GridView.RowCount Property

Returns the number of visible Grid records.

Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v23.2.dll

NuGet Packages: DevExpress.Win.Grid, DevExpress.Win.Navigation

Declaration

C#

public override int RowCount { get; }

VB.NET

Public Overrides ReadOnly Property RowCount As Integer

Property Value

Type	Description
Int32	The number of visible Grid rows.

Remarks

This property overrides the BaseView.RowCount property to increment its value in these cases:

• the new item row is shown at the bottom (the View’s GridOptionsView.NewItemRowPosition property is set to the NewItemRowPosition.Bottom value);
• the new item row is hidden (the View’s GridOptionsView.NewItemRowPosition property is set to the NewItemRowPosition.None value), a user adds a new row and starts editing its value.

Note

Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the RowCount member must not be invoked for these Views. The RowCount member can only be used with Views that display real data within the Grid Control. Use the following methods to access these Views with which an end user interacts at runtime.

• GridControl.MainView - returns the top most View in a grid;
• GridControl.FocusedView - returns the focused View;
• GridControl.DefaultView - returns the currently maximized View;
• the sender parameter of View specific events;
• GridView.GetDetailView - returns a detail clone View for a specific master row.

The code sample below illustrates how to paste a clipboard value into all cells under the “TargetColumn” column.

C#

private void gridView_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e) {
    if (e.Control && e.KeyCode == System.Windows.Forms.Keys.V) {
        var text = Clipboard.GetText();
        for (int i = 0; i < gridView.RowCount; i++) {
            if (gridView.IsDataRow(i)) {
                this.gridView.SetRowCellValue(i, "TargetColumn", text);
                e.Handled = true;
            }
        }
    }
}

VB.NET

'INSTANT VB NOTE: This code snippet uses implicit typing. You will need to set 'Option Infer On' in the VB file or set 'Option Infer' at the project level.

Private Sub gridView_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs)
    If e.Control AndAlso e.KeyCode = System.Windows.Forms.Keys.V Then
        Dim text = Clipboard.GetText()
        For i As Integer = 0 To gridView.RowCount - 1
            If gridView.IsDataRow(i) Then
                Me.gridView.SetRowCellValue(i, "TargetColumn", text)
                e.Handled = True
            End If
        Next i
    End If
End Sub
