ColumnView.CellValueChanged Event

Fires immediately after a cell’s value has been changed.

Namespace: DevExpress.XtraGrid.Views.Base

Assembly: DevExpress.XtraGrid.v18.1.dll

Declaration

C#

[DXCategory("Property Changed")]
public event CellValueChangedEventHandler CellValueChanged

VB.NET

<DXCategory("Property Changed")>
Public Event CellValueChanged As CellValueChangedEventHandler

Event Data

The CellValueChanged event's data class is CellValueChangedEventArgs. The following properties provide information specific to this event:

Property	Description
Column	Gets the column that contains the processed cell.
RowHandle	Gets the handle of the row that contains the processed cell.
Value	Gets the current cell value.

Remarks

The CellValueChanged event fires in response to a cell’s value being changed. The list below gives the possible reasons for this event being raised:

• An end-user has closed an in-place editor after changing the editor’s value.
• A cell’s value has been changed using the methods provided by Views. For instance, the ColumnView.SetRowCellValue method can be used for this purpose.

The event doesn’t fire when a cell’s value is changed using the methods provided by the data source.

Example

The following sample code handles the ColumnView.CellValueChanged event to update the FullName column value after the FirstName column value has been changed.

C#

using DevExpress.XtraGrid.Views.Base;
using DevExpress.XtraGrid.Views.BandedGrid;

private void bandedGridView1_CellValueChanged(object sender, CellValueChangedEventArgs e) {
    BandedGridView view = sender as BandedGridView;
    if (view == null) return;
    if (e.Column.Caption != "FirstName") return;
    string cellValue = e.Value.ToString() + " " + view.GetRowCellValue(e.RowHandle, view.Columns["LastName"]).ToString();
    view.SetRowCellValue(e.RowHandle, view.Columns["FullName"], cellValue);
}

VB.NET

Imports DevExpress.XtraGrid.Views.Base
Imports DevExpress.XtraGrid.Views.BandedGrid

Private Sub BandedGridView1_CellValueChanged(sender As Object, e As DevExpress.XtraGrid.Views.Base.CellValueChangedEventArgs) Handles BandedGridView1.CellValueChanged
    Dim view As BandedGridView = sender
    If view Is Nothing Then
        Return
    End If
    If e.Column.Caption <> "FirstName" Then
        Return
    End If
    Dim cellValue As String = e.Value.ToString() + " " + view.GetRowCellValue(e.RowHandle, view.Columns("LastName")).ToString()
    view.SetRowCellValue(e.RowHandle, view.Columns("FullName"), cellValue)
End Sub
