CurrencyManager and BindingContext

cbm007 · August 10th, 2005, 05:22 AM

I'm kinda new to C# but i was wondering how come i couldn't manage to create a currency manager and binding context in program.cs. The error message that is displayed is this:
'System.Windows.Forms.BindingContext' is a 'type' but is used like a 'variable'.

All sql connections, data adapters, data sets etc. were working fine before adding the currency manager, however the only error is the one above.

I figure out you're trying to use the BindingContext object because you want to move around in your data source. Well, here goes how would you do that:

Every Form has a BindingContext object through which you can move around in your data source. All you need is to pass to this property (indexer in C# and default property in VB.NET) the data source and (optionally) a string identifying the data member within your data source. So, for example, if you have a DataSet object named northwindDataSet and it contains two tables named Customers and Orders and you want to move to the next record of the Customers table, write code like this:

Code:

// Move to next record
this.BindingContext[northwindDataSet, "Customers"].Position++;

// Move to previous record
this.BindingContext[northwindDataSet, "Customers"].Position--;

// Move to first record
this.BindingContext[northwindDataSet, "Customers"].Position = 0;

// Move to last record
this.BindingContext[northwindDataSet, "Customers"].Position = northwindDataSet.Tables["Customers"].Rows.Count - 1;

I hope this helps.
