Remarks
Create a Group Box Form Control
The code sample below creates a group box control:
using DevExpress.Spreadsheet;
Workbook workbook = new Workbook();
workbook.LoadDocument("Document.xlsx");
var cellRange = workbook.Worksheets[0].Range["B2:F6"];
var groupBox = formControls.AddGroupBox(cellRange);
groupBox.PlainText = "Group Box";
Note
The FormControlCollection.AddGroupBox method call adds a new item to both FormControlCollection and ShapeCollection.
Obtain Group Box Form Controls
The Worksheet.FormControls property obtains all form controls in a worksheet. You can use one of the following ways to obtain a specific form control:
- Access the item in the collection by its index
- Call the FormControlCollection.GetFormControlsByName method
- Call the FormControlCollection.GetFormControlById method
The FormControl.Id and FormControl.Name properties return the form control’s identifier and name.
Modify Group Box Form Controls
Use the GroupBoxFormControl class properties to change group box parameters. The code sample below obtains all group boxes and enables 3D shading:
using DevExpress.Spreadsheet;
using System.Linq;
Workbook workbook = new Workbook();
workbook.LoadDocument("Document.xlsx");
var formControls = workbook.Worksheets[0].FormControls;
var groupBoxes = formControls.Where(formControl => formControl.FormControlType == FormControlType.GroupBox).Cast<GroupBoxFormControl>();
foreach (GroupBoxFormControl groupBox in groupBoxes)
{
groupBox.Shading3D = true;
}
Note
ShapeFormatBase.Fill, ShapeFormatBase.Outline property returns null for GroupBoxFormControl.
Remove Group Box Controls
Call the FormControlCollection.Remove or FormControlCollection.RemoveAt method to remove a form control. The FormControlCollection.Clear() method removes all form controls from a worksheet.
The code sample below removes all group boxes from a worksheet:
Workbook workbook = new Workbook();
workbook.LoadDocument("Document.xlsx");
var formControls = workbook.Worksheets[0].FormControls;
for (int i = formControls.Count - 1; i >= 0; i--) {
if (formControls[i].FormControlType == FormControlType.GroupBox)
formControls.RemoveAt(i);
}
