Hello,

I have an ObjectDataSource with an ID of ObjectDataSource1 on a webpage. I also have a gridview in which I am binding the ObjectDataSource.ID to the GridView.DataSourceID. The problem I get is when text is changed in a textbox, the code calls BrokerageTransactions.GetAllWithDt which returns a DataTable. I want to set this datatable as the DataSource for the GridView, but it is telling me that I can't set the DataSouce and DataSourceId together. How can I fix this? Code is below. Also. Why can't you set a DataSourceID and a DataSource when using an ObjectDataSource?

Thanks, X

protected void BrokerageChange(Object sender, EventArgs e)

                          new BrokerageTransactions();

                 Guid(Membership.GetUser().ProviderUserKey.ToString()), 
                 ddlBrokerageDetails.SelectedItem.Text.ToString());

    foreach (DataRow dr in ds.Tables[0].Rows)
    {
        brokerageaccountdetails.BrokerageId = 
                                new Guid(dr["BrkrgId"].ToString());
    }
