hide link button and disable

Last Modified: 2012-08-14
I am using a telerik grid so that I can use detail tables.  What i am having trouble with is getting the value of a cell and depending on that value disabling the link button on the same row.  So currently whent he grid loads nothing is changed even though a couple link buttons should be hidden, but when I click on one and it posts back all the link butons disapear.  What am I doing wrong here and why does it not work on grid load.

 Protected Sub myIssueGrid_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles myIssueGrid.ItemDataBound
        If e.Item.OwnerTableView.Name = "myIssueGrid" Then
            If TypeOf e.Item Is GridDataItem Then
                Dim Item As GridDataItem = DirectCast(e.Item, GridDataItem)
                Dim lbl As TableCell = Item("strTransaction")
                Dim Trans As LinkButton = DirectCast(Item.FindControl("lnkTransfer"), LinkButton)
                Dim tType As Label = DirectCast(Item.FindControl("lbltranstype"), Label)
                Dim image As Image = DirectCast(Item.FindControl("imgReturn"), Image)
                Dim type As Integer

                Type = Convert.ToInt32(tType.Text)

                If type = 6 Or tType.Text = "TRANSFER" Then   Either one of these should work
                    Trans.Enabled = False
                    image.Visible = False
                End If
            End If
        End If
    End Sub

" link butons disapear" but in the code it says disable it, not hide it...

or I could not get the issue...



I am just trying to get it to do something.  Right not it does nto even disable itself.  I can still click on it and it still shows my popup that comes up, so its not even getting disabled.

I have tried both, it seemd to not even get into the main grid.  Something interesting though is I put the same code to the detailsTable grid that is a sub grid and the code works just fine.  It is really wierd, I made sure all my names where right and looked at case sensitivity becuase sometimes telerik controls can be case sensitive.

  If e.Item.OwnerTableView.Name = "myReIssueGrid" Then
            If TypeOf e.Item Is Telerik.Web.UI.GridDataItem Then
                Dim item As Telerik.Web.UI.GridDataItem = DirectCast(e.Item, Telerik.Web.UI.GridDataItem)
                Dim cancel As LinkButton = DirectCast(item.FindControl("lnkCancel"), LinkButton)
                Dim Accept As LinkButton = DirectCast(item.FindControl("lnkAccept"), LinkButton)
                Dim lbl As TableCell = item("strTransaction")
                Dim Trans As Label = DirectCast(item.FindControl("lbltrans"), Label)
                Dim TransTo As Integer

                TransTo = Convert.ToInt32(Trans.Text)

                If lbl.Text = "TRANSFER" Then
                    If TransTo = Convert.ToInt32(HFPersId.Value) Then
                        Accept.Enabled = False
                        Accept.Text = Nothing
                    End If
                End If
            End If
        End If

you should debug your code and see if it is working as intended...

put a break point on first line

>>>> BP here >>> If e.Item.OwnerTableView.Name = "myIssueGrid" Then

and see whats is wrong...



I just get a yello bar and it says return booleen but I don't see a value in there.
