Description

In this KB article, we will demonstrate how to set text alignment to left and centered programmatically.

Solution

To set all table cell content alignment to left and centered:

1. Retrieve the table from the document using EnumerateChildrenOfType<Table>().
2. Clear the current selection.
3. Set the selection to cover the entire table.
4. Use the RadDocumentEditor to apply the alignment changes.
5. Clear the selection after applying the alignment.

Here is the sample code:

C#

var tables = richTextEditor.Document.EnumerateChildrenOfType<Table>();
var table = tables.FirstOrDefault();

richTextEditor.Document.Selection.Clear();

var start = new DocumentPosition(richTextEditor.Document);
start.MoveToDocumentElementStart(table);
richTextEditor.Document.Selection.AddSelectionStart(start);

var end = new DocumentPosition(richTextEditor.Document);
end.MoveToDocumentElementEnd(table);
richTextEditor.Document.Selection.AddSelectionEnd(end);

RadDocumentEditor editor = new RadDocumentEditor(richTextEditor.Document);
editor.ChangeTableCellContentAlignment(RadTextAlignment.Left, Telerik.WinForms.Documents.Layout.RadVerticalAlignment.Center);
richTextEditor.Document.Selection.Clear();
