Group: StrataFrame Users Posts: 153, Visits: 1.2K	Hello, I have a problem with binding (I suppose) I have ComboA and ComboB binded to a BO When I change ComboA value, ComboB can change to another value The problem is that if I change comboB value, comboA value change to the previus value //when combo A (uxIdTipoContribuyente) change I have to change combo B (uxIdTipoDocumento) on some condition if needed private void uxIdTipoContribuyente_SelectedValueChanged(object sender, EventArgs e) { SetControlDocumento((int)uxIdTipoContribuyente.SelectedValue); } //if I have to change the comboB value, I call a method that change that value to an known value private void SetControlDocumento(int idTipoContribuyente) { // this says me if the comboA value have to change comboB value... if (BO.Dic.TiposContribuyentesBO.EsCuitObligatorio(idTipoContribuyente)) { //here I call a user control method that change his combobox control SelectedValue to an known value documentoControl.SetTipoDocumento(TiposDocumentosEnum.CUIT); } } // Documentcontrol is a inherited strataframe user control with a combo and a textbox... this method change the selected value of the combo Documentcontrol.SetTipoDocumento (TiposDocumentosEnum tipoDocumentoId) { uxIdTipoDocumento.SelectedValue = (int)tipoDocumentoId; //uxIdTipoDocumento.EditValue = tipoDocumentoId.ToString(); } // The problem is that when SelectedValue on uxIdtipoDocumento is called, the BO's strataframe businesslayer call the event CurrentView_ListChanged that have this code: If (Not Me._AreChangedEventsPaused) Then loDelegate.Invoke(Me.GetPropertyDescriptor(e.PropertyDescriptor.Name), EventArgs.Empty) ... // this code seems to refresh the value of the datasource and I loose the value that I setted on the combobox A I have to do it at BO level? to do this I have to set BO's properties on BOM "Property changing events" to single for all / unique for each property and alter values here? or I have to control the "ChangedEventPaused"? (can I?) thanks in advance for the help that can bring to me on this problem Edited 12 Years Ago by Fabian R Silva, -

I can have future problems using this PauseChangedEvent property, what cares I have to keep present when pausing changed events? Can I do this change of a property from another property at BO level?(enabling changed properties for this BO)? it's better because it keep defaults/validate logic separately from the UI? thanks! Code that seems to works: ------------------------ public void SetTipoDocumento (TiposDocumentosEnum tipoDocumentoId) { ((BusinessLayer)BusinessObject).PauseChangedEvents(); uxIdTipoDocumento.SelectedValue = (int)tipoDocumentoId; ((BusinessLayer)BusinessObject).ResumeChangedEvents(); } Edited 12 Years Ago by Fabian R Silva, -

I use the BOM Property Single Event and handle that with a Select Case and update the BO properties instead of the controls in the UI, by updating the BO properties, the UI controls would be updated automatically.
