C# WinForms Data Binding on Check Box Help Needed

My check box is not causing the binding source to change when checked.

I have a checkbox that is bound to an SQL table (defined as TinyInt) like so:

        // 
        // overrideCheckBox
        // 
        this.overrideCheckBox.CausesValidation = false;
        this.overrideCheckBox.DataBindings.Add(new                                  System.Windows.Forms.Binding("CheckState", this.ProcessingBindingSource, "rtoverride", true));
        this.overrideCheckBox.Location = new System.Drawing.Point(354, 378);
        this.overrideCheckBox.Name = "overrideCheckBox";
        this.overrideCheckBox.Size = new System.Drawing.Size(104, 24);
        this.overrideCheckBox.TabIndex = 70;
        this.overrideCheckBox.Text = "Override";
        this.overrideCheckBox.UseVisualStyleBackColor = true;
        this.overrideCheckBox.Visible = false;

It's defined as System.Byte in the table adapter.

I'm using this code to save:

        this.ProcessingBindingSource.EndEdit();
        this.ProcessingTableAdapter.Update(rMSDataSet);
        myDataSet.AcceptChanges();

Every other field saves except my checkbox. I checked my binding source back to my table and everything seems correct except ProcessingBindingSource -> current row -> rtoverride hasn't changed to reflect the new value of checked = 1.

Something is not right and I'm trying to hack through it with something like this:

      if (overrideCheckBox.Checked)
        {
           // in the ProcessingBindingSource at ProcessingBindingSource.Position change the value from 0 to 1
        }
        this.ProcessingBindingSource.EndEdit();
        this.ProcessingTableAdapter.Update(rMSDataSet);
        myDataSet.AcceptChanges();

It is not beautiful nor is it the best way to do it but I have to get this done and I can't figure out the syntax.

Any help would be greatly appreciated.
