get CheckBoxFormField by name

[ProPotsdam]

Spire.Office for .NET V. 8.2
Developer Subscription

I have a form field of type "CheckBoxFormField" with the name "Kontrollkaestchen27" and would like to show the checkbox as selected.
II determine the control over its Name.

CodeBehind (C#):

using Spire.Xls;
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;


Document _doks = new Document();
Section section = _doks.Sections[0];
CheckBoxFormField formField = section.Body.FormFields.ContainsName["Kontrollkaestchen27"];
formField.Checked = true;

I receive the error message:

Cannot apply indexing with [] to an expression of type 'method group'

What's going wrong?

Hello,

Thank you for your inquiry.
Based on the error information you provided, you referenced a method group instead of a specific object. I have made modifications to the code you provided and tested it using the Spire.Office Platinum (Hot Fix)Version: 8.8.0 without any issues. Here is the modified code:

Code: Select all

           Document _doks = new Document();
            Section section = _doks.Sections[0];
            CheckBoxFormField formField = section.Body.FormFields["Kontrollkaestchen27"] as CheckBoxFormField;
            formField.Checked = true;
