Now i have a dataset (dataset.xsd the name is ds_BESR).

How i can my datas in the datagrid into this dataset ds_BESR?

Please help me...i need that. the reasen is my crystal report get the datas
from ds_BESR.
I have no idea how i can set the datas fom dataset ds to dataset ds_BESR.

Here my code...

You have a textfile with data?.
Then you (or someone) uses the xml schema definition file "dataset.xsd" to
transfer the data from the textfile to a datagrid?
And your problem is to transfer the data from the datagrid to a dataset
named ds_BESR?

Well, if the datagrid's datasource is a dataset you can obtain it with

ds_BESR = (DataSet)dataGrid1.DataSource;

If you have access to the original dataset you can use it's Copy() method
to copy the structure and content.

ds_BESR = ds.Copy();

this is ok........but ...

Now I get the database login screen...why?

here my code:

First input the datas from textfile into the datagrid and after input
ds_BESR => ds_BESR = ds.Copy(); :-)

After i open the crystal report..and get a screen database login

P: n/a
I'm afraid I do not know why you get the database login screen,
but seeing as you have the dataTable available before setting the datagrid
source, why use ds at all?
You could just add the MyTable to ds_BESR.
