GridView.RowCellClick Event

Fires when a user clicks a data cell. If data is editable and the ColumnViewOptionsBehavior.EditorShowMode property equals MouseDown (or Default, if multiple row selection is disabled), the event is suppressed.

Namespace:DevExpress.XtraGrid.Views.Grid
Assembly:DevExpress.XtraGrid.v19.1.dll

Syntax

C#: public event RowCellClickEventHandler RowCellClick

VB: event Public RowCellClick As RowCellClickEventHandler

Event Data

The event handler receives an argument of type RowCellClickEventArgs containing data related to this event.

The following RowCellClickEventArgs properties provide information specific to this event.

Property	Description
Button	Gets which mouse button was pressed.
CellValue	Gets the edit value of the clicked cell.
Clicks	Gets the number of times the mouse button was pressed and released.
Column	Gets the column that contains the clicked cell.
Delta	Gets a signed count of the number of detents the mouse wheel has rotated. A detent is one notch of the mouse wheel.
Handled	Gets or sets a value specifying whether an event has been handled.
HitInfo	Gets an object that identifies the clicked element.
IsHMouseWheel	This member supports the internal infrastructure, and is not intended to be used directly from your code.
IsMouseEvent	Gets whether these event arguments provide data for the MouseUp, MouseDown, and MouseMove events.
Location	Gets the location of the mouse during the generating mouse event.
RowHandle	Gets the handle of the clicked row.
X	Gets the x-coordinate of the mouse during the generating mouse event.
Y	Gets the y-coordinate of the mouse during the generating mouse event.

Remarks

The RowCellClick event does not fire when a user clicks on a row cell if Grid data is editable and the ColumnViewOptionsBehavior.EditorShowMode property is set to MouseDown (or to Default, if multiple row selection is disabled).

The HitInfo parameter is not initialized when this event fires. Use the BaseView.CalcHitInfo method to get a HitInfo object.

Example

In this example, the Data Grid is in non-editable mode (does not invoke cell editors when users click them). Cells under the "State" column cycle through all "ObjectState" enumerator values when a user clicks these cells.

using System.Collections.Generic;
using System.Windows.Forms;
using DevExpress.XtraGrid;
using DevExpress.XtraGrid.Views.Grid;

namespace DXApplication3
{
    public partial class Form1 : DevExpress.XtraEditors.XtraForm {
        public Form1() {
            InitializeComponent();
            //add Data Grid
            GridControl gridControl = new GridControl { Parent = this, Dock = DockStyle.Fill };
GridView gridView = new GridView();
            gridView.OptionsBehavior.Editable = false;
            gridControl.MainView = gridView;
            //bind to sample data
            List<SomeObject> dataSource = new List<SomeObject>();
            for (int i = 0; i < 4; i++)
                dataSource.Add(new SomeObject { Name = string.Format("Object{0}", i), State = (ObjectState)i });
            gridControl.DataSource = dataSource;

            gridView.RowCellClick += gridView_RowCellClick;
        }

        //when a user clicks any "State" column cell, the cell should change its value
        void gridView_RowCellClick(object sender, RowCellClickEventArgs e) {
            if (e.Column.FieldName == "State") {
                ObjectState state = (ObjectState)e.CellValue;
                ObjectState newState;
                switch (state) {
                    case ObjectState.Normal:
                        newState = ObjectState.Selected;
                        break;
                    case ObjectState.Selected:
                        newState = ObjectState.Highlighted;
                        break;
                    case ObjectState.Highlighted:
                        newState = ObjectState.Hovered;
                        break;
                    default:
                        newState = ObjectState.Normal;
                        break;
                }
                GridView view = sender as GridView;
                view.SetRowCellValue(e.RowHandle, e.Column, newState);
            }
        }

        //sample data entity
        public class SomeObject {
            public string Name { get; set; }
            public ObjectState State { get; set; }
        }

        //available values for the "State" column cells
        public enum ObjectState {
            Normal,
            Selected,
            Highlighted,
            Hovered
        }
    }
}
