Adding record to an empty dataset and databinding to a form

[xai999]

I have this form wich contians a dataset that can be empty in certain conditions. When I add the first record to this dataset it doesn't show this record in the bound controls on the form (I know for shure, cause the values differ from the values initialized in the new record).

I tried calling the refresh on the currencymanager like this

(this.BindingContext[ periodDataSet1, "Period" ] as CurrencyManager).Refresh();

But it results in the following exception:
"DataBinding could not find a row in the list that is suitable for all bindings"

I've also tried calling SuspendBinding and then ResumeBinding, but then the resumebinding also causes this exception.

And then silence smacks right in there...
... And it is loud!

Dear xai999,
As far as i could understand the situation, u have a dataset bound to a control and not all times this dataset holds data.
I imagine it like this:
1. Check ur condition to fill the dataset and (fill it if true) (Leave it empty if false)
2. Bind the dataset to the control

I hope i could understand it

Sorry for the scares information, but my code is spread throughout several classes.

Fill is called everytime the form opens, also when there is no data.

You're saying I shouldn't call fill when there is no data?

I've made a small testprogram, but in there it does work, so there's a problem with my code somewhere.
Will keep you informed.
