Hello, Marcio,
GridViewImageColumn displays read-only images for database columns of Image data type (OLE container or BLOB).
I have prepared a sample code snippet demonstrating how to display a SVG image inside a CellElement by specifying its SvgImage property:
Sub New()
InitializeComponent()
RadControl.EnableSvgImages = True
Dim colIdiomaOriginalSvg As New GridViewImageColumn("IdiomaOriginalFoto")
colIdiomaOriginalSvg.DataType = GetType(RadSvgImage)
If Me.RadGridView1.Columns.Count = 0 Then
Me.RadGridView1.MasterTemplate.Columns.Add(colIdiomaOriginalSvg)
End If
AddHandler Me.RadGridView1.CellFormatting, AddressOf RadGridView1_CellFormatting
Dim fotoDtpSvg As RadSvgImage = RadSvgImage.FromFile("..\..\computer.svg")
Me.RadGridView1.Rows.Add(fotoDtpSvg)
fotoDtpSvg = RadSvgImage.FromFile("..\..\atom.svg")
Me.RadGridView1.Rows.Add(fotoDtpSvg)
Me.RadGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill
Me.RadGridView1.TableElement.RowHeight = 200
Me.RadGridView1.AllowAddNewRow = False
End Sub
Private Sub RadGridView1_CellFormatting(sender As Object, e As CellFormattingEventArgs)
If e.Column.Name = "IdiomaOriginalFoto" Then
e.CellElement.SvgImage = e.CellElement.Value
End If
End SubMore information about the vector images is available in the following help article:
