[color=Green]Hi,

Here's the solution to your problem...Read On...

For every data source that you want to bind with a Form, there exist a corresponding "CurrencyManager" object. This CurrencyManager object keeps track of the record as it points to the current item in the record list.

This CurrencyManager is derived from the BindingManagerBase class.

Also a Windows Form that is to be binded to the data source uses a BindingContext object, which is a windows form object.

Now the coding part is as follows:

Sub Page_Load()

Dim bm as BindingManagerBase
bm = BindingContext(DatasetName, TableName)
bm.Position = 0
End Sub

This bm's position if incremented, ie if we do something like

bm += 1

bm will point to the next record

The number of records can be identified by using bm.count which will surely return an integer.


Thats it...as simple as that...!!!

Revert back for any further clarifications...

This does not work in ASP.NET ...

First off, what code is being used to bind the form ... what version of ASP.NET is being used?

[color=Green]Hi,

The code that I provided in my last post works perfectly fine when creating a windows application.

Will be back with the navigation methodology in case of web applications very soon.
Inconvenience is regretted.
