Here is the VB code

Imports Infragistics.WebUI.UltraWebGrid

Imports System.Drawing

Imports System.Data.OleDb

Imports WebSamplesVB.WebSamplesVB

Partial Class _Default

Inherits System.Web.UI.Page

Protected oleDbConnection1 As System.Data.OleDb.OleDbConnection

Private contactsDataSet1 As New System.Data.DataSet

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not IsPostBack Then

' Create the template and add to it.

Dim template As ITemplatetemplate = Page.LoadTemplate("rowtemplate.ascx")

UltraWebGrid1.Bands(0).RowEditTemplate = template

' Add an extra column for a button to allow template editing

UltraWebGrid1.Columns.Insert(0, "Edit")

UltraWebGrid1.Columns(0).Type = ColumnType.Button

UltraWebGrid1.Columns(0).Width = New Unit(150)

Me.UltraWebGrid1.Columns(0).CellButtonStyle.BackColor = Color.FromArgb(204, 0, 0)

Me.DataBind()

End If

End Sub

Protected Sub UltraWebGrid1_DataBinding(ByVal sender As Object, ByVal e As System.EventArgs) Handles UltraWebGrid1.dataBinding

oleDbConnection1 = New OleDbConnection(Config.NorthwindMDBConnString)

Dim cmdCustomers As New OleDbDataAdapter("Select CustomerID,CompanyName,ContactName,Phone,Address from Customers where CustomerID < 'F'", oleDbConnection1)

cmdCustomers.Fill(contactsDataSet1, "Customers")

Me.UltraWebGrid1.DataSource = contactsDataSet1.Tables("Customers").DefaultView

End Sub

Protected Sub UltraWebGrid1_InitializeLayout(ByVal sender As Object, ByVal e As Infragistics.WebUI.UltraWebGrid.LayoutEventArgs) Handles UltraWebGrid1.InitializeLayout

Me.UltraWebGrid1.DisplayLayout.Bands(0).Columns(1).Header.Caption = "Customer ID"

Me.UltraWebGrid1.DisplayLayout.Bands(0).Columns(2).Header.Caption = "Company Name"

Me.UltraWebGrid1.DisplayLayout.Bands(0).Columns(4).Header.Caption = "Phone"

Me.UltraWebGrid1.DisplayLayout.Bands(0).Columns(5).Header.Caption = "Address"

End Sub

End Class

once the page loads i can click cell button to edit, but if i do a post back on the screen, click button(nothing on the code behind) and try to grid cell button click no template loads...

Note:

i also have user control page, but its no different than sample example row template (C:\Program Files\Infragistics\NetAdvantage 2006 Volume 2 CLR 2.0\ASP.NET\Samples\VB\WebGrid\RowTemplates\rowtemplate.ascx)
