Hello. I need to get data into dataview (to loop through the rows in the dataview) from my dataset(after making some changing some records:insert, update, insert).
So i need an answer on these two questions:
Can i get data from dataadapter into dataview ? Or i have to get data from dataadapter into dataset then from dataset to dataview(If it's possible)

I have tried something like this:

VB

Dim strconnection As String = "Data Source=EASMAR-PC;Initial Catalog=Database Connection;Integrated Security=True;"
        _cn = New SqlConnection(strconnection)
        _cn.Open()
        cmd.Connection = _cn
        'Get the data from database into dataadapter
        _DataAdapter.SelectCommand = New SqlCommand("SELECT * FROM tblCustomer", _cn)
        'Fill the dataset from dataadapter
        _DataAdapter.Fill(_DataSet)
        Dim dt As New DataTable
        dt = _DataSet.Tables("tblCustomer")
        'dt contain nothing!!
        '_DataAdapter.Fill(dt)

        Debug.WriteLine(dt.Rows.Count.ToString)

And i am getting this error:

VB

Object reference not set to an instance of an object.

On this line:

VB

Debug.WriteLine(dt.Rows.Count.ToString)

After "_DataAdapter.Fill(_DataSet)" how many tables are present in _DataSet.Tables ?

There may be 2 cases
1.The table tblCustomer is not there in dataset
2.There is no table in the dataset

Please check the dataset while debugging and let me know.
Thanks,
Sibasis

I only have one table. I replaced the name of the table by its index. I don't think it's the problem.

VB

Dim dt As New DataTable
dt = _DataSet.Tables(0)

But it worked.
now i'm getting my data from dataset.
I checked the dataset, it contains my table.
And the previous error is gone. I am going to continue my idea. Hope it works.
Thank you for your response.
