c# WPF: ClipboardContentBinding does not work for advanced DataGrid-columns

This is built-in behavior and all you need to do to enable it is add aggregate functions to your columns and group your data. Below is an example of an Outlook-inspired application, which utilizes a few of the most commonly used controls and functionalities in WPF projects. There are a variety of articles across the web that can help you create a conventional Microsoft default WPF Grid, most of which you’ve probably already read. So I want to take a different angle here and share insights from my perspective as both a creator and customer of the Telerik WPF DataGrid. DevExpress desktop components were voted best-in-class by readers of Visual Studio Magazine. Download your free 30-day trial today and see why your peers consistently vote DevExpress #1.

Our themes come with color palettes that can personalize your UI even further. And yes, you can customize our pre-built application themes with the free DevExpress WPF Theme Designer. The following are a few of the themes included in our distribution. SelectionThe data grid includes a variety of selection modes. They are configured by the SelectionMode and SelectionUnit property.

WPF: ClipboardContentBinding does not work for advanced DataGrid-columns

Srinivas Commented on 7.July 2011Superb, very Nice Article. To disable add, update, and delete operations in xamDataGrid, you can make it read-only by setting its AllowEdit property to false. The RecordUpdating and the RecordUpdated events are fired when a record is being updated and when a record has been updated in the xamDataGrid respectively. This is where you also want to save your changes to the backend database.

Data needs to be available, manageable and actionable throughout the organization and data grids are the key ingredient for making that happen. In most cases, you already know the schema of the data prior to the application launch. But sometimes this information is obtained only after the app starts.

You can also control the size of the page, which is the number of items displayed at once on the screen. You can take advantage of predefined format rules or create custom rules as needed. The Data Grid ships with both a design-time and runtime Conditional Formatting Rule Editor – so you and your users can create, edit, and delete format rules as and when needed. With only one line of code per line of detail, our Data Grid allows you to construct master-detail layouts of any complexity – with multiple nesting levels and multiple details at each level. You are never limited to how information is displayed for detail records – Detail Rows can display information as your needs dictate. You can specify a theme when you ship your app or allow end-user to modify the look and feel of your WPF application on the fly.

Flexible Row

As you can see from Figure 1, Infragistics WPF controls starts with XamControlName and the XamDataGrid is the DataGrid control. XamDataGrid provides built-in data-binding and data operations such as filtering, search, sorting, and others. 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. Also, a tooltip is defined that displays the validation error message.

Check out Gina’s blog post for a step-by step tutorial on how to add EF core to your WPF project. You can find one demo project in the series GitHub repository. It uses EF Core in a WPF application with migrations, SQLite and everything, and it displays the data in a DataGrid.

This feature can be useful in situations in which your data is truly hierarchical in nature and drilling down makes sense. This can also reduce the cluttering and data overflow in large data sets. When combined with lazy loading it can lead to performance improvements as well, because you will be fetching only the data you are actually showing on the screen. Experience the DevExpress difference and see why your peers consistently vote our products #1. With our Universal Subscription, you will build your best, see complex software with greater clarity, increase your productivity and create stunning applications for Windows, Web and your Mobile world.

The xamDataGrid is one of the richest data controls available for WPF. 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.

Code of conduct

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 ? There are “Ending” events, but no “Ended” events; therefore, the data visible to event handlers is not in its committed state. Data displayed in a table with rows and columns is both easy to manipulate and represent, thanks to a variety of features, such as filtering, sorting and grouping. In this “big data”-driven world we live in today, people often work with huge data sets on a daily basis, across manufacturing, finance, banking, healthcare, retail, automotive and other industries.

If you have a million rows of data and you want to sort them, this can be time consuming if not done properly. However, a database can sort a dataset much faster if an index exists on the subject column. Displaying data is great, but the Telerik DataGrid also allows you to modify the data it is presenting.

The hierarchical https://traderoom.info/ for the DataGrid handlesself-referencing data setsas well. So, if your data has a ParentID relationship for example, your data is good to go. If not all of your data is forming a hierarchy you can hide or show the row expander icons by binding it directly to your data.

The latter gives you complete control over the generated columns and the generation process itself. 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.

Massive datasets are never a problem.

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. Row level validation makes use of the new .NET SP1 feature, BindingGroups. 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.

• We chose DevExpress for WPF and MVVM because of the huge range of possibilities it offers.
• There are dark and light themes, a Material and touch-friendly theme.
• If some of the missing features are a must, you can combine the two components together.

The Infragistics product, Ultimate UI for WPF provides rich, fast, modern controls for WPF. The Ultimate UI for WPF product consists 80+ WPF controls and starts at the US $899 with standard support. I will show you how to build a complete data-driven WPF app using Visual Studio 2017, C#, and Infragistics DataGrid control, XamDataGrid.

I really appreciate the work of the support team and the whole DevExpress team providing such good tools and support. Straightforward API to write custom server requests for any server or database, including Rest API, gRPC services, NoSQL databases, custom WCF services, EntityFramework, etc. Like previous years, DevExpress dominated Visual Studio Magazine’s 2022 Readers Choice Awards. We thank all our loyal users for casting their vote on behalf of DevExpress. Second thing you need to do is defining a template how the groups should look like.

Another benefit of theNoXamlassemblies is that you cancustomize the built-in themesvery easily. You can change absolutely anything, starting from a color to completely retemplating the whole component. When you just need to give a specific component some style you will be pleased to know that there are many different APIs for doing that.

Validation

With the DevExpress WPF Data Grid, you can deliver intuitive user experiences and error-free data input. From TextBox controls and Date Pickers to our powerhouse Data Lookups, you can incorporate 20+ individual data editors within grid cells with absolute ease. As you can see in Figure 36, there is a “+” button that by clicking it will add a new row to the data grid.

This article will present a few common validation scenarios, demonstrating how the DataGrid can be configured to perform these tasks. Both are, of course, possible; however, it is my preference that the validation logic should not live in the presentation layer. However, it should be noted that the validation support for the WPF DataGrid is currently a bit patchy. The row level validation which was advertised as part of the first DataGrid CTP didn’t quite make the release, and the recently released DataGrid v1 still has a number of validation related issues.

Also, the lack of a DataGrid within the WPF APIs was an excellent opportunity for third party component providers; see Michael Sync’s blog for a roundup of the five leading third party WPF DataGrids. The SelectionMode property decides if the DataGrid allows only a single row or multiple rows selection. The HorizontalScrollBarVisibility and VerticalScrollBarVisibility properties of type ScrollBarVisibility enumeration control the horizontal and vertical scrollbars of the DataGrid.

• Add to that the datagrid’s zero-lag data virtualization, and you have the fastest WPF datagrid around—in performance and feel.
• Basic effects like hover and selection as well as grouping are still enabled, so make sure you check your grid before enabling those light templates.
• If these column types do not fulfill your needs, either in read-only mode or when the cells are in edit mode, then you can define your own column type using templates.
• IQueryable allows you to request only the objects that you need from the comfort of dotNet.

Currently, I feel that the “bar” for developing wpf advanced datagrid applications is quite high, a richer design-time experience. All the automated generation of bound controls would certainly help open up WPF to a far wider audience. For details of how this style was assembled, download the article source and pick apart the code. There is nothing special in there, just the usual application of styles and cut-n-paste control template modification. The workaround given here uses validation to ensure that all the DataTable constraints are satisfied before the updates are committed.

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. Some of these properties have corresponding components that can be styled using implicit style. You can style all rows using a single style, either set to theRowStyleproperty or an implicit style that targetsGridViewRow.
