ExtractValues method returns null values

[EmpowerIT]

Hi,
I am trying to retrieve the user input from a rad grid input form. For some reasons that I do not want to get into right now, I am using an external button to the grid to trigger the 'save' command. i.e. I am not using a command item.

In the external button event i have the following:

void SaveButton_Click(object sender, EventArgs e)
    {
        foreach (GridEditableItem itm in MasterJobSchedulesGrid.EditItems)
        {
            Hashtable values = new Hashtable();

            itm.ExtractValues(values);
            foreach (Parameter updateParam in MasterJobSchedulesDataSource.UpdateParameters)
            {
                updateParam.DefaultValue = Convert.ToString(values[updateParam.Name]);
            }
            MasterJobSchedulesDataSource.Update();
            itm.Edit = false;
        }
        MasterJobSchedulesGrid.Rebind();
    }

The values returned are always null. I have also tried using the itm.OwnerTableView.ExtractValuesFromItem method, but it also gives me nulls.

Any help would be appreciated.

I solved my own problem.

I was using EditForms instead of InPlace forms, so i needed to pass in the EditFormItem to the ExtractValuesFromItem method
