Load all call log records for a quote ProcessCaller/CRMCallEntry

I’ve made a dashboard with a column of buttons, so the user can open the call log for that quote:

The code for the button:

	private void myGrid_ClickCellButton(object sender, Infragistics.Win.UltraWinGrid.CellEventArgs e)
    {
        if (e.Cell.Column.Key == "Calculated_Button")
        {
			Erp.UI.App.CRMCallEntry.CRMCallArgs callargs = new Erp.UI.App.CRMCallEntry.CRMCallArgs(
			"QuoteHed",
			e.Cell.Row.Cells["QuoteHed_QuoteNum"].Value.ToString(),
			"",
			"",
			e.Cell.Row.Cells["CRMCall1_CallSeqNum"].Value.ToString(),
			e.Cell.Row.Cells["Customer_CustID"].Value.ToString()
					);
			ProcessCaller.LaunchCallbackForm(oTrans, "CRGO6100", callargs);
        }
    }

The button correctly opens the call log form, but none of the existing records show. What do I need to do to get the records pulled in automatically?

I had a minor mistake. This worked:

private void myGrid_ClickCellButton(object sender, Infragistics.Win.UltraWinGrid.CellEventArgs e)
    {
        if (e.Cell.Column.Key == "Calculated_Button")
        {
			Erp.UI.App.CRMCallEntry.CRMCallArgs callargs = new Erp.UI.App.CRMCallEntry.CRMCallArgs(
			"QuoteHed",
			e.Cell.Row.Cells["QuoteHed_QuoteNum"].Value.ToString(),
			e.Cell.Row.Cells["Customer_CustNum"].Value.ToString(),
			"",
			e.Cell.Row.Cells["CRMCall1_CallSeqNum"].Value.ToString(),
			""
					);
			ProcessCaller.LaunchCallbackForm(oTrans, "CRGO6100", callargs);
        }
