Hi,
First you need to create a TemplateColumn and add it to the datagrid.
Dim tmpCol As TemplateColumn
tmpCol = New TemplateColumn
DataGrid1.Columns.Add(tmpCol)
Then on the DataGrids itemBound event you have to add an image to the cell.
Private Sub DataGrid1_ItemDataBound(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.DataGridItemEventArgs) Handles
DataGrid1.ItemDataBound
Dim imgTemp As New System.Web.UI.HtmlControls.HtmlImage
imgTemp.Src = "..."(Path of the image)
e.Item.Cells(0).Controls.Add(imgTemp)
End Sub
PS:I have given a simplest way of getting an image column in a datagrid.
