BindingSource Filter issue in UserControl - Odd Problem.

Hello All,

I have looked all over the internet and have not found a solution to the problem I am having.

Basically I have a datasource bound to some textboxes in a usercontroller. I am trying to set the datasource filter in the usercontrol. I am trying to trigger this from the main form by calling a public method in the user control. When I call the method from the main form, the method runs but nothing happens after the filter has been set. When I set the filter from a button in the usercontrol everything works fine. I have tried using documentsBindingSource.ResetBindings(false); but that doesn't help either. I am not sure what I am doing wrong. Can someone help?

Thanks in advance.

namespace qDoc.Controls
{
    public partial class FileDetails : UserControl
    {
        public FileDetails()
        {
            InitializeComponent();
            documentsTableAdapter.Fill(dsDocumentDetails.Documents);
        }
        public void LoadDocument()
        {
            documentsBindingSource.Filter = "DocID=303"; // This is called from parent form. Nothing happens after it's called.
        }

        private void btnTest_Click(object sender, EventArgs e)
        {
            documentsBindingSource.Filter = "DocID=303"; // This works and textboxes are updated.
        }
    }
}

namespace qDoc
{
    public partial class Form1 : Form
    {
        ...

        private void dgFileList_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            int col = dgFileList.CurrentCell.ColumnIndex;
            int row = dgFileList.CurrentCell.RowIndex;

            switch(col)
            {
                case 0:
                    MessageBox.Show("Edit DocID : " + dgFileList.Rows[row].Cells[2].Value.ToString());
                    break;
                case 1:
                    FileDetails fd = new FileDetails();
                    fd.LoadDocument(); // Calling method in UserControl.
                    break;
                default:
                    break;
            }
        }
    }
