GridControl.PaintEx Event

A DirectX-compatible method that replaces the standard Control.Paint method.

Namespace: DevExpress.XtraGrid

Assembly: DevExpress.XtraGrid.v25.1.dll

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

Declaration

C#

public event PaintExEventHandler PaintEx

VB.NET

Public Event PaintEx As PaintExEventHandler

Event Data

The PaintEx event's data class is DevExpress.XtraGrid.PaintExEventArgs.

Remarks

When handling the PaintEx event, use the DirectX-compatible API accessible through the e.Cache field rather then the standard e.Graphics API.

Example

This example draws a thick border around a grid cell under the mouse pointer.

View Example

C#

private void GridControl_PaintEx(object sender, DevExpress.XtraGrid.PaintExEventArgs e) {
    DrawHotTrackedCell(e.Cache);
}

private void DrawHotTrackedCell(GraphicsCache cache) {
    Rectangle bounds = GetCellBounds(HotTrackedCell);
    cache.DrawRectangle(new Pen(Brushes.Black, _BorderWidth), bounds);
}

VB.NET

Private Sub GridControl_PaintEx(ByVal sender As Object, ByVal e As DevExpress.XtraGrid.PaintExEventArgs)
    DrawHotTrackedCell(e.Cache)
End Sub

Private Sub DrawHotTrackedCell(ByVal cache As GraphicsCache)
    Dim bounds As Rectangle = GetCellBounds(HotTrackedCell)
    cache.DrawRectangle(New Pen(Brushes.Black, _BorderWidth), bounds)
End Sub
