However, in some situations you might want to manually define the columns shown, either because you don’t want all the properties/columns of the data source, or because you want to be in control of which inline editors are used. 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. That means they stay visible while you scoll horizontally through all columns. This is a useful feature to keep a referencing column like an ID or a name always visible to keep your orientation while scrolling. You can specify a RowDetailsTemplateSelector that selects a data template according to the type or data that this row contains. To do this, create a type that derives from DataTemplateSelector and override the SelectTemplate method.

We could bind the DataGrid directly to our customer collection, List; however, we need to ensure that the UpdateCustomer and DeleteCustomer methods on our DAL interface are invoked at the appropriate points in time. One approach that we might take is to handle the events / commands exposed by the DataGrid in order to determine what action it has just performed or intends to perform on the bound customer collection. However, in doing so, we would be writing integration code that is specific to the DataGrid. What if we wanted to change the UI to present a ListView and a number of TextBoxes (details view)?

  1. Xceed offers an advanced version of this datagrid with certain added features.
  2. Display rows at the top and bottom of the grid with data that is not bound to the ItemsSource.
  3. To enable grouping you have to define a CollectionView that contains to least one GroupDescription that defines the criterias how to group.
  4. The View must be a valid instance or subclass of TableView (ex. TableFlowView, TreeGridflowView).
  5. Its rich feature set includes functionalities like data binding, editing, sorting, filtering, grouping, and exporting to Excel and PDF file formats.
  6. You can set the SfDataGrid.SelectionMode property to specify whether a user can select single row or cell, or multiple rows or cells.

Validation with Bound DataSets

This article provides a number of simple usage examples which will hopefully be of use to anyone considering using the WPF DataGrid.

Statistics Rows and Summary Rows

Set SfDataGrid.AllowDeleting property to specify whether user can delete rows by pressing Delete key. You can customize sorting by handling the SfDataGrid.SortColumnsChanging and SfDataGrid.SortColumnsChanged events. To cancel the default sort, set the Cancel property to true in SfDataGrid.SortColumnsChanging event. By default, the entire row is selected when a user clicks a cell in a SfDataGrid. You can set the SfDataGrid.SelectionMode property to specify whether a user can select single row or cell, or multiple rows or cells. Set the SfDataGrid.SelectionUnit property to specify whether rows can be selected, or cells can selected.

In the items argument you get the data and you can determine which data template to display. Stacked headers (multiple header rows) allow users to show unbound header rows. The datagrid allows users to select multiple items or cells using Left-Click and then dragging the mouse within the datagrid. This allows range selection to be performed without having to hold the Shift key on the keyboard. The settings of a grid and its elements can be persisted and re-applied using the SaveUserSettings and LoadUserSettings methods, respectively.

Data binding

Navigate to the Xceed Data Grid for WPF product page and click on the “Download” button. You will be prompted to fill out a short registration form to access the free trial or purchase the full version. You can handle the selection operations with the help of SfDataGrid.SelectionChanging and SfDataGrid.SelectionChanged events of SfDataGrid. Second thing you need to do is defining a template how the groups should look like.

There are “Ending” events, but no “Ended” events; therefore, the data visible to event handlers is not in its committed state. A better approach would be if we could adapt our collection of Customer objects in such a way that they could be bound to any suitable WPF UI control, with add/edit/remove operations synchronised with the database via our DAL. The appearance of a data grid and its inner elements, such as rows, cells, columns, headers, and summary rows, can be customized easily using styles and templates. The DistinctValuesConstraint property can also be set to determine if the distinct values are to be filtered according to the result of previous auto-filtering operations.

The action item for developers is to integrate Xceed Data Grid into their WPF applications, experiment with its various features, and tailor the data grid’s appearance and functionality to align with their specific requirements. By turning off automatically generated columns using the AutoGenerateColumns property, you get full control of which columns are shown and how their data should be viewed and edited. As seen by the example of this article, this opens up for some pretty interesting possibilities, where you can completely customize the editor and thereby enhance the end-user experience. In the markup, I have defined a couple of columns and then I use the RowDetailsTemplate to specify a template for the row details. When a grid is in a table-view layout, its data items can display detail data that is usually provided by the detail descriptions defined in the DataGridCollectionView or DataGridCollectionViewSource to which the grid is bound.

The columns that are displayed in a grid can be chosen by the user through the column-chooser context menu, which can be enabled by setting the AllowColumnChooser defined on the view to true. A column’s ShowInColumnChooser property determines whether a column’s title is displayed in the menu, allowing its visibility to be manipulated by an end user. The example in the attached source code presents a UI for editing the Customer table. One other subtlety of this example is that the primary key is read only, because the generated DataSet’s update methods assume that the primary key has not been modified. However, when the data grid selection changes to the empty row at the bottom, the column’s read-only state is toggled to allow the user to add a new Customer row.

Xceed Data Grid is a powerful, feature-rich, and highly customizable control that allows you to display, edit, and manage data in a tabular format. Designed specifically for WPF, it takes full advantage of the platform’s capabilities, providing a seamless experience when working with large amounts of data. This guide aims to help you understand the core concepts and components of Xceed Data Grid and guide you through the process of integrating it into your WPF applications. The first thing you may want to do is try the product using our click once installer. Editing can be enabled by setting SfDataGrid.AllowEditing property to true .

If we copy our customer data into an ObservableCollection and bind this to the DataGrid, we can handle the CollectionChanged event and perform the required operation on the DAL. The following code snippet shows how the CustomerObjectDataProvider (which is defined as an ObjectDataProvider in the XAML) constructs an ObservableCollection of CustomerUIObjects. These UI objects simply wrap their data object counterparts in order to expose the same properties. 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.

If you modify the structure of your database, perhaps to optimise performance, the generated DataSet will have to be updated and also the user interface code. A second data source is added, again via the ObjectDataProvider, with the window displaying two DataGrids, each bound to their respective data sources. To take full advantage of these capabilities, developers should first download and install the Xceed Data Grid library from the official Xceed website or access it through the NuGet package manager. Familiarizing themselves with the basic usage of the control, such as creating a simple data grid, binding data, and configuring columns, will serve as a solid foundation for further exploration. By default, the SfDataGrid control generates the columns automatically when value assigned to SfDataGrid.ItemsSource property. The type of the column generated depends on the type of data in the column and the attribute of the property the column bound with.

A master-details view (nested grid view) can be represented through nested grids that can be expanded and collapsed. Functionalities like editing, sorting, filtering, and grouping are supported. 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 do this by setting the GroupStyle to something like the following snippet. By clicking “Post Your Answer”, you agree to our terms of service and acknowledge you have read our privacy policy.

The WPF DataGrid control is compatible with Coded UI and UFT (formerly QTP) automation tools to automate an application with the DataGrid control. Localize all the static, default strings in the WPF DataGrid to any supported language.

Validation within the WPF DataGrid occurs both at the cell level and at the row level. Cell level validation makes use of the standard Binding validation mechanisms which are described in great detail in this excellent CodeProject article. A binding group does pretty much what you would expect, it groups together a number of bindings, allowing them to be validated as a single entity. A detailed overview of binding groups can be found on Vincent Sibal’s blog, and their usefulness extends far beyond that of validating DataGrid rows. The ObservableCollection class is a good candidate for our data binding needs. It exposes a CollectionChanged event which is fired whenever items are added or removed from the collection.
