RAB basics problemm: FP SDK, SignalBindingSource

jawojtek

Hello All.

I have a problemm which confuses me a lot. I need to use SignalBindingSource in basic FP SDK application. I do everything just like shown in the traning video but binding does not work. Need asistance.

Application consists of two buttons: one sets the signal and one resets it. There is a tpsLabel in order to automaticly refresh state of the signal which is manipulated. States of signal are changed but no data binding has place - tpsLabel does not change its state.

Application was tested in RS 5.11 and 5.11.01 also in real FlexPendant (RW 5.11). I use Visual Studio 2008 Pro (90-day Trial) and RAB 5.11.01 (tested also in 5.11). Systems had PC Int. and FP Int..

More I found: the data is correctly asinged to tps label:
   signalBindingSource1.Signals[0].Name - returns correct value (the name of the singnal).

It seems there is a problem with "refreshing" of tpsLabel1.Title. Maybe with bad compile process, wrong/incomplete resources or VS2008 itself.

If any more info needed - just write what do you need - I'll provide it.

Thanks,
Wojtek_PL

Try going into the advanced properties of your databindings and change the DataSourceUpdateMode to OnPropertyChanged from OnValidation and retry it.

I tried. It doesn't work. The problemm is that none value is assinged to the tpsLabel. A proper signal is added to the bindingObject but data is not "forwarded" to a tpsLabel.

If you are using the databindingsource through the designer it will only bind one UI property to the first item in the binding source, even though you can add multiple signal items. Try adding a second binding source for the second label.

The bindingsources work better with items that have a collection, like the Data Grid. However, if you study how the code is generated you can use the binding source programmatically and write code to handle the ListChanged or ItemChanged events of the binding source to update the UI.

 

Also, try using the text property not the title property of tpslabel.

Thanks for help.

The problem was with a tpsLabel itself - it was configured properly but it didn't work. DataGrid works fine, I'm glad

I don't know if it's a software whole in Visual Studio 2008 or in FP SDK. Please write if anyone has similar problem so we can locate the fault.

Thanks again.

Hi,

I used tpsLabel.Text property - there was a mistake in my first post.

I have done the exact same thing and I get the same problem.  I can see the signal name using
lblName.Text = signalBindingSource1.Signals[0].Name;

but it does not update on the labels that are bound to the source.

I am using VS2008 with the latest RW.

Hi,

 

Could you send me a simple test code and i will try to find out why it is not working.

 

The reason I am asking you for the sample code is to avoid generating one that might work ..

Carlos,

Here is a simple application.  It has a data grid that is bound to a signalbindingsource with two signals defined, DI_001 and DI_002.  The grid updates great but the label on the form does not.

Hi Shane,

 

The updated of signal inside RW 5.11 & 5.11.01 seems not to work. I could have a close look next week.

 

One thing I noticed is that it works in the next release, but I could confitm this until I test the actual release.

 

Have you triend rapid data or other type of signals?

Does anyone have an example of databinding for VS 2005 and RW5.10?  I've started to play with databinding and not getting very far with the manual.

 

Thanks,

Rick

Hi'

 

I still believe that its very important to get the signal/RapidDataBindingSource working on the TpsLabel. Please help on how this can be configured so that it works properly.

 

I am discoring the same problems descoverd above concerning the TpsLabel.

Hi Dezino,

 

Which RW version are you using?

Hi Dezino,

  Do have you the signalbinding working on for the datagrid? I've been playing more with the label with no luck.  What versions of software are you running?

 

Laterz,

Rick

Dezino

Hi

I am using the following software versions:

-RW5.11_0160

-RobotStudio 5.11

-VisualStudio2008

And Rick have both Signal/DataBinding working on a dataGrid, but no luck with the TpsLabel.

Hello Dezino,

  I have got the tpsLabel working.  Make sue that you go to the advance tab for the label and setup the databinding.  I've attached my application so you can an example.  I'm using RW5.10.2 and Visual Studio 2005.

Hi,

 

The SignalBinding wokrs OK, but he RapidBindingSource still have problems for getting the value of the RAPID variable.

 

The sample of SlickRick shows how to setup the binding of signals perfectly.

This is not working on Visual Studio2008 with RobotStudio5.11 and RobotWare5.11_0160

Any more suggestions might be helpful.

Thanks'

A workaround is to fetch the data you are interested on, and connect to the ValueChanged event for each of them. This is what the Binding mechanism do in principle.

 

In order to ahve a similiar performance, you will need to connect or disconnect the event mechanisms whenever your user interface is activate or not.

Anybody know if this is fixed in 5.12????
