in the first block of code you define
PersonBLL _localpers = null;

but in button1_click you do not use the _localpers but directly call the PersonBLL
private void button1_Click_1(object sender, EventArgs e)
{
try
{
_localdt = PersonBLL.GetAddressesFromPerson(textBoxBranchName.Text);

Shouldn't that be:
_localdt = _localpers.GetAddresFromPerson..... ?

Hi,

Update your code and see the result.

C#

_localdt = new DataTable("GeneralInfo");
_localdt = PersonBLL.GetAddressesFromPerson(textBoxBranchName.Text);
dataGridViewAddresses.DataSource = _localdt.Tables["Addresses"]; //Check it you are getting data into this line.

And if it is not working then use below line to bind data.

C#

dataGridViewAddresses.Grid.DataSource = localdt.Tables["Addresses"];
