Something like this works for me:
private void SetPropertyValue(string pstrControlName, string pstrPropName, string pstrValue)
{
Control c = this.FindControl(pstrControlName);
if ( c != null )
{
PropertyInfo pi = c.GetType().GetProperty(pstrPropName,pstrValue.GetType());
if (pi != null && pi.CanWrite)
pi.SetValue(c,pstrValue,null);
}
}Cetin
