Remarks
You can set a section’s page orientation in the following ways:
Select the Page Layout → Orientation → Portrait ribbon command to set page orientation of the selected section to portrait.
Select the Page Layout → Orientation → Landscape ribbon command to set page orientation of the selected section to landscape.
Call the section’s ChangePropertiesAsync method.
The following code snippet sets the orientation of every page in the open document to portrait.
<DxRichEdit @ref="richEdit" />
@code {
DxRichEdit richEdit;
Document documentAPI;
/* Surround the code that contains an asynchronous operation with a try-catch block to handle
the OperationCanceledException. This exception is thrown when an asynchronous operation is canceled. */
try {
documentAPI = richEdit.DocumentAPI;
var sections = await documentAPI.Sections.GetAllAsync();
foreach (Section s in sections)
await s.ChangePropertiesAsync(properties => {
if (s.Landscape == true)
properties.Landscape = false;
});
}
catch (OperationCanceledException e) {
Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
}
}
If a user changes a page orientation, the PageSize.Width property value becomes the PageSize.Height property value and vice versa. If you change the section’s PageSize.Height and/or PageSize.Width property value, the Rich Text Editor updates the Landscape
property with the matching value.
