下面是一些更新的代码。这仍然不起作用。在这次尝试中。

1.    ` bs.DataSource = GetData(sql, dgAnalysis);` is stating that cannot implicitly convert type void to object.
2.     ` bs = new BindingSource(ds, DGV); ` is stating that Argument 2 cannot convert from ADGV,AdvancedDataGridView to string. DGV is a variable that contains the name of the datagridview being worked with. See 1. it's working with dgAnalysis, later it's working with dgComponents. I have multiple other datagridview to fill.
private void cmdtb1pg1_Click(object sender, EventArgs e)
    {
        // Get Analysis
        sql = "SELECT DISTINCT NAME FROM LWPROD.ANALYSIS ORDER BY 1";                
        bs.DataSource = GetData(sql, dgAnalysis);    
        dgAnalysis.ClearSelection();            
    }       
    private  void GetData(string sql, AdvancedDataGridView DGV)
    {       
        OracleConnection con = new OracleConnection(connectionString);           
        OracleDataAdapter table = new OracleDataAdapter();
        try
        {
            DataSet ds = new DataSet();
            OracleCommand cmd = new OracleCommand();
            con.Open();
            OracleDataAdapter da = new OracleDataAdapter();
            bs = new BindingSource(ds, DGV);              
        }
        catch
        {                
        }
        finally
        {
            var name = DGV.Name;
            switch (name)
            {
                case "dgAnalysis":
                    dgAnalysis.DataSource = bs; 
                    break;
                case "dgComponents":
                    dgComponents.DataSource = bs;   
                    break;                        
            }           
        }            
    }      `

我有一部分工作要做，我可以将值放入dganalysis，过滤它们，并使用作为第二个查询的参数。在运行第二个查询之后，第一个datagridview将包含3列而不是一列。第二个datagrid视图将包含3行而不是2行，并且查询的解析没有填充第二个查询。

我不知道如何清除数据源和数据网格？我有tried:clearing the bindingsource并重置datagridview的数据源。
