As John mentioned, you can pass the DataTable to your Form when you instantiate it:

// You'll need an additional constructor in the MyForm class for this
MyForm oForm = new MYForm(dtTransDate);
if (oForm.ShowDialog() == DialogResult.OK)
{
    // put processing here
}

... or you can set it as a property:

// You'll need a "MyTable" Property in the MyForm class for this
MyForm oForm = new MYForm();
oForm.MyTable = dtTransDate;
if (oForm.ShowDialog() == DialogResult.OK)
{
    // put processing here
}
