Display multiple images in a grid cell

To display multiple Images in a cell, you need to handle the CellDrawn Event. In the following code example, the image is attained from the ImageList that has the collection of images. In the CellDrawn event handler, the images are drawn in the cell by using the bounds of the rectangle.

C#

//Sets the cellType as Image
this.gridControl1[3, 3].CellType = GridCellTypeName.Image;
Bitmap bmp1 = SystemIcons.Exclamation.ToBitmap();
Bitmap bmp2 = SystemIcons.Question.ToBitmap();
Bitmap bmp3 = SystemIcons.Shield.ToBitmap();
//Adds the bitmaps to the image list
images.Images.Add(bmp1);
images.Images.Add(bmp2);
images.Images.Add(bmp3);
//Hooks the CellDrawn event in Form_Load to add images
this.gridControl1.CellDrawn += gridControl1_CellDrawn;  
void gridControl1_CellDrawn(object sender, GridDrawCellEventArgs e)
{
    if (e.RowIndex ==3 && e.ColIndex==3  )
    {
         Rectangle rect = new Rectangle(e.Bounds.Location, images.ImageSize);
         rect.Intersect(e.Bounds);
         for (int i = 0; i < this.images.Images.Count; ++i)
         {
              GridStaticCellRenderer.DrawImage(e.Graphics, this.images, i, rect, false);
              rect.Offset(this.images.ImageSize.Width + 1, 0);
         }
    }
}

 

VB

'Sets the cellType as Image
Private Me.gridControl1(3, 3).CellType = GridCellTypeName.Image
Private bmp1 As Bitmap = SystemIcons.Exclamation.ToBitmap()
Private bmp2 As Bitmap = SystemIcons.Question.ToBitmap()
Private bmp3 As Bitmap = SystemIcons.Shield.ToBitmap()
'Adds the bitmaps to the image list
images.Images.Add(bmp1)
images.Images.Add(bmp2)
images.Images.Add(bmp3)
'Hooks the CellDrawn event in Form_Load to add images
Me.gridControl1.CellDrawn += gridControl1_CellDrawn
Private Sub gridControl1_CellDrawn(ByVal sender As Object, ByVal e As GridDrawCellEventArgs)     
     If e.RowIndex =3 AndAlso e.ColIndex=3 Then
          Dim rect As New Rectangle(e.Bounds.Location, images.ImageSize)
          rect.Intersect(e.Bounds)
          For i As Integer = 0 To Me.images.Images.Count - 1
               GridStaticCellRenderer.DrawImage(e.Graphics, Me.images, i, rect, False)
               rect.Offset(Me.images.ImageSize.Width + 1, 0)
          Next i
     End If
End Sub
