Definitive Guide to WPF Datagrids by MESCIUS inc MESCIUS inc.
Mastering these techniques with your WPF SQL Server DataGrid will significantly improve your application’s performance, reliability, and maintainability. The standard validation error indicator is a red exclamation mark which is displayed at the left hand side of the row. The DataGridRow has a ValidationErrorTemplate which defines the appearance of this indicator. With the example given below, the exclamation mark is rendered within a red circle in order to give it a more striking appearance.
Editing, Printing, Exporting
- Easily customize all aspects of the DataGrid appearance using the Theme Studio utility.
- The StatRow class represents a row that can be used to display statistical results.
- The data loaded in DataGrid looks like Figure 2, which shows the properties of the Author class a column names.
- The following code snippet sets the ItemsSource property of a DataGrid to List of Authors.
- For example, many WPF DataGrid features require custom converters and styles or rely on configuring the CollectionViewSource.
You only have to write a few lines of code to add a new record or update and delete existing records in a database via the grid. Fast, powerful, and mature, with a 13-year track record, this is the only WPF datagrid that provides a rich, fluid, and high-performance user experience. It is frequently updated and backed by a responsive support and development team whose sole ambition is your complete satisfaction.
The SearchControl provides powerful search capability, providing end-users with an easy to use UI for finding items in the datagrid’s cells. Users can search forwards or backwards, and use keyboard shortcuts. Works with Master/Detail views, collapsed groups, and also with data virtualization enabled. When a grid is in a table-view layout, the first n columns can be fixed so that they do not scroll with the grid content. Fixed columns are separated from their scrollable counterparts by a fixed-column splitter, which can be dragged to add or remove fixed columns. Likewise, column-manager cells can be dragged to the left or right of the fixed-column splitter to add https://traderoom.info/displaying-data-in-tables-with-wpf-s-datagrid/ or remove fixed columns.
The control provides built-in functionality to sort, filter, group, and find records. In this tutorial, I demonstrated how to connect to a SQL Server database and load data in a xamDataGrid. In this tutorial, we also saw how to add, update, and delete data via the data grid control and export data to a Microsoft Excel document.
The following code snippet sets background, row background, and alternative row background colors of a DataGrid. Now the last step is to set ItemsSource property of DataGrid. The following code snippet sets the ItemsSource property of a DataGrid to List of Authors. Merged column headers can be used to present data more clearly and logically. Columns can be grouped (“merged”) under these merged headers, as can other groups of columns. Merged headers and their columns can be moved (drag-and-drop, programmatically) and removed / added back.
You can use the sample code below or replace this section with your own code. The .NET ecosystem has always supported custom components that you can build yourself or purchase from other software development teams. In this article, we discuss the evolution of the .NET datagrid, the top features of a WPF datagrid, and how to use a datagrid in your WPF application code.
Built-in add new row
DataGrid supports right-to-left (RTL) rendering for users working in right-to-left languages like Hebrew, Arabic, or Persian. Tooltips display additional information in a pop-up window when the pointer hovers over cells in the DataGrid. Perform clipboard operations such as cut, copy, and paste within a control and between other applications such as Notepad or Excel. Users can change the visibility of columns at runtime using the customizable column chooser UI. Display the additional information of a row using a template. View the record template by expanding and collapsing the record as required.
A common challenge involves managing multiple tables simultaneously. Instead of individual updates for each table, we can use a single, unified approach. This involves creating a view or stored procedure that combines data from relevant tables, simplifying data access and manipulation. The WPF application then interacts with this consolidated data source. This streamlined approach minimizes the number of database interactions, leading to improved performance, especially when dealing with large datasets. The use of parameterized queries further enhances security by preventing SQL injection vulnerabilities.
The Standard .NET WPF Datagrid Features
As the introduction stated, the new DataGrid implements autosizing behavior. Troubleshooting a Decimal-data error in an RPGLE program using embedded SQL. Learn to optimize SQL database joins for faster query performance.
One of the benefits of WPF is that it’s the most easily extensible .NET platform due to its XAML-based architecture. With XAML, we can customize templates of components to add extra features. While that’s still more development work than setting a built-in feature, it’s still a lot easier than extending a control in Windows Forms or for the web.
The following slightly lengthy validation rule can be applied at cell and row level. The rule will check a column (or all the row’s columns) for length, unique, and null constraints. This rule iterates over all of the items within the binding group (i.e., the DataGrid row) probing them for errors.
You can also sort by caption summary values when the grid is grouped or by writing custom logic. To refilter the data items displayed in a view, the Refresh method can be called on the ItemsSource. To delete a record, simply select a row in the data grid and press the DELETE button on the keyboard.
A Stats Editor Control which gives the user the ability to view, add, edit and remove the statistics displayed in StatRows. Instead of the default context menu style (shown above), the built-in dialog control can be used for a different look/behavior (shown below). A third option is to provide a custom look to the context menu. I tested the new control, but now it faces it�s biggest test, YOU. Please let me know of any problems that arise while using this control. But never, ever, ever set the ReadOnly property to false unless you want trouble.
