I mean that I use dynamic object, the property name will be set at run time. So I cannot use anotation attribute like your link suggestion.
Ex:
MyDataRow source code
And now I want validate each property on MyDataRow. I know I can use RadAlert, but it's not consistency with another form. I want the error message on RadPropertyGrid must be like this:

Ex:
dynamic myDataRow =
new
MyDataRow();
for
(
int
i = 0; i < 1000; i++)
{
myDataRow[
string
.Format(
"Property {0}"
, i)] =
string
.Format(
"Value {0}"
, i);
}
this
.propertyGrid1.Item = myDataRow;
MyDataRow source code
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Dynamic;
using
System.ComponentModel;
namespace
Telerik.Windows.Examples.PropertyGrid.Virtualization
{
public
class
MyDataRow : DynamicObject, INotifyPropertyChanged
{
readonly
IDictionary<

> data;
public

{
this
.data =
new
Dictionary<

,
object
>();
}
public
MyDataRow(IDictionary<
string
,
object
> source)
{
this
.data = source;
}
public
override
IEnumerable<
string
> GetDynamicMemberNames()
{
return
this
.data.Keys;
}
public
override
bool
TryGetMember(GetMemberBinder binder,
out
object
result)
{
result =
this
[binder.Name];
return
true
;
}
public
override
bool
TrySetMember(SetMemberBinder binder,
object
value)
{
this
[binder.Name] = value;
return
true
;
}
public
object
this
[
string
columnName]
{
get
{
if
(
this
.data.ContainsKey(columnName))
{
return
this
.data[columnName];
}
return
null
;
}
set
{
if
(!
this
.data.ContainsKey(columnName))
{
this
.data.Add(columnName, value);
this
.OnPropertyChanged(columnName);
}
else
{
if
(
this
.data[columnName] != value)
{
this
.data[columnName] = value;
this
.OnPropertyChanged(columnName);
}
}
}
}
private
void
OnPropertyChanged(

propertyName)
{

I have the same question. Is there a way to perform validation when using a dynamic object as the item source? The last post was from 2013. Has anything changed on this issue?
