#Remarks

#Create a Scrollbar Form Control

The code sample below creates a scrollbar form control:

Workbook workbook = new Workbook();
workbook.LoadDocument("Document.xlsx");

var formControls = workbook.Worksheets[0].FormControls;

var cellRange = workbook.Worksheets[0].Range["B2:B8"];
var scrollbarFormControl = formControls.AddScrollbar(cellRange);
scrollbarFormControl.Min = 2;
scrollbarFormControl.Max = 15;
scrollbarFormControl.LargeChange = 10;
scrollbarFormControl.SmallChange = 1;

Note

The FormControlCollection.AddScrollbar method call adds a new item to both FormControlCollection and ShapeCollection.

#Obtain Scrollbar 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:

The FormControl.Id and FormControl.Name properties return the form control’s identifier and name.

#Modify Scrollbar Form Controls

Use the ScrollbarFormControl class properties to change scrollbar parameters. The code sample below obtains all scrollbars 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 scrollbars = formControls.Where(formControl => formControl.FormControlType == FormControlType.Scrollbar).Cast<ScrollbarFormControl>();
foreach (ScrollbarFormControl scrollbar in scrollbars)
{
    scrollbar.Shading3D = true;
}

Note

ShapeFormatBase.Fill, ShapeFormatBase.Outline, and FormControl.ShapeText property returns null for ScrollbarFormControl.

#Remove Scrollbar Form 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 scrollbars 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.Scrollbar)
        formControls.RemoveAt(i);
}
