This code excerpt demonstrates how to upload an image from within a grid cell. The controls in the templatefield/EditItemTemplate, such as, FileUpload controls, textbox controls, or checkboxes can not be access directly. An ASP:Button can be mapped to the the UploadImage_Click event on Click. The Grid row can be accessed by the EditIndex attribute and the FindControl method of the row Gridview used to return a typecasted of the control. Now your in business, the file can be uploaded using the FileUpload, SaveAs method.

<script runat="server">

    Protected Sub UploadImage_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim strFileName As String
        Dim oPictureFileUpload As FileUpload = Nothing
        Dim oInputImage_Path As TextBox = Nothing
        Dim oImgProduct As Image = Nothing
        Dim row As GridViewRow = Nothing
        
        If dgProduct.EditIndex <> -1 Then
            row = dgProduct.Rows(dgProduct.EditIndex)
            oPictureFileUpload = CType(row.FindControl("ImageFileUpload"), FileUpload)
            oInputImage_Path = CType(row.FindControl("txtInputImage_Path"), TextBox)
            strFileName = oPictureFileUpload.FileName
            Dim c As String = System.IO.Path.GetFileName(strFileName)

            Try
                oPictureFileUpload.PostedFile.SaveAs(Server.MapPath("~\") & c)
            Catch Exp As Exception
                'Span1.InnerHtml = "An Error occured. Please check the attached  file"
            End Try
            oInputImage_Path.Text = strFileName
        End If
    End Sub
