This example demonstrates how to create a ASPxNewsControl-like layout and functionality using the BootstrapCardView control.
For this, create a card template. This template renders images, news texts, news dates, and news headers. Use Style.css for styling a template layout. Use javascript functions to get news text, a cursor position, and show details of text in the BootstrapPopup control window.

How to customize PDF Viewer Toolbar Items
The following example shows how to customize PDF Viewer Ribbon. Starting with version 14.1.5, this can be done using actions.
In previous versions, it is necessary to override the default PdfViewerControl's RibbonTemplate and add the required bar items to the newly defined RibbonControl.

Hi,
It seems that in this example you are adding a custom button (MainWindow.xaml.vb):
Private Sub bCustomItem_ItemClick(ByVal sender As Object, ByVal e As DevExpress.Xpf.Bars.ItemClickEventArgs)
Dim w As New WinUIDialogWindow()
w.Content = "Hello world!"
w.ShowDialogWindow(MessageBoxButton.YesNo)
End Sub
But I can't see how it is declared (in MainWindow.xaml it doesn't appear).
How can I add a custom button?
Thanks.
Daniel.

Drag-and-drop data rows from one grid to another
This is an example for the Drag-and-drop data rows from one grid to another Knowledge Base article. Please refer to the article for the explanation.
[UPDATED]:
Starting with version 17.2, you can attach Drag And Drop Behavior to two GridControls to implement drag-and-drop without writing additional code.

GridControl grid = sender as GridControl;
grid always null ???
Thanx Dear fro reply me i'll do it
Added By: david ola at: 11/5/2015 5:41:44 AM1. Can you copy instead from the original grid rather than deleting the row being dragged? In other words, after dragging a particular row, let the original grid still have the row, as opposed to the row disappearing.
2. Can you modify the code such that the row being dragged can be captured and displayed, modified before it is dropped?
David,
Just change the DragDrop handler to not import and delete the source and instead create a copy of the DataRow and import that into the second grid.
Added By: Sasha (DevExpress Support) at: 11/5/2015 11:05:33 AMHello David,
Here is a small code that illustrates Brendon's idea:
[C#]privatevoidgrid_DragDrop(objectsender,System.Windows.Forms.DragEventArgse){GridControlgrid=senderasGridControl;DataTabletable=grid.DataSourceasDataTable;DataRowrow=e.Data.GetData(typeof(DataRow))asDataRow;if(row!=null&&table!=null&&row.Table!=table){table.ImportRow(row);table.Rows[table.Rows.Count-1]["Column1"]="modified";}}
Please review it and let me know if it helps.
Added By: david ola at: 11/6/2015 5:07:05 AMThanks guys, but I am still having a problem: the original data in the first grid is still being modified. Here is my code:
GridControl grid = sender as GridControl;
DataTable table = grid.DataSource as DataTable;
DataRow row = e.Data.GetData(typeof(DataRow)) as DataRow;
int newNum = 0;
num += 1;
if (row != null && table != null && row.Table != table)
{
DataRow rowmod = row;
rowmod[0] = "original modified";
MessageBox.Show(rowmod[0].ToString());
newNum = num % 2;
if (newNum == 0)
{
table.ImportRow(rowmod);
}
}
I want only the imported row to be modifiable without any changes to the original data.
My intention is to allow the user to drag the row, display that row in a form for possible modification, before dropping it in the second grid. The user should also be able to cancel the operation without making any changes to either grid, even after displaying the row in the form.
So far I have been able to display and modify the data, and even choosing to cancel mid-operation (using the modulo example). But it keeps making changes to the original data, which I don't want.
Hello David,
I've created a separate ticket for your inquiry: How to modify the 'Drag-and-drop data rows from one grid to another' example so that the row is not deleted after dragging. Let's continue discussing it in that thread.

How to use the ASPxSpreadsheet control as a property editor in an XAF ASP.NET WebForms application
Scenario
I want to display my business object that has a byte array property as an Excel document allowing users to modify the content and save it to the database. ASPxSpreadsheet is an appropriate component for this task, but how to implement a Web Property Editor based on it?
Backgrounds
Unlike regular ASP.NET editors and controls, ASPxSpreadsheet is a front-end to a document service similar to Google Docs that will be running on your web site if you add this component to your application. Because of this, a property editor based on the ASPxSpreadsheet component has some specific features.
1. If a user opens a document, the next user who opens the same document will see the actual document content even if the first user did not save it to the database.
Image may be NSFW.
Clik here to view.![]()
2. The Refresh action does not discard changes made in the document. The actual document state is stored in the service, and the content stored in the database is used as backup.
3. The Save action updates the content stored in the database. If the user closed a document without clicking the Save action, changes made to the document will be stored on the service and another user can save them to the database.
The property editor demonstrated in this example works with properties of a specific type - SpreadsheetDocument, and does not write any changes to a property. Instead, it modifies referenced objects directly. The SpreadsheetExample.Module\BusinessObjects\Report.cs (SpreadsheetExample.Module\BusinessObjects\Report.vb) file contains a class that has a property of the SpreadsheetDocument type. Note that this property is considered a part of the persistent object (that is why it has the Aggregated attribute) and automatically initialized with the value within the AfterConstruction method.
The editor implementation is simple. Refer to the SpreadsheetExample\SpreadsheetExample.Module.Web\Editors\SpreadsheetEditor.cs (SpreadsheetExample\SpreadsheetExample.Module.Web\Editors\SpreadsheetEditor.vb) file for details. It uses the ASPxSpreadsheet.Open and ASPxSpreadsheet.SaveCopy methods to synchronize the opened document with the database. Documents are identified by the persistent object's key property. This allows opening a separate document for each record in the database.

How to separate data between employees and managers of different departments using security permissions in XPO
Scenario
This example demonstrates how to use the new security system to implement the following security roles:
- Users (Joe, John) can view and edit tasks from their own department, but cannot delete them or create new ones. They also have readonly access to employees and other data of their own department.
- Managers (Sam, Mary) can fully manage (CRUD) their own department, its employees and tasks. However, they cannot access data from other departments.
- Administrators (Admin) can do everything within the application.
All users have empty passwords by default.
Steps to implement
1.Permissions at the type, object and member level (with a criteria) are configured in the MainDemo.Module/DatabaseUpdate/Updater file. Take special note that for building a complex criteria against associated objects, the ContainsOperator together with the built-in CurrentUserId and IsCurrentUserInRole criteria functions. For greater convenience, strongly typed criteria for permissions are accompanied with their string representation.
2. The SecuredObjectSpaceProvider is used in the CreateDefaultObjectSpaceProvider method of the XafApplication descendants located in the WinForms and ASP.NET projects.
3. Permission requests caching is enabled via the IsGrantedAdapter.Enable method in the MainDemo.Module\MainDemoModule.xx file (see the T241873 ticket for more details).
4. The Department, Employee and EmployeeTask classes are implemented in the MainDemo.Module/BusinessObjects folder. To quickly understand relationships between involved business classes, their class diagram is attached.

1. See also the functional tests in the MainDemo.EasyTests folder for more details on the tested scenarios.
2. For versions older than v15.2.5, be aware of the issue described in the Security - The "Entering state 'GetObjectsNonReenterant'" error may occur while saving data if a permission criteria involves a collection property thread.

This is a great sample. There is one error, or it is not clear in the description. 'Users (Joe, John) can do everything with their own tasks and can also view data of their own department;' implies that Joe has read only access to Mary's tasks, which is not true. The code below fixes that.

To change ASPxGridView's data from the client side, there are appropriate ASPxClientGrid methods:
AddNewRow
DeleteRow
StartEditRow
To save or cancel changes, there are:
UpdateEdit
CancelEdit
The following example implements a custom defined toolbar with ASPxButtons, which perform all the editing capabilities over a grid's data source.
Note: to distinguish records, the property AllowFocusedRow should be enabled for grid.

I am having a hard time getting the buttons to work. Am i missing something on the backend which might stop it from working. Is there a place i can get more direction or post my code ?

OBSOLETE - How to create a Card View with editing capabilities using ASPxGridView
Starting with v15.2, we provide the ASPxCardView control, which supports CRUD operations out of the box:
ASPxCardView - Edit Modes
ASPxCardView - How to implement the CRUD (create, read, update, delete) functionality similarly to FormView and DetailsView
For previous versions:
To provide editing capabilities, you can add the ASPxButton into the DataRow template. Set its AutoPostBack property to False, and attach a script to the client-side Click event. In the script, call the client-side ASPxClientGridView.StartEditRow method and pass the current row visible index as an argument. Use the Container.VisibleIndex property from inline code to get the index.
To add new rows, add a similar button to the StatusBar template and call the ASPxClientGridView.AddNewRow method in its Click event.

How to use the ASPxFileManager metadata property
This new feature (FileManagerItemProperties.Metadata Property, starting from the release 17.2) provides access to a collection of an item's metadata. You could view metadata by clicked "Properties" in the corresponding item context menu. For this, create a custom file system provider, override base GetFiles and GetFolders methods, add key-value dictionary pairs to properties of a corresponding FileManagerFile or a FileManagerFolder object. Handle the client-side event SelectionChanged to get the currently selected element. Use the client-side method GetMetadata to get the metadata dictionary of the element. Then, compose a text from keys and values and assign it as the ASPxPopupControl content.

How to obtain the appointment or time interval selected by an end-user
This code example shows how to work with selected appointment and time intervals in code.
When an end-user tries to create a new appointment or edit an existing one, the Scheduler checks the selected appointment or time interval and shows necessary notifications.

How to create ASPxFileManager with metadata support using Entity Framework and a database as a filestore
This example illustrates how to get metadata from folders and files.
The ASPxFileManager control provides access to metadata of files and folders starting with the 17.2 version. It has the FileManagerItemProperties.Metadata property that contains a dictionary with metadata. The Metadata property is used to specify the item's metadata using an appropriate FileManagerFile.FileManagerFile or FileManagerFolder.FileManagerFolder constructor.
The ASPxFileManager has the ASPxClientFileManagerItem.GetMetadata method, which is used to get the current File Manager item's metadata on the client side.

ASPxGridView - How to edit a DateTimeOffset column
This example demonstrates how to edit the DateTimeOffset structure using the ASPxGridView control. The DateTimeOffset represents a date-time data structure which defines a point relative to the UTC time zone. Our ASPxDateEdit editor doesn't support the DateTimeOffset type out of the box. However, it is possible to implement this task with two editors: the ASPxDateEdit is used to edit Date and Time parts of a DateTimeOffset value, and the ASPxComboBox is used to edit a time zone. Put these editors into the EditItemTemplate of a column which displays values from the DateTimeOffset field. When a row is updated, it is necessary to combine modified values into the DateTimeOffset structure manually. You can get them via the e.NewValues collection in the RowUpdating event handler. In this example, the UpdateGridDataSet method is used to save the DateTimeOffset value to a data object.

How to implement drag and drop between a legacy scheduler and a grid
Important: This example demonstrates a manual drag-and-drop implementation for DXGrid and a legacy Scheduler control. To learn more on how to implement a similar functionality using our new Scheduler and the built-in Drag-and-Drop functionality which became available in version 17.2, refer to the Data Grid > Scheduler Integrationinteractive demo.
This example illustrates how to implement drag and drop for appointments between a SchedulerControl and a GridControl. Note that we handle the PreviewMouseDown and PreviewMouseMove events of the TableView Class to initiate drag-and-drop operations for the GridControl (we use DragDrop.DoDragDrop Method for this purpose), whereas this operation is initiated automatically for the SchedulerControl (if the OptionsCustomization.AllowAppointmentDrag Property has its default value). The PreviewDrop event of the TableView and SchedulerControl.AppointmentDrop Event are handled to process SchedulerDragData dropped in the GridControl and SchedulerControl respectively.
Note: Rows in the GridControl are dragged via the RowIndicatior (see the screenshot in the TableViewHitInfo Class help section) in this example.
