The error I got when I change the datasource of BindingSource
"databinding cannot find a row that is suitable for all bindings row that is suitable for all bindings"
this.RemoveAllBindings(); // My work-around for the meantime
bdsOrder.DataSource = _ds.Tables["orders"]; // errors here on second time around(first time is blank datatable, second time is when i open existing record, then it errors), dataset comes from Remoting
bdsOrderDetail.DataSource = _ds.Tables["order_detail"];
bdsPhoto.DataSource = _ds.Tables["order_photo"];
bdnPhoto.BindingSource = bdsPhoto;
My Helper extension method work-around on perplexing "databinding cannot find a row..." error.
namespace MycComponentExtension
{
public static class Helper
{
public static void RemoveAllBindings(this Form form)
{
RemoveAllBindings((Control)form);
}
private static void RemoveAllBindings(this Control root)
{
foreach (Control c in root.Controls)
{
if (c.Controls.Count > 0) RemoveAllBindings(c);
root.DataBindings.Clear();
}
}
What's the meaning of "DataBinding cannot find a row..." error, if at all possible, can I eliminate my work-around on it?

You also learned that there are two types of data binding as in the following: Simple Data binding: the process of binding a control such as a TextBox or a label. Complex data binding: the process of binding a control such as ComboBox, DataGridView, or ListBox.
Data binding is the process that establishes a connection between the app UI and the data it displays. If the binding has the correct settings and the data provides the proper notifications, when the data changes its value, the elements that are bound to the data reflect changes automatically.
Data Binding Using ADO.NET. Client-Server development. Data Binding. The process of automatically setting properties of one or more form controls at run time from a structure that contains data.
Description. Simple data binding. The ability of a control to bind to a single data element, such as a value in a column in a dataset table. Simple data binding is the type of binding typical for controls such as a TextBox control or Label control, which are controls that typically only display a single value.
I have seen this error when no DataGridView is involved, but my data source was being updated from another thread (naughty!) and my binding had FormattingEnabled=false. Changing both of these seemed to fix the problem.
