Hi,

I have to set the GridColumn dynamically, when the form loads. I am setting one of the GridColumns to show the bitmaps by setting
DataGridView.ValueType = typeof(Bitmap)
and it always shows System.Drawing.Bitmap as text and never draws the bitmap.
I even tried
DataGridViewColumn dgvc = new DataGridViewImageColumn(false);
But that also didn't work.
I know, that I can override the cell paint method and draw bitmaps there. But, i am really interested in trying the inherent features that DataGridView has before overriding the methods.

Thanks,

Hi

The following code example demonstrates how to extract an icon from an embedded resource and convert it to a bitmap for display in every cell of an image column. For another example that replaces textual cell values with corresponding images, see How to: Customize Data Formatting in the Windows Forms DataGridView Control.

Public Sub CreateGraphicsColumn()

Dim treeIcon As New Icon(Me.GetType(), "tree.ico")

Dim iconColumn As New DataGridViewImageColumn()

With iconColumn

.Image = treeIcon.ToBitmap()

.Name = "Tree"

.HeaderText = "Nice tree"

End With

dataGridView1.Columns.Insert(2, iconColumn)

End Sub

And here is another article about how to: Work with Image Columns in the Windows Forms DataGridView Control
