Help. ErrorProvider with Databinding not showing

[aboutjav.com@gmail.com]

Hi,

I added an errorprovider to my GUI layer and databinded to my business
object

bindingSource1. DataSource = MyBusinessObjec t;

NameTextBox.Set DataBindings("T ext", bindingSource1, "NameProper ty",
true, DataSourceUpdat eMode.OnPropert yChanged);

The property is the followign


public string NameProperty
{
get { return m_name; }
set
{
m_name= value;
PropertyHasChan ged("NameProper ty");
PropertyHasChan ged("VerifyPers onName");
}
}

The
PropertyHasChan ged("VerifyPers onName");

will check if the textbox.text value is null or empty.

public bool VerifyPersonNam e(object target, RuleArgs e)
{
if (string.IsNullO rEmpty(m_name.T rim()))
{
e.Description = "Empty Field";
return false;
}
return true;
}


When I clear the Name textbox field, i see the e.Description is
called. However, the errorprovider is not visible on the GUI.

Any help is appreciated.

Thanks
