I am trying to dynamically create a context menu and set it's ContextControlID to a dynamically created textbox. The problem is right-clicking the textbox does not display the menu. Can you look at my code and let me know what I'm doing wrong. The page is a context for a master page. I have tested it on a standalone page with no master page and it works fine.
Code: Visual Basic.NET
For day_ctr As Integer = 0 To 6
cell = New TableCell
With cell
.Attributes.Add("onmouseover", "updateStatus('Right-click time cell for menu...')")
.Attributes.Add("onmouseout", "updateStatus('')")
End With
Dim txt As New TextBox
With txt
.ID = Guid.NewGuid.toString
.Width = New Web.UI.WebControls.Unit(50, UnitType.Pixel)
.Attributes.Add("onblur", "validateInput(this)")
.Attributes.Add("onmouseover", "updateStatus('Right-click time cell for menu...')")
.Attributes.Add("onmouseout", "updateStatus('')")
End With
Dim mnu As New EO.Web.ContextMenu
With mnu
.Width = New Web.UI.WebControls.Unit(150, UnitType.Pixel)
.ContextControlID = txt.ClientID
.BackColor = Drawing.Color.DarkOliveGreen
End With
Dim mnu_item As New EO.Web.MenuItem
With mnu_item
.Text.Html = "Option 1"
End With
mnu.Items.Add(mnu_item)
With cell
.Width = New Web.UI.WebControls.Unit(50, UnitType.Pixel)
.BorderStyle = BorderStyle.Solid
.BorderColor = Drawing.Color.DarkOliveGreen
.BorderWidth = New Web.UI.WebControls.Unit(1, UnitType.Pixel)
.Controls.Add(txt)
.Controls.Add(mnu)
End With
row.Cells.Add(cell)
Next

Hi,
Your code looks fine to us. Can you isolate the problem into a standalone test page so that we can run it here and see the problem?
Thanks!

This is the standalone that works
Code: Visual Basic.NET
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
Dim row As New TableRow
Dim cell As New TableCell
cell.ID = Guid.NewGuid.ToString
cell.Width = 100
cell.BorderStyle = BorderStyle.Solid
cell.BorderWidth = 1
cell.BorderColor = Drawing.Color.DarkBlue
Dim txt As New TextBox
txt.ID = Guid.NewGuid.ToString
Dim mnu As New EO.Web.ContextMenu
mnu.ContextControlID = txt.ID
Dim mi As New EO.Web.MenuItem
mi.Text.Html = "Option 1"
mnu.Items.Add(mi)
cell.Controls.Add(txt)
cell.Controls.Add(mnu)
row.Cells.Add(cell)
Table1.Rows.Add(row)
End Sub

This is the one where it dosent work Code behind
Code: Visual Basic.NET
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
Dim row As New TableRow
Dim cell As New TableCell
cell.ID = Guid.NewGuid.ToString
cell.Width = 100
cell.BorderStyle = BorderStyle.Solid
cell.BorderWidth = 1
cell.BorderColor = Drawing.Color.DarkBlue
Dim txt As New TextBox
txt.ID = Guid.NewGuid.ToString
Dim mnu As New EO.Web.ContextMenu
mnu.ContextControlID = txt.ID
Dim mi As New EO.Web.MenuItem
mi.Text.Html = "Option 1"
mnu.Items.Add(mi)
cell.Controls.Add(txt)
cell.Controls.Add(mnu)
row.Cells.Add(cell)
Table1.Rows.Add(row)
End Sub

Hi,
Make sure you call this:
cell.Controls.Add(txt)
Before calling:
mnu.ContextControlID = txt.ClientID
Also note it's txt.ClientID, not txt.ID.
Thanks!

I had to set the ContextControlID once the parent control had been placed on the form so for any else who might need and example I used somethng this. Thanks to the folks at EO...
Code: Visual Basic.NET
For Each row As TableRow In Table1.Rows
For Each cell As TableCell In row.Cells
Dim mnu As EO.Web.ContextMenu = CType(cell.Controls(0), EO.Web.ContextMenu)
mnu.ContextControlID = cell.ClientID
Next
Next

Yes. That will work too. The key is the control has to be already on the page. Otherwise ClientID will be wrong.
Thanks!
