Greetings,
I have a vb.net application, which has a textbox (textbox1). I am trying to use the databindings of this textbox to bind it to an entity, created with llblgen.
The data is shown in the textbox normally, but when I try to change this data, is jumps back to the initial data when I change focus to another object.
I am using the following code:
Private Sub setDataLoggerBindings()
' DataLogger bindings
With frmEquipment.GlobalForm
If .selEntity.DataLogger_.Count > 0 Then
Me.TextBox1.DataBindings.Clear()
Dim b As New Binding("Text", .selEntity.DataLogger_(0), "MachineNumber")
Me.Textbox1.DataBindings.Add(b)
End If
End With
End Sub
Is there some setting I need to adjust to be able to get the value to the entity?
I am using the following setup:
version:
LLBLGen Pro 2.6 Final (October 6th, 2008 ) (no specific buildnr is mentioned)
runTime library version:
2.6.9.116
Template group:
