Remarks

Create a Date Picker Content Control

The code sample below creates a date picker control:

date picker in word processing

using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;

using (var wordProcessor = new RichEditDocumentServer()){

    wordProcessor.CreateNewDocument();
    Document document = wordProcessor.Document;
    var contentControls = document.ContentControls;

    var datePicker = contentControls.InsertDatePickerControl(document.Range.Start);
    datePicker.Date = DateTime.Now;
    datePicker.DateFormat = "dddd, MMMM dd, yyyy";
    datePicker.Color = System.Drawing.Color.RebeccaPurple;
    wordProcessor.SaveDocument("Content Controls Date Picker.docx", DocumentFormat.OpenXml);

    Process.Start(new ProcessStartInfo("Content Controls Date Picker.docx") { UseShellExecute = true });
}

Access Date Picker Content Controls

The SubDocument.ContentControls property returns all content controls in a document. Use the ContentControlBase.ControlType property to determine the content control type.

The code sample below retrieves all date pickers in a document:

using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;

using (var wordProcessor = new RichEditDocumentServer()) {

    Document document = wordProcessor.Document;
    var contentControls = document.ContentControls;

    var datePickers = document.ContentControls.Where(contentControl => contentControl.ControlType == ContentControlType.Date).Cast<ContentControlDate>();

    foreach ( ContentControlDate datePicker in datePickers )
    {
        // your code here
    }

Modify Check Box Content Controls

Use the ContentControlDate class properties to change the date picker parameters. The code sample below retrieves the date picker from the first paragraph and changes its date format:

using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;

using (var wordProcessor = new RichEditDocumentServer()) {

  wordProcessor.LoadDocument("Content Controls.docx");
  Document document = wordProcessor.Document;
  var contentControls = document.ContentControls;
  var firstParagraph = document.Paragraphs[0];
  for (var i = 0; i < contentControls.Count; i++) {
      if (firstParagraph.Range.Contains(contentControls[i].Range.Start) && contentControls[i].ControlType == ContentControlType.Date) {
          ContentControlDate datePicker = (ContentControlDate)contentControls[i];

          datePicker.DateFormat = "d MMMM yyyy";
          break;
      }
      wordProcessor.SaveDocument("Content Controls.docx", DocumentFormat.OpenXml);
  }
}

Remove Check Box Content Controls

The ContentControlCollection.Remove method allows you to remove specific content control. You can also specify whether to keep control’s contents when the controls is removed.

The code sample below removes all date pickers from the document:

using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;

using (var wordProcessor = new RichEditDocumentServer()) {
    Document document = wordProcessor.Document;
    var contentControls = document.ContentControls;

    for (var i = 0; i < contentControls.Count; i++)
    {
        if (contentControls[i].ControlType == ContentControlType.Date)
        {
            contentControls.Remove(contentControls[i], true);
        }
    }
}
