[Solved] RadToolTip in RadGrid

[Eric]

I am trying to add the radtooltip into an item template of a dynamically created table.  I have the follwing code

  Public Sub InstantiateIn(ByVal container As System.Web.UI.Control) Implements ITemplate.InstantiateIn
            gridLabel = New Label()
            AddHandler gridLabel.DataBinding, AddressOf gridLabel_DataBinding
            gridCheck = New CheckBox()
            AddHandler gridCheck.DataBinding, AddressOf GridCheck_DataBinding
            gridCheck.Enabled = True

            container.Controls.Add(gridCheck)
            container.Controls.Add(gridLabel)

        End Sub

        Sub GridCheck_DataBinding(ByVal sender As Object, ByVal e As EventArgs)
            Dim cBox As CheckBox = DirectCast(sender, CheckBox)
            Dim container As GridDataItem = DirectCast(cBox.NamingContainer, GridDataItem)
            If DirectCast(container.DataItem, DataRowView)("ContractObjectiveID").ToString <> "0" Then
                cBox.Checked = True
            Else
                cBox.Checked = False
            End If
        End Sub

        Public Sub gridLabel_DataBinding(ByVal sender As Object, ByVal e As EventArgs)
            Dim l As Label = DirectCast(sender, Label)
            Dim container As GridDataItem = DirectCast(l.NamingContainer, GridDataItem)
            l.ID = "Label1"
            l.Text = (DirectCast(container.DataItem, DataRowView))("ObjectiveCode").ToString()

            Dim t As Telerik.Web.UI.RadToolTip = New Telerik.Web.UI.RadToolTip
            t.Text = (DirectCast(container.DataItem, DataRowView))("Description").ToString()
            t.Position = ToolTipPosition.MiddleRight
            t.RelativeTo = ToolTipRelativeDisplay.Element
            t.TargetControlID = l.ID

        End Sub

I do not get an error but at the same time I don not get the tooltip to show.  I need to be able to change the grid based on a field in the database.  I have the grid created but need to add the tooltip.  Is this possible?

Hello Eric,

In my opinion you forgot to add the RadToolTip to the Label's controls collection.

What exactly do you mean by  "add the RadToolTip to the Label's controls collection"?  When I tried l.controls.add(t) the lables no longer displays

Hello Eric,

Actually I meant the container's collection, and not the label's - apologies for the mistake.
For a convenience I created a sample which illustrates this approach.

Hope it will be suitable for your scenario.
