Hi Handy

Nothing happens! Display is already set to none!

Maybe the wrong Element?

Hi Dicky

Thanks for your answer.

I found out why it does not work.

It's the same problem as I have described in this thread: [IS-C554F370-167F-4097-9B9E-10502BBF3264]

It works only, when the column name of the primary- and foreign keys are identical!

Thanks for a quick fix to the problem...

Hi Gordon

It's true, it's possible to add a single record.

But try to add more then one record. I get the Message The pending changes already contain a record with key ''.

Hi Gordon

I am using SQL Server 2008.

I have also attached a scriptfile for creating tables. You must only insert some data.

Best regards

Hi James

Sorry, I was confused about DataMember="DataSetA".

At the second reading I've noticed that you mean the DataTable...

Here is the complete and functional code:

private DataSet ds;

protected void Page_Load(object sender, EventArgs e)
{
    ds = GetData();
}

protected void grd1_PrepareDataBinding(object sender, DataSourceEventArgs e)
{
    if (!Page.IsPostBack)
    {
        grd1.ClearCachedDataSource();
        grd1.RetrieveStructure();
    }
}

protected void grd1_InitializeDataSource(object sender, DataSourceEventArgs e)
{
    grd1.DataMember = "<DataTable1>";
    grd1.RootTable.DataMember = "<DataTable1>";
    e.DataSource = ds;
}

protected void grd2_PrepareDataBinding(object sender, DataSourceEventArgs e)
{
    if (!Page.IsPostBack)
    {
        grd2.ClearCachedDataSource();
        grd2.RetrieveStructure();
    }
}

protected void grd2_InitializeDataSource(object sender, DataSourceEventArgs e)
{
    grd2.DataMember = "<DataTable2>";
    grd2.RootTable.DataMember = "<DataTable2>";
    e.DataSource = ds;
}

Thank you, James!

Michael
