XRControlCollection Class

A collection of XRControl objects.

Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v23.1.dll

NuGet Package: DevExpress.Reporting.Core


public class XRControlCollection :


The XRControlCollection.Add and XRControlCollection.Remove methods enable you to add and remove individual controls from the collection. You can determine if the control is a member of the collection by passing the control into the XRControlCollection.Contains method. To get the index value of the control in the collection, pass this control into the XRControlCollection.IndexOf method.


The following example shows two methods that use the XRControlCollection.Add, XRControlCollection.Remove and XRControlCollection.Contains methods of the XRControlCollection class. The first method adds a control to the control collection of the XRPanel object at the specified location. The second method checks if the specified control belongs to the specified collection, and if it does, it removes the control from the collection.

using System.Drawing;
using DevExpress.XtraReports.UI;
// ...

public void AddControl(XRPanel panel, XRControl item, int x, int y) {
    // Add a control to the collection.

    // Set the control's location within the panel.
    item.Location = new Point(x, y);

public void RemoveControl(XRPanel panel, XRControl item) {
    // Check if the control belongs to the collection.

        // Remove the control from the collection.
